Historically, all parts of the plant have been used medicinally, but the bark and roots are most highly utilized. Indigenous tribes in Brazil use the tea for treating neuromuscular problems, rheumatism, influenza, cardiac and gastrointestinal asthenia and to prevent baldness. In Europe, muira puama has a long history in herbal medicine as an anti-rheumatic, aphrodisiac, a tonic for the nervous system, and for the treatment of gastrointestinal disorders.

Muira puama is included in combination products as a remedy for sexual impotence. Recent studies show promising evidence that it may increase sexual vitality and treat erectile dysfunction in males. Muira puama has also been used by bodybuilders and weight lifters to improve physical performance. This is due to proposed testosterone-like effects of muira puama.

If buying preparations of muira puama, do so with caution, as Liriosma ovata and Acanthea virilis are commonly incorrectly sold as muira puama.
