Researchers at the University of Florida have proven that Green Tea Capsules fight both a cold and a flu virus very effectively. In this newly published, randomized, double-blind, placebo-controlled study healthy adults from 18 to 70 were given either an inactive placebo or a standardized Green Tea Capsule twice a day for 3 months. Among the people taking Green Tea Capsules there was a 32% drop in the number of people with cold or flu symptoms, 23% fewer illnesses that lasted at least two days, and 36% fewer days with symptoms compared to people taking placebo.
