Loss of taste 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 loss of taste 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 loss of taste is often associated with poor appetite, loose stools and fatigue in the pattern “Stomach Qi Deficiency”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of loss of taste we’ve identified that a herbal formula called Si Jun Zi Tang can help treat the patterns behind the symptom.
In Chinese Medicine loss of taste is a symptom for the pattern "Stomach Qi Deficiency". Below is a small explanation for it with links for more details.
