Muira puama, also called “potency wood,” is a tree that is native to the Brazilian Amazon and other parts of the Amazon rainforest. The small, white flowers have a pungent fragrance similar to jasmine. Historically, all parts of Muira Puama have been used medicinally, but the bark and roots are the most-utilized parts of the plant. It has long been used in the Amazon by indigenous peoples for a number of purposes, including tonifying digestion and supporting the nervous system. Here is a quote from an article written by Medicine Hunter, Chris Kilham on a direct experience he has had with Muira Puama in its native setting; "While there we ventured into the rain forest with native guides who showed us Catuaba and Muira Puama trees growing in different places. We also witnessed the harvesting of catuaba bark and its subsequent sale to a local buyer. We learned that most natives use these plants by placing a small handful of their combined barks in a glass of room-temperature water, let the herbs sit overnight, and drink the resulting amber infusion in the morning."
Scientists have identified a group of sterols including beta-sitosterol, thought to be responsible for Muira Puama's effects. The science on this plant is still evolving, but it has been under investigation since the 1920s. More recent investigation of the phytochemical composition has revealed the presence of free long-chain fatty acids, sesquiterpenes, monoterpenes, and novel alkaloids. As with many traditional medicines it is likely that it is not any one chemical that is responsible for the activity, rather the entire plant extract.
