脑发
这种痈肿发生在头顶的泥丸宫穴。它归属于足太阳膀胱经，并与督脉共同致病。该经脉多血少气。其症状表现如同烈火燎原。脓疱炮状，大小如铜钱。颜色形态像葡萄。顶端有米粒大小的蜂房样孔洞。四周坚硬。颜色赤红的可以治愈。若出现血瘀闷乱、神志不定的则预后不良（死证）。如果八天后有脓液且可以刺破排脓的则生机尚存（生证）。
脑后发
这种痈肿也是足太阳膀胱经的病证，兼涉督脉和阳维脉。该部位多血少气。位于玉枕二穴和风府穴之间。疼痛和瘙痒程度不一，善证与恶证的表现兼杂出现。病位在表的用发汗法治疗，病位在里的用疏解法治疗。应当详细参照前文所述的方法进行治疗。
耳后发
这种疮疡是三焦经毒邪蕴结之处。发生在耳后的角孙穴和颅息穴的上下方，以及左右耳畔。这条经脉多气少血。凡是发生在此处的疮疡很难痊愈。严重时甚至会导致耳聋、咽喉肿痛、脸颊疼痛，手小指和次指（无名指）连同肩肘部都疼痛。治疗应当采用祛风降火的方法，内服疏泄或托毒外出的药物，根据具体症状进行治疗。
右鬓发
这种疮疡发生在右侧鬓角，属于足阳明胃经。该经脉多气多血。位于头维穴和下关穴的上下方。初起时像疖子一样大，随后逐渐增大。四周呈黄红色，坚硬如石头。若有脓肿形成，顶部似猪皮上的鬃眼。若患者在睡眠中出现胡言乱语、神志恍惚，并呕吐鲜血，血液流入四肢，则万无一活的可能。
左鬓发
这种疮疡发生在左侧鬓角，其涉及的经络穴位与右鬓发相同，没有差异。大抵而言，毒邪之气结聚于右侧，属于足阳明经；右侧经络内部，毒邪结聚在气分；左侧属于血分。用药时需观察表里虚实的情况，再详细辨别左右气血所属的性质来遣方用药，无不神奇有效。
Nao Fa (Hair Abscess on the Vertex)
This carbuncle occurs at the Niwan Gong acupoint on the vertex of the head. It is associated with the Foot-Taiyang Bladder Meridian and acts in conjunction with the Du Mai (Governing Vessel). This meridian is characterized by abundant blood and deficient qi. The condition presents like a fire scorching the area. The pustule resembles a cannonball in shape, about the size of a coin, with color and form similar to grapes. The apex has a honeycomb-like pore the size of a rice grain. The surrounding tissue is hard. If the color is crimson, it is treatable. If there is blood stagnation causing mental confusion and restlessness, the prognosis is fatal. If pus forms after eight days and can be lanced, survival is possible.
Naohou Fa (Hair Abscess at the Back of the Head)
This carbuncle also involves the Foot-Taiyang Bladder Meridian, along with the Du Mai (Governing Vessel) and Yangwei Mai (Yang Linking Vessel). The area is rich in blood but poor in qi. It is located between the Yuzhen (Double 9) acupoints and the Fengfu (Du 16) acupoint. Pain and itching vary, and both favorable and unfavorable signs may appear simultaneously. For exterior conditions, induce sweating; for interior conditions, use dispersing methods. Treatment should follow the detailed principles described previously.
Erhou Fa (Abscess Behind the Ear)
This ulcer is caused by toxic heat accumulation in the Hand-Shaoyang Sanjiao Meridian. It occurs above and below the Jiaosun (TE 17) and Luxi (TE 18) acupoints behind the ear, as well as on both sides of the ears. This meridian is abundant in qi and deficient in blood. Ulcers occurring here are difficult to heal. In severe cases, it may lead to deafness, swelling and pain of the throat, cheek pain, and pain in the little finger, ring finger, shoulder, and elbow. Treatment should focus on dispelling wind and suppressing fire, using internal purgatives or tonic-depurative methods, tailored to specific symptoms.
You Bin Fa (Abscess at the Right Temporal Hairline)
This ulcer occurs at the right temporal hairline and belongs to the Foot-Yangming Stomach Meridian. This meridian is abundant in both qi and blood. It is located above and below the Touwei (ST 8) and Xiaguan (ST 7) acupoints. Initially, it appears as large as a furuncle, then gradually enlarges. The surroundings are yellowish-red and hard as stone. If an abscess forms, the surface may resemble pig bristle pores. If the patient experiences delirium and trance during sleep, vomiting fresh blood that flows into the limbs, death is inevitable.
Zuo Bin Fa (Abscess at the Left Temporal Hairline)
This ulcer occurs at the left temporal hairline, involving the same meridians and acupoints as the You Bin Fa without difference. Generally, toxic qi binds on the right side, which belongs to the Foot-Yangming Meridian; on the right side of the meridians, toxin binds in the Qi level; the left side belongs to the Blood level. When prescribing medication, one must observe the exterior-interior and deficiency-excess patterns, then carefully distinguish the Qi and Blood involvement on the left and right sides to guide treatment, achieving miraculous results.
