Muira Puama (Ptychopetalum) is native to the Amazon rainforest and is a small Brazilian tree that grows throughout the Amazon basin, where it is known as "Wood of Power". The natives of the Amazon use this herb for both men and women. Muira Puama is an adaptogen plant and has been used by indigenous tribes as an aphrodisiac to control impotence and sexual inadequacy. Muira Puama is very popular among couples and is used by people who enjoy an active lifestyle.
It is used interchangeably in South American systems of herbal medicine. Native peoples along the Rio Negro River in the Brazilian Amazon use the stems and roots of young plants as a tonic to manage neuromuscular problems; it is also valued there as a preventative for baldness.
