Pu'er is from the Southwest China's Yunnan province and has been famous as a medicinal tea. The history of Pu'Er tea could date back to the Tang Dynasty when it was only enjoyed by  the noblemen of that time.

Pu'er tea derives its name from the market town of Pu-er, where it was originally processed and sold. In ancient time, all the tea produced in Yunnan was sold from Pu-er town to other parts of China or overseas. So Pu-er in Yunnan is just like the Ma Lian Dao in Beijing.

It is said in Qing dynasty, the transport of Pu'er tea to the Forbidden City has been delayed due to bad weather. It took more than half-year to reach the imperial palace. The emperor was very unhappy but after he tasted the "overdue" Pu'er, he found it was more fragrant. Since  the specialty of Pu'er  was discovered,  Forbidden City has stored tons of Pu'er, accounting for two thirds of all imperial tea.

Tao Cha Ju is an exclusive seller of Pu'er tea. They collect tea leaves from special broad-leaf tea trees, which are said to be related to ancient prehistoric tea trees in natural forest in Yunan. So their tea is pesticide-free and contain high natural components.
