History of Pharmacology
• Treatments to regain the humoral balance used combinations of “drugs” consisting of various amounts of characteristics of the elements (hot,cold,wet,dry). John Gerard (1545-1612) authored an herbal compendium which catalogued the characteristics of medicinal plants with respect to the four humors. Fever (too much heat) was treated with mendicants composed of cool and wet plants.
