American ginseng (Panax quinquefolius) is an herb that grows mainly in North America. It's an endangered species in some states due to high demand.
American ginseng is considered an adaptogen. Adaptogens are a class of substances that are believed to stimulate the body's resistance to physical, environmental, and emotional stressors. American ginseng also contains chemicals called ginsenosides, which seem to affect insulin levels and lower blood sugar.
People take American ginseng for stress, to boost the immune system, for upper airway infections, diabetes, and many other conditions, but there is no good scientific evidence to support most of these uses.
Don't confuse American ginseng with Asian ginseng (Panax ginseng) or Eleuthero (Eleutherococcus senticosus). These are different plants with different effects.
