| American Ginseng is similar to its Asian cousin, Korean Ginseng. Both varieties are considered true Panax Ginseng types. It was introduced to early American settlers by Native Americans and soon became a major export commodity to the Far East. American Ginseng (xi yang shen) is highly prized for its cooling and moistening nature. American Ginseng benefits energy, enhances immunity and acts as a systemic restorative replenishing the body from stress, over-work and fatigue.
Ginsengs have been used in various traditional medicinal therapies for thousands of years in China and North America. At present, it is also used as an ingredient for formulation of herbal supplements and functional foods. Ginseng is reported to have a wide range of therapeutic and herbal activities, which focus on immunological, stress normalizing, acceleration of metabolism, and anti-oxidant properties.
Asian ginseng (Panax ginseng C.A. Meyer), and American Ginseng (Panax quinquefolius L) are the two major species of ginseng. The primary active ingredients of ginseng are a group of 31 triterpene saponins, also known as ginsenosides. Ginsenosides can be classified into three groups on the basis of the chemical structure of their sapogenins: the panaxatriol group including Re, Rf, Rg1, Rg2, Rh1, the panaxadiol group including Rb1, Rb2, Rb3, Rc, Rd, Rg3, Rh2, Rs1, and the oleanolic acid group including Ro. However, six of them, Rg1, Re, Rb1, Rc, Rb2, and Rd, are the major ginsenosides accounting for over 90% of the total saponin concentration. It is observed that the ratio of individual ginsenosides may be an important factor in the pharmacological and therapeutic effects of ginseng extracts. For example, panaxatriol group has an effect on memory enhancing, whereas the panaxadiol group does not.
The typical source of ginsenosides is from the ginseng root, but current research has found that the ginseng leaf and ginseng berry is alternative sources of ginsenosides. The different total amounts, as well as the specific ginsenoside profile, vary depending on many variables. These variables include the species (i.e. American ginseng or Panax ginseng), growth environment (wild or cultivated), soil and fertility conditions, parts of the plant used, age of the plant, and extraction methods used.
