Tea the second most consumed beverage in the world, behind water, has been used for thousands of years. Throughout history, tea has been believed to help "purify the body" and "preserve the mind." Over the past several decades, thousands of published studies in leading medical journals have provided the proof to support tea's ancient health claims.
Tea containing hundreds, if not thousands, of bioactive compounds, including amino acids, caffeine, lignins, proteins, xanthines and flavonoids. Tea flavonoids and the related polyphenols account for more than one-third of the weight of tea leaves; the health benefits of tea are most often attributed to tea flavonoids.
Tea flavonoids are bioactive compounds that have specific cellular targets that are related to the cardiovascular, chemopreventive, metabolic, neuro-protective and other heath benefits. Recent research has explored the potential health attributes of tea through human clinical trials, population-based studies, and in vitro laboratory research.
Additional research suggests tea flavonoids and related bioactive compounds in tea may play important roles in various areas of health and may operate through a number of different mechanisms still being explored.
