Tea
originated in Southwest China, where it was used as a medicinal drink. It was
popularized as a recreational drink during the Chinese Tang dynasty, and tea
drinking spread to other East Asian countries. Portuguese priests and merchants
introduced it to Europe during the 16th century. During the 17th century,
drinking tea became fashionable among Britons, who started large-scale
production and commercialization of the plant in India. Combined, China and
India supplied 62% of the world's tea in 2016.
The term
herbal tea refers to drinks not made from Camellia sinensis: infusions of
fruit, leaves, or other parts of the plant, such as steeps of rosehip,
chamomile, or rooibos. These are sometimes called tisanes or herbal infusions
to prevent confusion with tea made from the tea plant.
- The fresh young, light greens leaves contain about 4% caffeine and are harvested for tea production.
- The leaves are steamed and dried for green tea, or fermented and dried for black tea.
- For ordinary home use the leaves are infused in hot water and used as the drink that is commonly known as tea.
- Cold tea can be used as a soaking liquid to flavour dried fruit and ham.
- Leaf extracts are fermented to make kombucha.
- The seeds of Camellia sinensis can be pressed to yield tea oil, a sweetish seasoning and cooking oil.
