Resveratrol is an active component which is extracted from Giant Knotweed. Its pharmacology function can be described as follows: Antibiotic antivirus, anti-tumor, resists the hepatitis, suppresses the agglutinate production with plain B2 of thrombus of blood platelet. It can prevent low density fat albumen from oxidize, have potential prevention and cure cardiovascular disease, gives protection against cancer, antivirus and immune regulating action, its function is shown as its anti-oxidant characteristic mainly.Clinical practice: Used in the acute jaundice type infective hepatitis, blood silt and menorrhoea, rheumatism type arthralgia, muscle bone-ache , sand drench , blood drenching , bronchitis , damp and hot gall stone; It is too high to be used in the cholesterolemia and triglyceride; It is anti-oxidant to be used in , slowed aging.

Resveratrol is present in many plants and fruits, including red grapes, eucalyptus, spruce, blueberries, mulberries, peanuts, giant knotweed. Also red wine contains a lot of it. Resveratrol is a type of polyphenol called a phytoalexin, a class of compounds produced as part of a plant's defense system against disease. It is produced in the plant in response to an invading fungus, stress, injury, infection, or ultraviolet irradiation.Resveratrol has been shown to reduce tumor incidence in animals by affecting one or more stages of cancer development. It has been shown to inhibit growth of many types of cancer cells in culture. Evidence also exists that it can reduce inflammation. It also reduces activation of NF kappa B, a protein produced by the body's immune system when it is under attack. This protein affects cancer cell growth and metastasis.Several studies have demonstrated that resveratrol is an effective antioxidant. It inhibits lipid peroxidation of low-density lipoprotein (LDL), prevents the cytotoxicity of oxidized LDL, and protects cells against lipid peroxidation . It is thought that because it contains highly hydrophilic and lipophilic properties, it can provide more effective protection than other well-known antioxidants, such as vitamins C and E . On the other hand, it is less effective than the antioxidants quercetin and epicatechin found in red wine. Reduced platelet aggregation has also been demonstrated in studies on resveratrol, further contributing to its prevention of atherosclerosis. To date, most of the research on resveratrol''s antioxidant and anti-platelet properties has been done in vitro (in an artificial environment using test-tube or tissue-culture preparations). Further studies in animals and humans are necessary to determine whether resveratrol supplementation makes sense.

What is Resveratrol ?

Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer. 3W’s Resveratrol is extracted from Polygonium cuspidatum and grape skin, it’s rich with Both cis- resveratrol and trans-resveratrol .

Plant origin and Distribution:

Polygonum cuspidatum belongs to polygonaceae, is a kind of perennial shrubs. It originates in East Asia, and is widely implanted the middle and south part of China,such as Jiangsu, Jiangxi,Fujian, Shangdong, Henan, Shaanxi and Sichuan Province. We use the wild polygonum cuspidatum in Shaanxi Province as our material.
