Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy

What is Muira Puama?

Muira puama (Ptychopetalum olacoides) is a small tree from the Amazon whose bark and root have a long folk reputation as an aphrodisiac and nerve tonic. It is a common ingredient in 'male enhancement' and libido supplements, usually alongside herbs like catuaba and maca.

What Muira Puama is commonly used for

In supplements, Muira Puama is most often included for men's vitality support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.

How Muira Puama works

Its proposed mechanisms include mild effects on the nervous system and circulation, but the active compounds and how they work are poorly characterised. The aphrodisiac reputation rests mainly on tradition rather than well-defined pharmacology.

What the evidence says

Here's an honest snapshot of what published research suggests about Muira Puama — including where the evidence is limited.

• A couple of small, older, mostly uncontrolled studies reported improvements in libido or erectile function, but the evidence is weak and low quality. (PubMed research)
• There is little rigorous, modern human research to confirm any specific effect. (PubMed research)

Typical dosage used in studies

Side effects and safety

Generally considered well tolerated in typical amounts, but safety data are limited, particularly for long-term use.
