Formula Category

Formulas that dry Dampness and transform Phlegm

Main Actions

  • Dries Damp and dispels Phlegm
  • Regulates Qi and harmonizes the Middle Burner (Stomach and Spleen)

Formula Origin

Formulary of the Pharmacy Service for Benefiting the People in the Taiping Era (1148 AD)

Formula Description

Er Chen Tang is a 5-ingredient Chinese Medicine formula with Crow-Dipper Rhizomes (Ban Xia) and Tangerine Peel (Chen Pi) as principal ingredients.

 

Invented in 1148 AD, it belongs to the category of formulas that dry Dampness and transform Phlegm. Its main actions are: 1) dries Damp and dispels Phlegm and 2) regulates Qi and harmonizes the Middle Burner (Stomach and Spleen).

 

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 Er Chen Tang is used by TCM practitioners to fight patterns like Damp-Phlegm in the Lungs, Damp-Phlegm or Phlegm-Fluids. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as morning sickness, upper respiratory tract infections or chronic bronchitis for instance.
