Green Tea Extract and Oral Cancer
Oral Cancer Prevention Advances with a Translational Trial of Green Tea. Cancer Prev Res 2009;2(11) November 2009. This perspective on Tsao et al. (beginning on p. 931 in this issue of the journal) discusses green tea extract, which was shown for the first time to have dose-dependent effects in a clinical chemopreventive setting (oral premalignant lesions). This translational trial provides important data on angiogenesis and other biomarkers on which to base future clinical research, which should include trials of green tea extract or polyphenols combined with other natural or synthetic compounds to enhance chemopreventive effects.
“Consuming beverages enhanced with green tea extract provides a protective effect against oral cancer according to this study published in November of 2009. The ability of EGCG to kill harmul viruses and bacteria continues to be explored. The chemoprotective effects of EGCG from a green tea extract provide substantial benefit for multiple reasons. This study investigated the benefit of drinking green tea enhanced beverages versus taking a pill or small concentrated dose.” – Josh Smith
