Thank you for your responses to the recent article (October 2009) on Wu Shi Cha. To answer some of the questions you sent us, we have provided some more specific information we researched in our numerous books about the history of cha (tea) in China.
Wu Shi Cha is a common patent pill/extract that varies in formulation, depending upon the manufacturer, and labeled under different formula names. Wu Shi Cha has several distinct characteristics. Hong cha (red/black tea) is the main herb in the formula. The formula is complex and consists of many herbs, as seen in the table. It is aromatic, tonifies and warms the spleen, resolves dampness, and spreads and regulates qi (wei qi in particular). Noontime is the best time of day to cook the herbs for the tea. This is why the name translates as Noontime Tea Extract. Wu Shi Cha was originally found in historical TCM texts, more than 500 years ago.
