Fermented white ginseng root extract
Native to mountain forests of East Asia, Panax ginseng (from “Jen shen”, or “man herb”) is now cultivated in China, Japan, Russia and Korea. For over two thousand years, the root of P. ginseng has been used as a tonic, energizer, to help aid concentration, to help reduce anxiety and emotional instability and as a restorative to promote health and longevity 1,2,3. It has a long history of traditional use in China for improving memory 4, and has been used traditionally by many cultures as an “adaptogen” (a substance that is able to help the body adapt to environmental or internal stresses without altering normal physiology) 3,5.
P. ginseng roots are prepared either by steaming and then drying to produce red ginseng or by sun-drying, to produce white ginseng. The roots contain ginsenosides (glycosylated triterpenoid saponins), a volatile oil, sterols (including beta-sitosterol), starch, polysaccharides, caffeine, theophylline, theobromine, vitamins (B1, B2, B12, nicotinic acid, pantothenic acid, biotin), choline, fats, and minerals (zinc, copper, manganese, calcium, and iron). Panax spp. are best known, however, for their over 150 ginsenosides, which appear to be responsible for the root’s benefits for humans 6,7.
Research indicates that ginsenosides are poorly absorbed, and there is some evidence that ginsenoside metabolites formed by intestinal bacteria after oral intake may account for the root’s health benefits. It has also been demonstrated that individual responses to ginseng supplements can be affected by specific gut flora populations 8.
Fermented ginseng products may be superior to standard non-fermented ginsengs 9,10,11,12,13. In human oral studies, intake of P. ginseng has been shown to support healthy brain and cognitive function, mental alertness and focus 14,15,16. Improvements in mood, 17 quality of life 18,19, overall wellness 20 and healthy immune system function 20,22 have also been documented.
The German Commission E reports that P. ginseng has no known side effects, contraindications or interactions with other drugs 2. A systematic review of adverse effects and drug interactions was published for Panax ginseng . The authors found that data from clinical trials suggest that the incidence of adverse events with ginseng preparations is similar to that of placebo 23. Animal toxicity studies found ginseng to be very safe, with no teratogenicity or mutagenicity 24.
