或脏腑虚弱，或食甘肥则虫动，动则腹中痛，发作肿聚，往来上下，痛不休止，上攻心痛，口喜吐涎
及清水，贯伤心者死。其脉凡腹痛法当沉弱而弦。今反洪大则是虫也。仲景用乌梅丸治之。诸杀虫药皆可
疗，使君子尤良。蛔虫束行，吴茱萸根尤胜。
一人年十八，自小面带微黄，五月间腹大痛。医以小建中加丁香两帖，不效，加呕吐清汁；又与十八
味丁香透膈汤两帖，食全不进，痛无休止，如此者五、
六日；又与阿魏丸百余粒，至夜发热不睡，口却不渴，脉左二部沉弦而数实，痛处不可按；遂与大柴胡汤
四帖加甘草下之，痛呕虽减，食犹未进；遂与小柴胡汤去黄芩、人参，加芍药、陈皮、黄连、生甘草，二十
帖而愈。
一人年十七，家贫多劳，十一月病恶寒而吐血两三日，六脉紧涩，一月后食减中痞。医投温胆汤、枳
壳汤，三日后发热，口干不渴，口中有痰。予曰∶此感寒也。询之，八日前曾于霜中渡水三、四次，心下
有悲泣事，腹亦饥。遂以小建中汤去芍药，加桔梗、陈皮、半夏，四帖而愈。
即《内经》丹 ，由其丹之流走，故名丹瘤。古方所谓赤游肿，因肌肉虚，为风毒热气所乘，搏于气
血，则肌肤赤而肿起，其风随气行不定，故名。赤游肿俗谓之瘤，由风热发丹，流走经络，散发肌表，如
丹之赤，如火之烧也。若遍身发赤，曰天火丹之类三十余条。治法随其所在而镰之，泄去毒瓦斯；不尔，则
丹毒入腹近心则死。但初发心痛者，不可镰尔！用药
内饮、外敷各有方，大抵散风热、和气、活血、凉肌而已。《原病式》亦曰∶赤溜热胜气也，火之色，
相火主之。游肿一 一赤溜一也。
如果脏腑虚弱，或者食用了甘甜肥腻的食物，就会导致蛔虫躁动。蛔虫一旦躁动，腹部就会疼痛，出现时聚时散的肿块，疼痛上下游走，持续不止。若蛔虫上攻至心部引起心痛，且口中喜欢吐出涎液及清水，若蛔虫贯穿心脏则会导致死亡。凡是腹痛，脉象通常应当表现为沉、弱而弦。现在反而出现洪大的脉象，这说明是蛔虫病。张仲景使用乌梅丸来治疗此病。各种杀虫药物都可以治疗，其中使君子效果尤为良好。对于蛔虫聚集成团的情况，吴茱萸根的效果尤其显著。
有一个十八岁的年轻人，从小面色微黄，五月间腹部剧烈疼痛。医生先用小建中汤加入丁香，服用两帖后无效，反而出现了呕吐清汁的症状；接着又给予十八味丁香透膈汤，服用两帖后，完全无法进食，疼痛没有停止，像这样持续了五六天；随后又给予阿魏丸一百多粒，到了夜晚发热无法入睡，但口并不渴，脉象左侧两部呈现沉、弦、数且实的特点，疼痛部位不可按压；于是给予大柴胡汤四帖并加入甘草以泻下，虽然疼痛和呕吐有所减轻，但饮食仍未恢复；接着给予小柴胡汤，去掉黄芩、人参，加入芍药、陈皮、黄连、生甘草，服用二十帖后痊愈。
有一个十七岁的年轻人，家境贫寒且劳作过度，十一月时患病，表现为怕冷并吐血两三天，六脉紧涩，一个月后食欲减退且胸脘痞闷。医生投用温胆汤、枳壳汤，三日后出现发热，口干但不想喝水，口中有痰。我说：这是感受寒邪所致。询问得知，八日前曾在霜雪中渡水三四次，心中又有悲伤哭泣之事，且腹部处于饥饿状态。于是用小建中汤去掉芍药，加入桔梗、陈皮、半夏，服用四帖后痊愈。
这就是《内经》中提到的丹瘤，因为这种病症像丹砂一样流动游走，所以命名为丹瘤。古方中所说的赤游肿，是因为肌肉虚弱，被风毒热气所侵袭，搏结于气血之中，导致肌肤发红且肿胀隆起，风气随着气机运行而不定，所以得名。赤游肿在民间被称为瘤，是由风热引发丹毒，流走于经络，散发于肌表，颜色如丹砂之红，感觉如火烧一般。如果全身都发出红斑，属于天火丹之类，共有三十多条记载。治疗方法根据病灶所在之处进行砭镰（刺破放血），泄去毒气；如果不这样做，丹毒进入腹内，靠近心脏就会导致死亡。但是，如果初发时伴有心痛症状的，不可以进行砭镰！用药方面，内服和外敷各有方剂，大体上是疏散风热、调和气机、活血凉肌而已。《原病式》中也说：赤溜是热胜气的表现，红色属火，由相火主导。游肿就是赤溜，是一回事。
If the Zang-Fu organs are weak, or if one consumes sweet and fatty foods, it will cause roundworms to move. Once the roundworms move, abdominal pain occurs, with masses that gather and disperse intermittently, moving up and down, with unceasing pain. If the worms attack upward to the heart causing heart pain, and the mouth frequently spits saliva and clear fluid, death ensues if the worms penetrate the heart. In cases of abdominal pain, the pulse should typically be deep, weak, and wiry. Now, if it is instead surging and large, this indicates roundworm disease. Zhang Zhongjing used Wumei Wan (Mume Pill) to treat it. Various anti-worm medications can be used for treatment, with Shijunzi (Quisqualis Fructus) being particularly effective. For roundworms clustering together, Wu Zhu Yu Gen (Evodiae Radix) is especially superior.
An eighteen-year-old person, who had a slightly yellow complexion since childhood, suffered from severe abdominal pain in May. The physician first prescribed Xiao Jianzhong Tang (Minor Construct the Middle Decoction) with added Dingxiang (Caryophylli Flos), taken for two doses, but without effect; vomiting of clear juice ensued. Then, Shiba Wei Dingxiang Touge Tang (Eighteen-Ingredient Clove Penetrating Diaphragm Decoction) was given for two doses; food intake ceased completely, and the pain did not cease, lasting thus for five or six days. Subsequently, Awei Wan (Ferula Pill) was administered, over a hundred pills; at night, fever developed and sleep was impossible, yet there was no thirst. The pulse on the left side, both positions, was deep, wiry, rapid, and excess, and the painful area could not be pressed. Therefore, Daxiehu Tang (Major Bupleurum Decoction) with added Gancao (Glycyrrhizae Radia et Rhizoma) was given for four doses to purge downward. Although pain and vomiting decreased, food intake remained absent. Then, Xiaochaihu Tang (Minor Bupleurum Decoction) was prescribed, removing Huangqin (Scutellariae Radix) and Renshen (Ginseng Radix), adding Shaoyao (Paeoniae Radix), Chenpi (Citri Reticulatae Pericarpium), Huanglian (Coptidis Rhizoma), and raw Gancao (Glycyrrhizae Radia et Rhizoma). After twenty doses, the patient recovered.
A seventeen-year-old person, poor and overworked, fell ill in November with aversion to cold and hematemesis for two or three days. The six pulses were tight and choppy. One month later, appetite decreased and epigastric fullness occurred. The physician administered Wendan Tang (Warm Gallbladder Decoction) and Zhike Tang (Citri Reticulatae Fructus Decoction). Three days later, fever developed, dry mouth without desire to drink, and phlegm in the mouth appeared. I said: This is due to contracting cold. Upon inquiry, it was found that eight days prior, the patient had crossed water in frost three or four times, had experienced sorrowful weeping in the heart, and the abdomen was hungry. Thus, Xiao Jianzhong Tang (Minor Construct the Middle Decoction) with Shaoyao (Paeoniae Radix) removed, and Jiegeng (Platycodonis Radix), Chenpi (Citri Reticulatae Pericarpium), and Banxia (Pinelliae Rhizoma) added, was given for four doses, resulting in recovery.
This refers to Danliu (Dan Tumor) mentioned in the *Neijing* (*Inner Canon*), named so because it flows and moves like cinnabar. What ancient formulas call Chiyouzhong (Red Roaming Swelling) arises because the muscles are deficient, allowing wind-toxic heat qi to invade and contend with blood and qi, causing the skin and flesh to become red and swollen. The wind follows the movement of qi and is不定 (uncertain), hence the name. Chiyouzhong is commonly called Liū (Tumor) by laypeople. It originates from wind-heat triggering Dan (cinnabar-like eruption), which flows through meridians and spreads on the body surface, appearing red like cinnabar and burning like fire. If the whole body erupts in redness, it belongs to categories such as Tianhuodan (Heaven Fire Cinnabar), with over thirty entries. The treatment method involves using Bianlian (stone lancet) according to the location to drain toxic qi; otherwise, Dan toxin enters the abdomen, and if near the heart, it causes death. However, if heart pain is present at the initial onset, Bianlian must not be used! For medication, internal drinking and external application each have their formulas, generally aiming to dissipate wind-heat, harmonize Qi, invigorate blood, and cool the muscle tissue. The *Yuanbing Shi* (*Original Treatise on Disease Causes*) also states: Chi liu (Red Flow) is heat overcoming Qi; red is the color of Fire, governed by Xianghuo (Ministerial Fire). Youzhong (Roaming Swelling) and Chi liu (Red Flow) are the same thing.
