Key TCM Concepts

Shi Wei San is a 5-ingredient Chinese Medicine formula.

 

Invented in 1687 AD, it belongs to the category of formulas that clear Heat and expel dampness. Its main actions are: 1) clears heat and 2) promotes the resolution of 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 Shi Wei San is used by TCM practitioners to fight patterns like Damp-Cold in the Bladder. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as urethritis, cystitis or urinary stones for instance.
