脑后部位发生痈肿，归属于太阳膀胱经的积热，或是湿毒上壅，或者是肾虚导致阴液枯竭。初期肿痛剧烈，伴有烦躁口渴，脉象洪大且数。如果肿块坚硬尚未化脓，适宜采用除湿解毒的方法。疼痛剧烈属于湿热证，适宜使用黄连消毒饮之类的方剂。疼痛剧烈或者不疼痛的，可以隔蒜灸，并服用真人活命饮（方剂见前文）。如果出现便秘，说明邪气在体内，适宜泻下。疼痛不剧烈，且不化脓的，适宜用四君子汤加入当归、黄芪进行补托。脓已成且疼痛的，针刺排脓兼用托里法。脓多而不收敛的，大补气血。喜欢喝冷水的，适宜泻火。毒盛且便秘的，使用防风通圣散（方剂见风门章节）。此证也可以使用骑竹马灸法。
主方：黄连（酒制）、羌活、生地、当归身、连翘、黄芪、黄柏、独活、防风、藁本、防己、苏木、陈皮、桔梗（各一钱），泽泻（七分），知母（酒炒，四分），人参、甘草（各五分）。以上药材用水煎煮成汤，加入少许酒，服用。
这种病症多因怒气引发，或者是肝、胆、三焦的风热，以及血虚所致。局部肿大疼痛，伴有寒战发热和身体拘急，先服用加减败毒散，以发散表邪。如果是因怒动肝火引起的，用小柴胡汤加入连翘、桔梗、金银花，随后服用活命饮之类的方剂。如果不化脓也不溃破，适宜托里。如果化脓且疼痛剧烈，托里解毒。脓已成但未破溃，针刺排脓。脓溃后不收敛，大补气血。
主方（清肝）：柴胡、山栀（炒，各钱半）、黄芩、川芎、人参（各一钱）、连翘、桔梗（各八分）、甘草（五分）。以上药材用水煎煮，饭后服用。
疽发于胸部，初起如黄豆大小，皮肤颜色不变。如果冷气攻心，出现精神恍惚、呕吐冷痰、毒瓦斯内陷、腹胀等症状，则预后不良致死。如果出现心烦身躁、肌肤如火般灼热、出汗、嘴唇焦裂、渴望饮用冷水，这是其症状表现。急需服用活命饮加入黄连、桔梗，以及夺命丹之类的方剂，通过发汗或泻下的方法治疗。出现恶证时，使用犀角解毒汤。疽发于膺部（胸部两侧高处），称为臆疽。颜色发青，伴有寒热，治疗方法同上。
在心窝上方两乳之间发生的，称为膻中疽，发于气之海（膻中穴所在），是阴阳分布之处，由脏腑不和、七情郁结而成，适宜用活命饮加入紫苏、薄荷发汗，再配合选用紫金锭。
A carbuncle (ju, 疽) occurring at the back of the head belongs to accumulated heat in the Taiyang Bladder Meridian (Taiyang Bladder Channel), or upward congestion of damp-toxin, or depletion of Yin fluids due to Kidney deficiency. In the initial stage, swelling and pain are severe, accompanied by irritability, thirst, and a surging and rapid pulse. If the swelling is hard and pus has not formed, it is appropriate to employ methods for dispelling dampness and resolving toxin. Severe pain indicates a Damp-Heat syndrome, for which Huanglian Xiaodu Yin (Coptis Decoction for Resolving Toxin) or similar formulas should be used. For cases with severe pain or no pain, garlic-separated moxibustion may be applied, along with administration of Zhenren Huoming Yin (True Person's Life-Saving Decoction) (see formula previously mentioned). If constipation occurs, indicating pathogenic factors within, purgation is indicated. For mild pain without pus formation, Sijunzi Tang (Four Gentlemen Decoction) added with Danggui (Angelicae Sinensis Radix) and Huangqi (Astragali Radix) should be used for supporting the interior. Once pus has formed with pain, acupuncture should be employed alongside interior-supporting methods. For excessive discharge that fails to heal, substantial tonification of Qi and Blood is required. Preference for cold drinks indicates Fire excess, requiring fire-purging methods. For severe toxicity with constipation, Fangfeng Tongsheng San (Saposhnikovia Powder for Unblocking and Safeguarding) (see Wind Gate section) is indicated. This condition may also be treated with Qizhuma Moxibustion (Bamboo-Horse Moxibustion).
Main Formula: Huanglian (Coptidis Rhizoma, processed with wine), Qianghuo (Notopterygii Rhizoma et Radix), Shengdi (Rehmanniae Radix), Dangguishen (Radix Angelicae Sinensis, root part), Lianqiao (Forsythiae Fructus), Huangqi (Astragali Radix), Huangbai (Phellodendri Cortex), Duhuo (Angelicae Pubescentis Radix), Fangfeng (Saposhnikoviae Radix), Gaoben (Ligustici Chuanxiong Rhizoma), Fangji (Stephaniae Tetrandrae Radix), Sumu (Pterocarpi Santalinus Lignum), Chenpi (Citri Reticulatae Pericarpium), Jiegeng (Platycodonis Radix) (each 1 qian), Zexie (Alismatis Rhizoma) (0.7 qian), Zhimu (Anemarrhenae Rhizoma, stir-fried with wine) (0.4 qian), Renshen (Ginseng Radix et Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma) (each 0.5 qian). Decoct these ingredients in water, add a small amount of wine, and take orally.
This syndrome often arises from anger, or from Wind-Heat in the Liver, Gallbladder, and Sanjiao (Triple Burner), combined with Blood deficiency. Localized swelling and pain, accompanied by chills, fever, and physical stiffness, should first be treated with Jiabian Baidu San (Modified Detoxifying Powder) to disperse exterior pathogens. If caused by anger stirring up Liver-Fire, Xiao Chaihu Tang (Minor Bupleurum Decoction) added with Lianqiao (Forsythiae Fructus), Jiegeng (Platycodonis Radix), and Jinyinhua (Lonicerae Japonicae Flos) should be administered, followed by Huoming Yin (Life-Saving Decoction) or similar formulas. If pus does not form and there is no ulceration, interior support is indicated. If pus forms with severe pain, interior support and toxin resolution are required. If pus has formed but not ruptured, acupuncture drainage is used. If the ulcer fails to close after rupture, substantial tonification of Qi and Blood is necessary.
Main Formula (Clearing Liver): Chaihu (Bupleuri Radix), Zhizi (Gardeniae Fructus, stir-fried) (each 1.5 qian), Huangqin (Scutellariae Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Renshen (Ginseng Radix et Rhizoma) (each 1 qian), Lianqiao (Forsythiae Fructus), Jiegeng (Platycodonis Radix) (each 0.8 qian), Gancao (Glycyrrhizae Radix et Rhizoma) (0.5 qian). Decoct in water and take after meals.
A carbuncle on the chest initially appears like a soybean, with unchanged skin color. If cold qi attacks the Heart, leading to mental confusion, vomiting of cold phlegm, internal sinking of toxic vapors, and abdominal distension, the prognosis is fatal. Signs such as mental restlessness, body agitation, skin feeling hot like fire, sweating, cracked lips, and thirst for cold water indicate this condition. Urgently administer Huoming Yin (Life-Saving Decoction) added with Huanglian (Coptidis Rhizoma) and Jiegeng (Platycodonis Radix), along with Dueming Dan (Life-Taking Pill), using diaphoretic or purgative methods. If malignant signs appear, Xijiao Jiedu Tang (Rhinoceros Horn Detoxifying Decoction) is used. A carbuncle on the Ying area (the high points on both sides of the chest) is called Yi Ju (Ying Carbuncle). With bluish discoloration and chills/fever, the treatment method is the same as above.
One occurring between the upper sternum and the two breasts is called Danzhong Ju (Danzhong Carbuncle). It arises in the Sea of Qi (Danzhong point), where Yin and Yang distribute, caused by disharmony of the Zang-Fu organs and emotional stagnation. It should be treated with Huoming Yin (Life-Saving Decoction) added with Zisu (Perillae Folium) and Bohe (Menthae Haplocalycis Herba) to induce sweating, combined with the selective use of Zijin Ding (Purple Gold Pellet).
A carbuncle on the Spleen region arises below the epigastrium, on both sides, resulting from excessive consumption of fried and roasted foods, and sexual activity while intoxicated or overly full. The treatment principles are largely similar with minor variations.
