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.

Bacopa (Bacopa monnieri)Bacopa, also known as Water Hyssop or Brahmi, is a creeping succulent perennial that can grow to about 20 inches. It features spatula-shaped fleshy leaves and pale blue or white flowers on slender stalks. Thriving in marshlands and along the edges of mangrove swamps in warmer temperate and tropical climates - especially southern Asia - it develops into dense mats on mudflats. This herb has been a cornerstone of Ayurvedic medicine for supporting cognitive function and treating various nervous system disorders, and it is increasingly recognized in Western herbalism for its brain-enhancing properties.
Ginseng (Panax ginseng)Asian or Korean ginseng (Panax ginseng) is a perennial reaching about 3 ft (1 m) in height, with toothed oval leaves and a cluster of small green-yellow flowers. Its root is legendary for its adaptogenic qualities, boosting energy and physical stamina, slowing aspects of aging, and fortifying the body against stress. Ginseng is considered more warming (especially red ginseng, which is steamed before drying) and thus suited for older, easily fatigued individuals who feel cold.
