Cold in the lower abdomen 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 cold in the lower abdomen 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 cold in the lower abdomen is often associated with painful period, infertility and late period in the pattern “Full Cold in the Directing and Penetraing Vessels”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of cold in the lower abdomen we’ve identified that a herbal formula called Wen Jing Tang can help treat the patterns behind the symptom.
