肠痈有生于肠内者，腹内胀急，大小便牵痛如淋，转侧摇之如水声，溃后则脓从大便出
。有生肠外者，肚脐肿痛作胀，或一足弯曲，口有臭气，或脓自脐出，甚则肠穿有虫自脐中
出，势难为计。初起宜用牡丹皮散以消之，溃烂则用参 内托之剂。
牡丹皮散∶丹皮五钱，苡仁一两，栝蒌仁（去油）二钱，桃仁（去皮尖）二十粒，水煎
服。
又方∶多服六一散（见内外备用诸方），脓血从大便出，脓尽即愈。至神至稳之方也。
又方∶皂角刺一两，至少八钱，酒煎至七分，温服，脓血从大小便出而愈。不饮酒者，
水煎亦可。
又方∶大黄（炒）、朴硝各一钱，丹皮、白芥子、桃仁各二钱，空心煎服。小腹坚硬而

凡是患处皮肤颜色发红、出现肿胀疼痛，且红肿范围直径有一寸左右的，这就是痈毒。发病三到四天，脓液尚未形成时，外用洞天嫩膏贴敷，内服醒消丸，用温热的陈年黄酒送服三钱，即可停止疼痛，夜间能够入睡，第二天皮肤就会起皱，再服用药物即可完全消散。如果过了四五天即将化脓，也服用醒消丸，可使肿胀消退、疼痛停止。如果已经化脓、肿胀但尚未破溃的，用代刀散酒服即可穿破排脓，外贴洞天膏，数日即可痊愈。如果红肿范围有几寸大，位于背部正中、脑后、腰腹、腋下、阴囊等危险要害部位，早晚轮流服用五通丸和醒消丸，用败毒汤送服，皮肤起皱、疼痛停止。如果已经破溃，早晚轮流服用托毒散和醒消丸，自然会有奇效。如果红肿范围不满一寸，但也红肿的，称为疖，服用蟾酥丸、梅花点舌丹即可痊愈。这是林屋山人的经验方。

肠痈有生于肠道内部的，表现为腹部胀满急迫，大小便时牵拉疼痛如同淋证，身体转动摇晃时腹部有水声，溃烂后脓液从大便排出。有生于肠道外部的，表现为肚脐周围肿痛胀满，或者一条腿弯曲不能伸直，口中有臭气，或者脓液从肚脐流出，严重时肠道穿孔有虫从肚脐中爬出，这种情况很难处理。初起时宜用牡丹皮散来消除病邪，溃烂后则用人参类内托补益的药物。
牡丹皮散：丹皮五钱，苡仁一两，栝蒌仁（去油）二钱，桃仁（去皮尖）二十粒，水煎服。
又一方：多服六一散（见内外备用诸方），脓血从大便排出，脓液排尽即痊愈。这是非常神奇稳妥的方子。
Wherever the affected area presents with red skin, swelling, and pain, with a diameter of about one cun, this is termed carbuncle-toxin (Yong Du). If three to four days have passed since onset and pus has not yet formed, apply Dongtian Nen Gao externally, and internally administer Xingxiao Wan, taken with three qian of warm aged rice wine. This will immediately stop the pain, allow for sleep at night, and cause the skin to wrinkle the next day; subsequent doses will lead to complete resolution. If four or five days have passed and pus is about to form, Xingxiao Wan should also be administered to reduce swelling and relieve pain. If pus has formed causing swelling but the skin has not yet ruptured, Dai Dao San taken with wine will induce rupture; applying Dongtian Gao externally will result in healing within a few days. If the redness and swelling span several cun and are located in critical areas such as the mid-back, back of the head, waist, abdomen, axilla, or scrotum, Wutong Wan and Xingxiao Wan should be taken alternately morning and evening, delivered via Baidu Tang decoction; once the skin wrinkles and pain subsides, it indicates improvement. If the lesion has already ruptured, Tuodu San and Xingxiao Wan taken alternately morning and evening will yield miraculous effects. If the redness and swelling are less than one cun in diameter, it is named furuncle (Jie); Chan Su Wan and Meihua Dianshe Dan will effect a cure. These are empirical prescriptions by Linwu Shanshen.
(This formula is found in the Lung Abscess section.)
Intestinal abscess (Chang Yong) may originate inside the intestines, presenting with abdominal distension and urgency, pulling pain during urination and defecation resembling strangury (Lin), and a splashing sound upon turning or shaking the body; after ulceration, pus is discharged through the stool. It may also originate outside the intestines, presenting with swelling, pain, and distension around the umbilicus, flexion of one leg, foul breath, or pus discharging from the navel; in severe cases, intestinal perforation occurs with worms emerging from the navel, a condition that is difficult to manage. In the initial stage, Mudan Pi San should be used to dissipate the pathogen; after ulceration, tonifying internal support agents containing Ginseng (Renshen) should be employed.
Mudan Pi San: Radix Paeoniae Rubra (Danpi) 5 qian, Semen Coicis (Yiren) 1 liang, Fructus Trichosanthis (Gualou Ren) [de-oiled] 2 qian, Semen Persicae (Taoren) [skin and tip removed] 20 grains. Decoct in water and take orally.
Another prescription: Administer Liu Yi San frequently (see Formulas for Internal and External Use), allowing pus and blood to discharge through the stool; recovery occurs once the pus is exhausted. This is an extremely effective and stable formula.
Another prescription: Spina Gleditsiae Sinensis (Zaojiaoci) 1 liang, no less than 8 qian. Decoct in wine until reduced to seventy percent volume, and take warm. Recovery occurs when pus and blood discharge through urination and defecation. For those who do not consume alcohol, decocting in water is also acceptable.
Another prescription: Rhizoma et Radix Rhei (Dahuang) [stir-fried], Natrii Sulfas (Puxiao) each 1 qian; Radix Paeoniae Rubra (Danpi), Semen Mustardae Albae (Baijiezi), Semen Persicae (Taoren) each 2 qian. Decoct and take on an empty stomach. The lower abdomen is hard and hot.
