The average blocking rate is over 82%, while black tea is only 43%.

It has a strong inhibitory effect on the benzopyrene inducer of the chemical carcinogen and can also inhibit the activity of aryl hydrocarbon receptor molecules (such as aryl groups). Hydrocarbon receptors, induced by dioxin pollutants and some carcinogens in cigarettes, can cause certain harmful genes in the organism to “turn on” and cause canceration), which can block the generation of certain carcinogens and kill cancer cells and inhibit cancer cell growth. “The unique biochemical characteristics make green tea’s protective effect spread to many different cells so that it has obvious effects on a variety of carcinogens related to human tumors including baicalin, high-temperature lysates of amino acids, and DNA damage.
