5. Function
1) Anti-oxidation; A good dyeing agent
2) Antagonic action on platelet activating factor (PAF), demonstrating pharmacological actions such as anti-thrombus, anti-myocardia ischemia, improving the microcirculation and prophylaxis of artery cirrhosis;
3) Adjusting cholesterol level; In vitro research s ests that myricetin in high concentration is capable of modifying LDL cholesterol in a manner that enhances its uptake by white blood cells
4) Decreasing blood sugar; It can be used as food additive for diabetics;
5) Protecting liver;
6) Anti-inflammation and anti-infection;
7) Acting as inhibitor of matrix metalloproteinase; It can be used for prevention and treatment of cardiovascular disease and tumor;
