American ginseng is a small plant native to the forests of the northern and central United States.
The root of American ginseng is used medicinally. American ginseng contains ginsenosides, which stimulate the immune system and fight fatigue and stress. The type and percentage of ginsenosides in American ginseng is somewhat different than the Asian ginseng variety. American ginseng is considered superior for gastrointestinal problems and is commonly used in the U.S. to improve athletic and mental performance. Other studies are examining the use of American ginseng in the treatment of cancer, diabetes, cardiovascular disease, immune suppression, aging and depression.
