The way of making Volatile, or Essential SALTS.
Take a sufficient quantity of any fresh succu∣lent Plant, beat it in a wooden or Stone Mortar; then pour a large quantity of clear fountain wa∣ter upon it, boil it till half is consumed, strain it hard, and boil it again to the consistence of Ho∣ney; put it into a glass vessel or glazed Pot, and set it in a cold place for eight days at least, and a Crystal Salt will grow together in the manner of Sal Gemma, which by pouring out the decocti∣on may be collected; it must be washt in its own water and dryed for use. This way is made the Salt of Wormwood, Carduus Benedictus, Mugwort, and of other bitter Herbs easily, but of others very difficultly.
