JHM, look through a lot of the posts here in the forum, or even google for pictures of ginseng. You have to study it really hard until it is imprinted into your mind. Although your plant has 5 leaves with serrated edges, it is not close to what ginseng leaves look like. Ginseng has a single stem, which branches into 3 or 4 stems (prongs). At the end of each prong will be 5 leaves (3 big ones facing outward, 2 smaller leaves facing back towards the main stem). Ginseng stems are never red or pink colored. At the point where the main stem branches out into 3, there is also a very thin small shoot that comes upward, forming the crown, where the berry pod grows. The ginseng leaves have smaller serrations that what you picture shows, and they sort of form a widows peak at the tip. As for the root, it should be a creamy yellow color, with notable hairs coming off it at various locations, and a growth neck at the base of the stem.
It's hard to figure out on your own the first time, but you'll get it. The more you see it, the easier it is to identify it.
