痈疽（疮疡肿毒）并发发痉，属于败坏之证。其症状类似破伤风，表现为牙关紧闭、四肢强直僵硬、腰背向后反折、肢体抽搐。若有汗出称为柔痉（用栝楼桂枝汤治疗）。若手足逆冷，则加用桂枝、附子。倘若误诊为中风，则会加速病情恶化导致死亡。
疮口溃烂后未能愈合，误入皂角汁毒素，以及一切污秽毒水，再次导致患处肿胀疼痛。先用藿香汤清洗洁净，用白矾、桃丹（炒制）等量研成细末撒在患处，或者将乌梅嚼烂涂抹也可。如果患者感到疼痛深入骨髓，烦闷昏厥，担心毒气内攻，则用马齿苋五钱，用酒煎煮饮用，直至醉倒以取疗效。
夏季各种疮疡溃烂，因疏忽未加洗涤，积聚脓液污秽，致使苍蝇聚集产卵生蛆。用皂矾水飞过的粉末掺敷患处，蛆虫即刻化为水。治疗方法也相同。
巅顶，（即头顶，俗称天灵盖。）足厥阴肝经与督脉交会于巅顶，足太阳膀胱经交会于巅顶，足少阳胆经交会于巅顶。
脑，（头骨中的髓质。）足少阴肾经属海髓，足太阳膀胱经络连脑角，（额部两侧棱角处），足少阳经皆直上头角。
额颅，（发际之下，两眉之上是也，亦名颡。）足阳明胃经至额颅，手阳明大肠经上达额左角，手少阳三焦经结于额上角，足太阳膀胱经下抵额部。
头发，由足少阴肾经所主。
百会疽，又名玉顶发，生于巅顶正中的百会穴。佛顶疽，生于囟门之前。勇疽，又名脑发疽，生于眼睛上方。玉枕疽，生于脑后玉枕骨上四寸半，靠近脑户穴。脑后发，生于玉枕之下的风府穴。透脑疽，生于百会穴之前，囟门之际。侵脑疽，生于透脑疽前侧下方的五处穴。脑铄，生于脑后风府穴，两条大筋中间的穴位中央。发疽，生于发内的囟门上，小儿患此病名为鳝拱头。均按照痈疽的常规法则进行治疗。
Carbuncles and sores (ulcerative swellings) complicated by spasms constitute a critical, deteriorating condition. The presentation resembles tetanus, characterized by trismus (lockjaw), rigidity of the four limbs, opisthotonos (backward arching of the back), and convulsions of the limbs. If sweating is present, it is termed "Rou Jing" (Soft Spasm); treat with *Gualou Guizhi Tang* (Trichosanthes Root and Cinnamon Twig Decoction). If there is coldness in the hands and feet, add *Guizhi* (Cinnamomi Ramulus) and *Fuzi* (Aconiti Lateralis Radix Praeparata). Misdiagnosing this as wind-stroke will rapidly accelerate the danger to life.
If the ulcer has not healed after rupture, and poison from soapberry juice or any other filthy toxic water enters the wound, it causes swelling and pain at the affected site. First, wash clean with *Huoxiang Tang* (Agastache Decoction). Then, apply an equal proportion of finely powdered *Baifan* (Alum) and *Taodan* (Red Lead Oxide, stir-fried) to the area, or chew *Wumei* (Mume Fruit) until soft and apply it topically. If the patient experiences bone-penetrating pain, restlessness, and fainting, suspecting internal attack by toxin, use 5 qian of *Machixian* (Portulacae Herba), decocted in wine for oral administration; induce drunkenness to achieve efficacy.
In summer, various ulcers that have ruptured and were neglected without cleaning may accumulate pus and filth, attracting flies to gather and lay eggs, producing maggots. Apply powder made from *Zaofan* (Chalcanthite) processed by water levigation to the lesion; the maggots will immediately dissolve into liquid. The treatment method is the same.
The vertex (top of the head, commonly known as Tianlinggai): The Foot-Jueyin Liver Meridian and the Du Mai (Governor Vessel) intersect at the vertex; the Foot-Taiyang Bladder Meridian intersects at the vertex; the Foot-Shaoyang Gallbladder Meridian intersects at the vertex.
The brain: The marrow within the skull. The Foot-Shaoyin Kidney Meridian is associated with the sea of marrow; the Foot-Taiyang Bladder Meridian connects to the brain corners (the angular regions on both sides of the forehead); the Foot-Shaoyang meridians ascend directly to the temporal angles.
The frontal cranium (below the hairline, above the two eyebrows, also called Sang): The Foot-Yangming Stomach Meridian reaches the frontal cranium; the Hand-Yangming Large Intestine Meridian ascends to the left corner of the forehead; the Hand-Shaoyang Sanjiao Meridian knots at the upper corner of the forehead; the Foot-Taiyang Bladder Meridian descends to the forehead.
Hair: Governed by the Foot-Shaoyin Kidney Meridian.
Baihui Ju (Abscess at Baihui), also named Yuding Fa, arises at the Baihui point (GV20) in the exact center of the vertex. Foding Ju arises anterior to the fontanelle. Yong Ju, also named Naofa Ju, arises above the eyes. Yuzhen Ju arises 4.5 cun above the posterior aspect of the head on the Yuzhen bone, near the Naohu point (GV16). Naohou Fa arises below the Yuzhen bone at the Fengfu point (GV16). Tou Nao Ju arises anterior to the Baihui point, at the junction of the fontanelle. Qin Nao Ju arises five shi points anterior-lower to the side of the Tou Nao Ju. Nao Shuo arises at the Fengfu point (GV16) on the posterior neck, in the center between the two major tendons. Fa Ju arises within the hair at the fontanelle; when occurring in infants, it is named Shan Gong Tou. All are treated according to the standard protocols for carbuncles and sores.
