Regulating blood lipids

Tea polyphenols can comprehensively regulate blood lipids, especially by reducing the levels of serum triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C), and increasing high-density lipoprotein. In addition, tea polyphenols are strong inhibitors of LDL oxidation, which can effectively inhibit the oxidative modification of LDL and have a certain inhibitory effect on the factors affecting the formation of atherosclerosis.

Antiviral and antibacterial

Tea polyphenols, as a broad-spectrum, potent, and low toxicity antibacterial drug, have been recognized by scholars in many countries around the world. In numerous antibacterial tests, it has been found that it has varying degrees of inhibitory and killing effects on many pathogenic bacteria, especially intestinal pathogenic bacteria, such as Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus mutans, Clostridium botulinum, Lactobacillus, Vibrio cholerae, and oral streptococci. At the same time, it can effectively prevent antibiotic resistant Staphylococcus infections and has inhibitory activity against hemolysin. In addition, tea polyphenols also have strong inhibitory effects on pathogenic fungi that can cause skin diseases in the human body, such as white ringworm, spotted blister white ringworm, sweat blister white ringworm, and stubborn ringworm. Tea polyphenols can also have a protective effect on beneficial bacteria in the intestine.

Anti tumor

Tea polyphenols exhibit anti mutagenic effects in vitro and can inhibit skin, lung, anterior stomach, esophagus, pancreas, prostate, duodenum, colon, and rectal tumors caused by carcinogens in rodents. The main mechanisms by which tea polyphenols inhibit tumors are as follows: antioxidant and free radical scavenging; Block the formation of carcinogens and inhibit metabolic transformation in the body. Tea polyphenols can block the synthesis of highly carcinogenic nitrosamines in the body, further inhibiting the carcinogenic effects of nitrosamines; Inhibiting the activity of enzymes that promote cancer, such as inhibiting telomerase activity to achieve its anti-cancer activity; Enhance the body's immune system; The reversal effect of multidrug resistance in tumor cells; The impact on the opening of PT channels (mitochondrial permeability change channels). It is speculated that tea polyphenols may directly act on the protein components of PT pores, thereby regulating mitochondrial permeability and altering pore opening, protecting mitochondria from damage; Inhibit the biosynthesis of tumor cell DNA. Tea polyphenols can induce DNA double band breaks in tumor cells, showing a positive correlation between tea polyphenol concentration and the degree of DNA double band breaks. Therefore, it can inhibit the synthesis of DNA in tumor cells, further suppressing the growth and proliferation of tumors.
