Itchy ears 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 itchy ears 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 itchy ears is often associated with chest pain, constipation and anger in the pattern “Wind-Phlegm”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of itchy ears we’ve identified that a herbal formula called Ban Xia Bai Zhu Tian Ma Tang can help treat the patterns behind the symptom.
