Black tea
At the University College in London, a stressful task was given to two groups of students. While one group did the task along with drinking tea, the other did the same task while drinking normal tea. It was noticed that the group of students who did the task while drinking black tea got their stress level or cortisol level dropped by 47% in an hour’s time after the completion of the task. On the other hand, the group of students who consumed normal tea in place of black tea experienced a loss of 27% in their cortisol level after the an hour of the completion of the task. It was later mentioned by the experts that this calming effect was due to the natural chemicals flavonoids and polyphenol in tea.
