Wei Jing Tang is a 4-ingredient Chinese Medicine formula with Common Reed Rhizomes (Lu Gen) as a principal ingredient.
Invented in 627 AD, it belongs to the category of formulas that clear internal abscesses and sores. Its main actions are: 1) clears heat from the Lungs and 2) transforms Phlegm.
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 Wei Jing Tang is used by TCM practitioners to fight patterns like /tcm-education-center/patterns/qi-and-blood-stagnation or /tcm-education-center/patterns/wind-heat_entering_the_lungs. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as absence of menstruation, bronchitis or bronchiectasis for instance.
On this page, after a detailed description of each of the four ingredients in Wei Jing Tang, we review the patterns and conditions that Wei Jing Tang helps treat.
Lu Gen is a king ingredient in Wei Jing Tang. Like the name indicates, it means it has more power than other ingredients in the formula.
Part used: Fresh or dried rhizome
Lu Gen clears Heat from the Lungs. In Encountering the Sources of the Classic of Materia Medica, the 17th-century physician Zhang Lu wrote that it "specializes in facilitating passage through the orifices and thus is good at treating Lung abscess."
Yi Yi Ren is a deputy ingredient in Wei Jing Tang. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
Part used: Dried ripe kernel
Category: Herbs that drain Dampness
Yi Yi Ren clears Heat from the Lungs and disperses pus from the upper parts of the body. It also leaches out Dampness and helps restore proper function to the Intestines, thereby providing an outlet for Dampness and Heat through the urine.
Dong Gua Zi is a deputy ingredient in Wei Jing Tang. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
Part used: The seeds, dried
Category: Herbs that drain Dampness
In general Dong Gua Zi's main actions are as follows: "Clears Heat, expels Phlegm, expels pus and moistens the Lungs. Clears Heat and drains Dampness."
Tao Ren is an assistant ingredient in Wei Jing Tang. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
Part used: Dried ripe seed
Category: Herbs that invigorate the Blood
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 Wei Jing Tang is used by TCM practitioners to treat two 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:
Again it wouldn't be correct to say "Wei Jing Tang treats absence of menstruation" for instance. Rather, Wei Jing Tang is used to treat patterns that are sometimes the root cause behind absence of menstruation.
Now let's look at the two patterns commonly treated with Wei Jing Tang.
