Foul 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 foul 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 foul breath is often associated with nausea, sour regurgitation and belching in the pattern “Food Stagnation in the Stomach”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of foul breath we’ve identified two 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 foul breath.
