Of Medicine, in Eight Books

by Aulus Cornelius Celsus

Nevertheless, if a person examine more curiously into these different species (which is not here the province of a physician) he will easily understand that the effects of them all proceed from one cause; that is, the carrying off of something. For a part will be bound, when that thing is taken away, the intervention of which had caused it to be lax; and another is softened by removing that, which occasioned the hardness; and the body is filled, not by the friction itself, but by that food, which afterwards makes its way to the skin, relaxed by a kind of digestion[(26)]. And the degree of it is the cause of these effects so widely different.

But there is a great deal of difference betwixt unction, and friction. For it is necessary for the body to be anointed, and gently rubbed even in acute and recent distempers; but this must be done in the time of their remission, and before taking food. But to make use of long friction is not proper, either in acute or increasing disorders; except when the intention of it is to procure sleep in phrenitic patients. This remedy is very agreeable to inveterate distempers, and where they have abated somewhat of their first violence. I am not ignorant that some maintain, that every remedy is necessary for distempers, while they are increasing, not when they are going off spontaneously. But this is not just; for a distemper, though it would come to a period of itself, may notwithstanding be sooner terminated by the application of remedies. The use of which is necessary upon a double account, both that the health may be restored as soon as possible; and that the disorder, which remains, be not irritated again by any slight cause: for a distemper may be less violent, than it has been, and yet not entirely removed; but there may be some remains of it, which the use of remedies may dissipate.

But though friction may be used in the decline of an illness, yet it is never to be practised in the increase of a fever; but if possible, when the body is entirely free of it; if that can’t be done, at least when there is a remission. It ought also to be performed sometimes over the whole body, as when we would have an infirm person take on flesh; sometimes in particular parts, either because the weakness of that part itself, or of some other, requires it. For both inveterate pains of the head are mitigated by the friction of it (yet not during their violence) and any paralytic limb is strengthened by rubbing it: but much more commonly, when one part is pained, a different one is to be rubbed; and particularly, when we want to make a derivation from the upper or middle parts of the body; and with this intention we rub the extremities. And these people are not to be regarded, who prescribe to a certain number, how often a person is to be rubbed: for that is to be estimated from his strength. Thus if one is very weak, fifty times may be sufficient: if of a more robust habit, it may be done two hundred times. And then in different proportions betwixt these two according to the strength. Whence it also happens, that the motion of the hands in friction must be less frequent in a woman than a man; less frequent in a boy or an old man, than a young man. Lastly, if particular parts are rubbed, they require much and strong friction. For the whole body cannot be quickly weakened by a part, and there is a necessity for dissipating as much of the matter as we can, whether the intention be to relieve the part we brush, or another by means of it. But where a weakness of the whole body requires this treatment all over, it ought to be shorter and more mild; so as only to soften the surface of the skin, to render it more apt to receive new matter from fresh nourishment. A patient is known to be in a bad situation, when the surface of his body is cold, and the internal part is hot with a concomitant thirst, as I observed above. But even in this case friction is the only remedy, which, if it have brought out the heat, may make way for the use of some medicine.

CHAP. XV. OF GESTATION.

Gestation is most proper for chronic distempers, and those that are already upon the decline. And it is useful both to those, who are quite free of a fever, but yet are not able to exercise themselves; and those, that have the slow relicks of distempers, which are not otherwise expelled. Asclepiades said, that gestation was to be used even in a recent and violent, and especially an ardent fever, in order to discuss it. But that is dangerous; and the violence of such a distemper is sustained better by remaining quiet. Yet if any person will make trial of it, he may do it under these circumstances, if his tongue is not rough, if there be no tumour, no hardness, no pain in his bowels, nor head, nor præcordia. And gestation ought never to be used at all in a body that is pained, whether in the whole, or in any part, unless the pain be in the nerves alone; and never in the increase of a fever, but upon its remission.

There are many kinds of gestation: in the use of which the strength and circumstances of the patient are to be considered; that they may neither dissipate too much a weak man, nor be out of the reach of one of small fortune. The most mild kind of gestation is in a ship, either in a port, or a river; or in a litter, or a chair; more brisk in a chariot; more violent in a ship on the ocean. And each of them may be rendered both more sharp, and more mild. If none of them can be done, the bed must be suspended and moved to and fro. If even that can’t be accomplished, at least a prop is to be put under one foot[(27)] of the bed, and thus the bed moved back and forward by the hand. And indeed the mild kinds of exercise agree with the weakest; the stronger with those, who have been for several days free from the fever; or those, who feel the beginnings of severe distempers, but are yet without a fever (which is the case in a consumption, and indispositions of the stomach, and a dropsical disorder, and sometimes in a jaundice) or when some distempers, such as an epilepsy or madness, continue, though for a considerable time, without any concomitant fever. In which disorders, these kinds of exercises also are necessary, which were mentioned in that place, where we prescribed rules for the conduct of sound, but weakly men.

CHAP. XVI. OF ABSTINENCE.

There are two kinds of abstinence. One, when the patient takes no food at all: the other, when he takes only what is proper. The beginnings of diseases call for fasting and thirst: after that in the distempers themselves moderation is required, so that nothing but what is proper be taken, and not too much of that; for it is not fit after fasting, to enter immediately upon a full diet. And if this be hurtful even to sound bodies, that have been under the necessity of wanting food for some time, how much more is it so to a weak, not to say a diseased one? And there is nothing which more relieves an indisposed person, than a seasonable abstinence. Intemperate men amongst us chuse for themselves the seasons of eating, and leave the quantity of their food to the physicians. Others again compliment the physicians with the times, but reserve the quantity to their own determination. Those fancy themselves to behave very genteelly, who leave every thing else to the judgment of the physicians, but insist upon the liberty of chusing the kind of their food; as if the question was, what the physician has a right to do, not what may be salutary to the patient; who is greatly hurt as often as he transgresses either in the time, measure, or quality of his food.

CHAP. XVII. OF SWEATING.

A sweat is procured in two ways; either by a dry heat, or a bath. A dry heat is raised by hot sand, the laconicum, and clibanum[(28)], and some natural sweating places, where a hot vapour exhaling out of the earth is inclosed by a building, as there is at Baiæ amongst the myrtle groves. Besides these, it is solicited by the sun and exercise. These kinds are useful, wherever an internal humour offends, and is to be dissipated. Also some diseases of the nerves are best cured by this method. And the others may be proper for weak people: the heat of the sun and exercise agree only with the more robust; when they are falling into a disorder, or even during the time of distempers not violent, provided they be free of a fever. But care must be taken, that none of these be attempted either in a fever[(29)], or in the time of crudity.
