Tea, Black

Black tea is a type of tea that is more oxidized than green, oolong, and white teas. It is made from the leaves of the plant Camellia sinensis, which undergoes full fermentation (oxidation) during processing, giving the tea its dark color and rich flavor. Black tea contains caffeine, polyphenols, and other bioactive compounds and is widely consumed as a beverage and used in functional food and supplement products for its antioxidant and stimulating properties.
