Tea (Carmelia sinensis) is the most consumed beverage in the world after water and has been valued since ancient times for its ability to enhance stamina, intellective activity and longevity. Tea is made into white, green, oolong or black tea based on the level of oxidation, as well as being fermented with sugar to make kombucha. Tea contains thousands of bioactive compounds including caffeine, l-theanine and polyphenols that confer hepatoprotective, neuroprotective, stress-relieving, immune-enhancing and anti-microbial effects, and human studies suggest tea may improve cognition, reduce the risk of cardiovascular disease, stroke, some cancers, diabetes, dental caries and obesity.
