Sweet taste in the mouth 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 sweet taste in the mouth 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 sweet taste in the mouth is often associated with poor appetite, feeling of cold in the epigastrium and loose stools in the pattern “Cold-Damp invading the Spleen”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of sweet taste in the mouth we’ve identified that a herbal formula called Ping Wei San can help treat the patterns behind the symptom.
