What it is

Muira puama is a small Amazonian tree whose root and bark are used as a nerve tonic and aphrodisiac. Active compounds include plant sterols, triterpenes, and alkaloids though the precise active compounds have not been definitively identified.

Traditional use

Used for centuries by Amazonian indigenous peoples and Brazilian traditional healers for sexual debility, neuromuscular weakness, and as a general tonic. Known as 'potency wood' in the Amazon. Introduced to European herbalism in the early 20th century.

What modern research suggests (Traditional-only/Early)

Two Brazilian pilot studies showed improved libido and sexual function in women. An open study in men showed improved erections and libido. Animal studies confirm aphrodisiac and neuroprotective effects. Evidence remains limited and low quality.

How people use it

Tincture: 1-3ml twice daily. Capsule: 500-1000mg root/bark extract twice daily. Take consistently for at least 4-6 weeks. Traditional combination with ginkgo biloba.

Safety + interactions

Limited formal safety data. Long traditional use suggests reasonable safety at normal doses. Avoid in pregnancy. Species verification is the most important safety step.

May interact with: Medications metabolised by CYP enzymes

Name clarity note

MAJOR NAME CLARITY WARNING: The trade name 'muira puama' is used for multiple Amazon plant species. Ptychopetalum olacoides is the primary accepted species but products may contain other species or adulterants. Some products incorrectly list Liriosma ovata as the botanical. Adulteration is common due to high price and demand. Always buy from suppliers with authenticated species identification.

Quality notes

Tincture in 80%+ alcohol is the most effective extraction method. Look for root and bark material specifically. Brazilian-sourced product with supplier traceability is important. DNA-authenticated products are preferred.
