De Medicina

10 To let blood by incising a vein is no novelty; what is novel is that there should be scarcely any malady in which blood may not be let. Again, to let blood in young women who are not pregnant is an old practice; but it is not an old practice for the same to be tried in children and in the elderly and also in pregnant women: for indeed the ancients were of opinion that the first and last years could not sustain this kind of treatment, and they were persuaded that a pregnant woman, so treated, would abort. Practice subsequently showed indeed that in these matters there is no unvarying rule, and that other observations are rather to be made, to which the consideration of the practitioner ought to be directed. For

it matters not what is the age, nor whether there is pregnancy, but what may be the patient's strength. So, then, if a youth is weakly, or a woman, although not pregnant, has little strength, it is bad to let blood; for any remaining strength dies out if it is thus stripped away. But a strong child, or a robust old man, or a pregnant woman in good health, may be so treated with safety. It is mostly, however, in such cases that an inexperienced practitioner can be deceived, because at the above ages there is usually a less degree of strength; and a pregnant woman has need also, after the blood-letting, of forces to sustain, not merely herself, but also her unborn child. Not that we should be in a hurry to do anything that demands anxious attention and care; for in that very point lies the art of medicine, which does not count years, or regard only the pregnancy, but calculates the strength of the patient, and infers from that whether possibly or no there is a superfluity, enough to sustain either a child or an old man or simultaneously two beings within one woman. There is a difference between a strong and an obese body, between a thin and an infirm one: thinner bodies have more blood, those of fuller habit more flesh. The more easily, therefore, do the former sustain this sort of depletion; and the more quickly is he who is over-fat distressed by it; hence it is that the body's strength may be estimated better by its blood-vessels than by its actual appearance. And the foregoing are not the sole considerations, but there is also the kind of disease, whether a superabundance or a deficiency of bodily material has done the harm, whether the body is corrupted or sound. For if the material of the body is either deficient, or is sound, blood-letting in unsuitable; but if the harm is its copiousness, or the material has become corrupted, there is no better remedy. Therefore severe fever, when the bodily surface is reddened, and the blood-vessels full and swollen, requires withdrawal of blood; so too diseases of the viscera, also paralysis and rigor and spasm of sinews, in fact whatever strangulates the throat by causing difficulty of breathing, whatever suppresses the voice suddenly, whenever there is intolerable pain, and whenever there is from any cause rupture and contusion of internal organs; so also a bad habit of body and all acute diseases, provided, as I have stated above, they are doing harm, not by weakness, but by overloading. But it may happen that some disease demands blood-letting, although the body seems scarcely able to bear it; if, however, there appears to be no other remedy, and if the patient is likely to die unless he be helped even at some risk — that being the position, it is the part of a good practitioner to show that without the withdrawal of blood there is no hope, and to confess how much fear there may be in that step, and then at length, if the attempt is demanded, to let blood. In such a case there should be no hesitation about it; for it is better to try a double-edged remedy than none at all; and in particular it should be done: when there are paralyses; when a man becomes speechless suddenly; when angina causes choking; when the preceding paroxysm of a fever has been almost fatal, and it is very probable that a like paroxysm is about to set in which it seems impossible for the patient's strength to sustain. Further although it is least proper to let blood whilst food is undigested, yet that is not an invariable precept; for the case will not always wait for digestion. Thus if a man falls from a height, if there is contusion, or something else happening suddenly has caused vomiting of blood, although food may have been taken but a short while before, yet at once the bodily material should be depleted, lest, if it forms a congestion, it should harm the body; and the same rule will hold good also in other sudden accidents which cause suffocation. But if the character of the affection permits, it should be done then only when there remains no suspicion of undigested food; and therefore the second or third day of the illness may seem the most fitting for the procedure. But whilst there is sometimes a necessity for blood-letting even on the first day, it is never of service after the fourth day, for within that interval the material itself has both been sucked up and corrupted the body, so that then depletion can make it weak but cannot make it sound. But if there is the oppression of a vehement fever, to let blood during the actual paroxysm is to cut the man's throat; the remission is therefore to be awaited: if the fever does not decrease, but merely stops increasing, and there is no hope of remission, then also the opportunity, bad as it is, as it is the only one, should not be missed. When the measure is necessary it should generally be divided between two days; on the first it is better to relieve, and later to deplete the patient, rather than perchance to precipitate his end by dissipating his strength all at once. But if this answers in the case of pus, or of the water in dropsy, all the more necessarily should it answer in the letting out of blood. If the cause affects the body as a whole, blood should be let from the arm; if some part, then actually from that part, or at any rate from a spot as near as may be, for it is not possible to let blood from everywhere, but only from the temples, arms and near the ankles. Nor am I ignorant that some say blood should be let from a place the furthest away from the damaged part, for that thus the course of the material of the disease is diverted, but that otherwise it is drawn into the very part which is damaged. Yet this is erroneous, for blood-letting draws blood out of the nearest place first, and thereupon blood from more distant parts follows so long as the letting out of blood is continued; when put a stop to, no more blood comes to the part diseased, because it is no longer drawn to the opened vein. Practice itself, however, seems to have taught that for a broken head blood should be let preferably from the arm; when the pain is situated in one upper limb, then from the arm opposite; I believe because, if anything goes wrong, those parts are more liable to take harm which are already in a bad state. Blood is also at times diverted when, having burst out at one place, it is let out at another. For bleeding from a place where it is not desired ceases after something is applied to stop it there, when the blood is given another exit. Now blood-letting, whilst it may be very speedily done by one practised in it, yet for one without experience is very difficult, for to the vein is joined an artery, and to both sinews. Hence should the scalpel strike a sinew, spasm follows, and this makes a cruel end to the patient. Again, when an artery is cut into, it neither coalesces nor heals; it even sometimes happens that a violent outburst of blood results. As to the actual vein, when completely divided by a forceful cut, its two ends are pressed together, and do not let out the blood. Yet if the scalpel is entered timidly, it lacerates the skin but does not enter the vein; at times, indeed, the vein is concealed and not readily found. Thus many things make difficult to one who is unskilled what to one experienced is very easy. The vein ought to be cut half through. As the blood streams out its colour and character should be noted. For when the blood is thick and black, it is vitiated, and therefore shed with advantage, if red and translucent it is sound, and that blood-letting, so far from being beneficial, is even harmful; and the blood should be stopped at once. But this cannot happen under that practitioner who knows from what sort of body blood should be let. It more often happens that the flow of blood continues as black as on the first day; although this be so, nevertheless, if enough has flowed out, blood-letting should be stopped, and always an end should be put to it before the patient faints, and the arm should be bandaged after superimposing a pad squeezed out of cold water, and the next day the vein is to be flicked open by the tip of the middle finger so that, its recent coalescence being undone, it may again let out blood. Whether it be on the first or on the second day that the blood, which has at first flowed out thick and black, begins to become red and translucent, a sufficient quantity has been withdrawn, and the rest of the blood is pure; and so at once the arm should be bandaged and kept so until the little scar is strong, and this, in a vein, becomes firm very quickly.

11 Now there are two kinds of cups, one made of bronze, the other of horn. The bronze cup is open at one end, closed at the other; the horn one, likewise

at one end open, has at the other a small hole. Into the bronze cup is put burning lint, and in this state the mouth is applied and pressed to the body until it adheres. The horn cup is applied as it is to the body, and when the air is withdrawn by the mouth through the small hole at the end, and after the hole has been closed by applying wax over it, the horn cup likewise adheres. Either form of cup may be made, not only of the above materials, but also of anything else suitable; when others are lacking, a small drinking-cup or porridge bowl with a narrowish mouth may be adapted conveniently for the purpose. If the skin upon which the cup is to be stuck is cut beforehand with a scalpel, the cup extracts blood; when the skin is intact, wind. Therefore when it is some matter inside which is doing the harm, the former method of cupping should be employed, when it is flatulency, then the latter. Now the use of a cup is the rule for a disease, not of the body as a whole, but of some part, the sucking out of which suffices for the re-establishment of health. And this same fact is a proof that with a scalpel, when a part is being relieved, blood must be let from that very part where the injury already exists; since unless it be to divert haemorrhage in that direction, nobody applies a cup to a part distant from the disease, but to that which is actually affected and has to be relieved. Further there may be need for cupping in chronic maladies, although already of somewhat long duration, if there is corrupted material or an unhealthy condition of wind; in certain acute cases also, if the body ought to be depleted and at the same time the patient's strength does not admit of cutting a vein; and cupping, as it is a less severe remedy, so it is a safer one; nor is it ever dangerous, even if adopted in the midst of the attack of a fever, or even with food undigested. Therefore, when blood-letting is needed, if cutting a vein is an instant danger, or if the mischief is still localised, recourse is to be had rather to cupping, not forgetting that whilst we recognize the absence of danger, its efficacy is thus the less, and it is impossible to remedy a severe malady unless by a remedy likewise severe.

12 Now purging was promoted by the ancients in almost all diseases by various medicaments, and by frequent clysters; they administered either black hellebore root, or polypody fern root, or the copper scales which the Greeks call lepida chalkou, or the milky juice of seaside spurge, of which one drop on bread purges freely, or milk, whether from an ass or cow, or goat, to which a little salt was added, which they boiled, and having removed the solidified skin, they obliged their patients to drink the whey-like remainder. But medicaments generally irritate the stomach; a motion when excessively liquid, or a clyster often repeated, weakens the patient. Never, therefore, in illness is a medicament which causes such a motion rightly given, unless when that malady is without fever, as when black hellebore root is given either to those with black bile and to those suffering from insanity with melancholy, or to those who have their sinews in some part paralysed. But in the presence of fevers, it suffices for the purpose of a purge to take such food and drink as both nourish and at the same time soften the belly; and there are sorts of illness in which purgation by milk is suitable.

Still, for the most part the bowel preferably is to be clystered; the practice was limited by Asclepiades

though still kept, but I see that in our time it is usually neglected. But the limitation which he seems to have adopted is most fitting: that this remedy should not be tried often, and yet we should not omit to use it once, or at most twice: if the head is heavy; if the eyes are dim; if the disease is in the larger intestine, which the Greeks call colon; if there are pains in the lower belly or in the hips; if bilious fluid collects in the stomach, or even phlegm or other water-like humor forms there; if wind is passed with undue difficulty; if there is no spontaneous motion, and especially if the faeces remain inside although close to the anus, or if the patient who fails to pass anything perceives a foul odour in his breath, or if the motions have become corrupted; or if abstinence does not at once get rid of the fever; or if the patient's strength does not allow of blood-letting when it is needed, or the time for that measure has passed; or if previous to the malady the patient has been drinking freely; or if a patient who has been purged repeatedly, whether that has been intentional or casual, has suddenly a suppression of motions. However, the following rules are to be observed: that the clyster is not to be administered before the third day, nor whilst there is any undigested food; nor in a case of weakness due to exhaustion by a long illness; nor to a patient who has daily a sufficient motion, nor to one whose stools are liquid; nor during the acme of the paroxysm of a fever, for what is then injected is retained in the bowel and mounting up into the head brings about a much graver danger. On the day too before the clyster the patient ought to fast, in order to fit himself for such a treatment, and on the actual day, some hours beforehand, he should drink warm water to moisten his upper parts; there should then be introduced into the bowel simply water when we are content with a gentle remedy, or hydromel as one a little stronger; or as a soothing enema a decoction of fenugreek, or of pearl barley, or of mallow, or as an astringent clyster a decoction of vervains, but a drastic one is sea-water or ordinary water with salt added; and the better in both instances for boiling. A clyster is made more drastic by the addition of olive oil, or soda, or honey: the more drastic the clyster, the more it extracts, but the less easily it is borne. The fluid injected should be neither cold nor hot, lest either way it should do harm. Following upon the injection the patient ought to keep in bed as long as he can, and not give way to his first desire to defaecate; then go to stool only when he must. In this way generally when the material is extracted, and the upper parts relieved, the disease itself is mollified. But when the patient has become exhausted owing to forced calls to stool, he ought for a while to keep quiet; and lest his strength fail, he should certainly take food that day, but whether it should be abundant or scanty, should be regulated according to the strength of the paroxysm anticipated, or the absence of such apprehension.

13 Again, a vomit, as it is often quite a necessity for one who in health is bilious, so is it also in those diseases which bile has occasioned. It is the more necessary, therefore, for all who are troubled by shivering and trembling before fevers, for all suffering from cholera, even for all suffering from insanity accompanied by a kind of hilarity, and also for those afflicted by epilepsy. But if the disease is an acute one,

as in the case of cholera, if there is fever, during the shivering fits, then the sharper medicaments are out of place, as mentioned above in relation to purgations, and for the purpose of a vomit it is sufficient to take the emetics which I have prescribed to be taken by those in health. But when there are chronic and violent diseases without fever, such as epilepsy and insanity, white hellebore root should also be used. But it is not right to give it either in winter or in summer; the spring is the best time, and autumn tolerably good. Whoever is going to administer it ought to take care beforehand that the body of the prospective recipient is rendered more humid. This should be recognized, that all such medicaments given as a drink do not always benefit the sick, and are always harmful to those in health.
