siberian ginseng products are made from the root. the root contains a mixture of components, common to many plants but occurring together in siberian ginseng, called eleutherosides. among the other ingredients are chemicals called polysaccharides, which have been found to boost the immune system and lower blood sugar levels in laboratory studies using animals. -------------------------------------------------------------------------------- available forms siberian ginseng is available in liquid extracts, solid extracts, powders, capsules, and tablets, and as dried or cut root for tea. it is important to note that there is a wide variation in the quality and amount of siberian ginseng found in different products as well as a significant amount of mislabeling of products containing this herb. in evaluations of commercial products claiming to have siberian ginseng, as many as 25% had no measurable ginseng at all. plus, many formulas for sale were contaminated with contents not marked on the label. care should be taken to purchase siberian ginseng products from reputable manufacturers. ******************************************* if there are any further questions, please do not hesitate to contact me. bring nature to better life! organic herb inc. address:n0.1038shanshuirenjia3rd,kaiyuanroad,xingsha,changsha,china contact: ms.lily liu phone: +86 135 1747 5149 fax: +86 731 4023669 email: lily@organic-herb.com msn messenger： lily@organic-herb.com website: http://www.organic-herb.com
