Green tea, rich in epigallocatechin gallate (EGCG), inhibits HIV virus binding and is used as a complementary therapy for HIV patients. Its high content of oxalate also inhibits HIV and other infections by using the free iron and chelating zinc, a crucial nutrient for HIV. The polyphenols in green tea are effective in preventing intestinal inflammation or IBD. Black Tea Drinking black tea lowers stress hormone levels.
