CORRECTION: Thanks to Darryl’s eagle eyes, I realized my analysis of the in vitro data was off by three orders of magnitude. This suggests that the powerful clinical effect of green tea on prostate cancer isn’t a direct effect, since the concentrations of at least one green tea compound within the prostate tissue wouldn’t be high enough to suppress cancer growth, at least in a petri dish.

Green tea is actually put to the test in cancer patients in my next video, Treating Prostate Cancer with Green Tea (http://nutritionfacts.org/video/treating-prostate-cancer-with-green-tea).
