US Patent 7709539 Therapeutic use of resveratrol for hyperglycemia

Resveratrol, an antioxidant found in various fruits, vegetables, grapes, and red wines, has been shown to have free radical scavenging, anti-inflammatory and anti-thrombogenic activities in biological systems. Moreover, resveratrol has also been shown to be a good cancer preventive chemical and has been recommended as a food supplement for health benefits. Resveratrol can effectively lower the blood sugar in both type 1 (insulin-dependent diabetes mellitus, IDDM) and type 2 (insulin-independent diabetes mellitus, NIDDM) diabetic rats. Resveratrol could also delay the onset of the insulin-resistant phenotype in experimental rats with prolonged injection of insulin. Further, resveratrol simultaneously slows down the body weight increment compared with untreated insulin resistant animals.
