Ban Xia Xie Xin Tang is a 7-ingredient Chinese Medicine formula with Goldthread Rhizomes (Huang Lian) as a principal ingredient.

Invented in 220 AD, it belongs to the category of formulas that harmonize Stomach-Intestines. Its main actions are: 1) reverses the flow of Rebellious Stomach Qi and 2) relieves both Heat and Cold Stagnation in the gastrointestinal tract.

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 Ban Xia Xie Xin Tang is used by TCM practitioners to fight patterns like Phlegm-Fluids in the Stomach and Small intestine or Phlegm-Heat in the Middle Burner. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as peptic ulcers, gastroesophageal reflux disease or gastritis for instance.

On this page, after a detailed description of each of the seven ingredients in Ban Xia Xie Xin Tang, we review the patterns and conditions that Ban Xia Xie Xin Tang helps treat.

Conditions and patterns for which Ban Xia Xie Xin Tang may be prescribed

It's important to remember that herbal formulas are meant to treat patterns, not "diseases" as understood in Western Medicine. According to Chinese Medicine patterns, which are disruptions to the body as a system, are the underlying root cause for diseases and conditions.

As such Ban Xia Xie Xin Tang is used by TCM practitioners to treat two different patterns which we describe below.

But before we delve into these patterns here is an overview of the Western conditions they're commonly associated with:

Peptic ulcers Gastroesophageal reflux disease Gastritis Chronic cholecystitis Colitis Hepatitis

Again it wouldn't be correct to say "Ban Xia Xie Xin Tang treats peptic ulcers" for instance. Rather, Ban Xia Xie Xin Tang is used to treat patterns that are sometimes the root cause behind peptic ulcers.
