Of the Vegetable Tincture, or the Process called the Lesser Circulation.
VERY few of the true philosophers have touched upon this subject, for it seemed
trifling in respect to the great work, as the process in metals is generally termed; but there is a modern publication in English, a small thin duodecimo, without any author's name, having for its title "Aphorisms, seu Circulus majus et Circulus minus," wherein the whole process is plainly laid down.
This book is written by an undoubted master in the art; and no treatise, ancient or modern, is so explicit in the directions for conducting the great work. The directions are very short, but much to the purpose, provided the reader has an idea what part of the work is alluded to. The author, agreeable to his title, delivers his doctrine by way of aphorisms. But to return from this digression.
We proposed in this chapter to lay open the vegetable process, as a clue to the more important work in the mineral kingdom. A certain person, who is now living, and advertises balsam of honey, tincture of sage, etc., has turned his studies this way; and from his great abilities as a professed
physician and botanist, has convinced all unprejudiced persons that noble tinctures may be extracted from vegetables. We hope this gentleman will not despise our free communication, both to him and the public, if we show the insufficiency of his method, though it is ingenious, while we establish the rationale of ours on the never-failing ground of truth and philosophy.
He observes, with a precision which can only result from numerous trials, that different herbs impart their tinctures in such proportions of alcohol as he has found out. It is allowed that the volatile spirit and balsamic sulphur are thus extracted; but there are the essential, or fixed, salt and sulphur of the herb yet left in the process. These require another management to extract, which he is either ignorant of, or is so disingenuous as to conceal from the public; but that so noble a secret may lie open to all for a general advantage, here follows a plain account of the vegetable work.
Take any herb which is potent in medicine, and either extract the tincture with spirit of wine, or distil in the common way; reserve the distilled water, or tincture, when separated from the fæces, for use. Then take the feces, or Caput Mortuum, and calcine it to a calx. Grind this to powder. That done, take the water, or tincture, and mix them together; distil again, and calcine, forcing the moisture over by a retort, in a wary process, calcining and cohobating the spirit on the salt till it attains a perfect whiteness and oily nature, like the finest alkali, commonly called Flemish. As your salt requires it in the process, have in readiness more of the extracted tincture, or distilled spirit, that you may not work it, viz., the salt, too dry; and yet proceed cautiously, not adding too much of the moisture, so that the dealbation, or whitening, may keep visibly heightening at every repetition of the process. Frequent experiments may enable you to push it on to a redness, but
a fine yellow is the best of all; for the process tends, in its perfection at this period, to a state of dryness, and must be managed with a strong fire. By following these directions, you have here the two tinctures in the Vegetable Kingdom, answering to the white and red tinctures in the mineral.
