Wisconsin ginseng- Panax quinquefolius
American ginseng (Panax quinquefolius) is a herbaceous perennial plant in the ivy family, commonly used as Chinese or herbal medicine. An extract is sold as Cold-fX. It is native to eastern North America, though it is also cultivated in places such as China.
There is little evidence to support that American ginseng is effective in the common cold.All trials evaluating the efficacy were funded by the manufacturer and there has been poor data reporting.Health Canada's Natural Health Product Directorate states that it claims to "help reduce the frequency, severity and duration of cold and flu symptoms by boosting the immune system".
The plant's forked root and leaves were traditionally used for medicinal purposes 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 very high prices for particularly old wild roots.It is also known by its Chinese name huaqishen.
There is no evidence that American ginseng is effective in those infected with the common cold.The effect of preventative use is not clear.When used preventatively it makes no difference on the rate of infections.It also appears to have no effect on how bad the infections are.There is tentative evidence that it may lessen the length of sickness when used preventatively.
Individuals requiring anti-coagulant therapy such as warfarin should avoid use of American ginseng. Not recommended for individuals with impaired liver or renal function. It is not recommended in those who are pregnant or breastfeeding. Other adverse effects include: headaches, anxiety, trouble sleeping and an upset stomach.
American ginseng was formerly particularly widespread in the Appalachian and Ozark regions (and adjacent forested regions such as Pennsylvania, New York and Ontario), but due to its popularity and unique habitat requirements, the wild plant has been overharvested, as well as lost through destruction of its habitat, and is thus rare in most parts of the United States and Canada.Ginseng is also negatively affected by deer browsing, urbanization, and
