Damiana (Turnera diffusa)
Overview
Damiana (Turnera diffusa) is an aromatic shrub growing up to about 6½ ft (2 m), with pale green leaves and single yellow flowers. It is traditionally viewed as an aphrodisiac by Central American cultures, but modern herbalists often prize it more broadly as a mild tonic for nervous exhaustion, mild depression, and stress-related low libido. It also has mild diuretic, antiseptic, and laxative properties.
