Key TCM Concepts

Wu Mei Wan is a 10-ingredient Chinese Medicine formula with Chinese Plums (Wu Mei) as a principal ingredient.

 

Invented in 220 AD, it belongs to the category of formulas that expel parasites. Its main actions are: 1) warms the Organs and 2) drains Heat.

 

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.

 

In this case Wu Mei Wan is used by TCM practitioners to fight patterns like Terminal Yin stage or Intestinal Parasite. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as ascariasis, biliary ascariasis or hookworm for instance.
