Panax quinquefolius, commonly known as American Ginseng .The plant’s forked root and leaves were traditionally used for medicinal purposes by Native Americans. Since the 1800s, the roots have been collected by “’sang hunters,” and sold to Chinese or Hong Kong traders, who often pay very high prices for particularly old wild roots.[3]

American Ginseng was formerly particularly widespread in the Appalachian and Ozark regions (and adjacent forested regions such as Pennsylvania and New York State), but due its popularity the wild plant has been overharvested, and is thus rare in most parts of the United States.[4] It is also grown commercially, under artificial shade, in fields in Wisconsin and Minnesota,
Both American ginseng (Panax quinquefolius) and Asian ginseng (Panax ginseng) roots are taken orally as adaptogens, aphrodisiacs, nourishing stimulants,[citation needed] and in the treatment of type II diabetes, as well as sexual dysfunction in men. The root is most often available in dried form, either whole or sliced. Ginseng leaf, although not as highly prized, is sometimes also used; as with the root it is most often available in dried form.

This ingredient may also be found in some popular energy drinks: usually the “tea” varieties or functional foods. Usually ginseng is in subclinical doses and it does not have measurable medicinal effects.[citation needed] It can be found in cosmetic preparations as well, with similar lack of effect.
