Several varieties of ginseng grow in various places around the world, with the three major species being American, Siberian and Korean. Each species has its own chemical properties. For instance, Siberian ginseng is of a different genus than the other two ginsengs, but it possesses many of the qualities of Korean ginseng. Siberian ginseng is an adaptogen, although perhaps more mild than Korean ginseng.
Siberian ginseng is the least expensive of the three ginsengs.
Wild American ginseng is a true ginseng and was held to be of great value even in the early days of pioneer settlement in America. Its ginsenosides differ from those of Korean ginseng, although the two share similar properties. It is the most expensive of the three ginsengs. Each Korean ginseng capsule contains 410 mg of the finest Korean ginseng, with a guaranteed potency of 12 mg ginsenosides per capsule. Take 1 capsule with a meal twice daily.
