Anonymous ~ Tractatus de Lapide
"In the use of this Medicine, many great Philosophers themselves, after they obtained this wonderful blessing, desiring to have perfect Health, have been so bold as to take a certain quantity of it, some no more than a quarter of a grain, some less, some more, but all that did so with it, instead of Health, took Death itself; for there is no small skill to it for Medicine, though every fool think if he had it, he could cure all diseases, and himself too, and set the Elements at unity, which few men have known, neither is there but one way to it with safety; if this be not known, more hurt than good may be received by it. For the method of Health, it is thus: Take the quantity of four grains, I do not mean the grains of Wheat, or Barley grains or corns, but four grains of Gold weight, and dissolve them in a pint of white or Rhenish wine, but in no hot wine, as Sack, &c. put it into a great clean Glass, and instantly it will colour all the Wine almost as red as it self was, which is the highest red in the World: let it stand so, close covered from dust, four days, for in respect it is an Oylie substance, it will not presently dissolve in Wine; then add to this pint more by degrees, until it be not so red, stirring it with a clean stick of wood, not of metal, nor Glass, and so continue the pouring on of fresh Wine, until it be just of the colour of gold, which is a shining yellow. Beware that there be no redness in it; for so long as there is any redness in it, it is not sufficiently dilated, but will fire the Body, and exhaust the Spirits: neither is it sufficiently brought to yellow, until the Wine have round about the sides a ring like Hair, of a whitish film, which will shew itself plain when it is well dissolved, if it stand but four hours quiet. As soon as you see this whitish film, then let it run through a clean linen Cloth, or Paper, so the white film will stay behind and look like a pearl on the paper: and all the rest will be yellow like Gold. This is the token of truth, that you cannot wrong yourself by this Liquor; and without this token, it will be either too weak, or so strong that it will fire the Body. Know this to be a rare Secret. Of this Golden Water, let the party (of what disease soever he be sick of) take each morning a good large spoonful, and it shall expel the disease whatsoever it be, by a gentle sweat; for it purgeth not, nor vomiteth, nor sweateth so much as to make faint, but to corroborate: I say, it strengthens the party; and if the disease be of many years continuance, or a Chronical disease, it will then be perhaps twelve days, otherwise but twenty four hours, or two or three days at most. Thus it must be used for all diseases internal: But for all external diseases, as Ulcers, Scabs, Botches, Scores, Fistulas,
Noli me tangere's, &c, the place must be anointed with the Oyl of the Stone it self, not dilated in wine; and after this manner it must be done nine or ten days, and be it whatsoever it will, it will cure all outward and inward diseases. And more than this, whosoever carries this Stone about him, no evil Spirit can or will stay in the place; nay bringing or giving it to a party possessed, it drives away and expels the evil Spirits: for it is a Quintessence, and there is no corruptible thing in it; and where the Elements are not corrupt, no Devil can stay or abide, for he is the corruption of the Elements. This Medicine taken nine days as aforesaid, and the Temples of the Head anointed with the Oyl of the Stone each day in the Morning, it will make a man as light as if he could fly, and his Body so aerial it is not to be credited, but by him who hath experienced it. These most admirable qualities it hath, perfect health it giveth, till God calls for the Soul; and perfect knowledge it giveth (if the truth be known

but even this part hath been known but to a few that have made it, for it is a Divine, and as it were an Angelical Medicine. The white is not to be used for any disease but Madness, in the same proportion, and way or preparation that the red Stone was..."
