【方歌】敦疽多生足指疼，肿色红活出血脓，血燥精竭无败色，
膏梁房劳脾肾经。
【注】此证多生于足指，而手指亦间有生者。由膏梁太过则损
脾，房劳太过则伤肾；脾既损则血生少，肾既伤则精必
竭，更兼湿热壅盛而成。初起黄粟小疱，痛如汤泼火燃
，其色红活，肿无黑晕，溃破有脓，腐无败色，此属血
脉未死之候。然此证虽无败色，亦由脏腑发出，未可视
为小毒也。法宜急服滋阴救燥、补血理脾之药，初服解
毒济生汤、六味地黄汤，溃服人参养荣汤、桂附地黄汤
。外初宜蝌蚪拔毒散涂之，将溃贴蟾酥饼，兼贴巴膏，
溃腐之后，换搽生肌玉红膏，生肌敛口。初终禁用灸法
。患者宜清心寡欲调理，庶免变证。

【方歌】甲疽多因剔甲伤，甲长侵肉破成疮，努肉高突痛难忍，
消瘀化努效非常。
【注】此证因割嵌指甲伤肉，或剔甲伤肉，或甲长侵肉，穿窄
小靴鞋，以致甲旁焮肿破烂，时津黄水，努肉高突，疼
痛难忍，不能着衣。原系好肉受伤，宜用盐汤烫洗，外
敷华陀累效散，白膏药盖贴，努肉消尽即愈。
方剂：华陀累效散
组成：乳香硵砂（各一钱）轻粉（五分）橄榄核（烧，存性，
三枚）黄丹（三分）
共研细末，香油调敷。

又方：白膏药（见溃疡门）
【方歌】敦疽多生于足趾并伴有疼痛，肿胀颜色红活，溃破后流出血液和脓液，若血色干燥、精气枯竭则无败坏之色，此病多因饮食肥甘厚味过度损伤脾脏，或房事不节过度损伤肾脏所致。
【注】此证多发生于足趾，手指间也有偶尔发生的。由于饮食肥甘厚味太过而损伤脾脏，房劳过度而损伤肾脏；脾脏既已受损则血液生成减少，肾脏既已受伤则精气必然枯竭，再加上湿热邪气壅盛而形成。初起时出现黄色粟米状小水疱，疼痛如同热水浇泼、烈火燃烧，其颜色红活，肿胀处没有黑色晕圈，溃破后有脓液，腐烂处没有败坏之色，这属于血脉尚未死亡的征候。然而此证虽然无败坏之色，也是由脏腑病变发出，不可视为小毒之症。治法应当急服滋阴润燥、补血健脾的药物，初起服用解毒济生汤、六味地黄汤，溃破后服用人参养荣汤、桂附地黄汤。外治方面，初起宜涂抹蝌蚪拔毒散，将溃破时贴蟾酥饼，同时贴巴膏，溃烂腐肉之后，更换搽涂生肌玉红膏，以生肌收敛伤口。从初起到终了都禁用灸法。患者宜清心寡欲进行调理，以免发生变证。

【方歌】甲疽多因修剪指甲时受伤引起，指甲过长侵入肌肉破损成疮，息肉高突疼痛难以忍受，消除瘀血、化解息肉效果非常显著。
【注】此证因切割嵌甲伤及肌肉，或修剪指甲伤及肌肉，或指甲过长侵入肌肉，穿着窄小的靴鞋，导致指甲旁红肿破烂，时常渗出黄水，息肉高突，疼痛难忍，不能穿鞋袜。原本是好肉受到外伤，宜用盐水烫洗，外敷华陀累效散，用白膏药覆盖贴敷，待息肉消尽即可痊愈。

[Verse] Dun Ju (Dun Carbuncle) often arises on the toes with pain; swelling is red and vibrant, discharging blood and pus. If blood is dry and essence exhausted, there is no foul color. It stems from rich diet damaging the Spleen and sexual excess injuring the Kidney.
[Note] This condition mostly occurs on the toes, occasionally on fingers. Excessive consumption of rich food damages the Spleen; excessive sexual activity injures the Kidney. Once the Spleen is damaged, blood production decreases; once the Kidney is injured, essence inevitably exhausts. Combined with abundant damp-heat, it forms. Initially, yellow millet-like small vesicles appear, with pain like scalding water or burning fire. The color is red and vibrant, swelling has no black halo, and upon ulceration, pus is discharged without foul decay. This indicates that the blood vessels have not yet died. However, although this condition lacks foul color, it originates from internal organs and should not be regarded as a minor toxicity. The treatment method requires urgently taking herbs to nourish Yin, rescue dryness, tonify blood, and regulate the Spleen. Initially, take Jiedu Jisheng Tang (Detoxification and Life-Sustaining Decoction) and Liuwei Dihuang Tang (Six-Ingredient Rehmannia Decoction). After ulceration, take Renshen Yangrong Tang (Ginseng Nourishing Harmony Decoction) and Gui Fu Dihuang Tang (Cinnamon Twig and Aconite Rehmannia Decoction). Externally, initially apply Ketou Badu San (Tadpole Detoxifying Powder), before full ulceration apply Chansu Bing (Toad Venom Cake), and simultaneously apply Ba Gao (Ba Plaster). After ulceration and necrosis, change to applying Shengji Yuhong Gao (Flesh-Regenerating Jade Red Ointment) to regenerate flesh and close the wound. Moxibustion is strictly forbidden from beginning to end. Patients should cultivate a pure heart and reduce desires for regulation, thereby avoiding complications.
Formulas: Jiedu Jisheng Tang (see Tu Ju section); Liuwei Dihuang Tang (see Facial Freckles section); Gui Fu Dihuang Tang (see Facial Cheek Ulcer section); Renshen Yangrong Tang, Ba Gao, Shengji Yuhong Gao (all see Ulcer Section); Ketou Badu San (see Swelling/Ulcer Section); Chansu Bing (i.e., Toad Venom Pill made into a cake. see Ding Chuang/Carbuncle Section).
[Verse] Jia Ju (Nail Caruncle) is mostly caused by injury from trimming nails; overgrown nails invade flesh, breaking into sores. Hypertrophic granulation tissue protrudes, causing unbearable pain; resolving stasis and reducing granulation yields extraordinary effects.
[Note] This condition results from cutting ingrown nails injuring flesh, trimming nails injuring flesh, overgrown nails invading flesh, or wearing tight boots/shoes, leading to inflammation, swelling, and breakdown beside the nail, oozing yellow fluid, with hypertrophic granulation protruding, causing unbearable pain and inability to wear footwear. Originally, healthy flesh suffers trauma. It is suitable to wash with salt water, externally apply Huatuo Lei Xiao San (Huatuo's Repeatedly Effective Powder), cover with Bai Gao Yao (White Plaster). When the granulation disappears completely, it heals.
Formula: Huatuo Lei Xiao San
Composition: Ru Xiang (Frankincense Resin) and Bi Dan (Realgar) (1 qian each), Qing Fen (Calomel) (0.5 qian), Gan Lan He (Olive Pit) (burned to retain nature, 3 pits), Huang Dan (Lead Tetroxide) (0.3 qian).
Grind all into fine powder, mix with Sesame Oil, and apply.
[Verse] Huatuo Lei Xiao San treats ingrown nails; contains Lead Tetroxide, Calomel, Frankincense, and Realgar. Olive pit burned and ground fine together, mixed thick with Sesame Oil, applied to the affected area.
Another formula: Bai Gao Yao (White Plaster) (see Ulcer Section).
