Tea polyphenols have strong antioxidant properties and physiological activity, and are scavengers of free radicals in the human body. According to the relevant departments of the research proved that 1 mg of tea polyphenols to remove harmful excess free radicals in the human body is equivalent to the efficacy of 9 micrograms of superoxide dismutase (SOD), much higher than other similar substances. Tea polyphenols have the effect of blocking lipid peroxidation and removing active enzymes. According to the results of the Japanese Okuda Toyo test, confirmed that the anti-aging effect of tea polyphenols than vitamin E 18 times stronger.
2, help inhibit cardiovascular disease
Tea polyphenols have an important role in human fat metabolism. The body's cholesterol, triglycerides and other high levels of fat deposits in the lining of blood vessels, vascular smooth muscle cell proliferation after the formation of atherosclerotic plaques and other cardiovascular diseases. Tea polyphenols, especially tea polyphenols in the catechins ECG and EGC and its oxidation products such as theaflavin, help to make this plaque proliferation is inhibited, so that the formation of blood coagulation viscosity enhancement of fibrinogen is reduced, coagulation becomes clearer, thus inhibiting atherosclerosis.
3, help prevent and fight cancer
Tea polyphenols can block ammonium nitrite and other carcinogens synthesized in the body, and has the effect of directly killing cancer cells and improve the body's immune system. According to relevant information, tea polyphenols in tea (mainly catechin compounds), stomach cancer, intestinal cancer and other types of cancer prevention and adjuvant therapy, are beneficial.
4, to help prevent and treat radiation damage
Tea polyphenols and their oxidation products have the ability to absorb the radioactive material strontium 90 and cobalt 60 poisoning. According to the relevant medical department clinical trials have confirmed that the tumor patients in the process of radiation therapy caused by mild radiation sickness, tea extract for treatment, the efficiency can reach more than 90%; on the hematopenia, tea extract treatment efficiency of 81.7%; due to radiation radiation caused by leukopenia treatment effect is better.
5, help inhibit and resist viruses bacteria
Tea polyphenols have a strong astringent effect on pathogenic bacteria, viruses have obvious inhibitory and killing effect, anti-inflammatory and anti-diarrhea have obvious effects. China has a number of medical units apply tea preparations for the treatment of acute and chronic dysentery, amoebic dysentery, influenza, the cure rate of about 90%.
6, help beauty and skin care
Tea polyphenol is a water-soluble substances, wash your face with it can remove facial grease, astringent pores, with disinfection, sterilization, anti-aging skin, reduce ultraviolet radiation in the sun on the skin damage and other effects.
7, helps to wake up and refresh
The caffeine in the tea can prompt the body's central nervous system, enhance the cerebral cortex of the excitation process, play a refreshing, refreshing, clearing the mind of the effect.
8, help diuretic
The caffeine in tea can stimulate the kidneys, prompting the rapid discharge of urine, improve the filtration rate of the kidneys, reduce the retention of harmful substances in the kidneys. Caffeine can also eliminate excess lactic acid in the urine, which helps the body eliminate fatigue as soon as possible.
9, help lower fat digestion
Tang Dynasty "herb gleanings" in the efficacy of tea, "eating for a long time makes people thin" records. China's border ethnic minorities have "not a day without tea" said. Because tea has the important effect of digestion and reduce fat, with today's fashion language, is to help "lose weight".

This is the reason why the so-called "long time to eat people thin" is here.
The tea is a small tree, 5 meters high, 38 cm in diameter, the shoots are glabrous or sparsely hairy. Leaves thin leathery, elliptic or oblong, 10-15 centimeters long, 4-7 centimeters wide, apex obtuse or acuminate, base cuneate, dark green above when dry, brownish green below, glabrous.
The big tree tea grows in the woods, surrounded by tall trees for shade, creating diffused light. The tea tree is shade-tolerant plants, in the shade conditions, the tea tree leaf folding can be reduced or no folding, branches open outward into a horizontal shape, the leaf surface amplitude increased and bulging, the leaf color becomes darker and more glossy, the aromatic substances in the leaves increased, the crude fiber content is reduced, the tenderness persistent, polyphenolic compounds without too much or too little shortcomings, the fresh leaves within a variety of ingredients rich and coordinated, so that the tea soup flavor is mellow, reduce the bitterness and astringency, aroma and flavorful.
