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.

Special Precautions and Warnings
Breast-feeding: There isn't enough reliable information to know if American ginseng is safe to use when breast-feeding. Stay on the safe side and avoid use.
Children: American ginseng is possibly safe when used short-term. A specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences) has been used in doses of 4.5-26 mg/kg by mouth daily for 3 days in children 3-12 years of age.
Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: American ginseng products that contain chemicals called ginsenosides might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don't use American ginseng that contains ginsenosides. Some American ginseng extracts have had the ginsenosides removed.
