Ginseng has been a part of the herbal medicine, throughout centuries. Though, more popular as an indispensable part of the traditional Chinese medicine, this herb has been used by native Americans too. While, the former used oriental (Asian) ginseng (panax ginseng), the latter were familiar with American ginseng (panax quinquefolium). The third type, which is a close relative of the oriental ginseng, is also used for therapeutic purposes. Benefits of this herb include its ability to enhance the efficiency of the immune system, as a stimulant and an aphrodisiac. This herb is also used in the treatment of various medical conditions. Though, side effects are reported very rarely, there are some cases, where this herb has been associated with some negative effects.
