巢元方曰∶八瘕者，皆胞胎生产，月水往来，血脉精气不调所生也。肾为阴，主开闭，左为胞门，右为子
户，主月水、生子之道。胞门子户，主精血神气出入，合于中黄玉门四边，主持关元，禁闭子精。脐下三寸，
名曰关元，主藏魂魄。妇人之胞，三焦之府，常所从止。若妇人经脉俞络合调，月水以时来至，能生子而无病。
如经络荣卫继绝不通，邪气便得往来，入合于脏。若生血未尽而合阴阳，即令血脉挛急，小腹重急，支满胸胁，
四肢酸痛，饮食不调，结牢恶血不除，月水不时，因生积聚，如怀胎状，阴中肿，内生风，小便不利，若痛如
淋状，久不复生子。
慎斋按∶《巢氏病源》论妇人八瘕，不外新产、月水之后，感寒湿风冷，凝泣血脉，留滞经络，闭塞隧道
而成也。乃强分黄瘕、青瘕、燥瘕、血瘕、脂瘕、狐瘕、蛇瘕、鳖瘕之名，以惑世诬名，宜其为张戴人所斥也。
夫瘕者假也，不过假人身之气血，加以食积痰饮，胶结成形。《内经》止有石瘕，生于胞中一证，何尝有为黄
为青之名色耶？既有八瘕之证，医者亦难辨其是狐是蛇是鳖也，因删之。《妇人良方》中，但存八瘕之名，而
不载条目，最有见。
《妇人良方》曰∶妇人脏腑调和，经脉循环，月水以时，故能生子无病。若乘外邪而合阴阳，则小腹胸胁
腰背，相引而痛，月事不调，阴中肿胀，小便淋沥而色黄黑，则瘕生矣。八瘕者，黄、青、燥、血、脂、狐、
蛇、鳖是也，《千金》、《外台》，言之详矣。
薛立斋按∶经云气主煦之，血主濡之。若血不流，则凝而为瘕。瘕者，中虽硬而忽聚忽散。多因六淫七情，
饮食起居，动伤脏腑而成，当与 癖诸证治同，慎不可复伤元气。
Chao Yuanfang stated: The "Eight Leiomas" (masses in the lower abdomen of women) are all caused by the imbalance of blood vessels and essence-qi during conception, childbirth, and menstruation. The Kidney is Yin and governs opening and closing; the left side is called the "Gate of the Womb" (Baomen), and the right side is called the "House of the Child" (Zihu), which govern the pathways for menstruation and reproduction. Baomen and Zihu govern the entry and exit of essence, blood, and divine qi, connecting with the four sides of the central yellow jade gate, overseeing the Guanyuan point, and sealing off sperm. Three cun below the umbilicus is named Guanyuan, which governs the storage of Hun and Po souls. The woman's uterus is the mansion of the Sanjiao (Triple Burner) and is where Qi and Blood commonly stop and flow. If a woman's meridians and Shu points are harmonious, and menstruation arrives on time, she can bear children without illness. However, if the Ying (Nutrient) and Wei (Defensive) Qi in the meridians become severed and blocked, pathogenic factors can invade and combine with the Zang organs. If intercourse occurs while blood generation is incomplete, it causes blood vessels to spasm and tighten, resulting in heaviness and urgency in the lower abdomen, distension and fullness in the chest and hypochondrium, soreness and pain in the four limbs, irregular diet, accumulation of stubborn bad blood that is not eliminated, irregular menstruation, leading to the formation of accumulations that resemble pregnancy, swelling of the vagina, internal wind generation, difficult urination, and pain resembling strangury (Lin syndrome). Over time, this prevents further reproduction.
Shen Zhai commented: The *Chao Shi Bing Yuan* discusses the Eight Leiomas in women, attributing them primarily to contracting cold-dampness or wind-cold after childbirth or menstruation, causing blood vessels to coagulate and stagnate, remaining in the meridians and blocking the tunnels. This arbitrary distinction into names such as Yellow Leioma, Green Leioma, Dry Leioma, Blood Leioma, Fat Leioma, Fox Leioma, Snake Leioma, and Turtle Leioma serves only to confuse the world and distort facts, which explains why Zhang Dairen criticized it. The term "Leioma" implies something false or illusory; it is merely formed by the adhesion of food retention and phlegm-fluids to the body's Qi and Blood. The *Neijing* mentions only one case of Stone Leioma arising in the Baozhong (uterus); where did the names for yellow and green come from? Since there are these eight types of Leiomas, physicians would find it difficult to distinguish whether they are fox, snake, or turtle, so I have deleted them. The *Furen Liangfang* retains only the names of the Eight Leiomas without listing specific entries, which shows great insight.
The *Furen Liangfang* states: When a woman's Zang-Fu organs are harmonious and her meridians circulate smoothly, allowing menstruation to arrive on time, she can bear children without illness. If she engages in intercourse while vulnerable to external pathogens, it leads to pulling pain in the lower abdomen, chest, hypochondrium, waist, and back, irregular menstruation, swelling of the vagina, and dribbling urine that is yellow-black in color; thus, Leiomas arise. The Eight Leiomas refer to Yellow, Green, Dry, Blood, Fat, Fox, Snake, and Turtle, which are discussed in detail in the *Qianjin Fang* and *Waitai Miyao*.
Xue Lizhai commented: The classics state that Qi provides warmth, and Blood provides nourishment. If Blood does not flow, it coagulates to form Leiomas. A Leioma is characterized by hardness in the center but with a tendency to gather and disperse intermittently. It is mostly caused by the Six Evils (Wind, Cold, Summerheat, Dampness, Dryness, Fire) and Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright), as well as improper diet and daily habits, which injure the Zang-Fu organs. Its treatment should be similar to that of Pi Ji (accumulations and masses), and one must strictly avoid damaging the Original Qi (Yuan Qi).
