There are basically two kinds of ginseng: the North-American ginseng (e.g., Wisconsin ginseng) and the Asian ginseng (e.g., Chinese and Korean ginseng). 

Ginseng is the most precious Natural Herb in Chinese medicine.  It has been used for thousands of 
years to improve the overall health of human being by adjusting the internal balance of Yin-Yang within your body. (In ancient Chinese philosophical wisdom, everything in the world can be divided into a combination and balance of Yin (femine, negative, cool, etc...) and Yang (masculine, positive, hot, etc...).) The differences between American ginseng and Asian Ginseng is that American ginseng is of Yin (Cool) in nature; it functions through rejuvernating, refreshing your mind and body to a better state of well-being to give you energy.  Asian ginseng is of Yang (Hot) in nature; it functions through exciting your mind and body to boost your energy.
