这是因为用艾火灸治疮口，导致结痂脱落后，疮内的肉片像蝴蝶一样飞出，疼痛难以忍受。这是血肉俱热的表现，属于怪症。使用朴硝、大黄各五钱，研成粉末，用水调服，一次泻下后即可痊愈。身体虚弱者忌服，可饮用真麻油一碗，并用吴茱萸末加醋调匀敷于脚心。
黑龙丹：治疗各种恶疮怪毒。因挤脓时用力过猛，导致肌肉突出，小的如饭粒，大的如梅子或菌类，翻花红赤，长久不能缩回。这名为“毒根”，是由于损伤气脉所致。人们多用降药将其腐蚀去除，但疼痛异常，体弱者难以忍受，且腐蚀后容易复发，经年累月终不痊愈。取大熟地切片烘干炒枯一两，真乌梅肉炒成炭三钱（乌梅常有以李子假冒的，使用无效，必须以自制为佳），共同研匀，碾至极细，掺在膏药上（不论何种膏药，均需用此丹以防风、升麻各一钱煎汤调搽，立即收敛）。再服用补肾的药物，之后不再发作，也是奇效。永远禁止食用鹅肉。
又一方：先用平安饼粘贴，再以阳和解凝膏（见痈疽诸方）加上贴之（没有此膏不贴亦可），一贴即可见效。
平安饼：真乌梅肉一钱，轻粉五分，和匀研至不见粉亮为度。如果太硬加少许白蜜（不可用水）。研制成膏做成饼状。病情轻的只用此饼贴之，不加阳和解凝膏亦可，或者只用乌梅肉烧存性研末候冷敷之，过夜即愈，更为快捷。
又一方：马齿苋，烧枯研末，以猪油调敷，轻者甚效。永远禁止食用鹅肉。
退管丸：庙宇内陈年旧琉璃底三钱（麸皮拌炒透）、辰砂（水飞，另研）、人指甲（麸皮拌炒透，另研），共研极细。渐次服用，远年患者服一料全愈，近年患者半料收功，虽患至二十年者亦效，屡试如神。忌食葱与有管之物百日，并戒走泄，查前痈毒宜戒便知。
This condition arises from moxibustion on the ulcer with mugwort fire; after the scab falls off, flesh pieces within the wound fly out like butterflies, causing unbearable pain. This indicates excessive heat in both blood and flesh, a strange disease. Use Natrii Sulfas (Puxiao) and Radix et Rhizoma Rhei (Dahuang), each 5 qian, ground into powder, mixed with water and taken orally. One episode of diarrhea leads to recovery. Contraindicated for those with weak constitutions; drink one bowl of pure Sesame Oil (Mahu You), and apply Evodiae Fructus (Wuzhuyu) powder mixed with vinegar to the soles of the feet.
Heilong Dan (Black Dragon Pill): Treats all kinds of malignant ulcers and strange toxins. Due to excessive force when squeezing pus, tissue protrudes, small as rice grains or large as plums or mushrooms, with red, flowering edges that fail to retract over time. This is named "toxic root," caused by damage to Qi and meridians. People often use descending/corrosive medicines to destroy it, but the pain is extreme, intolerable for the weak, and recurrence is common, leading to chronic non-healing. Take 1 liang of prepared Rehmanniae Radix (Shudihuang) sliced, dried, roasted until charred, and 3 qian of true Mume Fructus (Wumei) flesh roasted to charcoal (Note: Wumei is often counterfeited with plums, which is ineffective; homemade is best). Grind together uniformly to an extremely fine powder, sprinkle onto plaster (regardless of the type of plaster, mix this pill with Fengzi (Fangfeng) and Cimicifugae Rhizoma (Shengma), each 1 qian, decocted in water, to apply immediately for retraction). Subsequently take kidney-tonifying medicine to prevent recurrence, which is also remarkably effective. Strictly avoid goose meat.
Another prescription: First apply Ping'an Bing (Peaceful Cake), then overlay with Yanghe Jiening Gao (Yanghe Resolving Stasis Plaster) (see formulas for carbuncles and sores); if this plaster is unavailable, applying only the cake is acceptable. It works upon application.
Ping'an Bing (Peaceful Cake): 1 qian of true Mume Fructus (Wumei) flesh, 5 fen of Calomelas (Qingfen), mixed and ground until no powder shine is visible. If too hard, add a little white honey (do not use water). Process into a paste and form into cakes. For mild cases, apply only this cake without Yanghe Jiening Gao, or simply roast Mume Fructus (Wumei) until carbonized, grind into powder, let cool, and apply. Recovery occurs overnight, which is even faster.
Another prescription: Portulacae Herba (Machixian), roasted until charred and ground into powder, mixed with lard for topical application. Highly effective for mild cases. Strictly avoid goose meat.
Tuiguan Wan (Tube-Removing Pill): 3 qian of old glazed tile bottoms from temples (stir-fried thoroughly with bran), Cinnabar (Chensha, water-triturated, ground separately), and human nails (stir-fried thoroughly with bran, ground separately). Grind all together to an extremely fine powder. Administer gradually. Patients with long-standing conditions recover after one course; recent cases resolve with half a course. Even cases lasting twenty years are effective, tested repeatedly with miraculous results. Avoid green onions and tubular foods for 100 days, and avoid sexual release. Refer to precautions for previous carbuncle/toxin treatments.
Another prescription: Stir-fry Testudinis Carapax et Plastrum (Biejia), grind into powder, mix with sesame oil for topical application. The tube will be expelled; highly effective. For tubes present for many years, the effect may be slower.
Another prescription: Apply Jingsheng Sha Gao (Beijing Sand Plaster). Superficial cases expel the tube in 7-8 days, deep cases in half a month. Effective regardless of duration.
