Spitting up bitter or sour fluids 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 spitting up bitter or sour fluids 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 spitting up bitter or sour fluids is often associated with mild chills alternating with pronounced fever, bitter taste in the mouth and stifling sensation in the chest in the pattern “Heat in Gall Bladder”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of spitting up bitter or sour fluids we’ve identified that a herbal formula called Hao Qin Qing Dan Tang can help treat the patterns behind the symptom.
