申斗垣曰∶凡痈疽杖毒，及杨梅结毒， 疮、便毒、疔疮等，内多有死肉停蚀好
肉，若痛难禁，若不早去，愈加腐烂，正谓之恶如野狼虎，毒似蛇蝎，有伤性命，恐
致不救。当视其缓急，死肉大小，或以针刀割去，缓以腐肉绽子，或末药膏药贴之，
以平为期，后上生肌长肉等药上之，内服大补汤丸等剂而愈。世多庸俗，只知敷贴
长肉生肌等药为神，殊不知有死肉为害，反加腐烂是也。如不去净，亦不能得愈，宜
熟玩之。（《启玄》）
程山龄曰∶煎好猪蹄汤，绢片滤去渣，俟汤半温，再用方盘盛汤，安放疮下，随
以软绢淋汤疮上，并入孔内，轻手捺尽内脓，庶败腐宿脓随汤而下，以净为度；再
以软帛叠成七八重，勿令太干，带汤覆于疮上，以手轻盈旋按片时，帛冷再换，如
此洗六七次，自然痛减毒消，洗时避风及人口气。（《十法》）
冯鲁瞻曰∶夫痈疽已溃，日用猪蹄汤淋洗，将愈之际，三日一次。（《锦囊》）
王肯堂曰∶溃疡宜洗，若非行补接之药，以实其内，窃恐淋洗有一时之快，少
顷恐病体自觉疲惫，有不耐烦之意，非虚而何？可不先议补接乎？（《准绳》）
又曰∶洗漏疮，当用干艾作汤，投白矾末二三钱，洗疮口，盖人血气冷，必假
艾力以助阳，而艾性亦能杀虫也。（此疮漏不可遽合，结毒实虫所为之者。）
陈良甫曰∶若痈久不合，其肉白而脓少者，此气血俱虚，不能潮运，而疮口冷
涩也。每日用艾叶一把煎汤，避风热洗，及
烧松香烟熏之，或用猪蹄汤洗之，更以神异膏贴之，必须守禁调理，否则不效。
唐元祯曰∶凡背疮，腐肉不去，不用刀割，用降香煎汤，不可用手洗，将汤入
酒壶内淋于疮上，以新羊毛笔扫之，拭干，再用巴豆炒黑，捣成膏，搽数次，腐肉自去，新肉自生。
申斗垣说：凡是痈疽、杖伤毒邪，以及杨梅结毒、恶疮、便毒、疔疮等病症，内部多有死肉停留腐蚀好肉。如果疼痛难以忍受，若不早点去除，会更加腐烂，这正是所说的“恶如野狼虎，毒似蛇蝎”，会伤害性命，恐怕导致无法救治。应当视其缓急程度和死肉大小，有的用针刀割去，有的用腐肉绽子（一种去腐药），或用末药膏药贴敷，以平复为度，之后再使用生肌长肉等药物，内服大补汤丸等剂型即可痊愈。世间多庸俗之人，只知道敷贴长肉生肌等药为神效，却不知道有死肉为害，反而加重腐烂。如果不彻底去除，也不能痊愈，宜仔细研读体会。（出自《启玄》）
程山龄说：煎好猪蹄汤，用绢片滤去渣滓，待汤半温时，再用方盘盛汤，安放在疮口下方，随即用软绢蘸汤淋洗疮面，并深入孔洞内，轻手按压排尽内部脓液，使败腐宿脓随汤流出，以干净为度；再用软帛叠成七八层厚，不要太干，带着汤覆盖在疮上，用手轻轻旋转按压片刻，帛变冷再更换，如此清洗六七次，自然疼痛减轻毒邪消退，清洗时要避风及避免人口气直吹。（出自《十法》）
冯鲁瞻说：痈疽已经溃破，日常用猪蹄汤淋洗，将要痊愈之际，改为三天一次。（出自《锦囊》）
王肯堂说：溃疡适宜清洗，如果不是先行补接之药以充实内部，恐怕淋洗有一时之快，稍后恐怕病体自觉疲惫，有不耐烦之意，这不是虚证又是什么？怎能不先商议补接呢？（出自《准绳》）
又说：清洗漏疮，当用干艾煮汤，投入白矾末二三钱，清洗疮口，因为人体血气寒冷，必须借助艾力以助阳，而艾性也能杀虫。（此漏疮不可急于闭合，结毒实为虫所致。）
陈良甫说：如果痈久不愈合，其肉色白且脓少者，这是气血俱虚，不能潮运，而疮口冷涩。每日用艾叶一把煎汤，避风热清洗，并用烧松香烟熏之，或用猪蹄汤清洗，更以神异膏贴敷，必须遵守禁忌调理，否则无效。
唐元祯说：凡是背疮，腐肉不去，不用刀割，用降香煎汤，不可用手洗，将汤倒入酒壶内淋于疮上，用新羊毛笔扫之，拭干，再用巴豆炒黑，捣成膏，搽数次，腐肉自去，新肉自生。
Shen Douyuan stated: In cases of carbuncle and ulcer (Yong Ju), trauma-induced toxicity, yaws condensation toxicity (Yangmei Jiedu), malignant sores, groin abscesses (Biandu), and carbuncles (Dingchuang), dead flesh often remains and corrodes healthy tissue. If the pain is unbearable and not removed early, it will become increasingly putrid. This is described as "malignant as wild wolves and tigers, toxic as snakes and scorpions," endangering life and potentially leading to untreatable conditions. One should assess the urgency and size of the dead flesh; some may be excised with needles or knives, while others may be treated with rotting flesh extractors (Furou Zhanzi) or powdered medicinal plasters, aiming for a level surface. Subsequently, medicines promoting tissue regeneration (Shengji Zhangrou) should be applied, along with internal administration of major tonifying decoctions and pills for recovery. The common people often mistakenly believe that applying tissue-regenerating plasters alone is miraculous, unaware that retained dead flesh causes harm and exacerbates putrefaction. If not thoroughly removed, healing cannot occur; this point warrants careful study. (From *Qixuan*)
Cheng Shanling stated: Boil pig trotter soup, filter out the dregs using silk gauze, and when the soup is half-warm, place it in a square basin positioned beneath the sore. Then, use soft silk to ladle the soup over the wound surface and into any cavities, gently pressing to expel internal pus, allowing necrotic matter and old pus to drain away with the soup until clean. Next, fold soft cloth into seven or eight layers (not too dry), soak it in the soup, and cover the wound. Gently press and rotate by hand for a moment; replace the cloth when it cools. Repeating this washing six or seven times naturally reduces pain and eliminates toxicity. During washing, avoid wind and human breath. (From *Shifa*)
Feng Luzhan stated: For open carbuncles and ulcers, daily washing with pig trotter soup is recommended; as healing approaches, reduce frequency to once every three days. (From *Jinnang*)
Wang Kentang stated: Ulcers are suitable for washing. However, if one does not first administer tonifying and connecting herbs to strengthen the interior, the temporary relief from washing may soon lead to fatigue and irritability in the patient, indicating deficiency. Is it not necessary to discuss tonification and connection first? (From *Zhunsheng*)
He also stated: To wash fistula sores (Lou Chuang), boil dried mugwort (Ai Ye) in water, add two or three qian of alum powder (Baifan Mo), and wash the sore opening. Since human blood and qi tend to be cold, mugwort's warming properties assist yang, and its nature can also kill parasites. (Note: Fistulas should not be closed hastily; condensation toxicity is indeed caused by parasites.)
Chen Liangfu stated: If a carbuncle fails to heal for a long time, with white flesh and scant pus, this indicates deficiency of both qi and blood, failing to circulate, resulting in a cold and astringent sore opening. Daily, boil a handful of mugwort leaves in water, wash avoiding wind and heat, fumigate with smoke from burning pine wood, or wash with pig trotter soup, then apply Shenyi Plaster. Strict adherence to dietary and lifestyle restrictions is required, otherwise efficacy will be lacking.
Tang Yuanzhen stated: For back carbuncles, if necrotic flesh is not removed, do not use knife excision. Instead, decose agarwood (Xiang) in water. Do not wash with hands. Pour the decoction into a wine pot and pour it over the sore. Sweep with a new wool brush, wipe dry, then apply a paste made from blackened and pounded bitter almond seeds (Badou). Applying this several times allows necrotic flesh to fall off and new flesh to grow naturally.
