Of Vitriol
Nature generates a Salt, called Vitriol. This is a peculiar kind separated from all other Salts, possessing also Virtues different from them. Its Virtues are so many, and so famous, as of right they ought to be described in this Book. For, a perfect Cure of the Jaundice is latent in Vitriol, also of the Gravel and Stone in the Reins or Bladder, of all Feavers, Worms, Falling-sickness, &c. And in Constipations of the Body, it is a famous Deopilative: In the mean while of other Virtues in this Chapter to be mentioned, I here am silent. The Description of this is to be directed both to Medicine and Alchymy. For in Medicine, it is an excellent Remedy; in Alchymy it is profitable for many other things. But the Art consists in the Preparation of Vitriol for Medicine and Alchymy. For Vitriol crude, is no such thing. It is like Wood, of which all things may be made. It is profitable for Medicine of the Body; it profits also in Chirurgery, or External Diseases, as the Psora, Tetter, Hereditary Leprosie, and others; where all other Remedies are ineffectual, and as it were dead to the Disease. Vitriol assaults Diseases of this kind powerfully, and cures them fundamentally. Therefore the true Preparation of Vitriol is in a special manner to be known by Physicians. For its Virtues when crude are other, than when dissolved; and other when calcined, than when converted into a green, red, or white clear Oyl. This is the condition of it, that as often as it is reduced into another form, so often it is made a peculiar Arcanum.
This confounds all Apothecaries, and Writers, both Italians and Germans. For this part is such, as it alone per se can fill a fourth part of all their Shops, and cure Diseases proportionally. This being present, there is no need of so many Boxes, Pots, Glasses, &c. set all of a row, and disposed in order in Shops. It concerns a Physician, not to take care for so many Boxes, and Beyond-Sea Medicines, but to be circumspect, provident, and wise as a Virgin; since in such numbers of Vessels adulterate Remedies are for the most part contained. If he use the aforesaid circumspection, at his own doors he will find more choice Remedies, against all Diseases, than India, Egypt, Barbary, or Greece can afford.
Let every Physician follow this Basis, for it is now known even to plain Country-men, that meer Frauds are contained in those Boxes: Which, as they are for the most part of Wood, so are they that use them Wooden Doctors and Apothecaries: But like with like do very well agree.
