The efficacy and function of Scutellaria baicalensis Scutellaria baicalensis has the effect of clearing heat and drying dampness, diarrhea, detoxification, etc., and its pharmacological effects: 1 a. Antioxidant Scutellaria baicalin, the main active ingredient of baicalin, baicalein can scavenge hydroxyl radicals, alkyl free radicals, inhibit the mitochondrial lipid peroxidation caused by the resulting lipid metabolism and phospholipids, and fight against hydrogen peroxide-induced cell damage, myocardial ischemia and reperfusion has a protective effect. Anti-cancer effects Baicalein can inhibit aflatoxin B1 and nitrosoguanidine on the mutagenic effect of Salmonella, can reduce the frequency of chromosomal aberrations caused by aflatoxin, but also enhance the cancer inhibition of cellular mediators such as interleukin and tumor necrosis factor. Third, antiviral and antibacterial effects Baicalin can inhibit T-cells and HIV at concentrations lower than cytotoxicity, and can prevent the replication of HIV-1 at the beginning of its adsorption by cells. It has been proved that the main action link of baicalin lies in interfering with HIV-1 attacking target cells, so it is expected to be developed as a new anti-AIDS drug. Baicalin also has an inhibitory effect on the pathogenic fungi of skin and nails. Fourth, the role of blood vessels Low concentrations of baicalein on isolated mesenteric arteries show contraction, high concentrations show relaxation of vascular smooth muscle effect. Sanhuang diarrhea heart soup and Huanglian detoxification soup have a strong killing effect on trypanosomes that cause sleeping sickness
