Capsaicin (8-methyl-N-vanillyl-6-nonenamide) (/kæpˈseɪsɪn/ or /kæpˈseɪəsɪn/) is an active component of chili peppers, which are plants belonging to the genus Capsicum. It is a chemical irritant and neurotoxin for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact. Capsaicin and several related amides (capsaicinoids) are produced as secondary metabolites by chili peppers, likely as deterrents against certain mammals and fungi. Pure capsaicin is a hydrophobic, colorless, highly pungent (i.e., spicy) crystalline solid.
