Qing Wen Bai Du Yin is a 14-ingredient Chinese Medicine formula with Gypsum (Shi Gao) and Anemarrhena Rhizomes (Zhi Mu) as principal ingredients.

Invented in 1794 AD, it belongs to the category of formulas that clear Heat and resolve toxicity. Its main actions are: 1) drains Fire and 2) resolves Toxicity.

In Chinese Medicine health conditions are thought to arise due to "disharmonies" in the body as a system. These disharmonies are called "patterns" and the very purpose of herbal formulas is to fight them in order to restore the body's harmony.

From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as meningitis, encephalitis b or measles encephalitis for instance.

On this page, after a detailed description of each of the fourteen ingredients in Qing Wen Bai Du Yin, we review the patterns and conditions that Qing Wen Bai Du Yin helps treat.
