General description

Ginseng is a popular herb. A common name for ginseng is "man-root." This is because the root is shaped like a person. It has benefits for the whole body. The medicinal part is made of the dried main and lateral root and root hairs.

Ginseng commonly refers to Panax quinquefolius L. (American ginseng) or Panax ginseng C.A. Meyer (Korean ginseng). Siberian Ginseng comes from a slightly different family than Panax. It’s called Eleutherococcus senticosus Maxim. Both families of ginseng share the same chemical constituents. Panax ginseng contains saponin glycosides. These are also known as ginsenosides. Siberian ginseng doesn’t contain ginsenosides. But it has another class of compounds called eleutherosides. In all cases, they’re called adaptogens.
