Origin

Arbitrary alteration of earlier capsicine, capsicin (“material extracted from cayenne pepper”), presumably to prevent confusion, from German Capsicin, from New Latin capsicum + German -in. Name introduced by John Clough Thresh (1850-1932) in “Capsaicin, the Active Principle of Capsicum Fruits”.
