More evidence for tea’s anticancer potential NutraIngredients 12/21/06 "Teas, both green and black, have potent anti-cancer effects against a wide range of tumours, says a new study led by the US Department of Agriculture that adds to an ever growing body of science behind the compounds...The researchers report that the majority of the catechins, theaflavins, theanine, and all the general tea extracts decreased the numbers of human breast (MCF-7), colon (HT-29), hepatoma (liver) (HepG2), and prostate (PC-3) cell lines, with the ethanol/water extracts found to contain higher levels of flavonoids and to have a higher activity" The lead author was Mendel Friedman from USDA.

Promising in vitro study but we need many more in vivo studies.
