Historical note Gin refers to man and seng to essence in Chinese, whereas Panax is derived from the Greek word pan (all) and akos (cure), referring to its use as a cure-all. Ginseng is a perennial herb native to Korea and China and has been used as a herbal remedy in eastern Asia for thousands of years. It is considered to be the most potent Qi or energy tonic in TCM. Modern indications include low vitality, poor immunity, cancer, cardiovascular disease and enhancement of physical performance and sexual function. However, a recent systematic review of RCT found that the efficacy of ginseng root extract could not be established beyond doubt for any of these indications (Coon & Ernst 2002).
