Zhi Bo Di Huang Wan is a 8-ingredient Chinese Medicine formula with Anemarrhena Rhizomes (Zhi Mu), Phellodendron Bark (Huang Bo) and Prepared Rehmannia (Shu Di huang) as principal ingredients.
Invented in 1584 AD, it belongs to the category of formulas that nourish Yin and tonify. Its main actions are: 1) tonifies Yin and 2) drains Fire.
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 Zhi Bo Di Huang Wan is used by TCM practitioners to fight patterns like Kidney and Liver Yin Deficiency. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as vaginal itching for instance.
On this page, after a detailed description of each of the eight ingredients in Zhi Bo Di Huang Wan, we review the patterns and conditions that Zhi Bo Di Huang Wan helps treat.

Poria-cocos mushrooms also works together with the Water plantain (Ze Xie) to improve the metabolism of Fluids and promote urination, thereby preventing a buildup of stagnant fluids.
Zhi Bo Di Huang Wan is used to treat Kidney and Liver Yin Deficiency
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 Zhi Bo Di Huang Wan is mostly used to treat the pattern "Kidney and Liver Yin Deficiency" which we describe below.
But before we delve into Kidney and Liver Yin Deficiency it is worth mentioning that it is often associated with the condition "vaginal itching". Again it wouldn't be correct to say "Zhi Bo Di Huang Wan treats vaginal itching". Rather, Zhi Bo Di Huang Wan is used to treat Kidney and Liver Yin Deficiency, which is sometimes the root cause behind vaginal itching.
Now let's look at Kidney and Liver Yin Deficiency, a pattern that TCM practitioners commonly treat with Zhi Bo Di Huang Wan.
