Key TCM Concepts

Li Zhong Wan is a 4-ingredient Chinese Medicine formula with Dried Ginger (Gan Jiang) as a principal ingredient.

 

Invented in 220 AD, it belongs to the category of formulas that warm the middle and dispel Cold. Its main actions are: 1) warms the Middle Burner and 2) strengthens the Spleen and Stomach.

 

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 Li Zhong Wan is used by TCM practitioners to fight patterns like Kidney and Spleen Yang Deficiency or Greater Yin stage. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as gastroenteritis, peptic ulcers or irritable bowel syndrome for instance.
