Boils 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 boils 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 boils is often associated with carbuncles, sores and swellings in the pattern “Toxic Heat”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of boils we’ve identified that a herbal formula called Wu Wei Xiao Du Yin can help treat the patterns behind the symptom.
In Chinese Medicine boils is a symptom for the pattern "Toxic Heat". Below is a small explanation for it with links for more details.

Toxic Heat is often treated with Wu Wei Xiao Du Yin, a herbal formula made of 5 herbs (including Honeysuckle Flowers - Jin Yin Hua - as a key herb). Wu Wei Xiao Du Yin belongs to the category of "formulas that clear external abscesses and sores", which might be why it is often recommended for this pattern.
