Li stated: Changqin (intestinal polypoid mass) is caused by cold pathogenic qi invading the Large Intestine and struggling with Stomach qi. The Large Intestine serves as the transmitting organ for the Lung, and the Lung governs Qi movement. Qi flows freely when heated but coagulates when exposed to cold. Upon coagulation, clear Yang qi scatters, while turbid Yin qi knots to form a Jia mass (a movable abdominal mass). If this condition persists for a long time, polyps will grow. Initially, it is the size of a chicken egg; later, it becomes as large as a pregnancy abdomen. It feels firm upon palpation and can be moved upon pushing. Menstruation occurs on schedule, though the volume may vary. This indicates a disorder of Qi without yet affecting Blood. It is appropriate to use Erchen Tang (Two-Aged Decoction) added with Xiangfu (Cyperus Rhizome) to open and regulate Qi, or alternatively, Xiangfen Wan (Xiangfen Pill).

Zhunsheng states: Ancient formulas mention the names of Wuji (Five Accumulations), Liuju (Six Gatherings), Qixia (Seven Hysteromas), and Baxia (Eight Hysteromas). The accumulation of Qi in the Five Zang organs is called "Ji" (Accumulation), hence there are five types of Ji; the gathering of Qi in the Six Fu organs is called "Ju" (Gathering), hence there are six types of Ju. These are discussed in detail in the miscellaneous diseases section of *Zhunsheng* (The Standard of Medicine). (Hysteroma [Jia], Accumulation [Ji], and Gathering [Ju] all originate from Qi dysfunction, hence the terms Qi-Ji and Qi-Ju exist. However, regarding the view that Hysteroma belongs to Blood disorders, it is because Qi gathering leads subsequently to Blood coagulation. Cases involving夹杂 food stagnation or Phlegm vary according to the accumulated substance. Phlegm, Blood, and Food all rely on Qi for their transformation and movement; thus, when Qi moves, substances generate; when Qi is diseased, substances become diseased. This is why all diseases arise from Qi, and why agents for invigorating Blood, resolving Phlegm, and digesting Food must necessarily include Qi-regulating herbs.) As for Qixia and Baxia, they occur mostly in women. "Seven" is the number of Fire, associated with the Heart, since Blood is generated by the Heart; "Eight" is the number of Wood, associated with the Liver, since Blood returns to the Liver. Although these distinctions are somewhat forced, the principles seem distinct. "Qian" (referring to hard masses like Shi-Qian) means firm/hard, which is difficult to break; "Jia" means false/provisional, taking shape by borrowing external matter. Ancients regarded women's diseases as stubborn conditions, attributing the formation of Hysteroma to creatures like dragons and jiao. However, one need not adhere rigidly to such views. Women's Qian and Jia both belong to Blood disorders. Matters such as Longxia (Dragon Hysteroma), Shexia (Snake Hysteroma), Yuxia (Fish Hysteroma), Biexia (Turtle Hysteroma), Roufa (Flesh Emission), and Shixia (Lice Hysteroma) are accidental occurrences. They result from mistakenly ingesting certain items during diet, which remain in the abdominal viscera and take form by borrowing Blood, possessing their own vitality. This is similar to a monk in the Yonghui era who suffered from dysphagia; he had an object in his abdomen shaped like a fish, which constituted a living Hysteroma. Although the internal pathogens differ from those causing stagnant Blood to condense into痞块 (stubborn masses), the treatment methods should follow similar categories. As the saying goes, "The physician relies on intuitive understanding." For example, using worn-out combs to treat Shixia (using worn-out combs and hairpins together, likely based on symbolic resonance, though perhaps not entirely optimal); using copper filings to treat Longxia; using Qu Bai (fermented wheat and cypress leaves) to treat Mixia; using Duanshi (calcined iron oxide) to treat Jiu Xia (Alcohol Hysteroma). Scholars can understand such methods through analogy.
