I. Anti-aging Effect of Tieguanyin Some scientific studies at home and abroad show that human aging is related to the peroxidation of unsaturated fatty acids in the body, and the peroxidation of unsaturated fatty acids is related to the action of free radicals. Free radicals with high chemical activity can make unsaturated fatty acids over-oxidized, make cell function mutate or decline, cause tissue proliferation and necrosis, and produce fatal diseases. Lipid peroxidation is the devil of human health, but the culprit is free radicals. As long as free radicals are removed, cells can grow and develop normally, and live a long and healthy life. Commonly used antioxidants are vitamin C and vitamin E, which can effectively prevent the over-oxidation of unsaturated fatty acids. Recently, Japanese researchers have shown that polyphenols in Tieguanyin can prevent excessive oxidation; Purine alkaloids can indirectly scavenge free radicals, thus achieving the purpose of delaying aging.

Second, the anti-cancer effect of Tieguanyin Cancer is an "incurable disease" that seriously threatens people's health today. Therefore, in recent years, the anti-cancer research of tea has aroused great interest and concern. A few years ago, it was reported that the esophageal cancer of Shanghai residents decreased year by year because of drinking tea, so the fact that drinking tea can prevent cancer caused great repercussions all over the world. Nowadays, drinking tea to prevent cancer has been recognized by the world, and Tieguanyin is the best anticancer effect in tea. As early as 1983, Professor Tuonan Okuda of Okayama University in Japan had screened out the anticancer effects of dozens of plant polyphenols. The results showed that catechin (EGCG) had strong anticancer activity. Another scientist believes that Tieguanyin tea polyphenols are the main active ingredient in the study of confirming Tieguanyin's anti-mutation. In the study of chemical carcinogenesis, the preventive effect of Tieguanyin tea polyphenols has been affirmed. In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of nitrosamines, which plays a great role in the prevention and treatment of cancer.
