Pu'er tea or Bolay tea is a rich full bodied tea with an earthy taste. Much like wine, Pu'er is fermented thus older tea is often more valuable than more recent vintages. Usually sold in cakes, the Chineses have a saying, "Rich men drink green tea, Gentlemen drink Pu'er." This type of tea made from a "large leaf" variety of the tea plant (Camellia sinensis) and named after Pu'er county in Yunnan, China.
Tea has a long history of medical benefits, first noticed in ancient times, and continuing to be discovered today.
Currently over 450 chemical substances have been discovered in tea, some of which are microelements capable of supplementing nutrient substances needed by the body and some other microelements can prevent or cure disease.
