The health benefits of both green and black tea were summarized byMukhtar and Ahmad (2000). Consumption of tea and its polyphenolicconstituents offers protection against skin cancer induced by either chemicalcarcinogens or ultraviolet radiation in mice. Tea consumption also providesprotection against cancers induced by chemical carcinogens that involve thelung, forestomach, esophagus, duodenum, pancreas, liver, breast, colon, andskin in mice, rats, and hamsters.
