During a colonoscopy, we can see that the mucosa of the rectum is swollen and eroded, and there is also mucus attached to the intestines. The reason for the mucus production is due to exudation caused by inflammation.

In terms of Western medical treatment, the main approach is to regulate the intestinal flora using probiotics. However, the treatment outcomes are not particularly ideal, and there are no specific effective drugs in Western medicine. In contrast, Chinese medicine has its strengths in treating this disease. It diagnoses and treats patients based on their constitution, achieving relatively good results. Additionally, Chinese medicine includes external treatments such as enemas and herbal hydrotherapy, which can apply medicinal effects directly to the surface of the intestinal mucosa. These methods are very effective in treating proctitis.
