CHAP. XIII. OF VOMITING.
As a vomit even in health is often necessary to persons of a bilious habit; it is likewise so in those distempers, which are occasioned by bile. Upon this account it is necessary to those, that before fevers are distressed with horrors and tremors; to all those, that labour under a cholera; and all, that are attacked with madness, and a concomitant mirth; and those also, who are oppressed with an epilepsy. But if the distemper be acute, as the cholera; if it be a fever, while there are tetani, the rougher medicines are improper, as has been observed above in the article of purging; and it is sufficient to take such a vomit, as I prescribed for people in health. But when distempers are of long standing, and stubborn, without any fever, as an epilepsy or madness, we must use even white hellebore. Which it is not proper to administer in the winter, or summer; it is best in the spring: in the autumn it does tolerably well. Whoever prescribes it, ought first to take care, that the body of his patient be moist. It is necessary to know, that every medicine of this kind, which is given by way of potion, is not always beneficial to sick people, to healthy always hurtful.
