Tea

Tea refers to the agricultural product of the leaves, leaf buds, and internodes of Camellia sinensis, prepared and cured by various methods. "Tea" also refers to the aromatic beverage prepared from such cured leaves by combination with hot or boiling water and the colloquial name for the Camellia sinensis plant itself.
Tea is the most widely-consumed beverage after water. It has a cooling, slightly bitter, astringent flavour.
The five types of tea most commonly found on the market are black tea, oolong tea, green tea, white tea, and pu-erh tea.
The term "herbal tea" usually refers to an infusion or tisane of fruit or herbs that contains no Camellia sinensis. The term "red tea" refers to an infusion made from the rooibos plant, also containing no Camellia sinensis.
