Tea is an aromatic beverage prepared by pouring hot or boiling water over
cured or fresh leaves of Camellia sinensis, an evergreen shrub native to
East Asia which probably originated in the borderlands of southwestern
China and northern Myanmar. 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.
