Those things which remedy a dry state of the bowels are treated of in the First Book sufficiently. But since a humid or loose state of the bowels may prevail in fevers, this also must be treated of; for many are cut off not by the fever itself, but by this symptom alone. In the commencement, we must not interfere with the discharge when it proceeds from corruption of the food and indigestion; but when the evacuation becomes immoderate, it must be restrained. If the discharges are of an acrid nature, that which is given should consist of good juices, and be otherwise thick, such as spoon-meats from pearl-spelt (chondrus) and ptisan. Baths are also befitting after the complaint has become concocted. But when the discharges consist of phlegm and are watery, on the other hand, the food ought to be of a more dry and heating nature, as far as the fever will permit. Of this kind, are those things which are prepared from heating condiments. But they must abstain from baths, unless otherwise required. When the digestive faculty is in an atonic state, we must give food and applications of an astringent nature; the food consisting of things in particular, to which pomegranates, apples, pears, or medlars have been added, or these fruits themselves, and thin fragrant wine of an astringent quality; and the applications are to be cataplasms made of polenta, and dates, and wormwood, roses, myrtles, and such like things. It must be considered also, to what part these cataplasms are to be applied, I mean the region of the stomach, the lower belly, or perhaps the loins. Bloody discharges are restrained and dried up by remedies containing fine flour of polenta, with frankincense, or manna mixed with wine, or oxycrate. When the watery discharge is acrid, it must be sweetened by a _lavement_ either with water alone, or the juice of ptisan, or of chondrus, or rice, or tragum, not once, but often; and afterwards there are to be added dried roses, or myrtles, and sometimes galls; and an egg with rose oil, and a thin astringent wine, or the decoction of roses, may be injected or applied to the anus, which will blunt the desire of going to stool. But when the calls are frequent, a clew formed of warm threads may be applied to the anus. * * * * * COMMENTARY. Galen forbids venesection when the fever is complicated with diarrhœa.
