Almost all hot peppers are the same species (Capsicum annuum). The principle medicine is capsacian. Since capsacian is also the principle element causing heat, I suspect that all hot peppers will share many/most of cayenne’s benefits. That said, If I were to buy or grow one to tincture, I’d probably stick with cayenne…better the hot devil we know. LOL
