Anus swelling 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 anus swelling 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 anus swelling is often associated with constipation, burning sensation in the mouth and burning sensation in the anus in the pattern “Heat in the Large Intestine”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of anus swelling we’ve identified that a herbal formula called Ma Zi Ren Wan can help treat the patterns behind the symptom.
In Chinese Medicine anus swelling is a symptom for the pattern "Heat in the Large Intestine". Below is a small explanation for it with links for more details.

Heat in the Large Intestine is often treated with Ma Zi Ren Wan, a herbal formula made of 7 herbs (including Hemp Seeds - Huo Ma Ren - as a key herb).
