Pharmacological Action
Broad Pharmacological Effects
Quercetin is a natural flavonoid, which have anti-tumor, anti-oxidation, anti-infection, immune suppression, cardiovascular protection and blood sugar regulation and other pharmacological effects.
Respiratory & Cardiovascular Benefits
Quercetin has a good expectorant and antitussive effect, and has a certain antiasthmatic effect, is used to treat chronic bronchitis. In addition, it also has the effects of reducing blood pressure, enhancing the resistance of capillaries, reducing the frag of capillaries, reducing blood lipid, dilating coronary artery, and increasing coronary blood flow, which has an auxiliary therapeutic effect on patients with coronary heart disease hypertension.
Liver Protection
Quercetin can prevent and treat various liver injuries, such as fatty liver, cirrhosis, and hepatic fibrosis. In recent years it has been found that Quercetin can significantly reduce the concentration of triglycerides in the serum of rats with fatty liver, inhibit the activity of aspart transaminase, and has a good effect on the treatment of fatty liver.
Product Function
Osteoporosis & Disease Prevention
Quercetin prevents and treats osteoporosis, Quercetin has been used in clinical trials and animal studies to prevent or treat a variety of diseases such as polycystic ovary syndrome (PCOS), cancer, autoimmune disorders and chronic cardiovascular disease due to its powerful antioxidant effects.
Powerful Antioxidant Effect
Antioxidant effect, the most important and basic function of Quercetin, is related to its antibacterial and anti-inflammatory, antifrotic, antitumor, hypoglycemic, and lipid-lowering effects. Free radicals can cause cell membrane lesions, gene mutations, and erode tissues of the organism, inducing various diseases of the tissues and organs of the organism. The antioxidant property of quercetin can effectively reduce or eliminate the damage caused free radicals.
Anti-tumor Properties
Anti-tumor, Quercetin can significantly inhibit the action of carcinogens, inhibit the growth of malignant cells in vitro, and inhibit the synthesis DNA, RNA and protein of ehrlich ascites tumor cells.
