Anderson Cancer Center study experienced a clinical response to the green tea extracts, according to findings published in Cancer Prevention Research. “While still very early, and not definitive proof that green tea is an effective preventive agent, these results certainly encourage more study for patients at highest risk for oral cancer,” explained the research team. “The extract’s lack of toxicity is very crucial in prevention trials. It’s very important to remember that these are otherwise healthy individuals and we need to ensure that agents studied produce no harm,” they added. Green tea contains between 30 and 40 per cent of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3 and 10 per cent. Oolong tea is semi-fermented tea and is somewhere between green and black tea. The four primary polyphenols found in fresh tealeaves are epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), and epicatechin (EC). The study followed 41 people with oral leukoplakia, a condition is a sign of oral cancer risk. The participants were assigned to receive either placebo or green tea extract at one of three doses, including 500 milligrams or 1,000 mg three times a day. The researchers collected oral tissue biopsies, which they say was “essential in that it allowed us to learn that not only did the green tea extract appear to have benefit for some patients, but we pointed [...]
