Pepper, because of its volatile oil, acts like other substances containing volatile oils; thus externally it is at first rubefacient and counter-irritant, and subsequently it acts as an anodyne. Internally it increases the secretions of the mouth, and in the stomach it is stomachic and carminative. During its excretion it stimulates the mucous membrane of the genito-urinary tract. Piperin is believed to be a feeble antipyretic and antiperiodic.
