According to the studies of relevant departments, it has been proved that the scavenging effect of 1 mg tea polyphenols on excessive free radicals harmful to human body is equivalent to 9 micrograms of superoxide dismutase (SOD), which is much higher than that of other similar substances. Tea polyphenols can block lipid peroxidation and scavenge active enzymes. According to the results of Japan's Okuda Tuoyong test, it is proved that the anti-aging effect of tea polyphenols is 18 times stronger than that of vitamin E.

Tea polyphenols play an important role in human fat metabolism. Human body has high contents of cholesterol and triglyceride, vascular inner wall fat deposition, vascular smooth muscle cell proliferation to form atherosclerotic plaques and other cardiovascular diseases. Tea polyphenols, especially catechins ECG and EGC in tea polyphenols and their oxidation products such as theaflavins, help to inhibit this plaque hyperplasia, reduce fibrinogen, which forms increased blood coagulation viscosity, and clear blood coagulation, thus inhibiting atherosclerosis.

3. Help to prevent and fight cancer

Tea polyphenols can block the synthesis of ammonium nitrite and other carcinogens in vivo, and can directly kill cancer cells and improve body immunity. According to relevant data, tea polyphenols (mainly catechins) in tea are beneficial to the prevention and adjuvant treatment of gastric cancer, colorectal cancer and other cancers.

4. Help to prevent and treat radiation injury

Tea polyphenols and their oxidation products have the ability to absorb the toxicity of strontium 90 and cobalt 60. According to the clinical trials of relevant medical departments, the effective rate of mild radiation sickness caused by tumor patients in the course of radiotherapy can reach more than 90% with tea extract; for hemocytopenia, the effective rate of tea extract is 81.7%. The therapeutic effect is better for leukopenia caused by radiation.

5. Help to restrain and resist virus.

7. Help to refresh the brain

The caffeine in tea can excite the central nervous system of the human body, enhance the excited process of the cerebral cortex, and play a refreshing and heart-clearing effect.

8. Help to diuresis and relieve fatigue

The caffeine in tea can stimulate the kidney, promote the rapid excretion of urine from the body, increase the filtration rate of the kidney, and reduce the retention time of harmful substances in the kidney. Caffeine can also eliminate excess lactic acid in urine, helping to eliminate fatigue as soon as possible.

9. Help to lower blood fat and aid digestion

Tea has an important effect on digestion and reducing fat. In today's fashion language, it helps to "lose weight".
