Theses de sudore

The same must be most diligently observed in time of plague during the administration of theriac or other bezoar-based remedies. Nor do we approve of the method of those who, having administered some adipharmacon a remedy for poison, immediately command sweats in the infected person without any consideration for the movements of nature. For this reason, they leave the patient, who is almost suffocated by a stack of blankets and bedding and badly distressed, with the greatest loss of strength.

He whose liver or spleen has withered, or hardened through great obstruction or scirrhus, as in ascites, jaundice, or cachexia, cannot be induced to sweat by any power, not even through fevers, even if the whole body is teeming with much humor; not because the first source of sweats is in the precordia (as Fernel believes in Pathology book 4, chapter 10), but because of the coldness of those viscera, the density of the cutaneous passages, the crudity, and the weak heat of the venous type, which is not capable of cooking the thick humors. Unless perhaps, in imitation of certain ancients, he called those parts the precordia in which the liver, spleen, pancreas, mesentery, and stomach are contained.

Warm sweats are produced by vigorous, cooking heat (Aristotle, Problems 31, section 24), as well as by the warming of the parts through which the ichor passes, and by boiling humor, as in bilious fevers.

XXXI.

Cold sweats, however, are produced by the extinction of the heat of the parts (Aphorisms 4.37), as in most vehement colic, cardiac syncope, fainting, suffocation of the uterus, and pestilential fevers; likewise by the companionship of an abundance of cold humor mixed with the serum, as in those who eat cucumbers, melons, and the like.

XXXII.

Sweats acquire saltiness from heat blowing upon the blood mass. Aristotle proposes an example of this to us in Meteorology 2, regarding the saltiness of the sea. And Galen in Epidemics book 6, regarding the boiling of spring water; we pass over in silence his own place in On the Differences of Fevers book 2, chapter 6, where he wishes all serous humidity to be salty.

XXXIII.

Bitter sweats arise both from prolonged cooking (Galen, On the Faculties of Nourishment book 3, chapter 32) and from the admixture of some bitter juice, such as bile.
