Summary

American ginseng (Panax quinquefolius, Panacis quinquefolis) is a herbaceous perennial plant in the ivy family, commonly used as an herb in traditional medicine, including traditional Chinese Medicine. It is native to eastern North America, though it is also cultivated in China. Since the 18th century, American ginseng (P. quinquefolius) has been primarily exported to Asia, where it is highly valued for its cooling and sedative medicinal effects. It is considered to represent the cooling yin qualities, while Asian ginseng embodies the warmer aspects of yang.

Traditional medicine

The plant's root and leaves were used in traditional medicine by Native Americans. Since the 18th century, the roots have been collected by "sang hunters" and sold to Chinese or Hong Kong traders, who often pay high prices for particularly old wild roots. Originally, American ginseng was imported into China via subtropical Guangzhou, the seaport next to Hong Kong. Since American ginseng was originally imported into China via a subtropical seaport, Chinese doctors believed American ginseng must be good for yin, because it came from a hot area. They did not know, however, that American ginseng can only grow in temperate regions. Nonetheless, the root is legitimately classified as more yin because it generates fluids.There is no evidence that American ginseng is effective against the common cold or how severe the infections are. There is tentative evidence that it may lessen the length of sickness when used preventively.Cold-fX is a product derived from the roots of North American ginseng (Panax quinquefolius). The makers of Cold-fX were criticized for making health claims about the product that have never been tested or verified scientifically. Health Canada's review of the scientific literature confirmed that this is not a claim that the manufacturer is entitled to make. (Source: Wiki)
