Tea is a beverage which is drank by the people of Asia. Tea is made by boiling tea leaves in water. It has a very nice flavour. Tea is also rarely made from the leaves of Camellia taliensis. After plain water, tea is the most widely consumed drink in the world. There are many different types of tea; some have a cooling, slightly bitter, and astringent flavour, while others have vastly different profiles that include sweet, nutty, floral, or grassy notes. Tea has a stimulating effect in humans primarily due to its caffeine content.
