The general way of making extracts.
They may be prepared of any thing almost that belongs to the Materia Medica, or of any Me∣dicine whether it be simple, as Herbs, Flowers, Seeds, and the like; or compound, as Species, Pills, and the like; which is wont to communi∣cate a Tincture to the Menstruum wherein it is infused; wherefore, take as much as you please of any thing of the Materia Medica, cut it, bruise it or otherwise prepare it as is necessary for the infusion; pour upon it a sufficient quantity of Spirit of Wine, or any distilled Water, that is agreeable to the Phy∣ficians intention; let them remain in infusion in a Bath, or some other gentle heat two days, more or less, as the density or the tenuity of the matter requires, until the liquor has a sufficient Tincture; then separate the Tincture by inclination, put in more liquor as before, and after infusion separate it as before; mix the Tinctures, and fi••ter them through paper, and then evaporate the moisture, till the matter at the bottom of the vessel, be re∣duced to the consistence of Honey. Keep it for use; whereunto may be added two scruples, or half a dram of some proper Salt to every ounce of the extract, to keep it from drying.
