American ginseng is an herbaceous perennial plant in the ivy family, commonly used in traditional and modern Chinese herbal medicine. Although this plant is native to eastern North America, it is also abundantly cultivated in China, where it is often called huaqishen or xiyangshen. American ginseng contains dammarane-type ginsenosides, or saponins, as the major biologically active constituents. Dammarane-type ginsenosides include two classifications: 20(S)-protopanaxadiol (PPD) and 20(S)-protopanaxatriol (PPT). American ginseng contains high levels of Rb1, Rd (PPD classification), and Re (PPT classification) ginsenosides—higher than that of Panax ginseng in one study, according toCarol Cheow, general manager of Cactus Botanics.
She added that American ginseng may be used in supplements for the following condition-specific support: blood circulation/healthy blood, immune system, central nervous system, and endocrine system. It also has shown good sedative and anti-pyretic properties.
