Key TCM Concepts

Yin Chen Hao Tang is a 3-ingredient Chinese Medicine formula with Virgate Wormwood (Yin Chen) as a principal ingredient.

 

Invented in 220 AD, it belongs to the category of formulas that clear Heat and expel dampness. Its main actions are: 1) clears heat and 2) resolves dampness.

 

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 Yin Chen Hao Tang is used by TCM practitioners to fight patterns like Damp-Heat in the Liver, Damp-Heat in the Gallbladder or Damp-Heat. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as viral hepatitis, cirrhosis or hepatic atrophy for instance.
