Hua Ban Tang is a 6-ingredient Chinese Medicine formula with Gypsum (Shi Gao) as a principal ingredient.
Invented in 1798 AD, it belongs to the category of formulas that clear Heat from Qi and Blood. Its main actions are: 1) clears Qi-level Heat and 2) cools the 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 Hua Ban Tang is used by TCM practitioners to fight patterns like Stomach Heat or Fire, Heat in the Blood or Stomach Fire or Stomach Heat. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as macular rash for instance.
On this page, after a detailed description of each of the six ingredients in Hua Ban Tang, we review the patterns and conditions that Hua Ban Tang helps treat.

Conditions and patterns for which Hua Ban 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 Hua Ban Tang is used by TCM practitioners to treat three different patterns which we describe below.
But before we delve into these patterns it is worth mentioning that they're often associated with the condition "macular rash". Again it wouldn't be correct to say "Hua Ban Tang treats macular rash". Rather, Hua Ban Tang is used to treat patterns that are sometimes the root cause behind macular rash.
Now let's look at the three patterns commonly treated with Hua Ban Tang.
