Ginseng Varieties This valued plant known as ginseng can be purchased in different forms. White ginseng is what the root is called before any processing occurs. White is the natural color of the root after it is harvested and washed. When dried, the root becomes a light brown color. When the ginseng root is processed using steam and heat, it becomes red. This procedure is done in order to preserve the plant and its constituents. The heat process is thought to help stimulate the active properties in ginseng and some herbalists believe that the red ginseng is more stimulating than the white.2 There are a variety of types as well as grades of ginseng and ginseng products. This is due in part to differences in age, source, part of the root used and the preparation. The old wild plants are the most desirable because of their nutritional content which is believed to increase with age. The western world often treats the different ginseng varieties the same. But in traditional Chinese medicine, the various types are thought to possess distinct properties. They are each valued for their differences and used for Divergent purposes. The Asian variety of ginseng (Panax ginseng) grows principally in Korea, Japan and China. Centuries ago the ginseng plant grew wild and was abundant. But because of the claims of its healthy properties, it has been depleted in its natural state almost to the point of extinction. Now it is grown commercially for export and local medicinal use. The Asian ginseng is often exported to the western world. It is unfortunate but most of the ginseng grown now is cultivated using pesticides to promote mass production. The Asian plant has similar composition to the American variety with some variations. It contains ginsenosides, the active ingredients, between one and three percent. There are at least thirteen of these different triterpenoid saponins, referred to as ginsenosides. The Asian contains Rb1, Rb2, Rc, Re, and Rg1.3 The Wild American variety of ginseng is still found in its natural state. This variety grows naturally and organically but is hard to find. There is an increasing amount of American ginseng being cultivated and grown for commercial use. Fertilizers and pesticides along with modern farming equipment aid in the production and high yield of this variety of ginseng. The American ginseng is thought to be less stimulating than the Asian variety. The American ginseng contains primarily the ginsenosides Rb1 and Re and does not contain Rb2, Rf and sometimes not Rg1.4 Generally, the American ginseng is thought to possess more of a sedative effect than the Asian ginseng. Differences in the chemical structures of the ginseng roots makes the identification process between the varieties easier. Siberian ginseng, though not considered a “true ginseng,” contains similar properties to the other varieties. It was discovered in Siberia but is now cultivated around the world. Some of the saponins found in this variety are not the same as the Asian and American. But is known to have the same tonic and stimulant effect as the “true ginseng.”5 It is believed to be less potent than either the American or Asian ginsengs. Research has documented may of its valuable adaptogenic capabilities.
