Formulas that harmonize Liver-Spleen

Main Actions

  • Regulates Liver and Spleen
  • Eliminates Internal Heat

Formula Origin

Discussion of Cold Damage (220 AD)

Formula Description

Si Ni San is a 4-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 Liver-Spleen. Its main actions are: 1) regulates Liver and Spleen and 2) eliminates Internal Heat.

 

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 Si Ni San is used by TCM practitioners to fight patterns like Rebellious Qi, Phlegm in Kidneys or Gallbladder or Rebellious Liver Qi. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as cholecystitis, cholelithiasis or gastritis for instance.
