The term ginseng refers to several species of the genus Panax . For more than two thousand years, the roots of this slow-growing plant have been valued in Chinese medicine. The two most commonly used species are Asian ginseng ( Panax ginseng C.A. Meyer), which is mostly extinct in its natural range but is still cultivated, and American ginseng ( P. quinquefolius L.), which is both harvested from the wild and cultivated. Panax ginseng should not be confused with Siberian ginseng ( Eleutherococcus senticosus ). In Russia, Siberian ginseng was promoted as a cheaper alternative to ginseng and was believed to have identical benefits. However, Siberian ginseng does not contain the ginsenosides that are present in the Panax species, which are believed to be active ingredients and have been studied scientifically.
American ginseng synonyms: Anchi ginseng, Canadian ginseng, North American ginseng, Ontario ginseng, P. quincefolium, red berry, ren shen, sang, tienchi ginseng, Wisconsin ginseng.
