Lusterless and yellow complexion 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 lusterless and yellow complexion 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 lusterless and yellow complexion is often associated with heat and pain in the joints, reduced mobility and fever in the pattern “Painful Obstruction due to Damp Heat in Channels”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of lusterless and yellow complexion we’ve identified that a herbal formula called Xuan Bi Tang can help treat the patterns behind the symptom.
