Purchase a one pound package of Raintree Nutrition's damiana leaf powder (Turnera aphrodisiaca) which is rich in the naturally occurring plant chemicals that this plant is regarded for. Damiana's chemical composition is complex and its components have not been identified completely. The leaves contain up to 1% volatile oil that is comprised of at least 20 constituents. Damiana leaves also contain tannins, flavonoids, beta-sitosterol, damianin (a brown, bitter substance), and the glycosides gonzalitosin, arbutin, and tetraphyllin B. Raintree's damiana has been sustainably wild-harvested in the Brazilian Amazon and has been milled into a fine powder which is suitable to stuff into capsules or to prepare your own teas, tinctures or extracts.
