Gan Cao Gan Jiang Tang is a 2-ingredient Chinese Medicine formula with Dried Ginger (Gan Jiang) as a principal ingredient.
Invented in 220 AD, it belongs to the category of formulas that warm Interior Cold. Its main actions are: 1) warms the Lungs and 2) strengthens the Stomach.
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 Gan Cao Gan Jiang Tang is used by TCM practitioners to fight patterns like Lung Yang Deficiency. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as enuresis, excessive drooling or allergic rhinitis for instance.
On this page, after a detailed description of each of the two ingredients in Gan Cao Gan Jiang Tang, we review the patterns and conditions that Gan Cao Gan Jiang Tang helps treat.
Gan Jiang is a king ingredient in Gan Cao Gan Jiang Tang. Like the name indicates, it means it has more power than other ingredients in the formula.
Part used: Dried rhizome
Gan Jiang warms the Lungs and disperses Cold. Its primary function is to restore the Yang in chest. However, its acrid and hot nature can hurt the Lungs by depleting the source Qi. To overcome this problem, blast fried Ginger is recommended as its acrid and dispersing effect is reduced.
Gan Cao is a deputy ingredient in Gan Cao Gan Jiang Tang. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
Part used: Dried root and rhizome
Category: Tonic herbs for Qi Deficiency
Gan Cao tonifies the Qi. Together with Dried ginger, they warm and strengthen the Stomach, which in turn assist in resolving the Lungs disharmony. According to the the five phases theory, nurturing the earth (Stomach) can generate the metal (Lungs). The combination of sweet and acrid herbs warms the Yang and augments the Qi in a balanced manner.
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 Gan Cao Gan Jiang Tang is mostly used to treat the pattern "Lung Yang Deficiency" which we describe below.
But before we delve into Lung Yang Deficiency here is an overview of the Western conditions it is commonly associated with:
Again it wouldn't be correct to say "Gan Cao Gan Jiang Tang treats enuresis" for instance. Rather, Gan Cao Gan Jiang Tang is used to treat Lung Yang Deficiency, which is sometimes the root cause behind enuresis.
