This paper introduces Prof. WANG Qingqi’s experience in treating colorectal polyps from "abdominal mass". The first principle is to relieve intestines and stomach. According to the "seed-soil theory"of cancer

if the regional micro ecological environment of the gastrointestinal tract is improved

it is difficult for cell mutation and tumor to grow. Gastrointestinal function is regulated taking Qi-blood

cold-heat and deficiency-excess as key links to treat the root cause. The second principle is to remove pathogenic abdominal mass. Intestinal tract is the "official of transportation". Hard masses should be disintegrated. Colorectal polyps are mostly due to longtime accumulation of phlegm

blood stasis

dampness and toxin

and finally forming into abdominal mass. The treating methods include:resolving dampness

activating blood stasis

catharsis and removing abdominal mass toxicity.
