1, which helps to delay aging.

Tea polyphenols have strong oxidation resistance and physiological activity, and are scavengers of human free radicals. According to the research of relevant departments, the effect of 1 mg tea polyphenols on eliminating excessive free radicals harmful to human body is equivalent to 9 micrograms of superoxide dismutase (SOD), which is much higher than other similar substances. Tea polyphenols can block lipid peroxidation and remove active enzymes.

2, help to inhibit cardiovascular disease.

Tea polyphenols play an important role in human fat metabolism. The human body has cardiovascular diseases such as high cholesterol and triglycerides, such as fat deposition on the inner wall of blood vessels and atherosclerotic plaques formed after vascular smooth muscle cells proliferate. Tea polyphenols, especially catechins ECG and EGC in tea polyphenols and its oxidation products theaflavins, are helpful to inhibit this mottled proliferation, reduce the formation of fibrinogen that enhances coagulation viscosity, make coagulation clear, and thus inhibit atherosclerosis.

3. It is helpful to prevent and treat radiation injury.

Tea polyphenols and their oxidation products have the ability to absorb the toxicity of radioactive substances strontium 90 and cobalt 60. According to the clinical trials of relevant medical departments, the treatment of mild radiation sickness caused by radiotherapy with tea extract can reach more than 90%. For cytopenia, the effective rate of tea extract is 865438 0.7%; It has a good therapeutic effect on leukopenia caused by radiation.

4, help to inhibit and resist viruses and bacteria.

Tea polyphenols have strong convergence, obvious inhibition and killing effects on pathogenic bacteria and viruses, and obvious anti-inflammatory and antidiarrheal effects. Many medical units in China have used tea preparations to treat acute and chronic dysentery, amebic dysentery and influenza, and the cure rate is about 90%.

5, contribute to beauty and skin care

Tea polyphenols are water-soluble substances, which can remove facial greasy, astringe pores, sterilize and disinfect, resist skin aging, and reduce the damage of ultraviolet rays in the sun to the skin.

6, help to refresh yourself

Caffeine in tea can stimulate the central nervous system of human body, enhance the excitement process of cerebral cortex, and has the functions of refreshing the brain, clearing away heart fire and calming the nerves.

7, help diuresis to relieve fatigue

Caffeine in tea can stimulate the kidney, promote the rapid excretion of urine, improve the filtration rate of the kidney and reduce the retention time of harmful substances in the kidney. Caffeine can also eliminate excessive lactic acid in urine, which helps to eliminate fatigue as soon as possible.

8, help reduce blood fat and help digestion.

Tea helps digestion and reduce fat, which is to help "lose weight" in modern language. This is because caffeine in tea can increase the secretion of gastric juice, help digestion and enhance the ability to decompose fat. The so-called "long-term eating makes people thin" is here.
