Itchy skin 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 skin 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 skin is often associated with poor appetite, feeling of heaviness and thirst without a desire to drink in the pattern “Damp-Heat invading the Spleen”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of itchy skin we’ve identified that a herbal formula called Lian Po Yin can help treat the patterns behind the symptom.
