Camellia sinensis is a species of evergreen shrub or small tree whose leaves and leaf buds are used to produce tea. It is of the genus Camellia of flowering plants in the family Theaceae. Common names include “tea plant”, “tea shrub”, and “tea tree”. Green tea (Camellia Sinensis) is a plant frequently steeped in hot water and drunk as tea. It exerts most of its benefits through water-soluble polyphenols (frequently referred to as catechins) extracted from the leaves, into water, which is then consumed.
