DIGBY, guérison des playes par la poudre de sympathie, 1681

New edition containing in a second part the Dissertation on the powder of sympathy, translated in french from the Latin of Mr. Papin
Kenelm Digby (1603 – 1665) was an English courtier and diplomat, and an alchemist. Explaining everything by occult causes, fermentation, and effluvia, he thought he could cure with the “Powder of Sympathy”, a preparation of pulverized and calcined vitriol supposed to act, even at a distance, on wounds and injuries.
