The natives of South America refer to tonka bean oil as the Oil of Initiation.
Due to its wonderful smell, Tonka Bean oil has been used widely in the perfume industry. It is fairly new on the essential oil market, though it has been in use in South America for a long time as an extract made by soaking the beans in rum. Traditional herbal uses of Tonka Bean include treating ear aches, coughs, lung congestion, asthma, and for treating cuts, bruises, rheumatism, and even snake bites. Tonka Bean is a fixative oil and blends especially well with citrus and floral oils. Tonka Bean is a natural aphrodisiac. The active ingredient in Tonka Bean essential oil is coumarin which is a blood thinner and is used to prevent blood clotting. Coumarin also acts as a natural pesticide.
