Korean ginseng is a native of Eastern China, and American ginseng is a native of North America.
The root of both species is highly prized for medicinal properties. Traditionally, the crop has been harvested from the wild. Its high value has led to excessive exploitation resulting in the virtual extinction of the plant in its native habitat both in Asia and North America. As a result, ginseng is being developed as a horticultural crop on both sides of the Pacific. Ginseng's high price on the world markets, despite increased production, has created worldwide interest in this crop.
