Green tea may counter effects of cancer drug
A study by the University of Southern California found that green tea may negate the effects of bortezomib, a drug used for treatments of certain types of blood cancer. The cancer drug, sold under the brand name Velcade, is said to be countered by green tea polyphenols, and could be entirely blocked by green tea supplements, containing up to 50 times as much polyphenol as a single cup of tea. Velcade is used to treat multiple myeloma, the second most common blood cancer.
