病变部位在环跳穴，又被称为缩脚疽。其特点是皮肤颜色没有变化，局部肿胀坚硬且疼痛。外治法可用白芥子捣成粉末，用白酒酿调和后涂抹；或者使用大戟、甘遂两味药研成的细末，用白蜜调和后敷贴。内服阳和汤，每日一剂，服用四五次即可消散。病灶消散后，接着服用子龙丸或小金丹，以杜绝病根。严禁切开排脓，一旦切开必定导致腿部残疾（缩脚损疾）。
病变部位在腮部内部牙根之间，不肿不红，疼痛牵连面部骨骼，形态与贴骨疽相似。如果按照痈证来治疗，就会造成危害。初起时最容易误认为是牙疼，若多服生地、石膏等寒凉药物，会导致病情加重，腐烂至牙根，蔓延至咽喉则无法救治。应当使用二陈汤加入阳和丸煎服，或者使用阳和汤来消散病灶。如果遇到已经溃破的情况，每日早晚轮流服用阳和汤和犀黄丸。如果有死骨排出，将推车散吹入患处，隔一夜后骨头不再疼痛，会自行退出。吹药至次日，若无骨头退出，则吹入生肌散，内服保元汤加肉桂、当归、川芎。甘草宜用生甘草，待伤口愈合收功为止。
马元仪评注说：骨槽风生于牙关开合处的颊车穴。如果感觉坚硬紧贴骨骼，按压时不发热，可以服用阳和汤。
肿块大的称为恶核，小的称为痰核，与石疽初起时的症状相同。然而其寒凝程度非常严重，结聚紧密，毒根深藏，极难软化成熟。在未溃破之前，忌用清凉膏药外贴，忌投寒凉内服药，只有内服阳和汤、犀黄丸才能使其消散。也有用大田螺捣烂敷涂以消除病灶的。严禁切开，一旦切开就会导致疮口翻花突起（形成翻花疮）。可用大蟾蜍剖开腹部，刺几个孔，连同皮盖一起敷贴在患处，以拔毒并软化硬结，内服温补托毒、消痰的药物，犀黄丸足以收功。如果是孕妇，因丸药中含有麝香，故禁用。
The lesion is located at the Huantiao acupoint (GB30), also known as Suojue Ju (Shrinking-Leg Abscess). The skin color remains unchanged, but the area is swollen, hard, and painful. Externally, apply a paste made by crushing Baijiezi (Brassicae Semen Album) into powder and mixing it with fermented rice wine; alternatively, mix powders of Daji (Euphorbiae Pekinensis Radix) and Gansui (Kansui Radix) with white honey for application. Internally, administer Yanghe Tang (Warming Harmony Decoction), one dose daily; after four to five doses, the swelling may resolve. Once resolved, continue administering Zilong Wan (Dragon Pill) or Xiao Jindan (Little Golden Pill) to prevent recurrence. Incision and drainage are strictly contraindicated; cutting will inevitably lead to permanent leg disability (Suojue Sunji).
Ma Yuanyi commented: Using Yanghe Tang for Tiegu Ju (Bone-Adhering Abscess) is correct and worthy of emulation.
The lesion is located between the inner cheek and the tooth roots, presenting without swelling or redness, with pain radiating to the facial bones, resembling Tiegu Ju. If treated as a typical carbuncle (Yong), it will cause harm. In the early stage, it is easily misdiagnosed as toothache. Overconsumption of Shengdi (Rehmanniae Radix) and Shigao (Gypsum Fibrosum) can exacerbate the condition, leading to rotting of the tooth roots and spreading to the throat, which becomes incurable. Treatment should involve decocting Erchen Tang (Two-Cured Decoction) with Yanghe Wan (Harmony Pill), or using Yanghe Tang to dissipate the lesion. If ulceration has occurred, alternate between Yanghe Tang and Xihuang Wan (Rhino Horn Pill) morning and evening. If necrotic bone fragments are present, blow Tuiche San (Cart-Pushing Powder) into the wound; after one night, the bone will cease to hurt and fall out spontaneously. If no bone falls out by the next day, apply Shengji San (Flesh-Generating Powder) and internally administer Baoyuan Tang (Preserve Origin Decoction) supplemented with Rougui (Cinnamomi Cortex), Danggui (Angelicae Sinensis Radix), and Chuanxiong (Ligustici Chuanxiong Rhizoma). Use raw Gancao (Glycyrrhizae Radix et Rhizoma) until healing is complete.
Ma Yuanyi commented: Gucaofeng (Bone-Trench Wind) arises at the jaw joint opening and closing point, specifically the Jiache acupoint (ST6). If the area feels hard and adherent to the bone without heat upon palpation, Yanghe Tang may be administered.
Large nodules are called Ehe (Malignant Nuclei), while small ones are called Tanhe (Phlegm Nuclei); their initial presentation is identical to Shiju (Stone Abscess). However, the cold coagulation is severe and dense, with deep-rooted toxicity, making them extremely difficult to soften and mature. Before ulceration, cooling plasters and cooling internal medicines are contraindicated. Only internal administration of Yanghe Tang and Xihuang Wan can resolve the condition. Some practitioners use crushed large pond snails applied topically to dissipate the swelling. Incision is strictly forbidden; cutting leads to everted, flower-like granulations (Fan Hua Qi Gang). One method involves using a large toad: slit its abdomen, puncture several holes, and apply the whole toad (skin-side down) over the lesion to draw out toxicity and soften the induration. Internally, administer warming, tonifying, and detoxifying formulas that expel toxins and resolve phlegm; Xihuang Wan is sufficient for recovery. Note: For pregnant women, Xihuang Wan is contraindicated due to the presence of Shexiang (Moschus).
Ma Yuanyi commented: Ehe is difficult to ulcerate and heal; even medication often yields poor results. Strictly avoiding incision is indeed a profound truth.
