Physiological Functions

1. Catechin has a strong effect on anti-oxidation and physiological activity. It is a well-known natural anti-oxidant with strong purging activity of free radicals. It is proved that the purging ability of health-scathing excessive free radicals by 1mg Catechin is equal to 9 μg SOD, and much stronger than other substances of the same category. Catechin also has the ability to block fat peroxidization and purge active enzyme.

2. Catechin plays an important role in human fat metabolism. Increasing cholesterol and triglyceride’s content, fat sediment in vessel and proliferation of vessel smooth muscle cell may cause cardiovascular diseases such as atherosclerosis. Catechin, especially ECG and EGC, together with its oxide Theanine can help to restrain the proliferation of the spots. It can also lower the level of fibrinogen which enhances the stickiness of blood and make coagulant products be cleared, so as to suppress the production of porridge-like substance.

3. Catechin can block the synthesis of several carcinogens such as nitrite ammonium in vivo. It can also kill cancer cells directly and enhance body immunity. It was reported that Catechin in tea leaves (mainly Catechin-deriving chemicals) could prevent and assist in therapy of various cancers such as gastric carcinoma, intestinal cancer, etc.

4. Catechin has an outstanding function on anti-radiation. It has the ability to absorb the radiation of radioactive substances such as Sc90 and Co60, preventing their diffusion into the human body, thus it was named natural UV filter. Catechin can block UV and purge the free radicals induced by UV, so as to restrain the production of melanin.

5. Catechin has a strong effect on constringency. It has obvious effect on inhibiting and killing effect to bacteria and viruses. It can inhibit and kill streptococcus, typhoid bacteria, chincough bacilli, pneumonia diplococcus, diarrhea bacilli and grape cocci, etc., inhibit or lower the toxicity of diphtheria toxin and lockjaw toxin, and resist the harm of poliomyelitis virus, flu virus, adenitis virus, exanthemata virus, bleb virus and HIV.

6. Catechin is a kind of water-soluble substance. Catechin can clean grease on face, make pores convergent and it has the effect of sanitization, sterilization, anti-skin aging, especially reducing the damage of UV to the skin in sunlight.

7. Catechins can kill lactobacillus and other decay-causing bacteria living between teeth. It has the ability to restrain the activity of glucose polymerase, then make glucose unable to polymerize on the surface of bacteria and the bacteria unable to touch the teeth, thus block the process of teeth decaying. Protein residue of food between teeth is medium of decaying bacteria proliferation. Catechin can kill this type of bacteria, so it has the function of removing halitosis.
