Tea is an aromatic beverage commonly prepared by pouring hot or boiling water over cured leaves of the tea plant, Camellia sinensis. After water, tea is the most widely consumed beverage in the world. It has a cooling, slightly bitter, and astringent flavour that many people enjoy. Tea likely originated in China during the Shang Dynasty as a medicinal drink. Tea was first introduced to Portuguese priests and merchants in China during the 16th century.
