Gui Ling Gan Lu Yin is a 9-ingredient Chinese Medicine formula with Talc (Hua Shi) as a principal ingredient.

Invented in 1172 AD, it belongs to the category of formulas that dispel Summer-Heat and facilitate resolution of Dampness. Its main actions are: 1) expels Summerheat and 2) clears 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 Gui Ling Gan Lu Yin is used by TCM practitioners to fight patterns like Summer Heat with Dampness. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as acute gastroenteritis, cholera or heat stroke for instance.

On this page, after a detailed description of each of the nine ingredients in Gui Ling Gan Lu Yin, we review the patterns and conditions that Gui Ling Gan Lu Yin helps treat.
