Flavonoids generally refer to a series of compounds composed of two benzene rings (a- and b- rings) with phenolic hydroxyl groups connected by the central three carbon atoms. The basic parent nucleus of flavonoids is 2-phenylchromogen. The structures of flavonoids are often connected with phenolic hydroxyl, methoxy, methyl, isopentenyl and other functional groups. In addition, it often combines with sugar to form glycosides. Its functions include:

1. anti aging  

Flavone is a powerful antioxidant, which can effectively remove oxygen free radicals in the body. For example, anthocyanin and anthocyanin can inhibit the overflow of lipid peroxides at all stages. This ability to prevent oxidation is more than ten times that of vitamin E. this antioxidant effect can prevent cell degradation, aging and cancer.      

2. improve blood circulation  

Flavonoids can improve blood circulation and reduce cholesterol. Flavonoids in xiangtianguo also contain a PAF anticoagulant factor, which greatly reduces the incidence of cardiovascular and cerebrovascular diseases and improves the symptoms of cardiovascular and cerebrovascular diseases. The flavonoid compound known as anthocyanin acid has been proved in animal experiments that it can reduce blood glucose by 26% and triglyceride by 39%. This hypoglycemic effect is very magical, but more important is its effect on stabilizing collagen. Therefore, it has a good effect on retinopathy and capillary embrittlement caused by diabetes.

3. treatment  

Flavonoids can inhibit the exudation of inflammatory biological enzymes, promote wound healing and pain relief, and can be used in various sensitive diseases due to its strong antihistamine property.
