Andrew Duncan, Observations on the Operation and Use of Mercury in the Venereal Disease (1772)
“ Many of those mercurials, which have 18not such an influence upon the stomach as to produce vomiting, upon entering the intestinal tube, act as purgatives. This effect of mercurials is, among other preparations, particularly remarkable on the use of the Coralline mercury, Prince’s powder, or calomel.Mercurials, which fail in producing either purgative or emetic effects, frequently act as diaphoretics. Diaphoresis, or even a profuse sweat, is often the consequence of many of the mercurials already mentioned. ”
