[Panax quinquefolius (American); Panax ginseng (Korean)]
Of the two major species of Ginseng, the American, farm grown in Wisconsin and Canada, is considered the best. Siberian Ginseng (Eleutherococcus senticosus) belongs to a different genus and has a different makeup of active ingredients. While considered inferior, it's put to much the same uses as the Panax species and is often deceptively sold as Panax. Given the reputation of American ginseng, much of the Korean variety is put up in red, white and blue packages and sold as "Wisconsin Ginseng", even by Asian markets here in the USA. The photo specimens, from a Korean market in Los Angeles, were 6-3/4 inches long and weighed 1-3/8 ounce (left) and 2 ounces (right).
