《千金方》治久疽方∶
取鲫鱼，破其腹，勿损肠脬，纳上白盐末，以针缝合，于铜器中火煎令干，末，着疮中，
无脓者以猪脂和敷，小疼痛，勿怪也。
《令李方》治久痈疽漏夕药散方∶
夕药（三分） 大黄（三分） 白蔹（三分） 莽草（二分）
凡四物，冶合下筛，和调之，以酒服半钱匕，日二。不知可稍增至方寸匕。
《病源论》云∶缓疽者，由寒气客于经络，致营卫凝涩，气血壅结所成。其寒气盛者，
则肿结痛深，而回回无头尾，大者如拳，小者如桃李，冰冰与皮肉相亲着。热气少，其肿与
肉色相似，不甚赤，积日不溃，久乃变紫黯色，皮肉俱烂，如牛领疮，渐至通体青黯，不作
头，而穿溃脓出是也。以其结肿积久，而其肉腐坏迟，故名缓疽；亦名肉色疽也。
《短剧方》治缓疽方∶
初作宜服五香连翘汤， 去血，以小豆薄涂之，其间数以 针去血。又敷之取消良也，
不消色未变青KT 者，以练石薄敷之。若失时，不得消已烂者，犹服五香连翘汤及漏芦汤
下之，随热多少投方也。外以升麻汤 洗之，敷升麻膏。若生臭恶肉者，可以单行一物白
茹散敷之，青黑肉尽便敷也。好肉熟生但敷升麻膏良，肉不生敷单行一物黄 散也。若敷白
茹散，积日青黑恶肉不尽者，可以柒头赤皮 茹散。取半钱匕和杂三大钱匕白 茹散中合，
冶之，稍以敷之。恶肉去尽还淳用白 茹散也，视好肉欲生可敷黄 散也。
白 茹散、柒头 茹散、黄 散。
上三方并一物单行，随多少舂下筛用耳。
《千金方》治疗久不愈合的疽疮的方子：
取鲫鱼，剖开其腹部，不要损伤肠道和膀胱，放入白色盐末，用针缝合，在铜器中用火煎至干燥，研成粉末，撒在疮口中。
没有脓液的，用猪脂调和后敷贴，会有轻微疼痛，不要感到奇怪。
《令李方》治疗长期不愈的痈疽漏管的外用药散方：
夕药（三分） 大黄（三分） 白蔹（三分） 莽草（二分）
以上四味药，研磨混合过筛，调和均匀，用酒送服半钱匕量，每日两次。如果效果不明显，可以稍微增加到一方寸匕量。
《诸病源候论》说：缓疽，是由于寒气侵入经络，导致营卫之气凝滞涩阻，气血壅结而形成的。寒气盛行的，则肿胀结聚、疼痛深重，且看不出明显的头尾，大的像拳头，小的像桃李，冰凉并与皮肉紧密相连。热气较少，其肿胀与肌肉颜色相似，不太红，经过多日不溃破，很久才变成紫暗色，皮肉全部腐烂，像牛颈部的疮，逐渐发展到全身青暗，不形成脓头，而是穿破溃烂流出脓液。因为结肿积聚日久，而肌肉腐烂缓慢，所以名叫缓疽；也叫肉色疽。
《短剧方》治疗缓疽的方子：
初起时适宜服用五香连翘汤，以去除瘀血，用小豆薄涂患处，其间多次用针刺去瘀血。另外敷贴取消良（药名）也很好，如果颜色未变青黑的，用练石薄敷。如果错过时机，无法消除且已经腐烂的，仍然服用五香连翘汤及漏芦汤来攻下，根据热邪的多少投予相应的方剂。外用升麻汤清洗，敷贴升麻膏。如果长出恶臭腐肉，可以用单味药组成的白茹散敷贴，直到青黑色的恶肉完全去除后再停止。好肉生长成熟但尚未愈合时，仅敷贴升麻膏即可，如果肌肉不生肌，则敷贴单味药组成的黄散。如果敷贴白茹散，经过多天青黑色恶肉仍未除尽的，可以使用柒头赤皮茹散。取半钱匕量，混合三大钱匕量的白茹散中一起研磨，稍微敷贴其上。恶肉去除干净后恢复纯净状态，再用白茹散，观察好肉将要生长时可敷贴黄散。
白茹散、柒头茹散、黄散。
以上三方均为单味药单独使用，根据用量捣碎过筛后使用罢了。
The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) provides a prescription for treating chronic ulcers (chronic, non-healing sores):
Take a crucian carp, split its abdomen without damaging the intestines or bladder, insert powdered white salt, suture it with a needle, and boil it to dryness in a copper vessel. Grind into powder and apply into the wound.
If there is no pus, mix with lard (pig fat) and apply; slight pain may occur, do not be alarmed.
The *Ling Li Fang* provides an external powder prescription for treating long-standing carbuncles, ulcers, and fistulas:
Hesperidum (Xiyao, 3 fen) Rhizoma et Radix Rhei (Dahuang, 3 fen) Rhizoma Belamcandae (Bailian, 3 fen) Herba Dracocephali Moldavicae (Mangcao, 2 fen)
These four ingredients are ground together and sifted. Mix well and take half a qianbi dose mixed with wine, twice daily. If ineffective, the dose may be slightly increased to one fangcunbi dose.
The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: Huanju (Slow ulcer) arises from cold pathogen invading the meridians and collaterals, causing stagnation and obstruction of Ying (Nutritive) and Wei (Defensive) Qi, resulting in congestion and accumulation of Qi and Blood. When cold pathogen is severe, swelling and nodules form with deep pain, lacking distinct head or tail; large ones resemble fists, small ones resemble plums or peaches, feeling icy cold and adhering closely to the skin and flesh. With less heat, the swelling resembles muscle color, is not very red, does not suppurate after many days, and only later turns purplish-dark. The skin and flesh rot completely, resembling neck sores of cattle, gradually spreading to turn the whole body dark cyan, forming no head but instead breaking open to discharge pus. Because the nodule accumulates for a long time and tissue necrosis is slow, it is named Huanju; also called Rouseju (Flesh-colored ulcer).
The *Duanju Fang* provides a prescription for treating Huanju:
At the initial stage, it is suitable to take Wuxiang Liaoqiao Tang (Five-Spice Forsythia Decoction) to remove blood stasis, apply thin layer of Adzuki bean paste, and repeatedly prick with needles to drain blood during the process. Additionally, applying Xiaoxiaoliang is also effective; if the color has not turned dark cyan, apply thin layer of Lianshi (Calcined Stone). If treatment is delayed and cannot resolve, or if already ulcerated, continue taking Wuxiang Liaoqiao Tang and Loulu Tang to purge, prescribing according to the degree of heat. Externally wash with Shengma Tang (Cimicifuga Decoction) and apply Shengma Gao (Cimicifuga Ointment). If foul-smelling necrotic flesh grows, apply Bairu San (White Ru Powder) alone until all dark cyan necrotic tissue is removed. For healthy granulation tissue that is mature but not yet healed, apply Shengma Gao alone; if flesh fails to regenerate, apply Huang San (Yellow Powder) alone. If applying Bairen San and dark cyan necrotic tissue remains after many days, use Qitou Chipi Ru San (Seven-Head Red-Skin Ru Powder). Take half a qianbi dose and mix with three large qianbi doses of Bairen San, grind together, and apply sparingly. Once all necrotic tissue is removed and the area returns to purity, resume using Bairen San; observe when healthy flesh is about to grow and apply Huang San.
Bairen San, Qitou Ru San, Huang San.
All three prescriptions consist of single herbs used individually; crush and sift according to the required dosage.
