American Ginseng promotes Yin energy, cleans excess Yang in the body, and calms the body. The reason it has been claimed that American ginseng promotes Yin (shadow, cold, negative, female) while East Asian ginseng promotes Yang (sunshine, hot, positive, male) is because, according to traditional Chinese medicine, things living in cold places or northern side of mountains or southern side of rivers are strong in Yang and vice versa, so that the two are balanced.
