What is Quercetin?
Quercetin, has antioxidant properties and can be used as a pharmaceutical. It has excellent expectorant and cough-relieving properties, and also has some anti-asthmatic effects. It also has the potential to lower blood pressure, enhance capillary resistance, reduce capillary fragility, lower blood lipids, dilate coronary arteries, and increase coronary blood flow. It is used to treat chronic bronchitis and has an adjunctive therapeutic effect in patients with coronary heart disease and hypertension.
Quercetin is widely available, found in the stems, bark, flowers, leaves, buds, seeds, and fruits of many plants. Its preparation methods currently include extraction and separation, acid hydrolysis, and enzymatic conversion, with enzymatic conversion being the most practical.
Key Features
1.Eliminating Senescent Cells
Research from the Chinese Academy of Sciences has found that combining chemotherapy with dasatinib and quercetin can eliminate chemotherapy-induced senescent fibroblasts, thereby inhibiting post-chemotherapy lung metastasis, providing a new approach to improving chemotherapy efficacy.
2.Anti-tumor and Anti-platelet Aggregation
Quercetin can significantly inhibit the effects of cancer promoters, inhibit the growth of malignant cells in vitro, and inhibit DNA, RNA, and protein synthesis in Ehrlich ascites carcinoma cells.
Quercetin inhibits platelet aggregation and the release of serotonin (5-HT).
3.Antioxidant
Quercetin's antioxidant capacity is 50 times that of vitamin E and 20 times that of vitamin C.
It scavenges free radicals in three ways:
1) Directly;
2) Through free radical-scavenging enzymes;
3) Inhibiting free radical production;
