肛边生鼠乳，出在外者，时时出脓血者是也。
夫内热外虚，为风湿所乘，则生疮。所以然者，肺主气，候于皮毛；脾主肌肉。气虚则
肤腠开，为风湿所乘；内热则脾气温，脾气温则肌肉生热也。湿热相搏，故头面身体皆生疮
。其疮初如 ，须臾生汁。热盛者，则变为脓。随瘥随发。
诸久疮者，内热外虚，为风湿所乘，则头面身体生疮。其脏内热实气盛，热结肌肉，其
热留滞不歇，故疮经久不瘥。
诸疮生身体，皆是体虚受风热，风热与血气相搏，故发疮。若热风热挟湿毒之气者，则疮
痒痛 肿，而疮多汁，身体壮热，谓之恶疮也。其汤熨针石，别有正方，补养宣导，今附于
《养生方》云∶铜器盖食，汗入食，发恶疮、内疽也。
又云∶醉而交接，或致恶疮。
又云∶饮酒热未解，以冷水洗面，令人面发恶疮；轻者 。
又云∶五月五日，取枣叶三升，井华水捣取汁，浴，永不生恶疮。
又云∶井华水和粉洗足，不病恶疮。
又云∶五月一日、八月二日、九月九日、十月七日、十一月四日、十二月十三日，沐浴
，除恶疮。
《养生方·导引法》云∶龙行气，低头下视，不息十二通。愈风疥、恶疮，热不能入咽
肛门旁边长出像老鼠乳房一样的赘生物，突出在外面的，就是牡痔；经常流出脓血的就是牡痔。
因为排便时清亮的血液随之流出的，是血痔。
体内有热而体表虚弱，被风湿邪气侵袭，就会生疮。之所以这样，是因为肺主气，对应皮毛；脾主肌肉。气虚则皮肤腠理开泄，被风湿邪气侵袭；体内有热则脾气偏旺，脾气偏旺则肌肉产生热邪。湿热相互搏结，所以头面身体都生疮。这种疮起初像粟米大小，一会儿就生出汁液。热势盛的，就变成脓。病情好转后又会复发。
各种久治不愈的疮，都是体内有热、体表虚弱，被风湿邪气侵袭，导致头面身体生疮。如果脏腑内部热盛气实，热邪结聚在肌肉中，热邪停留滞留不停歇，所以疮经久不愈。
各种生在身体上的疮，都是因为体质虚弱感受风热，风热与气血相互搏结，从而引发疮疡。如果是热风挟带湿毒之气，那么疮疡会瘙痒疼痛、肿胀，且疮口多汁，身体高热，这叫做恶疮。对于这类疮疡的汤药外敷、熨烫、针刺砭石等方法，另有专门的方剂，关于补养和导引的方法，现在附载于《养生方》中：说用铜器盖住食物，汗水滴入食物中，会引发恶疮和内疽。又说：醉酒后进行房事，可能会导致恶疮。又说：饮酒后热气未散，就用冷水洗脸，会让人面部发生恶疮；轻者表现为局部红肿。又说：五月五日，取三升枣叶，用清晨第一次打的井水捣碎取汁，用来洗澡，永远不会生恶疮。又说：用井华水调和米粉洗脚，不得恶疮病。又说：在五月一日、八月二日、九月九日、十月七日、十一月四日、十二月十三日这些日子沐浴，可以消除恶疮。《养生方·导引法》中说：练习“龙行气”，低头向下看，憋气十二次。可以治愈风疥、恶疮，使热邪不能侵入咽喉。
A protruding nodule resembling a mouse's breast growing beside the anus, which frequently discharges pus and blood, is identified as *Muzhi* (Oyster Hemorrhoid).
Swelling beside the anus with the formation of sores accompanied by bleeding is identified as *Maizhi* (Vascular Hemorrhoid).
Sores appearing beside the anus, characterized by initial itching followed by pain and bleeding, are also identified as *Maizhi* (Vascular Hemorrhoid).
Hard, painful nodules beside the anus, accompanied by chills, fever, and bleeding, are identified as *Changzhi* (Intestinal Hemorrhoid).
Bright red blood flowing out during defecation is identified as *Xuezhi* (Blood Hemorrhoid).
When internal heat coexists with external deficiency, and wind-dampness pathogenic factors invade, sores will arise. The reason for this is that the Lung governs Qi and corresponds to the skin and hair; the Spleen governs muscles. When Qi is deficient, the pores (*Couli*) open, allowing wind-dampness to invade; internal heat causes the Spleen Qi to become excessive, and excessive Spleen Qi generates heat in the muscles. The interaction between damp-heat results in sores appearing on the head, face, and body. Initially, these sores resemble millet grains, but fluid soon accumulates. If heat is severe, it transforms into pus. The condition recurs after apparent recovery.
Various chronic sores result from internal heat and external deficiency, where wind-dampness invades, causing sores on the head, face, and body. If the internal organs possess excess heat and vigorous Qi, heat binds within the muscles, lingering without cessation, thus causing sores that fail to heal for a long time.
Sores arising on the body are all due to constitutional weakness combined with wind-heat invasion. Wind-heat clashes with Blood and Qi, triggering the sores. If wind-heat carries damp-toxicity, the sores become itchy, painful, swollen, and exudative, accompanied by high fever; this is termed *Echuang* (Malignant Ulcer). Regarding treatments such as herbal decoctions, moxibustion/ironing, acupuncture, and stone therapy, there are separate specific formulas. Methods of nourishment and Daoyin (guiding and pulling exercises) are appended here from the *Yangsheng Fang* (Prescriptions for Nourishing Life): It states that covering food with copper vessels allows sweat to enter the food, inducing malignant ulcers and internal abscesses. It further states that sexual intercourse while intoxicated may cause malignant ulcers. It also states that washing the face with cold water while the heat from alcohol has not yet dissipated causes malignant ulcers on the face; mild cases present with local swelling. It states that on the fifth day of the fifth lunar month, taking three sheng of jujube leaves, crushing them with well water drawn at dawn (*Jinghua Shui*), and bathing in the juice prevents malignant ulcers forever. It states that washing feet with well water mixed with powder prevents malignant ulcers. It states that bathing on the first day of the fifth month, second day of the eighth month, ninth day of the ninth month, seventh day of the tenth month, fourth day of the eleventh month, and thirteenth day of the twelfth month eliminates malignant ulcers. The *Daoyin Fa* (Guiding and Pulling Methods) in the *Yangsheng Fang* states: Practice "Dragon Moving Qi," lowering the head and looking down, holding the breath twelve times. This cures wind-scabies and malignant ulcers, preventing heat from entering the throat.
