In every cough it does service to take journies, long voyages, and to live near the sea, and to swim. The diet must be sometimes soft, as mallows and nettles; sometimes acrid, as milk boiled with garlick; gruels, to which laser has been added, or such as have had leeks boiled in them, till they have lost all their verdure. A sorbile egg also with an addition of sulphur may be supped; for drink warm water may be taken first, then alternately, some days water, and other days wine. [Sidenote: _Of a spitting of blood._] A spitting of blood may strike a greater terror. But that sometimes is less, and sometimes more dangerous. For it issues sometimes from the gums, sometimes from the mouth; and indeed from the latter very plentifully at times, but without a cough, without an ulcer, or any distemper of the gums, and without expectorating any thing; but breaks out from the mouth in the same manner, as from the nose. And sometimes pure blood is discharged, at other times something like water, in which fresh meat has been washed. Sometimes it comes from the upper part of the fauces, which may happen by means of an exulceration in that part; or when it is not ulcerated, either from the mouth of some vein opened, or tubercles rising there, and discharging the blood. When this is the case, neither meat nor drink do harm, nor is any thing expectorated, as from an ulcer. But sometimes, when the throat and wind-pipe are ulcerated, a frequent cough forces out blood too. Neither is it uncommon for it to come either from the lungs, or the breast, or the side, or the liver. Women, whose menses are suppressed, often have these spittings. And medical writers say, that blood is discharged either by the erosion, or the rupture of some part, or the dilatation of the mouth of some vein. The first they call diabrosis[CQ], the second rhegmochasmus[CR], the third anastomosis[CS]. The last does least hurt; the first is most dangerous. And it often happens, that the blood is followed by pus. [CQ] διάβρωσις. [CR] ῥηγμοχασμὸς. [CS] ἀναστόμωσις.
