Qing Wei San is a 5-ingredient Chinese Medicine formula with Goldthread Rhizomes (Huang Lian) as a principal ingredient.
Invented in 1336 AD, it belongs to the category of formulas that clear Heat from the Organs. Its main actions are: 1) drains Stomach Fire 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 Qing Wei San is used by TCM practitioners to fight patterns like Stomach Fire or Stomach Heat. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as stomatitis, periodontitis or glossitis for instance.
On this page, after a detailed description of each of the five ingredients in Qing Wei San, we review the patterns and conditions that Qing Wei San helps treat.
The five ingredients in Qing Wei San
Huang Lian is a king ingredient in Qing Wei San. Like the name indicates, it means it has more power than other ingredients in the formula.
1. Goldthread Rhizomes (Huang Lian)
Part used: Dried rhizome
Nature: Cold
Taste(s): Bitter
Meridian affinity: GallbladderSpleenStomachHeartLarge intestineLiver
Category: Herbs that clear Heat and dry Dampness
In general Huang Lian's main actions are as follows: "Expels Damp-Heat especially in the Lower Burner. Eliminates Fire toxicity especially when there is associated Dampness. Acts as a sedative by eliminating Heart Fire. Eliminates Stomach Fire. Expel parasites"
In the context of Qing Wei San, it is used because it attacks the Stomach Fire and drains the accumulation of Heat.
Sheng Ma is a deputy ingredient in Qing Wei San. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
2. Bugbane Rhizomes (Sheng Ma)
Sheng Ma raises and disperses the Heat and resolves toxicity. Discussion of Medicinal Properties, a Chinese medicine classic, lists it as a specific herb for toothache, ulcers, and festering sores in the mouth. Its synergy with Goldthread rhizome (Huang Lian) , the key herb in this formula, ensures that draining of Fire does not harm the Qi dynamic, and that the ascent of Yang does not further fan the rising Fire.
Mu Dan Pi is an assistant ingredient in Qing Wei San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
3. Mudan Peony Bark (Mu Dan Pi)
Part used: Root barks
Nature: Cool
Meridian affinity: HeartKidneyLiver
Category: Herbs that cool the Blood
Mu Dan Pi works together with Unprepared Rehmannia (Sheng Di Huang), another assistant herb here, to cool the Blood and nourish the Yin.
Dang Gui is an assistant ingredient in Qing Wei San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
4. Dong Quai (Dang Gui)

Category: Tonic herbs for Blood Deficiency
In general Dang Gui's main actions are as follows: "Tonifies the Blood. Lubricates the Intestines. Relieve constipation. Promotes circulation and dispels Bi Pain. Reduce Dysmenorrhea and help with irregular menstruation."
In the context of Qing Wei San, it is used because it reduces swelling and alleviates pain by harmonizing the Blood.
5. Unprepared Rehmannia (Di Huang)
Part used: Prepared dried root tuber
Nature: Cold
Taste(s): Sweet
Meridian affinity: HeartKidneyLiver

Qing Wei San is used to treat Stomach Fire or Stomach Heat
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 Qing Wei San is mostly used to treat the pattern "Stomach Fire or Stomach Heat" which we describe below.
But before we delve into Stomach Fire or Stomach Heat here is an overview of the Western conditions it is commonly associated with:
Stomatitis Periodontitis Glossitis Trigeminal neuralgia
Again it wouldn't be correct to say "Qing Wei San treats stomatitis" for instance. Rather, Qing Wei San is used to treat Stomach Fire or Stomach Heat, which is sometimes the root cause behind stomatitis.
Now let's look at Stomach Fire or Stomach Heat, a pattern that TCM practitioners commonly treat with Qing Wei San.
The Stomach is a so-called "Fu" Organ. Learn more about the Stomach in Chinese Medicine

Patients with Stomach Fire or Stomach Heat typically exhibit slippery (Hua) or floating (Fu) pulses as well as a red tongue with yellow coating.
