Ambrein is a triterpene alcohol that is the chief constituent of ambergris, a secretion from the digestive system of the sperm whale, and has been suggested as the possible active component producing the supposed aphrodisiac effects of ambergris.[1] Although ambrein itself is odorless, it serves as the biological precursor for a number of aromatic derivatives such as ambroxan and is thought to possess fixative properties for other oderants.

It has been shown to act as an analgesic[2] and it has been proven to increase sexual behavior in rats,[3] providing some support for its traditional aphrodisiac use.
