Pu-erh tea is made from the leaves and stems of the Camellia sinensis plant. This is the same plant that is used for making green, oolong, and black teas. Though the same source plant is used, the different teas are made by using different processes. Green tea is not fermented, oolong tea is partially fermented, black tea is fully fermented, and Pu-erh tea is post-fermented. This means Pu-erh tea’s processing includes both fermentation and then prolonged storage, or “aging,” under high humidity. Pu-erh tea that is aged for a longer period of time is supposed to taste better. However, it can also smell musty or taste stale because mold and bacteria will sometimes attack the tea during the long aging process. Pu-erh tea is produced mainly in the Yunnan district in the southwestern part of China. It has also gained popularity in Taiwan. Pu-erh tea is used as medicine. Pu-erh tea is used for improving mental alertness and sharp thinking. It is also used for reducing high cholesterol.
