【方歌】脑后发生在督经，热结风府粟肿疼，红活易溃稠脓顺，
紫暗难溃血水凶。
【注】此证属督脉经，枕骨之下风府穴，由积热外受风邪凝结
而成。初如粟米，焮肿作疼，痛引头顶肩项，气粗鼻塞
，渐大如盘如碗。红活速溃出稠脓者顺；紫暗难溃时津
血水者逆。初起内外治法，按玉枕疽。其余内外治法，
俱按痈疽肿溃疡门。
【方歌】脑铄顶后如横木，精涸毒火上乘生，黑如灶烟牛唇硬，
木痛未腐水流清。急施桑艾法至痛，火燎刺痛属阳经，
速服仙方活命饮，若见七恶定然凶。
【注】此证先于督脉经风府穴，由阴粉枯涸，毒火乘之而生。
初起形如椒粒，坚硬紫暗，渐肿如横木，甚则上至巅顶
，下至大椎，色如灶烟，硬若牛唇。未脓皮先腐烂，时
流清水，肌肉冰冷，轻者木痛，重者毒气将陷，全不知
疼。宜急施桑柴烘法，艾壮灸法，以痛为度；速服仙方
活命饮，以舒解其毒。七日之后，不发长不生大脓者，
宜服十全大补汤救之，投补药不应者难治。若初起热如
火燎刺痛，属阳证，速服黄连消毒饮，外敷回阳玉龙膏
。此证若首尾纯见五善之证者，属顺；见七恶之证者，
逆也。其余内外治法，俱按痈疽肿溃疡门。

【方歌】脑后发（生于后脑部的痈疽）发生在督脉经，热邪结聚于风府穴，出现如粟米般的红肿疼痛，疮色红活易溃破、流出稠脓为顺证；若疮色紫暗难溃破、流出血水则为凶险之证。
【注】此病证属于督脉经，部位在枕骨之下的风府穴，由体内积热与外受风邪凝结而成。初起时像粟米大小，红肿灼痛，疼痛牵引至头顶和肩项部，呼吸气粗、鼻塞，逐渐增大如盘子或碗状。疮色红活且迅速溃破、流出稠脓的属顺证；疮色紫暗、难以溃破、时常流出津液或血水的属逆证。初起时的内治和外治方法，参照“玉枕疽”篇。其余内外治法，均参照“痈疽肿溃疡门”篇。
【方歌】脑铄（生于头顶后部的痈疽）形状像横木，因精血枯竭、毒火上乘而生，疮色黑如灶烟、坚硬如牛唇，麻木疼痛但尚未化脓时流出清稀液体。急需施行桑柴烘法和艾壮灸法，以感到疼痛为度；若如火燎般刺痛则属阳经病变，应速服仙方活命饮，若出现七恶证候则必然凶险。
【注】此病证先在督脉经的风府穴处发生，因阴精枯涸，毒火乘虚而入而生。初起时形状如椒粒，坚硬且色紫暗，逐渐肿胀如横木，严重时可上至巅顶，下至大椎穴，颜色如灶烟，坚硬如同牛唇。未化脓时皮肤先腐烂，时常流出清水，肌肉冰冷，轻者感觉麻木疼痛，重者毒气内陷，完全不知疼痛。适宜紧急施行桑柴烘法、艾壮灸法，以患者感到疼痛为限度；速服仙方活命饮，以舒缓解除其毒气。七日之后，若不生长新肉、不形成大脓的，宜服用十全大补汤来救治，若投用补药无效则难治。若初起时火热如火燎且刺痛，属阳证，应速服黄连消毒饮，外敷回阳玉龙膏。此病若从头到尾纯见五善证候的，属顺证；若见七恶证候的，属逆证。其余内外治法，均参照“痈疽肿溃疡门”篇。

[Prescription Verse] Nao Hou Fa (Abscess at the Back of the Head) occurs in the Du Meridian. Heat accumulation at Fengfu (GV16) causes millet-like swelling and pain. Reddish and vibrant lesions that easily suppurate with thick pus indicate a favorable prognosis; purplish-dark lesions that are difficult to suppurate and discharge bloody fluid indicate a ominous prognosis.
[Annotation] This condition belongs to the Du Meridian, located below the occipital bone at Fengfu (GV16). It is caused by the confluence of accumulated internal heat and external wind pathogenic factors. Initially, it resembles a millet grain, presenting with burning swelling and pain, radiating to the vertex, shoulders, and neck, accompanied by coarse breathing and nasal congestion. It gradually enlarges to the size of a plate or bowl. Lesions that are reddish-vibrant and rapidly suppurate with thick pus are considered favorable (Shun); those that are purplish-dark, difficult to suppurate, and continuously discharge serous or bloody fluids are considered unfavorable (Ni). For initial treatment, both internal and external methods should follow the guidelines for Yuzhen Ju (Abscess at the Jade Pillow). All other internal and external treatments should refer to the "Chapters on Carbuncles, Ulcers, Swellings, and Ulcerations."
[Prescription Verse] Nao Shuo (Abscess at the Crown-Back) resembles a horizontal log. It arises from the depletion of essence and blood, allowing toxic fire to ascend. The lesion appears black like soot and hard as ox lips. Before suppuration, clear fluid may flow while the area feels numb and painful. Urgently apply Sangchai Hong (Mulberry Wood Roasting) and Aizhuang Jiu (Moxa Cone Moxibustion), stopping when pain is felt. Burning pain resembling fire indicates involvement of Yang meridians; administer Xianfang Huoming Yin immediately. If Seven Evil signs appear, the prognosis is definitely poor.
[Annotation] This condition initially manifests at Fengfu (GV16) of the Du Meridian, caused by the depletion of Yin essence, allowing toxic fire to invade. Initially, it resembles a pepper grain, being hard and purplish-dark. It gradually swells like a horizontal log, potentially extending up to the vertex and down to Dazhui (GV14). The color resembles soot, and hardness resembles ox lips. Before suppuration, the skin may rot first, discharging clear fluid, with cold muscles. Mild cases present with numbness and pain; severe cases involve toxin sinking inward, resulting in complete loss of sensation. Urgently apply Sangchai Hong (Mulberry Wood Roasting) and Aizhuang Jiu (Moxa Cone Moxibustion), using pain as the indicator. Administer Xianfang Huoming Yin promptly to resolve toxicity. After seven days, if new tissue does not grow and large pus does not form, administer Shiquan Dabu Tang for rescue. If tonifying herbs are ineffective, the condition is difficult to treat. If the onset presents with burning heat and stabbing pain, it is a Yang syndrome; administer Huanglian Xiaodu Yin internally and apply Guiyang Yulong Gao externally. If the Five Good signs persist throughout the course, it is favorable; if the Seven Evil signs appear, it is unfavorable. All other internal and external treatments should refer to the "Chapters on Carbuncles, Ulcers, Swellings, and Ulcerations."
Formulas: Sangchai Hong Method, Aizhuang Jiu Method (see Volume Preface); Xianfang Huoming Yin (see Chapter on Pre-ulcerative Conditions); Shiquan Dabu Tang (see Chapter on Post-ulcerative Conditions); Huanglian Xiaodu Yin (see preceding section on Baihui Ju); Guiyang Yulong Gao (see Chapter on Pre-ulcerative Conditions).
