Panax quinquefolius
A slow-growing, long-lived North American native woodland perennial valued for cooling, calming medicinal roots with adaptogenic and cardiotonic properties, harvested in fall after 5–10 years, and featuring a fleshy tuberous rhizome and palmately compound leaves.
Common Names
American Ginseng, Ginseng, Sang
Summary
American ginseng is a herbaceous perennial native to eastern North America, thriving as a shade-tolerant understory plant in rich forests. It features a palmately compound leaf arrangement with typically three leaves at the summit, later producing 3–5 compound leaves with 3–7 leaflets, and an aromatic, often forked root; in summer it bears greenish-white flowers and, in autumn, bright red berries.
Its cultivation favors full shade in rich, moist, well-drained forest soil with slightly acidic to neutral pH (roughly 5.0–6.0) and high calcium; plants are propagated by seed (stratified 18–22 months) or root cuttings and spaced about 20 cm apart; hardy in USDA zones 3–7. Harvest occurs in autumn after berry ripening; wild populations are depleted, and much of the crop is cultivated to reduce pressure on native stands, with trade controls under CITES Appendix II. Leaves and roots are used to make tea and as an adaptogen and tonic, with ginsenosides in the roots.
