Lowers Stress Hormone Levels

According to a study by UCLA researchers, drinking black tea lowers stress hormone levels. Just 50 minutes after a high stress event, tea drinkers, who had been drinking 4 cups of black tea daily for a month, had a 20% greater drop in cortisol than the placebo group. Blood platelet activation, which is linked to blood clotting and the risk of heart attacks was also lower for tea drinkers.
