鳖瘕者，谓腹中瘦结如鳖状是也。有食鳖触冷不消而生者，亦有食诸杂肉得冷变化而成者，
皆由脾胃气虚弱而遇冷，则不能克消所致。
瘕之为言假也，谓其有形，假而推移也。
昔曾有主共奴俱患鳖瘕，奴在前死，遂破其腹，得一白鳖仍故活。适有人乘白马来看白
鳖，白马遗尿落鳖上，即缩头。乃遂以马尿灌之，鳖化为水。其主曰∶吾将瘥矣。即服之，
果愈。（《巢氏病源》）
昔人患 症死，遗言令开腹取之，得病块坚硬如石，有文理。人谓异物，窃取，削成刀
柄。后因以刀割三棱，柄消成水，知此能疗 瘕。

鳖瘕，是指腹中结块形状像鳖一样的病证。有的是因为吃了鳖后受寒，导致食物无法消化而形成的；也有的是吃了各种杂肉后受寒，发生病变而成的。这些情况都是因为脾胃之气虚弱，遇到寒气时，不能运化消导所致。
“瘕”这个字的意思是“假”，是说它虽然摸得到有形之物，但位置不固定，可以推移移动。
过去曾经有一对主仆都患有鳖瘕，仆人先死了，于是剖开他的肚子，发现里面有一只白色的鳖，仍然活着。恰好有人骑着白马来看这只白鳖，马撒尿落在鳖身上，鳖就把头缩进去了。于是就用马尿灌喂它，鳖就化成水了。那个主人说：“我的病快要好了。”随即服下这种液体，果然痊愈了。（出自《巢氏病源》）
过去有个人患癥积而死，留下遗言让人剖开腹部取出病灶，取出的病块坚硬如石头，有纹理。人们认为是异物，偷偷拿走，把它削成了刀柄。后来因为用刀割三棱草，刀柄却化成了水，才知道这东西能治疗癥瘕。
显庆寺的一位僧人患病沉积数年，虽然不需要卧床枕着休息，但每天凌晨四更天后感到心口闷硬，无法安睡，必须起身走动。寺里的人习以为常，没人知道这是什么病。他向戴人（张从正）求药。戴人让他用涌吐法，吐出胶状涎液一二升，颜色像黑矾水，接着又吐出黄绿色的水，随后又泻下脓血几升。从此以后，他觉得胸中好像失去了巨大的山峦，饮食无数。
果菌村的刘子平的妻子腹中有个肿块像瓢一样大，已经十八年了。月经断绝，各种方法都治不好。戴人让她在一个月内涌吐四次，泻下六次。排出的痰液大约有一两桶，其中有不消化的东西，形状像煮烂的葵菜和鱼肠，感觉病积像被割除一样，渐渐平复。等到积聚完全清除，原来的肿块痕迹像杵臼一样，身体几乎没有受损，到了这时面色恢复了年轻的光彩，月经也重新来潮。
阳夏县的主簿之妻患有肥气病，起初像酒杯那么大，每次发作时发冷发热。十五六年后，因为心情悲伤感慨，病情更加严重，只有心下约三指宽的地方没有病，整个腹部像石板一样硬，不能坐卧，针灸服药都没有效果。恭敬地邀请戴人前来，到达后诊断说：“这是肥气病，得于夏季末，位于左胁下像倒扣的杯子，久治不愈，会让人发疟疾样的寒热。”用瓜蒂散催吐，吐出鱼胶状的黄涎液一二升，到了晚上接着服用舟车丸、通经散。五更天时，黄涎和脓血各半，腹泻五六次，凡是积聚的地方都感到疼痛。后来用白术散、当归散配合调和气血经络的药物，经过这样的涌吐和泻下三四次后才痊愈。这大概是积聚时间很长的病例。
Bi Jia (Turtle-shaped Mass) refers to a condition where a mass in the abdomen is shaped like a turtle. Some cases arise from consuming turtle meat followed by exposure to cold, leading to indigestion; others result from eating various meats and then encountering cold, causing pathological changes. All these are caused by deficiency of Spleen and Stomach Qi, which fails to transform and transport when confronted with cold pathogens.
The term "Jia" (Mass) implies "false," indicating that although a tangible mass exists, it is movable and can be shifted in position.
In the past, a master and his servant both suffered from Bi Jia. The servant died first, and upon opening his abdomen, a white turtle was found still alive. Coincidentally, someone riding a white horse came to see the turtle; the horse urinated on the turtle, causing it to retract its head. Consequently, horse urine was forced into the turtle, which dissolved into water. The master said, "My illness will soon be cured." He drank the liquid and indeed recovered. (From *Chao Shi Bing Yuan*)
In another instance, a person died suffering from Zheng Accumulation (hard, fixed masses). His dying wish was for his abdomen to be opened to remove the lesion. The extracted mass was hard as stone with visible grain patterns. People considered it a foreign object, stole it, and carved it into a knife handle. Later, when using this knife to cut *Sambucus chinensis* (Lian Qiao/San Leng context implies cutting herbs), the handle dissolved into water, revealing its efficacy in treating Zheng Jia.
A monk at Xianqing Temple had been ill for several years. Although he did not need to lie in bed, after the fourth watch (around 1-3 AM), he felt stifling hardness in his heart region and could not sleep peacefully, requiring him to get up and walk. The temple residents became accustomed to this, unaware of the disease. He sought treatment from Dai Ren (Zhang Congzheng). Dai Ren induced emesis, expelling one or two sheng of gelatinous phlegm resembling black alum water, followed by yellow-green fluid, and subsequently purged several sheng of pus and blood. Thereafter, he felt as if a huge mountain had been removed from his chest, and his appetite returned significantly.
The wife of Liu Ziping from Guojun Village had an abdominal mass the size of a ladle for eighteen years. Her menstruation had ceased, and all other treatments failed. Dai Ren instructed her to undergo emesis four times and purgation six times within one month. Approximately one or two buckets of phlegm were expelled, containing undigested matter resembling boiled okra and fish intestines. She felt the accumulation being excised, gradually subsiding. Once the accumulation was completely cleared, the scar of the mass resembled a mortar, with no significant damage to her body. At this point, her face regained a youthful complexion, and her menstruation resumed.
The wife of the Magistrate of Yangxia suffered from Fei Qi (Liver Enlargement/Mass). Initially, it was the size of a wine cup, accompanied by alternating chills and fever upon each flare-up. After fifteen or sixteen years, exacerbated by grief and sorrow, the condition worsened severely. Only an area about three fingers wide below the heart remained unaffected; the rest of the abdomen was hard as a stone slab, preventing sitting or lying down. Acupuncture and herbal medicine proved ineffective. Respectfully inviting Dai Ren, upon diagnosis, he stated: "This is Fei Qi, contracted in late summer, located under the left hypochondrium like an inverted cup. If untreated for long, it causes malaria-like chills and fevers." He administered Gua Di San (Melon Pedicle Powder) to induce vomiting, expelling one or two sheng of yellow, fish-glue-like phlegm. That night, he continued treatment with Zhou Che Wan (Boat and Cart Pill) and Tong Jing San (Unblocking Meridian Powder). At the fifth watch (around 3-5 AM), she passed five or six stools consisting of half yellow phlegm and half pus/blood, experiencing pain in all areas of accumulation. Subsequently, Bai Zhu San (Atractylodes Macrocephala Powder) and Dang Gui San (Angelica Sinensis Powder) were used combined with herbs to harmonize blood flow and meridians. After three or four cycles of emesis and purgation, the disease finally resolved. This case illustrates a long-standing accumulation.
