Key TCM Concepts

Yi Wei Tang is a 5-ingredient Chinese Medicine formula with Unprepared Rehmannia (Sheng Di Huang) and Dwarf Lilyturf Roots (Mai Dong) as principal ingredients.

 

Invented in 1798 AD, it belongs to the category of formulas that nourish Yin and tonify. Its main actions are: 1) strengthen the Stomach and 2) creates Body Fluids.

 

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 Yi Wei Tang is used by TCM practitioners to fight patterns like Stomach Yin Deficiency. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as chronic gastritis or diabetes for instance.
