Panax quinquefolius — American ginseng

Facts

American ginseng is distributed over the eastern half of North America, and is present in all New England states, though rare and protected in most. The importance of American ginseng as a medicinal and tonic herb has resulted in much wild collecting of this plant. This is illegal in most states, as well as being destructive and unnecessary, as the plant can be readily grown in cultivation. The active part of the plant is the root, used in Chinese and Native American traditional medicine.
