脑痈发于泥丸宫，在头顶之上，倘色如葡萄之紫，疮口不一，或如碎粟，四围坚硬，疮
顶色红赤不黑，是为阳痈，尚可医疗。若色紫而黑暗无光，神情闷乱，不知人事者，是为阴
症，十死其十，百死其百。必须以五日之前以火剂煎饮，或尚有生机，过此则生死难言矣。
方用∶
金银花八两 玄参三两 黄 四两 麦冬三两 人参二两
先用水十大碗，将金银花煎汤，再煎前药二碗，一日服二次，连服四日，其痈渐愈。改
用十全大补汤，重四两与之，又改用八味地黄汤，恣其酣饮，可获全愈，是为九死一生之治
法。
此外，可于未溃败时，或用∶
川芎一两 玄参二两 金银花二两 山茱萸一两 麦冬一两 贝母三钱 蔓荆子二钱
用水三大碗，煎服之，即消，最多两剂痊愈。
脑后痈生于玉枕部，亦有阳症阴症之别。其为患虽较脑痈为轻，然医不得法。即腐烂落
头而死，故有落头疽之名。凡属阳症，其形高突红肿，可用∶
金银花二两 蒲公英一两 生草三钱
用水三碗煎八分，服下。未破者，一剂即消；已破者，必须三服，始脓尽肉生。
若系阴症，则其旁必有无数小疮，先痒后痛，遂至溃烂，肿而不甚高突，色必黑暗，身
体沉重困倦欲卧，呻吟无力。可用∶
人参一两 生黄 一两 当归一两 金银花二两 白芥子三钱 肉桂一钱 炒白术一两
用水煎服，一剂血止，二剂肉生，三剂口小，四剂皮合，又二剂痊愈。
脑痈发生在泥丸宫，位于头顶上方。如果疮色像葡萄一样紫暗，疮口不止一个，有的像碎谷粒，四周坚硬，疮顶颜色红赤但不发黑，这属于阳痈，还可以治疗。如果颜色紫暗且黑暗无光，神情烦闷混乱，不知人事的，这属于阴症，十个人中死十个，一百个人中死一百个。必须在发病前五天内用火剂煎煮服用，或许还有生机，过了这个时间则生死难料了。
方剂组成：
金银花八两，玄参三两，黄芪四两，麦冬三两，人参二两。
先用十大碗水，将金银花煎成汤，再加入其余药物煎至两碗，每日服用两次，连续服用四天，痈肿逐渐痊愈。随后改用十全大补汤，每次重四两给予患者，接着改用八味地黄汤，让其尽情饮用，可以获得完全治愈，这是针对九死一生重症的治疗方法。
此外，在痈肿尚未溃烂败坏时，也可以使用以下方剂：
川芎一两，玄参二两，金银花二两，山茱萸一两，麦冬一两，贝母三钱，蔓荆子二钱。
用三大碗水煎服，即可消除，最多两剂就能痊愈。
脑后痈生长在玉枕部，也有阳症和阴症的区别。虽然其危害比脑痈轻，但如果医治不得法，就会导致腐烂、头部脱落而死，所以有“落头疽”这个名字。凡是属于阳症的，形状高突红肿，可以使用以下方剂：
金银花二两，蒲公英一两，生甘草三钱。
用水三碗煎至八分满，服用。未破溃的，一剂即可消除；已破溃的，必须服用三剂，才能脓尽肉生。
如果是阴症，那么旁边必然有无数小疮，先痒后痛，直到溃烂，肿胀但不怎么高突，颜色必定黑暗，身体沉重困倦想睡觉，呻吟无力。可以使用以下方剂：
人参一两，生黄芪一两，当归一两，金银花二两，白芥子三钱，肉桂一钱，炒白术一两。
用水煎服，一剂血止，二剂肉生，三剂疮口变小，四剂皮肤愈合，再服两剂痊愈。
Nao Yong (Brain Abscess) occurs in the Niwan Palace, located on the top of the head. If the color is purple like a grape, with multiple sores, some resembling broken millet grains, and the surrounding area hard, while the top of the sore is red but not black, this is classified as Yang Nao Yong (Yang-type Brain Abscess), which is still treatable. If the color is purple, dark, and lusterless, accompanied by mental confusion and loss of consciousness, this is classified as Yin Zheng (Yin Syndrome). The mortality rate is extremely high; ten out of ten or one hundred out of one hundred may die. Treatment must begin with decoction of Huo Ji (Fire Agent) within five days before onset; otherwise, survival is uncertain.
Prescription:
Jinyinhua (Lonicerae Japonicae Flos) 8 liang, Xuanshen (Scrophulariae Radix) 3 liang, Huangqi (Astragali Radix) 4 liang, Maidong (Ophiopogonis Radix) 3 liang, Renshen (Ginseng Radix) 2 liang.
First, use ten large bowls of water to decoct Jinyinhua into a soup. Then add the remaining herbs and decoct until two bowls remain. Take twice daily for four consecutive days, during which the abscess will gradually heal. Subsequently, switch to Shiquan Dabu Tang (Decoction for Perfect Tonicity) at a dose of four liang, followed by Sibai Dihuang Wan (Eight-Ingredient Rehmannia Pill) decocted, allowing the patient to drink freely to achieve full recovery. This is a treatment method for critical cases with only one chance of survival out of nine.
Additionally, before the abscess ulcerates and deteriorates, the following prescription can be used:
Chuanxiong (Ligustici Chuanxiong Rhizoma) 1 liang, Xuanshen (Scrophulariae Radix) 2 liang, Jinyinhua (Lonicerae Japonicae Flos) 2 liang, Shanzhuyu (Corni Fructus) 1 liang, Maidong (Ophiopogonis Radix) 1 liang, Beimu (Fritillariae Thunbergii Bulbus) 3 qian, Manjingzi (Vittaginis Fructus) 2 qian.
Decoct in three large bowls of water and take orally. It will resolve immediately, with recovery expected in no more than two doses.
Naohou Yong (Posterior Neck Abscess) arises in the Yuzhen region. It also presents as either Yin or Yang syndrome. Although less severe than Nao Yong, improper medical treatment can lead to rotting and decapitation, hence the name Luotou Ju (Head-Dropping Carbuncle). For Yang syndrome, characterized by high, protruding, red, and swollen lesions, the following prescription is applicable:
Jinyinhua (Lonicerae Japonicae Flos) 2 liang, Pugongying (Taraxaci Herba) 1 liang, Sheng Gancao (Glycyrrhizae Radix et Rhizoma Preparata) 3 qian.
Decoct in three bowls of water until reduced to eighty percent volume, then administer. For unruptured lesions, one dose resolves it; for ruptured lesions, three doses are required until pus is exhausted and flesh regenerates.
If it is Yin syndrome, there will inevitably be numerous small sores nearby, starting with itching followed by pain, leading to ulceration. The swelling is not highly protruding, the color is dark, the body feels heavy and lethargic with a desire to sleep, and moaning is weak. The following prescription is applicable:
Renshen (Ginseng Radix) 1 liang, Sheng Huangqi (Astragali Radix) 1 liang, Danggui (Angelicae Sinensis Radix) 1 liang, Jinyinhua (Lonicerae Japonicae Flos) 2 liang, Baijiezi (Sinapis Semen) 3 qian, Rougui (Cinnamomi Cortex) 1 qian, Chao Baizhu (Atractylodis Macrocephalae Rhizoma Preparatum) 1 liang.
Decoct in water and take orally. Bleeding stops after one dose, flesh regenerates after two doses, the wound shrinks after three doses, skin closes after four doses, and full recovery is achieved after two additional doses.
