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.
