A large number of modern scientific researches have confirmed that tea does contain some biochemical components which are closely related with human health. Tea can not only refresh the spirit, clear away summer heat, help digestion and weight loss, but also has some pharmacological effect on some modern diseases, such as radiation, cardiovascular diseases, cancer and other diseases. The pharmacological effect of tea mainly comes from tea polyphenol, caffeine, lipopolysaccharide, theanine, and so on. In detail:

First, anti-aging
Tea can help delay the aging process. Tea polyphenol has a strong antioxidant property and biological activity, so it is a scavenger of free radicals in human body. According to the research by relevant department, it is proved that the effect of 1 mg of tea polyphenol to clear the excessive free radicals in human body is equivalent to that of 9 microgram superoxide dismutase (SOD), and it is significantly higher than any other similar substances. Tea polyphenol can block the lipid peroxidation and scavenge the active enzymes. Test results have confirmed that the anti-aging effect of tea polyphenol is 18 times higher than that of vitamin E 18.

Second, inhibition of cardiovascular disease
Tea is helpful to inhibit cardiovascular disease. Tea polyphenol plays an importance part in the fat metabolism of human body. Tea polyphenol, especially catechin and theaflavin contained in tea polyphenol, can help inhibit the proliferation of maculosus, so that to reduce the fibrinogen, clear the clotting, thus suppressing atherosclerosis.

Third, anti-cancer
Tea can help prevent cancer. Tea polyphenol may block the synthesis of many carcinogenic substances in the body, such as ammonium nitrate. And it also has the effect of directly killing cancer cells and improving body immunity. According to relevant statistics, tea polyphenol (mainly catechins compounds), is conducive to the prevention and adjuvant treatment of many cancer diseases, such as gastric cancer, colon cancer and so on.

Fourth, radiation protection
Tea is conducive to the prevention and treatment of radiation injuries. Tea polyphenol and its oxidation products have the ability of absorbing the harms of some radioactive materials. According to the clinical trials of relevant medical department, for the mild radiation sickness caused in the course of radiation therapy, the treatment efficiency of tea is up to 90%.

From the various effects of tea, we can easily see its great importance to human health. As a result, try to drink more tea in daily life, so as to make yourself away from some diseases.
