Homodihydrocapsaicin is a capsaicinoid and analog and congener of capsaicin in chili peppers (Capsicum). Like capsaicin it is an irritant. Homodihydrocapsaicin accounts for about 1% of the total capsaicinoids mixture[2] and has about half the pungency of capsaicin. Pure homodihydrocapsaicin is a lipophilic colorless odorless crystalline to waxy compound. It produces "numbing burn" in the throat and is one of the most prolonged and difficult to rinse out. On the Scoville scale it has 8,600,000 SHU (Scoville heat units).[1]
