Tea family (Theaceae)
Description
Camellia sinensis is an evergreen shrub or small tree with leathery, glossy dark-green, serrated leaves. All true teas (green, black, white, oolong) come from this species; the differences arise from how the leaves are processed. The leaves contain caffeine as well as polyphenols, especially catechins. As a beverage, tea is consumed worldwide and has been used for centuries.
