Damiana (Turnera diffusa)

Tier 4 — risky / avoid · Libido · Mood · Traditional

A traditional Mexican and Central American herb used as an aphrodisiac, mood elevator, and mild anxiolytic. Contains arbutin, damianin, flavonoids, and volatile oils. One combination product (ArginMax) showed sexual function improvements in women, but damiana's individual contribution is unclear. Some aromatase inhibition and mild CNS stimulation documented preclinically. Traditional use is extensive; modern monotherapy evidence is weak. Generally well-tolerated.

Dose: 400–800 mg dried leaf or 2–4 mL liquid extract, 1–2 times daily
