Organ Affinity Gallbladder, Liver
Parts Used Dried root and rhizome
Role in Xiao Chai Hu Tang
Chai Hu is the most important herb for solving Lesser Yang-Warp disorders in the Chinese materia medica. Combined with the deputy herb, Baikal skullcap root (Huang Qin), which drains Heat from the Liver and Gallbladder (the Interior aspect of the Lesser Yang-Warp), it vents the pathogenic influence and thereby releases Lesser Yang-Warp disorders. It also spreads the Liver Qi with an ascending, cooling action (contrary to most cooling herbs, which cause things to descend). This combination thereby clears the Heat without causing it to sink deeper into the body.

Discussion of Cold Damage (220 AD)

Formula Description

Xiao Chai Hu Tang is a 7-ingredient Chinese Medicine formula with Bupleurum Roots (Chai Hu) as a principal ingredient.

 

Invented in 220 AD, it belongs to the category of formulas that harmonize lesser Yang-warp disorders. Its main actions are: 1) treats the Lesser Yang Channels (Gallbladder and Triple Warmer) and 2) regulates the Liver and Spleen functions.

 

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 Xiao Chai Hu Tang is used by TCM practitioners to fight patterns like Phlegm-Fluids in the Stomach and Small intestine, Lesser Yang stage or Half Exterior Half Interior. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as hepatitis, chronic cholecystitis or chronic gastritis for instance.
