“ Of the Virtues of Vitriol in Medicine: first, of it Crude, and its Colcothar. In explaining the virtues of Vitriol, I will first speak of the virtues of it Crude, and of its Colcothar. Therefore, know ye, Vitriol is a famous Purgation, in grievous and difficult Diseases of the Stomach. For it sometimes happens, that the Stomach is distempered by Meats and Drinks, and falls into a Diuturnal Disease, which continues unto death, and by depraved Meats and Drinks, it often comes to pass, that the Sick are either contracted in their Members, or die. ”

A. C. Wootton,  Chronicles of Pharmacy, Vol. 1…

“ Added to an infusion of balm, marjoram, and bugloss, it would cure headache and vertigo; with rose water, fevers; with fumitory water, itch; with fennel water it would restore decayed memory; with plantain water it was a remedy against diarrhœa; and with lettuce water it became a narcotic. “A rare fellow,” quaintly comments the doctor. Homberg’s narcotic salt of vitriol was a combination of green vitriol and borax made after a very complicated process. The Gilla Vitrioli was a purified white vitriol used as an emetic. Spiritus Vitrioli dulcis was an imitation of Hoffmann’s Anodyne. ”

“ Externally slight solutions of blue vitriol, as two or three grains to an ounce of water, applied to ulcers of the mouth, or to chancres on the glans penis, more powerfully induces them to heal than any other material.
Where the lungs or urethra are inflamed to a considerable degree, and the absorption is so great, that the mucus is already too thick, and adheres to the membrane from its viscidity, opiates and bitter vegetable and austere acids are improper; and mucilaginous diluents should be used in their stead with venesection and torpentia.
