黄帝针经水胀篇云。肠覃何如。岐伯曰。寒气客于肠外。与卫相搏。卫气不得荣。因有所系。

The *Yellow Emperor's Classic of Acupuncture* (Huangdi Zhenjing), in the chapter "Water Swelling" (Shuizhang), states: "What is Changqin (intestinal polypoid mass)?" Qibo replied: "Cold pathogen invades outside the intestines, struggling with Wei Qi (defensive qi). Consequently, Wei Qi fails to circulate and nourish properly, becoming obstructed. Thus, a Jia mass (abdominal lump) forms and adheres internally, causing evil qi to arise, leading to the growth of flesh/polyps. Initially, it is as large as a chicken egg, gradually increasing in size until it resembles pregnancy when mature. If prolonged for over a year, it feels firm upon pressure but can be moved by pushing. Menstruation still occurs on time; this is its clinical presentation. 'Chang' refers to the Large Intestine; 'Qin' means extension or spreading. The Large Intestine is responsible for conducting waste and is the Fu organ of the Lung. The Lung governs Wei Qi. Wei Qi belongs to Qi; it dissipates when heated and coagulates when cooled. Now, cold pathogen resides in the Large Intestine, so Wei Qi cannot nourish properly, becomes obstructed, and forms a Jia mass adhering internally. This condition persists for a long time, hence named Changqin. When Qi scatters, it is clear; when Qi gathers, it is turbid. Condensing into a Jia mass causes evil qi to arise and flesh to grow. Gradually enlarging, the abdomen distends like pregnancy at maturity. This indicates pathology in Qi while Blood remains unaffected; thus, menstruation does not cease but occurs on time. This is originally not pregnancy, which can be distinguished by these signs."
