Liang Di Tang is a 6-ingredient Chinese Medicine formula with Unprepared Rehmannia (Di Huang) as a principal ingredient.

Invented in 1826 AD, it belongs to the category of formulas that nourish Yin and tonify. Its main actions are: 1) nourishes Yin and 2) cools Blood.

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 Liang Di Tang is used by TCM practitioners to fight patterns like Heat in the Blood, Kidney Yin Deficiency or Kidney Deficiency. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as early menstruation, abnormal uterine bleeding or prolonged periods for instance.

On this page, after a detailed description of each of the six ingredients in Liang Di Tang, we review the patterns and conditions that Liang Di Tang helps treat.

Conditions and patterns for which Liang Di 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 Liang Di Tang is used by TCM practitioners to treat four 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:

Early menstruation Abnormal uterine bleeding Prolonged periods Intermenstrual bleeding

Again it wouldn't be correct to say "Liang Di Tang treats early menstruation" for instance. Rather, Liang Di Tang is used to treat patterns that are sometimes the root cause behind early menstruation.

Now let's look at the four patterns commonly treated with Liang Di Tang.
