1. De Dosibus Medicinarum

In nomine Patris et Filii et Spirtus Sancti. Amen.

MEDICINARUM QUEDAM SUNT SIMPLICES quedam composite: .i.e. some medicines are simples, others are composites. For Avicenna says that the simples are those with general or local actions, or actions resembling general actions: general actions such as heating, cooling, evacuating, drawing, and the like.

2.

Local actions are truly manifest in aloe socotrine relieving cancer; yarrow relieving hemorrhoids, and dandelion, i.e. scariole relieving jaundice, and the like. Actions resembling general actions as the medicine which promotes the flow of the urine, purges the abdomen, and such like. The reason why actions resembling general actions are so called is that they are the actions of things which are of general advantage to the entire body.

3.

Take note that some of the simples are obtained from minerals, others from plants, and others from animals. Simples obtained from minerals: emerald, sapphire, pearl, and the like are such. Simples indeed obtained from plants: leaves, seeds, roots, stems, blossoms, fruit, and grain are such. Note particularly that it is proper to use the leaves when they begin to have their proper size in full and when they survive in their own shape without change of color and without falling. It is indeed proper to gather the seeds when their size is complete, and when their natural condition and viscidity are seasoned. It is indeed proper to gather the roots when the foliage falls. It is indeed proper to gather the fruit before they fall or before they are ready to fall, when they have reached maturity, because they ought to be gathered in the prime of their strength.

4.

The simple obtained from animals: some of it, indeed, is obtained or usually is obtained from parts of animals, more of it from their superfluities, and more of it from their fluids. From  p.49 parts: such as the gall, livers, and parts in general. From the superfluities such as the urine and the feces. From the fluids such as the blood, the milk, and the rennet. Note particularly that in choosing the cures derived from animals that it is proper to choose the animals which have healthy strong bodies, healthy members and young age.

5.

A composite medicine indeed, as Avicenna says is one compounded from simples or from other composite medicines. For that reason many composites are made from simples and from composites, as is evident from theriac ¹ which is made from simples and from composite medicines for the three things which enter into it are composite medicines. For that reason the composite has character from the simples and character from the entire form. ²

6.

Note particularly Avicenna or Constantinus says in the commencement of his own Antidotarius that the compounding of simples is essential, since for three causes it (a simple) does not suffice for curing every disease. The first cause is on account of the nature of the disease. The second cause is on account of the affected members. The third cause is on account of the nature of the simple. For these reasons the old physicians, when constrained by this necessity, made composite medicines from simples so that they might be able to carry out their intention in every single defect, and to compound with perfection and advantage.

7.

The operations of a composite medicine in relation to the nature of the diseases are determined by four conditions or causes. The first of these causes: from the variability of the extent of the evil complexion. ³ The second cause: from the extent of the disease. The third cause: from the different qualities of the disease. The fourth cause: from the conflict of the different diseases.

8.

Let the medicines be compounded according to the extent of the diseases of similar and dissimilar evil complexions, as is plain when a bad hot or cold complexion of the body is found together with some quantity which cannot be changed by a single simple only. For that reason it is necessary to make from different simples, used in the same proportions, a single composite medicine which can combat with the quantity of the evil complexion of the body. For example, should the body be of an immoderately high temperature of the second degree, and should no contrary cold simple of the same degree be procured let two simples be procured, i.e. a hot medicine of the first degree and a cold medicine of the third degree. When these are mixed and compounded in this way they will be cold in the second degree.

9.

Because of the extent of the disease, let the medicine be compounded; for when the disease is great and dangerous it is necessary to compound two simples or more, so that when they are compounded the disease is destroyed by them. Because of the varying quality of the disease, let the medicine be compounded, for when the disease has contrary forces it is proper to compound the medicine of contrary things. For example, as is evident in the case of phlegmon ⁴ for which is suitable a compound medicine such as a dispersive, and a cooling medicine.

10.

Because of the conflict of the different diseases, let the medicine be compounded, for when any disease has been developed from different items according to nature and quality it is necessary to expel it by a medicine which is correspondingly different as regards nature and quality. According to Constantinus, should theriac be compounded from numerous simples the reason for it is that it has the power to combat pestilential diseases and deadly poisons.

The second of the four causes, which cause is based on the affected members: governed by two circumstances let the medicine for this be compounded. First  p.53 circumstance concerns the location of the members. The second circumstance concerns their nobility.

11.

Let the medicine indeed be compounded in accordance with the remoteness of the location for it is obvious, should the affected part be far away from the stomach where the medicine is first received, it is necessary for the medicine to be compounded so that it is not very much weakened by the distance to the extent it would not be possible for it to penetrate as far as the member. For that reason eastern saffron is put into the medicines, since it causes them to penetrate swiftly and easily to the members.

12.

Let the medicine be compounded in accordance with the delicacy of the member for it is obvious as Galen says, if there is an ulcer on the liver, which is a noble member, that it is necessary to compound a medicine from savory dispersives and from styptics so that the virtue of the noble member is preserved by the savory things, and that the styptics might not permit the substance of the noble member to be dissolved by the dispersives.

13.

The third of the four causes, which cause is based on the nature of the simple: let this be realized from eight circumstances. First of these circumstances: offensiveness of the medicine. Second: lowering of its potency. Third: to correct its harmful effect. Fourth: to strengthen its virtue. Fifth: to lower or lessen its virulence. Sixth: to preserve its own quality. Seventh: the variability of the items by which the action is accomplished. Eighth: the lack of comfort afforded by the simple itself.

14.

As regards the offensiveness of the medicine: let the medicine be compounded so that when its taste is offensive and when it is not possible to take it or retain it in the stomach a fragrant and savory medicine is mixed with it to destroy its offensiveness. For that reason Hippocrates said to mix wild carrot with black hellebore, and Galen said to mix anise with  p.55 scammony.

To lower high potency of the medicine, let the medicine be compounded when it is too powerful. As for example, opium which is cold in the fourth degree is compounded, so as to reduce its excessive coldness, with castoreum which is hot.

15.

To correct the harmful effect of the medicine: let the medicine be compounded when it is contrary to the disease and when it has an evil effect on the member where the disease is located; as for instance scammony which harms the stomach and liver, so that it is necessary to mix black pepper and anise with it.

To strengthen the medicine: let the medicine be compounded when it is weak as is obvious in the case of iris being mixed with theriac, and acorus ⁵ with agaric.

16.

To reduce its power: let the medicine be compounded; for when it is too hot, too sour, another medicine is mixed with it which reduces its heat and its piquancy, as is obvious in the case of gum arabic which is mixed with theriac.

To preserve the virtue of the medicine so that it might not become putrid: let the medicine be compounded for it is necessary for the physician to keep a time record of the medicines over a long period of time. For this reason, so that their virtues might not depart, it is necessary to mix another item with them to preserve their virtues, as is obvious from opium which is mixed with other composite medicines.

17.

From the variability of the items by which the action is accomplished: let the medicine be compounded, for when the physician does not find a lone simple contrary to the disease another medicine is mixed with it, because, as is evident from the plasters, it is necessary to mix wax, oil and pitch into them, so that they would more easily, or more likely adhere to the member.

18.

The lack of relief through the simple: let the medicine be compounded for when universal relief for the disease is not found in the lone simple it is necessary to compound dissimilar contrary medicines, and to make one medicine from them, as is obvious from the wounds for which a healing medicine and a flesh-growing medicine are required to be compounded, such as the medicine compounded from myrrh, incense, and the likes. So therefore, it is necessary for the rational physicians to make a composite medicine from the simples. It suffices for us what we have said about the simples.

Before we speak of the composite medicines it is necessary first of all to speak of the estimated quantity of the simples which are to be put into the composite medicines, for Constantinus says, “Since the medicine varies in its qualities, in its efficacy, and in its virtues it is necessary to include a little of some medicines, much of others and of still others a medium quantity.”

19.

There are two principles according to which the dosage of simples used in compounding is regulated; i.e. one concerning the simple, and the other concerning the composite medicine itself.

As regards the simple: let that be subdivided into seven cases. First of these cases the strength or weakness of the virtue of the cure. Second: greatness or littleness of its efficacy. Third: nobility or ignobility of its efficacy. Fourth: combining one medicine with another giving ease, or leaving it by itself. Fifth: location of the affected member. Sixth: evil effect of the simple. Seventh: when an item is compounded into a composite medicine which item diminishes the efficacy of the other item contained therein.

20.

It is thus the dosage is determined: according to the virtue of the simple, for should the medicine be too hot such as euphorbium is, or too cold such as opium is, it is necessary to put a little  p.59 of it into the composite medicine. Should it be weak of heat such as rhubarb is, or cold such as myrobalani citrini is, it is necessary to include much of it.

21.

Dosage determined by the greatness or littleness of the efficacy: should the medicine possess great efficacy much of it should be put into the compound, as is obvious by putting iris with agaric. Should its efficacy be little, it is proper to include only a little of it in the remedy.

22.

Dosage determined by the nobility of the efficacy: much more of it should be put into the medicine in that case, than when its efficacy is ignoble. Efficacy of the medicine is called noble when the principal or noble members are strengthened, as in the case of emerald in strengthening the heart and galangal in strengthening the stomach, and spodium. ⁶ in strengthening the liver. Therefore, it is necessary to put much of these into the composite medicine.

23.

Dosage determined by combining the efficacies, as is obvious when there is in the medicine a simple which has not properties except along with another medicine, it is proper to put much of that medicine in the compound; such as violet which has not properties for inflammation of the liver except together with santal and with rose. For that reason it is proper to put much of santal and of rose along with it.

24.

Dosage of the medicine determined by the location of the member: let it be varied, for should the affected member be remote from the stomach it is necessary to put much of the medicine which relieves it into the compound; and should it be close to it let there be little of it put into it.

25.

Dosage of the medicine determined by its evil effects: let it be varied, for should any medicine be equally good at assisting a particular member and at doing harm to other members, it is proper to put little of it in, such as in the case of camphor which does good to the liver and harm to the brain.

26.

Dosage determined from compounding the medicine: let it be varied, for should there be a compound in which there are contrary ingredients, one of which ingredients diminishes the efficacy of the other, it is necessary to put much of the efficacious and little of the harmful medicine into it. These are the conditions for the dosage of the simples which are put into the composites, and it is in accordance with these conditions we prescribe what follows.

Note, that the conditions to be observed are the same in the doses of the simples and in the doses of the composites. Note also that some of the laxatives are uncompounded and others are compounded.

27.

The laxative simples: indeed some of them such as scammony become weak on infusion, others such as myrobalan become concentrated, and some others such as cassia fistola become refined. For Constantinus says that every medicine which purges by its attractive force contains matter too poisonous and contrary to nature, so for this reason it is necessary for the physician when he administers it to do everything with reason and to administer it according to the virtue, season, appearance, and age; and to administer it in a safe and reasonable way so that the body may not change from its own complexion to another worse complexion, and may not die.

28.

As for example if scammony were given in too large a quantity, or if it were spoiled, or if given alone, or when compounded with another medicine which heightens its sourness (géire: intensity), or if given in the summer time, it purges actively and drastically, lowers the natural temperature, leads to syncope, and constricts the cardiac valve (bel an goile: opening of stomach; cardia.) particularly should it be phlegmatic humor which dominates. However, should it be given in a moderate quantity, when itself is in a fairly good condition and corrected by anise or by mastix, or when boiled into pasty which moderates its sharpness, then it is of benefit if administered to women in. their youth, and to those dominated by  p.63 choler; then it is reasonable to administer it. Let the same be understood for the other laxatives.

29.

Note particularly that there are some of the simples such as scammony, rhubarb, and reuponticum ⁷ which purge choler by means of their attractive force. However, when you desire to administer a medicine of scammony do it in this way: take two or three drams of scammony and pulverize it, but do not break it too fine such as the other spices, for by its subtility and adhesiveness it would penetrate to the recesses of the stomach, and in this way it would be possible for it to do harm. So administer it in the dose we are prescribing later, when it has been compounded in the manner we have told of already.

30.

Scamonia quidem est sucus cuiusdam volubilis: ⁸ i.e. scammony is the extract of a species of honeysuckle, i.e. a herb which grows to the east of the ocean. It is a species of tithymallus and its efficacy lasts for thirty years, glecio ⁹ i.e. choice. This is the most stable species of it, the species which is variegated as it becomes brighter, and which is very brittle or easily broken.

31.

Nature: it is its nature to be hot and dry in the third degree. It purges choler from the remote members and from affection of the stomach and liver and from those who have a nervous nature. When being administered let it be corrected with a scruple of mastix which has been pulverized and compounded with it. Or if it be a person who has a hot complexion, let the scammony along with the powder we have spoken of, be put into a pear or raw apple, the center of which has been hollowed out, let pasty be put around it, and let it be put in an oven or to the fire to roast. Afterwards let it be taken out of the apple, dried in a dark place, and then administered. Because of the speed with which it creates dysentry, and stomach-trouble it is not proper for that reason to administer it in affections of the stomach and of the liver, unless they should be chronic. If so, let  p.65 the species which is best be chosen.

32.

Here is a rule whereby it is not proper to administer a medicine containing scammony in case of bad hot complexion of the stomach, liver, gall, or kidneys. Dosage: its minimum dose one scruple, and its maximum dose two scruples. Note particularly, Galen says that the best species of it is the species which comes from Antioch and which has a color that tends towards being light. It is the one which is the easiest to break, the one which when broken has a color like glass. Note particularly, whether by itself or with another medicine, that it is proper to administer it in the dose we have spoken of.

33.

Reubarbarum quidem ut quidam dicunt est radix cuiusdam arboris: i.e. rhubarb according to some is the root of a tree. It is found resembling a lump. Note particularly that there is a rhubarb called barbarum which is found in barbarian countries such as India and the countries east of the ocean, and another rhubarb called ponticum because it is found on an island called Pontos, or because of its pontic ¹⁰ taste. And there is another yellow species of it which is mixed with some black and which has firmness, ponticity ¹¹, bitterness and piquancy. Nature: they all have the same nature and they are hot and dry in the second degree. They purge choler from the stomach and from the liver and are for that reason suitable in diseases of the stomach and of the liver an example of which is fever. Dosage: it suffices as maximum dose of it by itself or in a syrup up to one half ounce; and as minimum dose of it up to two drams.

34.

Reuponticum: hot, dry, and in the second degree. It is very similar to rhubarb, and is best when it is heavy and round and has distinct veins. It purges choler of the stomach and liver. However, it does not stain as rhubarb does, and is suitable for disease of the stomach and liver. Should it be administered with extract of fennel it removes  p.67 obstructions of the spleen. When by itself, or with another it suffices as maximum dose of it up to one ounce or one half ounce, or as minimum dose up to two drams.

35.

DICTO DE MEDICINIS SIMPLICIBUS attractivis purgantibus coleram dicendum est de medicinis simplicibus attractivis purgantibus flegma: i.e. having spoken of the uncompounded attractives which purge choler it is meet that we speak of the attractive simples such as colocynth, turpeth, agaric, hermodactylus, esola, euphorbium, and white hellebore, which purge phlegm.

36.

Colocynthis quidem est pomum cuiusdam arboris et cetera: i.e. colocynth is a hollow apple or fruit of a tree which grows in the Orient around Jerusalem, and which has as a synonym cucurbita alaxandrina. Nature: it is hot in the third degree and dry in the second degree. Primarily it purges gross dense phlegmatic humor from the joints with acuteness by its attractive force. Secondarily, it purges melancholia from the brain . Because of that it is suitable for ailments of the head such as melancholia, epilepsy, and the likes. Since it causes, when it is administered, great discomfort to the stomach, vomiting, and syncope, it is proper for that reason to correct it, before it is administered, by a scruple of pulverized tragacanth compounded with it. Let it not be administered in hot weather and let it not be mixed with another powerful laxative. Dosage: its maximum dose singly or together with another medicine one dram; and its minimum dose up to one and one half scruples. It is best when it has an abundance of bright uniform pith.

37.

Turpethum quedem est radix cue ultra mare reperitar: i.e. turpeth is a root found east of the ocean. It is choicest when it is intermediate between thick and thin, when it is bright and gummy at the tops, and easy to break. When placed in the mouth it hurts the tongue. So that it might not  p.69 penetrate to the stomach and the liver it is proper to correct its malignancy by rubbing it first in oil of rose ¹² and oil of sweet almonds. Nature: hot and dry in the third degree. It purges phlegmatic humor without repugnance on the part of the stomach, intestines, liver and loins. Dosage: it suffices as maximum dose, individually or with another medicine, four drams; and as minimum dose, from one to two drams. Let it be compounded with a dram of sugar together with a dram of ginger so that it does not injure the stomach by its sourness.

38.

Agaricum est sicut fungus: i.e. this is what agaric is: a thing which is similar to a fungus. It is found in Babylon and is of two forms, i.e. the male and female. The form of the male is long and not so brittle or so bright as the female form. The feminine form of it is bright, light, fragile, and is knotty on the outside and in the inside. It contains something which resembles hair. The male form is uniform, and not so brittle or so light-colored as the other. This is how it should be chosen: it should be bright, and easily broken. The male form of it is no good. However, Avicenna says that both of them are very bad. This is how the statement of Avicenna is interpreted; namely, as regards to the land where he actually was, for it was malignant and harmful there. Moreover, according to Johannes Ibn Mesue this is a most beneficial medicine since it purges every member of the body in general.

Nature: hot in the second degree, and dry in the third degree. It purges phlegm from the stomach primarily and melancholia secondarily; and for that reason is suitable, together with a draught in which saxifrage, i.e. meadow saxifrage, has been boiled, for quotidian fever caused by natural phlegm, and for dysentry or dysuria caused by phlegm . Together with a draught in which ragwort is boiled, it promotes the catamenia .

Dosage: the maximum amount which it is proper  p.71 to administer whether singly or with another medicine is up to four drams and it is proper to administer as its minimum dose from one and one half drams to one dram. Before administering it it is proper to correct it with one dram of extract of licorice.

39.

Helleborus quidem est radix calida: i.e. hellebore is a hot root. It is of two species, i.e. a bright species and a dark species. The bright species indeed is the skin of a root which resembles the root of althea. It is best when it has a smooth surface, and when it is bright and easily broken. Nature: hot and dry in the middle of the second degree. It purges thick phlegm, and should it be pulverized and put in the nose it clears the brain by dispelling the superfluities. It rids the stomach of phlegm by causing vomiting. The ancients were accustomed to put hellebore in their purgatives just as we now are accustomed to use scammony.

Dosage: it suffices as the maximum amount of it, singly or with another medicine up to one and one half scruples; and the minimum amount up to one half scruple. Before administering it, its malignancy is corrected by one dram of origanum or catnip which has been pulverized and compounded with it.

40.

Esola quidem est frutex: i.e. esola is a brush and it is its root which serves as medicine. Nature: hot and dry in the third degree. It has the virtue of depleting the phlegmatic humors primarily, and for that reason is useful for every disease caused by natural phlegm such as arthritis, podagra, chirogra, paralysis, iliac ¹³, and leucophlegmansia.

Note that of the items which purge through their sourness, next after scammony esola is the best. It is administered in one of the oils because of being too objectionable. For that reason every medicine which purges phlegm is made sour by it, or it is possible to make it sour with esola.

Dosage: it suffices as maximum dose of it, singly or with another medicine, one dram; and the  p.73 minimum amount, singly, from one to two scruples.

41.

Euphorbium quidem est gumme arboris: i.e. euphorbia is the gum of a tree which grows in India, and which exudes gumminess in the summer time. When it has coagulated around it, it is changed to euphorbium matter.

Nature: hot and dry in the fourth degree. It purges phlegm primarily, and melancholia secondarily. For that reason it relieves all arthritis, podagra, chirogra, iliac, lethargy, and epilepsy. The pills made from it relieve paralysis, and should they be mixed with various spices they relieve the diseases we have mentioned. It is best when it is bright, fresh, and yellow tending towards green.

Dosage: it suffices as maximum dose of it from one scruple to one half scruple, and the minimum dose of it up to one quarter scruple. For Avicenna says that three drams of it kills a person in three days by injuring the stomach and entrails. It is proper to mitigate its powder with oil of rose.

42.

DICTO UT DETERMINATIO DE MEDICINIS simplicibus attractivis qui phlegma evacuant, et cetera: i.e. after speaking of the uncompounded attractives which deplete phlegm, it is right to speak of the uncompounded attractives such as polypodium, lapis lazuli, lapis armenicus, senna, and black hellebore which purge melancholia.

43.

Polypodium quidem est herba similis filici i.e. polypodium is a plant resembling fern which grows on oaks, rocks, walls and stones. The best specie of it is that which grows on the oaks. Its root is best, and it is good while getting green. According to the Antidotarium it is called a knotty stick of the color of ashes, which becomes darker or redder. It is better growing red rather than yellow, and when it is firm, green, and fresh.

Nature: hot in the second degree and dry in the third degree. It purges phlegm primarily, and melancholia secondarily, without hurting or wounding.  p.75 Should it be comminuted along with sugar it purges the abdomen without pain. Note that when it is boiled it is proper to put along with it some item such as anise or fennel seed which expels flatus, because polypodium releases the humors in excessive flatulence. It is suitable for quotidian fever, iliac, alopecia, and arthritis. Dosage: it suffices as maximum dose of it one ounce; and as minimum dose to one half ounce.

44.

Lapis Lazuli: a blue stone, cold and dry in the second degree. Its color is very like the color of the heavens, and in it are small particles of the color of gold. It purges a certain melancholia, and for that reason is suitable for those having quotidian fever, for those having hemorrhoids, for ailments of the spleen and is convenient for every kind of melancholic humor. It is bad for the stomach. When washed it promotes vomiting without ill effect. Dosage: it suffices as maximum dose of it two scruples; and as minimum dose one scruple. Note that the method of washing it is to put it into a silver cup or other strong vessel, to crush it with a pestle, in a mortar and to mix it with water afterwards until it is made muddy. Then, let it be poured off, let more water be added to it, and let it be done in this way ten or twenty times. Others say to wash it thirty times. The sign that it is well washed is when the water is no longer affected. Note particularly that it is not proper to administer lapis lazuli in a draught since it would sink to the bottom, but to give the draught first, and when it has operated five or six times to administer along with syrup of violet the lapis lazuli which has been washed. The manner in which it then purges melancholia is remarkable.

45.

Lapis Armenicus: i.e. a stone in which there is something of the color of lazuli. It is smooth to touch. It is called Lapis Armenicus for the reason that it is found in Armenia. It has a somewhat bright color and has less gravity than  p.77 lapis lazuli.

Nature: cold and dry in the second degree. It purges phlegm more effectively than lapis lazuli does. For that reason it is suitable for quartan fever, and for every melancholic disease. Avicenna says it is bad for the stomach. However, should it be washed it does not nauseate, should it not be, it does. The dose is the same as for lapis lazuli.

46.

Senna quidem est herba que intrans marinus partibus crescit: i.e. senna is a herb which grows east of the ocean, particularly around Babylon and Arabia. Nature: hot and dry in the second degree. It purges melancholia primarily, and choler secondarily. For that reason it specifically purges or relieves melancholia, epilepsy, syncope and colicus. ¹⁴ It strengthens the heart, and is suitable for diseases of the spleen and liver, and for hemorrhoids and quartan fever. Note that the foliage of the senna is better towards the action of the cure than its blossom. Dosage: it suffices as maximum dose, when administered singly, one ounce; and should it be given with other laxatives from three to four drams.

47.

Helleborus niger, et cetera i.e. black hellebore is in chips when cut. Its piquancy is more powerful than that of white hellebore. The people who cut it are saved from its evil effects in this way: by taking garlic and wine. It is best when it is intermediate between young and old, when it has a yellow color, and when it is brittle. Nature: hot and dry in the second degree. It purges melancholia, and is for that reason suitable for impetigo, serpigo, and leprosy. Dosage: it suffices as maximum dose of it up to one half dram; and as minimum dose up to one half scruple. Before administering it, it is proper to correct it with origanum or catnip.

48.

DICTO DE MEDICINIS SIMPLICIBUS attractivis, et cetera: i.e. having spoken of the simples which purge by attractive force, it is meet that we speak of the simples which deplete the humors by compression. Myrobalan is one. There are five kinds of it: citrini, chebuli, indi, emblici, and bellerici. ¹⁵ Nature: all of them are cold and dry in the third degree. They are the fruit of different trees. They are good when gummy, because by their gumminess they purge. It is said that the citrini are hotter than the inndi, and that the inndi are less cold than the chebuli. Of them the citrini purge most; for that reason it is proper to speak of them first.

49.

Citrini solunt coleram rubiam: i.e. the citrini purge choler primarily; and according to Avicenna, a little of phlegm. For that reason when administered in water in which rose and myrtle have been boiled it is suitable for those who have jaundice, tertian fever, and dysentery. However, should it be necessary to cause depletion by myrobalan, let it be done in fear and with caution. For that reason it is proper to mix tragacanth with it, so that it does not aggravate ulcers of the intestines. Dosage, maximum dose of it when given in a draught for dysentery, four drams; and when given for tertian fever, one ounce indeed is the maximum amount.

50.

Note particularly as Avicenna says that it is not proper to administer myrobalani in obstructions of the liver and of the spleen because of the styptic properties which they possess since they purge the thinnest portion of the matter and the thickest portion remains. This is converted into calculous concretion, and in this way the obstructions are increased.

Note that the dosage of the myrobalani is varied according as they are put into draughts or into pills. For should they be put into pills it is proper to put as much as two drams; and should they be in draughts it is proper to put one and one half ounces.  p.81 When they are given in pills it is proper to administer them at night, and if as a draught in the morning. Rhazes says that it is proper to administer the draughts at night should the weather be warm such as the dog days are.

51.

Chebuli: they are cold and dry. They are colder than the citrini. Because they are conducive in the least portion towards bitterness, they are the least laxative and the most costive. Through their properties they purge choler and melancholia. According to Constantinus and Avicenna they purge melancholia and phlegm and they astrict in some way the flux of the stomach. For that reason they are suitable primarily for quartan fever, and secondarily for tertian fever; and when roasted and administered with extract of yarrow they are suitable for the discharge from piles, i.e. hemorrhoids. Since they clear off choler they are for that reason suitable for blindness and weakness of eyesight caused by the nature of the phlegm. It is proper to make a conditement of them with syrup of violets. Whether administered in draught or in pills their dosage is the same as for myrobalani citrini.

52.

Inndi, likewise, are cold and dry. They are close to cebuli in their operation and in their virtues. They purge choler more than cebuli do, and for that reason the diseases they relieve and the method of administering them are the same. Dosage: it suffices as maximum dose of them, if administered in draught, from eight to ten drams; and if in pills from two to three drams.

53.

Emblici: they are cold and dry, having in their virtues and in their actions resemblance to chebuli and to inndi. For that reason their character and dosage are the same, and the diseases which they are of use to are the same. So, likewise, of bellirisi.

54.

DICTO DE MEDICINIS QUE LAXANT com comprimendo dicenda est de medicinis que laxant leniendo: i.e.  p.83 having spoken of the medicines which deplete by compression it is meet that we speak of the medicines such as violet, prune, cassia fistola, and manna which purge by lubrication. ¹⁶

55.

Uiola, i.e. blossom of the violet: cold and moist in the first degree. It purges choler from the stomach, liver, and intestines, for it has moistening, lubricous, cooling, and laxative effect. For that reason should it be made into a syrup; it relieves inflammation of the liver greatly. This syrup is suitable, also, for severe cough, as it soothes the chest, allays pain and febrility of the body in general and of the head in particular. For that reason it is suitable for headache caused from choler, or from sanguine humor.

56.

Pruna: they are identified as plums. ¹⁷ Nature: cold at the beginning of the second degree, and wet at the end of the third degree. The darkest species of them is the best for medicine, especially the species called damasenica, called so after a country. When they are collected ripe they have the virtue of cooling and lubricating the intestines, and are for that reason suitable for high fevers and for constipation of the abdomen when caused by dry or hot humors. Avicenna says that all confections in which they are operate on, or purge choler all the more efficaciously and that they (prunes) purge more readily when wet than dry. They may be administered in draughts in accordance with the  p.85 greatness or littleness of the choler. Should it be little let ten of them be given as a dose; and if great from fifty to one hundred depending on the costiveness, i.e. the stoppage of the entrails.

57.

Cassia fistola alia est cebula alia innda: i.e. there is a species of cassia fistola called cebula, and another species called innda. The best way to procure it is from reeds, and indeed from those which are the most fleshy, the best looking, and the smoothest.

Nature: it is medium between hot and cold, and it is wet. It purges inflammatory humor (i.e. burnt red bile) from the stomach primarily, and phlegm secondarily. It lubricates and evacuates the abdomen without harm or hurt, so that it is suitable for pregnant women. It clears the liver, and for that reason according to Avicenna it is suitable for those having jaundice, headache, tertian fever, and for the severe diseases, and for every disease caused by choler. It purges the remote parts.

Dosage: the minimum dose of it is one half ounce, and the maximum dose up to two ounces.

58.

Manna quidem est ros cadens super lapidem aut arborem: i.e. manna is ros or a dew which falls, under the appearance of honey, on stones, or trees. It becomes sweet, congeals, and dries like gum.

Nature: it is medium between hot and cold. It purges the abdomen, wipes out the acuteness of choler fever according to quality and is suitable for sufferers from choler. The dosage is the same as for cassia fistola.

59.

Tamarindi, i.e. the bitter dactali. They are best when soft and fresh and when they have genuine bitterness. They purge choler and are suitable for fevers, especially when it is necessary to lubricate the intestines. The dosage in draughts is the same as for cassia fistola and manna.

60.

DETERMINATIO DE MEDICINIS simplicibus laxativis et de dosi earum et cetera: i.e. having spoken of the laxative simples and of their doses it is meet to speak of the laxative and digestive compounds  p.87 and of their doses. Take note that there are four necessary conditions for purging the evil humor. Of these conditions the first is: to choose the medicines by which it will be purged. The second condition: to observe the period of the digestion of the humor. The third condition: to observe the quantity of the humor and of theevacuation. The fourth condition: to observe the member where the evil humor is located. To continue, I say that it is necessary first for the physician to choose the medicine. There are two medicines: digestive and laxative. Because it is proper to administer the digestive sooner than the laxative, it is proper for that reason to speak of it first.

61.

Let the digestive be diversified by reason of the diversity of the humor and of the member; for if the humor is dense it is proper to digest it with a tenuating (i.e. emollient) medicine, just as it is evident that it is proper to digest natural phlegm with simple oxymel. Should it be dense or highly viscous it is proper to digest it with a medicine which accelerates it. Should it be natural melancholia let it be digested with oxymel of squill. Should it be a hot humor ¹⁸ it is proper to digest it with a cooling medicine; for instance, choler is digested by oxysaccharum. Should the humors be cold it is proper to digest them with medicine which heats them; for instance, phlegm is digested by simple oxymel. Note that should the humors which it is desired to digest be a compound it is proper that their digestive be compounded. Should the composition of the humors be of equal proportions, it is proper to compound the digestives in equal proportions so that there might not be more of one ingredient in it than there would be of another, as is obvious in the case of acidic phlegm and salty phlegm.

62.

Let the digestive, indeed, be diversified in accordance with the diversity of the members for should the phlegmatic humors accumulate in the head and in the nerve centers as is obvious in paralysis, epilepsy,  p.89 apoplexy and hemicrania (i.e. migraine) it is proper to digest them with a medicine most appropriate for the brain and for the evil humor dominating there. Therefore, it is proper to digest with this oxymel the phlegm which causes paralysis: take acorus, maratrum, lavender, hyssop, polycaria major, every species of nasturtium, ground ivy, betony, origanum, pennyroyal, savory, avens, marjoram, peony, garden rue, ragwort, squills, of each item half a fistful; savin and primrose, of each three whole fistfuls; honey, two pounds. Let an oxymel be made from them.

63.

Note particularly that it is the same digestive by which it is possible to digest the matter in epilepsy and apoplexy, and in hemicrania from a cold cause; however, it is proper to put more of peony, rue, betony and ground ivy than of other items towards digesting the matter in epilepsy. So too for apoplexy. It is proper to digest the matter in hemicrania by the same digestive. However, it is proper to insert more of polycaria major than of the other items, since the herbs employed in the greatest quantity are the most effective in the compound, and are the most appropriate for the area where the matter is located. For that reason more of these is inserted than of the other items.

64.

Should there be in the respiratory organs such as the chest, lungs, and the like an accumulation of the phlegmatic humors without fever, let them be digested with this compound: take calamint, origanum, roots of lily, iris, pennyroyal, maidenhair, of each a fistful; licorice which has been cleaned, maratrum, and cottonseed, of each one ounce; camomile flowers, and mellilotus, of each one half ounce; violets two ounces; sugar two pounds. Let a syrup be made from them.

65.

Should they be dry humors which accumulate there, let them be digested by this medicine: take maidenhair, maratrum, fennel seed, anise, endive, scariole, fresh hyssop, hart's tongue, ceterach,  p.91 maidenhair-spleenwort, and adiantos, of each a fistful; jujube, sebesten,  ¹⁹ and the four cold seeds ²⁰ which have been cleaned, of each half of one ounce; sugarcandy, penedian-sugar ²¹, and white poppy seed, of each one ounce; white tragacanth, gumarabic, and borage blossoms, of each four drams; violet, two drams; sugar, two pounds. Let a syrup be made from them.

66.

Should the choleric humors accumulate in the stomach, liver, or the like, let them be digested by the following medicine: take endive, scariola, liverwort, dandelion, and chicory, of each item three fistfuls; acorus, maidenhair, ceterach, and maidenhair-spleenwort, of each item a fistful; violets three ounces; prunes fifty; rose, lettuce seed, endive seed; white and red sandalwood, and spodium, of each item one ounce; the four cold seeds, of each one half ounce; barberry, i.e. the tree, one half ounce; of borage blossoms two ounces; of wine of pomegranate one half ounce; of sugar two pounds. Let a syrup be made from them.

67.

Should they be phlegmatic humors which accumulate in them (stomach, etc.) let them be digested by this medicine: take eupatorium, i.e. mugwort, and sage, of each ingredient a fistful; camomile, mellilotus, fennel root, parsley, bruscus, asparagus, cinquefoil, i.e. five leaved, gramen, i.e. male grass, germander, bugle, iris, pes columbe i.e. a species of herb-robert, bitter eryngo, comfrey, bogbean, scariole maidenhair, elecampane, and bugloss, of each item one and one half fistfuls, honey and sugar of each one pound; wine of pomegranate one half pound. Let a syrup be made from them.

68.

Should natural melancholic humor accumulate in the spleen, or in the other members let it be digested by the medicine by which the phlegmatic humors in the liver and in the kidneys are digested. Let there be put into it, however, more of hart's tongue, eupatorium, the roots of kapper (caper), the inner bark of tamarisk, and the bark of ash and broom.

69.

Should there be feverish humors in the spleen let them be digested by this medicine: take extract of scabious, extract of fumitory, extract of borage, of each item two pounds; scabious, fumitory, daffodil, fresh thyme, plantain, bugloss, hound's tongue, chicory, hart's tongue, endive, and scariole, of each item a fistful; roots of kapper (caper), two species of sticados rose ²², endive seed, lettuce seed, of each one half ounce; violet, and borage blossoms, of each three ounces; sugar two pounds; wine of pomegranate one half pound. Let a syrup be made from them.

70.

Should phlegmatic humors accumulate in the kidneys, bladder, or in such like members, let them be digested by this medicine: take roots of parsley, yellow flag, filipendula, and creta marina (i.e. rock samphire, sea holly, or sea fennel), of each item three fistfuls; two species of pepperwort, thistle of the sea and field, cinquefoil, grass and garden celidonia, take of each one fistful; gromwell, and fennel seed, of each item one half ounce; seeds of parsley, yellow flag, bruscus, asparagus, and mallow, of each item one ounce; honey and sugar, of each one pound; wine of pomegranate one half pound. Let a syrup be made from them.

71.

Should they be hot humors which accumulate in the same members let them be digested by the medicine by which the hot humors dominating in the members, or in the liver are digested. Let there be put in the medicine, however, more of roots of parsley, cinquefoil, asparagus, bruscus, and fennel.

Should phlegmatic humors accumulate in the womb, let them be digested by the medicine by which the phlegmatic humors of the kidneys are digested. Let there be inserted, however, more of ragwort, calamint eryngo, iris, lily and betony.

Should they be hot humors which accumulate there let them be digested by the medicine by which the hot humors in the kidneys are digested. Let there be put into it, however, more of ragwort.

72.

Should phlegmatic humors accumulate in the  p.95 joints let them be digested by this medicine: take extract of yew one pound; yellow bugle, and ragwort, of each item one fistful, iris, eryngo, lily roots, acorus, endive, maidenhair, and adiantum, of each item one half fistful; camomile flowers, mellilotus, maratrum, bruscus seed, and asparagus, of each item one ounce; rose, licorice which has been washed, lettuce seed, of each item one half ounce; honey and sugar of each one pound. Let a syrup be made from them.

73.

Should they be hot humors which are present there, let them be digested by a medicine that has been compounded of endive, scariole, hart's tongue, extract of yew, yellow bugle, ²³ violet, camomile flowers, mellilotus, rose and lettuce seed. Let a syrup be made from them. Note particularly that should complex humors enter the same members it is proper to digest them with compound medicines depending on the diversity of the humors and of the members. This is sufficient now to say in connection with the digestives.

74.

DICTO DE MEDICINIS DIGESTIVIS dicendum est de medicinis laxativis composites: i.e. having spoken of the digestives it is meet to speak of the compound laxatives. Note particularly that the compound laxatives are diversified according to the diversity of the humors since some of them such as yera pigra ²⁴, benedict, ²⁵ blanca ²⁶, theodoricon anacardium ²⁷, stomaticon laxativum, arthetice pills, auree pills, asafetida pills, euphorbium pills, sweet electuary, ²⁸ cochie pills, and paulinum purge especially phlegmatic humor.

75.

There are other medicines such as catarticum imperiale, yera Rufini, diasenna, triffera sarracenica, yera logodion ²⁹ teodoricon hyperiston which purge melancholic humor in particular. There are still other medicines such as electuary of sugar of roses, and diaprunis which purge choler in particular. Let the medicines be varied according to the diversity of the members. Although benedicta and yera pigra  p.97 have the virtue of purging phlegmatic humor. It is phlegmatic humor of the kidneys, however, which benedicta most suitably purges, and for that reason it relieves nephritis. Yera pigra purges phlegmatic humor of the head and for that reason it relieves complaints of the head caused by phlegmatic humor.

76.

benedicta is so called for the reason that it is blessed by each person who uses it. It is suitable for gout, arthritis, and podagra caused by phlegmatic humor; and it clears the kidneys, the loins, and the bladder.

Yera pigra is so called for the reason, indeed, that ιερα and sacer are identical, i.e. blessed; and that πικρα and amara are identical, i.e. bitter. It is suitable for various complaints of the head, ears, and eyes; it clears the stomach and eyes. It cures affliction of the spleen very effectively and diseases of the womb as well.

77.

Blanca is so called because blancam and white thing are the same. This because it purges the white humors, i.e. the phlegmatic humors . For that reason it is suitable for cephalalgy caused by phlegmatic humor, for sore eyes, for paralysis, and for epilepsy.

Theodoricon anacardium is so called because of the fruit named anacardium which enters into it. It purges phlegmatic humor of the head effectively, and, in particular, the back portion, and for that reason refreshes the memory. It cures vertigo, and is suitable, likewise, for diseases of the womb which come from a cold cause.

78.

Stomaticon laxativum and sweet electuary purge phlegmatic humors of the stomach specifically. Arthetica pills purge phlegmatic humor of the joints specifically, and for that reason relieve arthritis, chiragra, and podagra. Auree pills purge phlegmatic humor of the head specifically. They sharpen the eyesight  p.99 specifically, and are for that reason suitable for complaints of the eye. Fetida pills purge dense phlegmatic humor accumulated in the joints, and for that reason relieve arthritis and sciatica.

79.

Pills made from euphorbium purge the phlegmatic humors draining from the head to the nerves. It (euphorbium) is for that reason suitable for paralysis. How to compound it is learned from Avicenna in his own Antidotarium.

Cochie pills purge the humors caused by the discharge from the brain. They are for that reason suitable for epilepsy.

Paulinum ³⁰, because of its great virtue, is called the great antidote, i.e. the great composite medicine. It relieves effectively fresh cough and chronic cough caused by the flow of the phlegmatic humor from the head to the chest. For that reason it relieves chest complaints caused by phlegmatic humor. It rids the head, chest and stomach of phlegmatic humor primarily, and of melancholia secondarily. Its dosage is two drams.

80.

Take note that if in the different members with the exception of the genitals, different humors should accumulate in equal proportions, it is proper to compound different medicines in equal proportions; and should they accumulate in different proportions it is proper to compound them in different proportions so that they might contain more of one particular remedy than of the other remedy. Note also that the compound remedies are made bitter by various bitters in order that they may work more powerfully. Addition of the bitters is varied in proportion to the variation of the humors, and of the members; and for that reason the medicine which purges the phlegmatic humors of the head should be made bitter by one and one half scruples of colocynth corrected by one dram of tragacanth, or by one and one half scruples of scammony which has been corrected by mastix, or by  p.101 pasty as we have said above, or by one dram or more of esola.

81.

DICTO DE MEDICINIS EVACUANTIBUS phlegma dicendum est de medicinis evacuantibus melancolicam:: i.e. having spoken of the medicines which purge phlegmatic humor, it is meet to speak of the medicines which purge melancholia primarily; and so first of all of yera Rufini ³¹ which purges melancholia primarily. For that reason it effectively relieves those who have elephancy, morphew, or scabies caused by salt or by inflammatory phlegm.

82.

Diasene: ³² an electuary which purges phlegmatic humor accumulating in the spleen and in the heart. For that reason it specifically relieves obstructions of the spleen; relieves those who suffer from mania, and those who suffer from dejection.

Triffera sarracenica is called after the Saracens. ³³ Or it is called triffera for the reason that it is administered to him who is young. It purges melancholia of the stomach and liver. Because of that it is suitable for obstructions of the spleen and liver, and for jaundice caused by inflammatory choler.

83.

Yera logodion memphitum is so called since ιερα and sacer mean the same, i.e. blessed; since λογος and sermo mean the same, i.e. speech; and since memphitum and impedimentum mean the same, i.e. impediment; for it cures impediment of the speech whatsoever its source or origin might be. It purges specifically melancholia of the head, and is suitable for epilepsy, vertigo, hemicrania, cephalalgia, and for tremor such as is evident in those who are supposed to have a demon.

84.

Imperial cathartic, i.e. a medicine found for emperors and for other weak people. It purges the melancholic humors accumulated in the kidneys, and for that reason it relieves those having nephritis. It dispels flatus of the stomach and intestines, and is suitable, therefore, for those having ileac,  p.103 and syphilis.

85.

DICTO DE MEDICINIS EVACUANTIBUS phlegma et melancholiam dicendum est de medicinis evacuantibus coleram: i.e. having spoken of the medicines which purge phlegmatic humor, and melancholia, it is meet to speak of the medicines which purge choler such as diaprunis, and electuary of sugar of roses. Diaprunis is so called because it contains more of the fruit known as prunes than it does of any other ingredient. It purges choleric humors of the stomach and liver, and for that reason it is administered for true tertian fever, and inflammation of the liver.

86.

Electuary of sugar of roses is indicated for inflammatory gout. It purges the choleric humors, and natural choler. For that reason it relieves complaints of the joints caused by choler, also persons recovering from tertian fever. Note particularly that the dosage of these compound medicines is varied according to the larger or smaller quantity of scammony, and of other potent and virulent medicines such as hellebore, turpeth, agaric, euphorbia, colocynth, aloes, and the like which enter into their composition.

87.

Consequently, the dosage of yera pigra is three drams, and the dosage of yera Rufina two drams for the reason that it contains more of potent and virulent medicines than does yera pigra. Therefore, its dosage is smaller.

Dosage of benedicta three drams. Dosage of blancam three drams. Dosage of pill artetica (arhritis pills) two and one half drams. Dosage of pill auree (auree pills) three drams. Dosage of pill euphorbia (euphorbium pills) two drams. Dosage of theodoricon anacardium three drams.

88.

DICTO DE DOSI MEDICINARUM evacuancium phlegna dicendum est de dosis medicinarum evacuancium melancoliam: i.e. having spoken of the dosage of medicines which purge phlegmatic humor, it is meet to speak of the dosage of the medicines which purge  p.105 melancholia, and since we have stated the dosage of yera Rufini it is right y for us to state the dosage of the other medicines. Let us consider diasene first. Its dosage is one half ounce. Dosage of triffera sarracenica three drams. Dosage of theodoricon eupheriston ³⁴ two drams. Dosage of yera logodion two and one half drams. Dosage of imperial cathartic one dram.

89.

DICTO DE MEDISINE ET DE DOSI MEDICINARUM evacuanciam melancolian dicendum est de dosi medicinarum euanciantium colera rubiam: i.e. having spoken of the dosage of the medicines which purge melancholia, it is meet to speak of the dosage of the medicines which purge choler, and so first of all of diaprunes. Its dosage is one half ounce. Dosage of electuary of sugar of roses three ounces. All of these are the maximum doses for the compound medicines.

90.

Be it known unto you that it is proper to make bitter with one dram of agaric corrected by one dram of licorice the medicines which, like paulinum, purge the phlegmatic humors of the chest and of the respiratory organs. With one dram of turpeth, corrected by one dram of powdered pepper, or by myrobalan indici, or chebula in accordance with the dosages already mentioned, or by cassia fistola or by esola in accordance with their dosages, it is proper, indeed, to make bitter the medicines which purge phlegmatic humors of the stomach and of the liver.

91.

It is proper, indeed, that the laxatives which purge the hot humors be made bitter with another medicine such as myrobalani citrini, rhubarb, reuponticum or by scammony which has been corrected, or by cassia fistola or manna, or by tamarinds together with scammony. Should the liver complaint be chronic, however, let not the medicine be made bitter by scammony in dropsy ³⁵ since that destroys the liver, but let it be done with esola, or rhubarb, and let these bitters be put in  p.107 the medicines in accordance with the dosages we have already written of.

92.

The laxatives which purge the phlegmatic humors of the spleen are made bitter by two scruples of lapis lazuli that have been well washed, or by lapis Armenicus, senna, agaric, or esola according to their individual dosages.

The medicines which purge the phlegmatic humors of the kidneys, bladder, and womb are made bitter by lapis lyncis ³⁶ lapis spongie ³⁷, agaric, scammony, esola, and Jew-stone i.e. Jewish ³⁸ which has been well washed. Their quantity, two scruples. Should they be hot humors which accumulate in the same members let them (the medicines) be made bitter by scammony, rhubarb, reuponticum, or cassia fistola according to their individual dosage.

93.

Should phlegmatic humors accumulate in the joints, let the medicines be made bitter by hermodactylus, turpeth, or esola according to their individual dosage. Should they be hot humors which are accumulated in them, let the medicines be made bitter by scammony, rhubarb, reuponticum, or cassia fistola. Take note that medicines such as scammony, turpeth, agaric and the like, which are very potent and virulent, should be corrected by the aforementioned medicines before mixing them with the compounds, according to their individual dosage. Note particularly it is proper that the dosage of the bitters which enter into the composite medicines should be, as it is said in the treatise on the simples.

94.

Note particularly that just as it is proper to observe four conditions when administering the simples, i.e. strength (i.e. virtue), age, season, and habit, so in the same way it is proper to observe the same conditions when administering the composite medicines together with the four conditions which it is proper to observe when purging the evil humors. First of these conditions: the time of the paroxysm, i.e. the access. Second condition: the time of digestion.  p.109 Third condition: the season of the year. Fourth condition: the quantity of the humor which is to be evacuated. It is always proper to purge the humor at the time of the access since Haly says that should the force be strong and the matter small and light let it be purged with a gentle medicine such as cassia fistola, and manna. For that reason the ancients were accustomed on the day of the paroxysm, as is evident in quartan fever, to give a laxative powder one hour before the paroxysm, and by this means a great many were healed.

95.

The time of digestion; moreover for only when the matter is digested is it proper to administer the medicine to purge the particular humor, just as Hippocrates says, “Digesta medicare, et cetera.” For that reason Avicenna says that there are two things which assist the operation of the medicine, i.e. digestion of the matter, and openness of the passages. The season of the year also since Avicenna says that it is proper to observe it as an adjuvant to purging; because at the time when the constellation called canis major is rising such as is visible in the summer, or at the time of severe cold such as the winter, laxatives are not suitable to take. For that reason Hippocrates says; “Sub Cane et ante canem, et cetera.” The medicine is suitable, however, to administer in the spring and autumn. Yet, should purging be necessary, and the constitutional vigor (of the patient) be good, hindrance by anything is not to be considered. For that reason it is possible to cause purging in the summer and in the winter. That is properly done, however, with mild medicines such as cassia fistola, manna, and tamarinds.

96.

The fourth condition, the quantity of the humor which is to be evacuated: and Avicenna says that is twofold, i.e. the quantity according to measurement, and the quantity according to quality. Quantity according to measurement: such as one ounce, or one dram. The quantity according to quality:  p.111 i.e. the gradation of the degree.

97.

It is relative to the quantity of the measurement that Galen said in his Megategne, “Quantitas eorum quae offeruntur letteris non est determinata”: i.e. “the quantity of things administered is not determined by scholarship” i.e. by the senses; for neither the quantity of the measurement of the humor, nor the quantity of the efficacy of the cure is easily determined by the senses but according to the judgment, or opinion of the physician who is close to being exact. For that reason Haly says: “Oportet quod medicus sit bone rememoracionis, velocis solercie sane intellectus, et cetera:” i.e. it is necessary for the physician to have a good memory, ready wit, sound understanding, good eyesight, and much balance. ³⁹ Avicenna says, however, that the measure of the quantity of the amount is recognized in accordance with the measuring system of the profession, from two circumstances, i.e. from the nature of the member and the extent of the affection, and from the suitability of particular things such as class, age, habits, season, predisposition, calling, strength, and mode of administration.

98.

The quantity of the quality of the degree: for should the humor, indeed, be hot it is proper to administer for it a medicine that is contrary in quality and degree; and should the humor be cold it is proper to administer for it a hot medicine of the degree in which it is.

The fifth condition which must be observed in purging the humor: the place where it is located. Should it be at the cardiac orifice it is proper to purge it by vomiting, and should it be in the fundus of the stomach, or in the intestines it is proper to purge it with a laxative. And so on for the other places, it being proper to purge them through convenient regions.

99.

Note particularly that some of the medicines are administered as a solid substance, and  p.113 others as a liquid substance. The medicines administered as a solid substance are always in pills, or electuaries. Should they be in pills it is proper to administer them together with wine and a wafer at the beginning of the night. It is proper to sleep on them since they require a powerful heat to dissolve them, and the heat passes into the internal members at night. For that reason Avicenna says: “Cum aliquis medicinam solutiuam biberit melius est si medicina fuerit fortis ut super eam dormiat:” ⁴⁰ i.e. when a person drinks a laxative it is best for him, should the medicine be strong, to sleep on it before it operates as its efficacy is thus improved. It is best for him, should the medicine be weak, not to sleep on it, since nature would digest it. For this reason it is proper that the medicine administered as a soft substance, because of its mildness, should be administered in the morning when sleeping is finished. However, Haly says that, should the patient be feeble or weak, or should it be summer time, one should take as a draught before going to bed a medicine which is mildly laxative; that it is not proper to sleep on it after purging, and that, whatever medicine it might be, it is best not to sleep on it when the medicine begins to operate.

100.

Note particularly how Avicenna says that it is not proper to administer pills when they have become dry, when they are like stones, or when they are soft; but when they commence to dry, and when they yield before the fingers on being pressed.

The electuary: it is indeed proper to administer it at midnight between the hour for the pills and the hour for the liquid medicine, because it is easier to dissolve the electuary than the pills, and harder than the liquid medicine.

101.

Note particularly that there are four species of the liquid medicine, for there is one species called cholalogue which purges choler, another called melanagogue which purges melancholia, another called phlegmagogue which purges phlegm,  p.115 and another called emmenagogue which purges the sanguine humor.

A cholalogue is made thus: take violet blossoms, and borage blossoms, of each four ounces; prunes fifty; myrobalani citrini two and one half ounces; cassia fistola when cleaned, tamarinds, rhubarb, and manna, of each item two drams. Let the rhubarb and the myrobalan be strained.

An emmenagogue is made of the same items, with the exception of not containing the myrobalan and rhubarb; for Avicenna says the medicines which purge choler, purge sanguine humor also.

102.

A melagogue is made thus: Take thyme, epitimus ⁴¹, and two species of sticados, of each item two drams; borage blossoms, and violets, of each two ounces; Indian myrobalan, and chebuli, of each one ounce; triffera sarracenica, one half ounce; and lapis lazuli when well washed one half ounce. Let the myrobalan and lapis lazuli be well strained, or as we have already saidd give after manipulating it for five or six times.

Phlegmagogue is made thus: Take anise, maratrum, ameos, of each item one ounce; myrobalan chebuli, two ounces; and turpeth, half of one dram. It is possible, depending on the variation of the member to include benedicta, yera pigra when made mild, or other items. Let the myrobalan and the turpeth be strained, however as we have said.

103.

DICTO DE MEDICINIS LAXATIVIS dicendum est de opiatis: i.e. having spoken of the laxatives it is meet to speak of the opiates. They are called opiates because of the opium which enters into their composition. Note particularly that the opiates have three virtues, i.e. the virtue of checking the flux of the humors which run to an affected part; the virtue of strengthening the part towards which they flow; and the virtue of consuming the humors. Note particularly that there are opiates which are administered before the laxative. Of these  p.117 dyamoron ⁴² is an example; for should it be compounded with an item in which has been boiled rose, and licorice which has been cleaned, it checks the flux of the humors to the muscles of the throat. For that reason it is suitable for quinsy.

104.

Tyriacla, i.e. the theriac: ⁴³ Should it be mixed with wine in which sage is boiled, and given as a drink, it prevents poison from penetrating to the heart. For that reason it is suitable as an antidote to poison.

Athanasia ⁴⁴ : should it be compounded with extract of plantain, and administered as a drink it checks the blood and regularizes the pulse. For that reason it is suitable for haemorrhage. The dosage of this opiate is one to two drams.

Aurea Alexandrine, ⁴⁵ indeed, is one of the opiates administered after the laxatives. Let it be administered when it has been compounded with hot water. Let a gargle ⁴⁶ be made from it. It is suitable for all head affections, and for a flux of rheum to the eyes, ears, and gums. Should it be administered after another medicine, however, administer it when getting a bath. In that way it is suitable for persistent quotidian fever.

105.

Mithridate ⁴⁷ and musa enea: ⁴⁸ administer them after the medicine, and before the access, and when they have been compounded with tepid wine through which water has been put, and they will consume the humors. For that reason they are suitable, prior to the time of the access, said in the manner we have mentioned, for those who have quotidian fever. Following the medicine and prior to the time of the access, it is proper to administer rubea troches, ⁴⁹ and recuies when they have been compounded with hot water since they check the flux of the choleric humors to the location of the putrefaction, and consume the matter. For that reason they are suitable for those who have tertian fever.

106.

Should micleta ⁵⁰ along with extract of plantain, or syrup of myrtle be given to drink after the medicine, it is suitable for, and relieves miraculously hemorrhoids which are bleeding immoderately.It is excellent for dysentery and lientery.

This suffices for the doses of the medicines, et cetera.

Finit. Amen
