Korean Ginseng is the most famous and popular Ginseng in use among herbalists. It is highly regarded for its adaptogenic properties. The high quality Solaray Korean Ginseng contains the prized ginsenoside ratio Rg1 to Rb1 at a minimum of 0.5. This chemical structure and its effect on the body seperate this five-year old Ginseng from young or poorly grown Korean Ginseng, its less expensive rootlets, and American Ginseng.
