Anotations

Scope note:

Beverage of Asian origin derived from unfermented leaves, cut and steamed, of the plant Camellia sinensis; used for many medicinal applications as well as for refreshment. ‘Black tea’ is derived from the same plant. It is produced by allowing the leaves to oxidize. In the context of conservation, green tea catechins have been used as environmentally friendly formaldehyde scavengers.
