Theses de sudore

VII.
The matter of sweat, according to Hippocrates, Diocles, Aristotle, Theophrastus, Plato, Galen, Avicenna, and Eustathius, is one and the same: the ichor of the veins and arteries.

VIII.
And therefore, we judge that many err who, following Galen (On the Causes of Symptoms book 3, chapter 2) and Avicenna (book 1, Fen 1, doctrine 5, chapter 1), take refuge in diaphoretics sweat-inducing agents to effect a soterian preservation/salvation of either the symphyton hygrotetos innate moisture or the solid substance of the parts.

IX.
The efficient cause of sweat is heat, which attenuates the matter and expels the attenuated matter through suitable passages.

Hence we see that those are prone to sweating who possess a liver and spleen that are warmer and moister.

XI.
And although cold may also express sweat, it does not do so proto kai kath’ hauto primarily and of itself.

XII.
It accomplishes this either through allotriosin alienation/displacement of heat. Thus, cold water, generously drunk by one who is inflamed either by exercise or by the heat of the sun, soon moves sweats on all sides. The same happens when a few drops of vinegar, especially sharp vinegar, are tasted.

XIII.
Or, it happens when parts tempered by coldness—which were languishing from excessive heat—having regained their strength, expel through sweat what they previously dared not attack while languishing. Thus, in a case of causus a burning/bilious fever (provided there is no opposing great inflammation of the viscera or tumor of the spleen), a generous drink of very cold water, either pure or prepared with endive, sow-thistle, chicory, barley, and syrup of vinegar or vinegar of citron, is exhibited,
