CHAP. IX. THE CURE OF SLOW FEVERS.
Sometimes too we find slow fevers continuing without remission, and no room left either for food or any remedy. In this case it ought to be the care of the physician to change the distemper: for perhaps it may become more easy to cure. For this reason the body of the patient is often to be gently rubbed with cold water with oil infused, because sometimes it thus happens, that a shuddering arises, which may be some beginning of a new commotion; after that, when the body has grown hotter, a remission may follow too. In these cases friction with oil and salt seems to be a useful method.
But if coldness of the extremities, and numbness, and restless changes of postures continue long, it is not amiss, even during the fever, to give three or four cyathi of mulse, or well diluted wine together with food. For the fever is often encreased by it; and a greater heat arising at the same time both removes the former disorders, and affords hope of a remission, and from that of a cure.
And indeed the method of cure is not new, to make use of contrary medicines, by which at this time some recover patients committed to their charge, who were long under the care of more cautious physicians. For even amongst the ancients before Herophilus and Erasistratus, but after Hippocrates, was one Petron, who, as soon as he was called to a person in a fever, laid a great many cloaths upon him, that he might at once excite a great heat and thirst. After that, when the fever began to be a little abated, he gave cold water to drink; and if it once raised a sweat, he pronounced the patient to be out of danger: if it had not procured that discharge, he gave still more cold water, and then obliged him to vomit. If by either method he freed the person from the fever, he immediately gave him roast pork and wine. If it did not give way to these methods, he boiled water with salt, and obliged him to drink it, that by vomiting he might cleanse his belly(9).
And these particulars made up his whole practice. Which was not less acceptable to those, whom the successors of Hippocrates had not recovered, than it is to those in this age, who have been long unsuccessfully treated by the followers of Herophilus or Erasistratus. Nor is this kind of medicine upon this account not to be esteemed rash; because if it has been pursued from the beginning, it kills more, than it cures. But since the same things cannot agree with every body, those commonly, who are not restored by a rational method, are relieved by temerity; and for that reason physicians of that class manage another’s patients better than their own. But it is a practice not unbecoming even the man of circumspection, at times both to change a distemper, and to increase one, and to inflame fevers; because where the disorder, that is present, does not admit of a cure, another may, which is to succeed in its place.
