The Dose is, that 1. 2. 3. 8. 10. grains be macerated for the space of a night in wine, which is to be drank in the morning, and it worketh upward and downward. But it is not to be given to children, those that be old, and weak, but to those that be strong, and accustomed to vomiting. When at any time this infusion is taken and doth not work, as sometimes it falls out, but makes the Patient very sick, he must provoke vomiting with his finger, or else it will not work, but make those that have taken it to be sick, and debilitated even to death. We must also in the over much working of these flowers drink a draught of warm Beer, or rather of warm Water, decocted with Chervil, or Parsly, and they will work more mildly. But let not him that is able to bear the operation thereof any way hinder it, for there is the greater hope of recovering his health thereby, for they do excellently purge choler, and evacuate flegme in the Stomack, being humors that will not yield to other Catharticks; they open obstructions, resist the putrefaction of the blood, the causes of many diseases, such as are Feavers, Head-aches, _&c._ they are good for them that are Leprous, Scorbutical, Melancholical, Hypochondriacal, infected with the French-Pox, and in the beginning of the Plague. In brief, they do work gallantly, and do many things. After the taking of them, the Patient must stay in his bed or at least not go forth of his house, for to avoid the aire, or otherwise they may be mistrusted. And because of their violence they are feared, and hated, I shall in the fourth part of this Book for the sake of the sick set down such as are milder, and safer, such as shall work rather downward than upward, causing easie vomits, which also thou mayest give to children, and those that are old without danger, yet some respect being had of the disease, and age. _The flowers of Antimony diaphoretical._ The foresaid flowers if they be cast into melted Nitre, and be left a while in melting, are made fixt, so as to become Diaphoretical, and lose their Cathartical Vertue. The acid water being separated from the flowers, if it be evaporated, leaves behind the best spirit of salt, serving for the same or such like uses again. _Of the External use of the Corrosive Oyle of Antimony._
