Formula Origin

Clinical Handbook of Chinese Medical Formulas (1950 AD)

Formula Description

Er Xian Tang is a 6-ingredient Chinese Medicine formula with Curculigo Rhizomes (Xian Mao) and Epimedium Herbs (Yin Yang Huo) as principal ingredients.

 

Invented in 1950 AD, it belongs to the category of formulas that tonify Yin and Yang. Its main actions are: 1) nourishes Yin and tonifies Yang of the Kidneys and 2) clears Empty 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 Er Xian Tang is used by TCM practitioners to fight patterns like Kidney Yang Deficiency or Deficiency of both the Kidney Yin and Yang. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as irregular menstruation, menopausal syndrome or perimenopausal syndrome for instance.
