Bad breath can be the consequence of several so-called “patterns of disharmony” in Chinese Medicine.
Chinese Medicine sees the body as a system, not a sum of isolated parts. A "pattern" is when the system's harmony is disrupted, leading to symptoms or signs that something is wrong (like bad breath here). It is similar to the concept of disease in Western Medicine but not quite: a Western disease can often be explained by several Chinese patterns and vice-versa.
A pattern often manifests itself in a combination of symptoms that, at first glance, do not seem necessarily related to each others. For instance here bad breath is often associated with dry stools, dry mouth and dry throat in the pattern “Large Intestine Dryness”. As you will see below, we have in record three patterns that can cause bad breath.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of bad breath we’ve identified four herbal formulas that may help treat patterns behind the symptom.
We’ve also selected below the five medicinal herbs that we think are most likely to help treat bad breath.
The three "patterns of disharmony" that can cause bad breath
In Chinese Medicine bad breath is a symptom for 3 patterns that we have on record. Below is a small explanation for each of them with links for more details.
The Large Intestine is a so-called "Fu" Organ. Learn more about the Large Intestine in Chinese Medicine
Large Intestine Dryness
Pulse type(s): Fine (Xi)
In addition to bad breath, other symptoms associated with Large Intestine Dryness include dry stools, dry mouth and dry throat.
Large Intestine Dryness is often treated with Zeng Ye Tang, a herbal formula made of 3 herbs (including Ningpo Figwort Roots - Xuan Shen - as a key herb). Zeng Ye Tang belongs to the category of "formulas that enrich yin and moisten dryness", which might be why it is often recommended for this pattern. Its main action as a formula is: "Nourishes Yin and Essence".
The Stomach is a so-called "Fu" Organ. Learn more about the Stomach in Chinese Medicine
Stomach Heat or Fire
Pulse type(s): Rapid (Shu), Slippery (Hua), Full (Shi)
Tongue coating: Yellow coating
Tongue color: Red centre
Stomach Fire indicates a true Excess of Heat in the Stomach, creating symptoms such as mouth ulcers, bad breath, intense thirst and gum bleeding. Stomach Fire can be the result of excessive intake of hot, spicy, greasy and deep fried foods or other factors such as alcohol, tobacco and sugar.
In addition to bad breath, other symptoms associated with Stomach Heat or Fire include dry stools, dry mouth and irritability.
Stomach Heat or Fire is often treated with Tiao Wei Cheng Qi Tang, a herbal formula made of 3 herbs (including Rhubarb - Da Huang - as a key herb). Tiao Wei Cheng Qi Tang belongs to the category of "formulas that purge heat accumulation", which might be why it is often recommended for this pattern.

Crow-Dipper Rhizomes (Ban Xia) is the king ingredient for Er Chen Tang, a formula used for Phlegm
Phlegm
Pulse type(s): Slippery (Hua), Wiry (Xian)
Tongue coating: Sticky coating, Thick coating
Tongue shape: Swollen
The concept of Phlegm is much wider and important in Chinese Medicine than in the West. Broadly speaking, Phlegm is a substance produced when the body fails to handle Body Fluids properly.
In addition to bad breath, other symptoms associated with Phlegm include dizziness, watery milk and no feeling of distension of the breasts.
From a Western Medicine standpoint Phlegm is associated with health issues such as Low Breast Milk Supply, Late Menstruation or Scanty Menstruation.
Phlegm is often treated with Er Chen Tang, a herbal formula made of 5 herbs (including Crow-Dipper Rhizomes - Ban Xia - as a key herb). Er Chen Tang belongs to the category of "formulas that dry dampness and transform phlegm", which might be why it is often recommended for this pattern. Its main action as a formula is: "Dries Damp and dispels Phlegm".
