Specifications:                                                       -Resveratrol 50%-Resveratrol 98%Latin Name: Polygonum CaspidatumAppearance: Fine Deep Brown(50%), White(98%) PowderPart of the Plant Used: RootCAS No.: 501-36-0Introductions:Resveratrol (trans-resveratrol) is a phytoalexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi. Resveratrol has also been produced by chemical synthesis[1] and is sold as a nutritional supplement derived primarily from Japanese knotweed. In mouse and rat experiments, anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects of resveratrol have been reported. Most of these results have yet to be replicated in humans. In the only positive human trial, extremely high doses (3–5 g) of resveratrol in a proprietary formulation have been necessary to significantly lower blood sugar. Resveratrol is found in the skin of red grapes and is a constituent of red wine, but apparently not in sufficient amounts to explain the French paradox. Experiments have shown that resveratrol treatment extended the life of fruit flies, nematode worms and short-lived fish but it did not increase the life span of mice.Jianhe Biotech's resveratrol is extract from Polygonum Caspidatum, which is rich in Trans-Resveratrol.
