Damiana leaves come from the *Turnera diffusa* shrub, which grows in Central and South America. Traditional use focuses on mood balance and sexual health. Many people take it to ease occasional stress, support emotional well-being, and help with mild aphrodisiac effects. It can also promote digestive comfort. Common forms include tea, tincture, and capsules.
Take damiana once or twice daily, with or without food. Dosing varies depending on whether you use the dried herb, an extract, or a tincture. Follow the product label or the advice of a qualified professional.
Do not use damiana if you are pregnant or breastfeeding. This herb may slightly lower blood sugar, so people on diabetes medication should monitor their levels. Long-term use has not been well studied. High doses might cause mild digestive upset or headache.
