| introduction | puerarin, also known as puerarin flavone, is a natural isoflavone carbon glycoside and is the key ingredient for puerarin to exert its medicinal effect. Puerarin has the effects of lowering blood sugar, regulating blood lipids, protecting blood vessels, resisting oxidative stress, resisting infection, improving insulin sensitivity index, etc., and has fewer adverse reactions. It is known as "phytoestrogen" and is clinically used to treat cardiovascular and cerebrovascular diseases, cancer, Parkinson's disease, Alzheimer's disease, diabetes and diabetes complications. |
| uses | pueraria root crude extract and puerarin have regulatory effects on proliferation inhibition, apoptosis induction and cell cycle of liver cancer cell SMMC-7721, and can inhibit its growth to varying degrees, and pueraria root crude extract can promote apoptosis of SMMC-7721 cells. Puerarin can promote the proliferation of human T lymphocytes γδT and increase its killing activity, while the proliferation of γδT cells may be related to the Bcl-2 expression of puerarin-activated P-ERKl/2 signaling pathway and anti-apoptotic protein, and the improvement of γδT cell SMMC-7721 killing activity on hepatocellular carcinoma cells may be related to the expression of granzyme B, perforin and CD107a in γδT cells. [Pharmacological effects] can be used for adjuvant treatment of coronary heart disease, angina pectoris, myocardial infarction, retinal artery and vein occlusion, sudden deafness and ischemic cerebrovascular disease, viral myocarditis in children, diabetes, etc. Effects on the cardiovascular system |
| pharmacological action | kudzu root is the PuerariathomsoniiBenth of leguminous plant kudzu vine (kudzu kudzu). Or Puerarialobata(Willd.)Ohwi. The root. Sweet, pungent, cool in nature. Return to spleen, stomach and lung meridian. It has the effects of relieving muscle and deheating, penetrating rash, promoting body fluid and quenching thirst, promoting yang and stopping diarrhea, dredging meridians and activating collaterals, and relieving alcohol and poison. It is often used in exogenous headache, fever, neck back pain, measles impermeability, thirst, thirst, heat dysentery, diarrhea, dizziness, headache, stroke, hemiplegia, chest pain, and alcohol injury. Pueraria lobata contains a variety of effective ingredients, mainly puerarin. Puerarin Chinese alias 8-beta-D-grape pyranose -4 ', 7-dihydroxyisoflavone. Modern studies have shown that puerarin has a good effect on sudden deafness and cardiovascular and cerebrovascular diseases. Used to dilate blood vessels and improve blood circulation; reduce myocardial oxygen consumption and inhibit cancer cells; increase coronary flow and adjust blood microcirculation; treat sudden deafness at all ages; reduce the risk of cardiovascular and cerebrovascular diseases. As people conduct in-depth research on the pharmacological effects of Pueraria lobata, various foods and drugs processed as raw materials are widely praised by people at home and abroad. puerarin can remove free radicals in the body to varying degrees, reduce lipid peroxidation damage, and improve the activities of antioxidant enzymes in the body, such as SOD, glutathione peroxidase and catalase. puerarin can improve immunity, improve microcirculation, expand blood vessels, increase coronary flow, reduce blood pressure, slow down heart rhythm and reduce myocardial oxygen consumption without obvious negative inotropic effects. It also has the effects of anti-thrombosis, improving high-density lipoprotein, anti-vasospasm and reducing platelet accumulation. |
| treatment of diabetes | puerarin can treat diabetes by lowering blood sugar concentration. puerarin can up-regulate insulin receptor substrate IRS-1 and insulin-like growth factor IGF-1 protein, and at the same time promote the expression of insulin receptor InsR and peroxisome proliferator activated receptor PPARα, thus achieving the purpose of reducing blood sugar and treating diabetes. In addition, puerarin can also inhibit the activity of α-glucosidase, thereby reducing blood sugar concentration and achieving the purpose of treating diabetes. Studies have found that puerarin drugs can improve the body's sensitivity to insulin in patients with type 2 diabetes. Puerarin drugs can weaken insulin resistance and treat diabetes. Puerarin can also inhibit the production of TNF-α in plasma, improve the body's sensitivity to insulin levels, and reduce blood sugar levels. In addition, the application of puerarin in diabetic retinopathy can help reduce the blood flow resistance of the ophthalmic artery, accelerate the blood flow speed, promote the expansion of the muscle artery, and reduce local thrombosis, which has a preventive effect on diabetic retinopathy. Puerarin also has a therapeutic effect on gestational diabetes. |
