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 watery milk, no feeling of distension of the breasts and fatigue in the pattern “Phlegm”. As you will see below, we have in record two 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 two herbal formulas that may help treat patterns behind the symptom.
We’ve also selected below the four medicinal herbs that we think are most likely to help treat bad breath.
The two "patterns of disharmony" that can cause bad breath
In Chinese Medicine bad breath is a symptom for 2 patterns that we have on record. Below is a small explanation for each of them with links for more details.
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 watery milk, no feeling of distension of the breasts and fatigue.
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".
The Large Intestine is a so-called "Fu" Organ. Learn more about the Large Intestine in Chinese Medicine
Dryness in Large Intestine
Pulse type(s): Fine (Xi)
Tongue color: Pale, Red
In addition to bad breath, other symptoms associated with Dryness in Large Intestine include constipation, dry stools and dry mouth.
Dryness in Large Intestine 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".
