What is Giant Knotweed Extract ？
Giant Knotweed Extract is a non-flavonoid phenolic substance, belonging to the plant antitoxin of stilbens. The research found that a large number of high purity components of resveratrol can be extracted from the Polygonum cuspidatum. Resveratrol extract has the efficacy of antioxidation, free radical scavenging, prevention of aging, antitumor, protection of cardiovascular, phytoestrogen and liver preservation.

Benefits and effects of Polygonum Cuspidatum extract
1) Antitumor activity
By inhibiting cytochromase, inducing detoxifying enzyme, inhibiting protein kinase, antagonistic estrogen receptor, promoting tumor cell differentiation and apoptosis, Polygonum Cuspidatum Root Extract can reach the function of antitumor activity obviously.
2) Prevention and control of cardiovascular disease
Polygonum extract has the function of anti-hemagglutination and anti-low density lipoprotein oxidation to prevent the occurrence of atherosclerosis and coronary heart disease, and to protect the cardiovascular. The experiment showed that resveratrol can reduce the incidence and duration of ventricular tachycardia. Because of the strong protective effect , mortality was reduced.
3) Anti-oxidation and anti-free radical action
Researches have shown that Giant Knotweed Extract Resveratrol has antioxidant and free radical effects. It could inhibit the liver microsomal, brain mitochondria and synaptosome oxidative damage in the process of the formation of DNA. Also, resveratrol extract has a good control effect for viral hepatitis, Parkinson's disease, alzheimer's disease and other diseases.
4) Function of protecting liver
Giant Knotweed Extract Resveratrol has strong inhibition to the lipid peroxidation, can reduce serum lipid and liver, reduce the accumulation of lipid peroxide in the body, protect the liver from damage. It can induce liver change in the phenotype of fibroblasts, significantly reduce the proliferation of fibroblasts, and at the same time reduce the expression of type I collagen and the secretion of matrix metalloproteinases，which has important significance for the treatment of liver fibrosis and liver cancer.
With the deepening of the research on nature resveratrol, researchers found that resveratrol also has immune regulation, antiviral, anti bacteria and fungi, resist allergy, radiation protection, prevention of acute infectious atypical pneumonia (SARS), and any other value.
Applications of our Giant Knotweed Extract
Applied in health product field
It is effective to reduce the risk of cardiovascular disease and total cholesterol. Nature resveratrol, as an antioxidant, has the function of vascular dilatation, which can effectively inhibit the abnormal expression of tissue factor and cytoplasm in vascular cells, thus preventing the occurrence of cardiovascular disease. It can also prevent and control ischemic cerebral apoplexy such as cerebral infarction.
