There are thousands of different types of tea. All tea comes from the tea plant. The leaves and buds of this plant are picked several times a year, usually by hand. After it has been picked, the tea is processed into black tea, oolong tea, green tea or white tea. Black tea was invented in China during the Ming Dynasty as a way to keep tea fresh when it was transported long distances.

This is because it contains herbs, fruits, spices②, etc., instead of leaves from the tea plant. To truly be tea, the leaves must come from this plant. ① herbal tea 药草茶 ② spice n. 香料 All tea naturally contains caffeine①, which comes from the tea leaves. Decaffeinated tea② is regular tea (usually green or black) that has been processed to remove the caffeine. In recent years, organic tea③ has become popular too.
