Islamabad: Green tea extract has been found effective in preventing oral cancer. Green tea is rich in polyphenols, which have been known to inhibit carcinogenesis in preclinical models, Health News reported.
“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,” researcher said.
“The extract’s lack of toxicity is attractive 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.
During the study, 41 oral leukoplakia patients were randomized to receive either green tea extract or placebo.
“Collecting oral tissue biopsies 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 to anti-angiogenic effects as a potential mechanism of action,” researcher said.
