除湿二陈汤，用于治疗臀痈、上马痈、下马痈等病症。
陈皮、半夏、茯苓、秦艽、薏苡仁、麦冬、甘草（各等分）。
用生姜一片，灯心草二十根，加水煎煮，饭后服用。
内托羌活汤，用于尻部及臀部生痈，局部坚硬、肿胀、疼痛者。
黄芪（一钱五分）、黄柏（酒炒）、羌活（各三钱）、防风、当归尾、藁本、连翘、苍术、陈皮、炙甘草（各一钱）、肉桂（三分）。
用水一盏，黄酒半盏，煎至八分满，饭前服用。
绀珠丹、贵金丸、绀珠膏、卫生散、托里消毒散、六君子汤、六味地黄丸（均见于本书首卷）。
上马痈，生于臀部，靠近肛门右侧。
下马痈，生于臀部，靠近肛门左侧。
上述两种病症的治疗方法同臀痈相同。
风疳生于臀部和大腿，俗称坐板疮，形状像疥癣，破溃后流出黄色液体，先痒后痛，由风寒邪气客居肛门所致。适宜使用香白散等药物外敷，使毒液排尽，即可结痂痊愈。
香白散：枯白矾、轻粉（各二钱），樟脑（一钱）。
共研为细末。若患处湿润则干撒药粉；若患处干燥则用生桐油调匀后外敷。
另一种用法：用丝瓜皮焙干研末，烧酒调敷；或用大蒜瓣烧至存性，研末撒敷；或用芫花根煎汤清洗患处。
悬痈，生于会阴穴，位于阴囊后方，肛门前方。初起时如松子大小，随后增大如莲子，数日后发作，红肿热痛，最终大如桃李。
涌泉疽，生于尻骨前方。医书记载：肿胀发于足太阴经，形状像伏着的老鼠，十日后可针刺。排出白色脓液者为顺证，青色脓液者为险证，赤黑色脓液者为逆证，若不针刺排脓则致死。
穿裆发，生于穷骨穴，即阴器底部。患处色红肿胀，疼痛牵连阴器、腰背及肛门。可灸三阴交穴三七壮。
跨马痈，生于两腿之间，靠近阴毛分布处。
以上病症，都生于前阴之后、后阴之前，因其形态不同而得名各异。这些病症属于任脉的别络，是夹督脉波脉交汇之处，由足三阴经亏损，多兼有情志欲望不得满足所致。轻则形成瘘管，重则导致死亡。因此出现麻木、黑陷、泄泻、呕吐呃逆、疲倦等症状，或病程迁延日久导致肛门内部脏腑溃烂的，都属于不治之症。古语说：阳气亢盛者适宜服用坎离丸，取其苦寒之性能泻水中之火，使阳气衰退则阴精自生；阳气衰弱者适宜服用六味地黄丸，取其酸温之性能生火中之水，使阳气旺盛则阴精自生。然而此类病症属阴精衰弱的占十之八九，阳气亢盛的仅占百中一二。
初起时若有肿痛、小便赤涩症状，先服用制甘草一二剂，并配合蒜灸治疗。随后服用龙胆泻肝汤。若已成脓且无法通过内服消散者，使用托里消毒散加穿山甲、皂角刺。若自行破溃或脓液胀痛者，进行针刺引流。早晨服用六味地黄丸，中午服用十全大补汤，加牡丹皮、泽泻，或者再加附子。若久病形成瘘管者，宜用国老膏化开汤剂吞服蜡矾丸，间歇使用豆豉饼灸法。日久则使用大附子饼灸法。如果出现傍晚发热、烦躁口渴、气喘、身体疲倦、食欲减退、大便溏薄、小便频数等症状，这是脾虚的表现。适宜服用补中益气汤加茯苓、半夏。待饮食增进，诸症减轻后，再加麦冬、五味子，疾病自然痊愈。医经云：此为阴虚兼脾虚。脾属阴土而主生血，如果误用知母、黄柏等苦寒药物，再次损伤脾肺，就是断绝了气血生化之源。

Ingredients: Chenpi (Aged Tangerine Peel), Banxia (Pinellia Rhizome), Fuling (Poria), Qinjiao (Gentiana Macrophylla Root), Yiyiren (Coix Seed), Maidong (Ophiopogon Tuber), Gancao (Licorice Root). Dosage: Equal parts.
Preparation: Use one slice of Shengjiang (Fresh Ginger) and twenty stalks of Dengxincao (Juncus Medulla). Decoct in water. Take after meals.
Neituo Qianghuo Tang (Interior-Supporting Notopterygium Decoction) is indicated for carbuncles arising in the sacral and gluteal regions, presenting with hardness, swelling, and pain.
Ingredients: Huangqi (Astragalus Root, 1.5 qian), Huangbai (Phellodendron Bark, wine-fried), Qianghuo (Notopterygium Rhizome, each 3 qian), Fangfeng (Saposhnikovia Root), Guiwei (Angelica Sinensis Tail), Bencao (Ligusticum Chuanxiong Rhizome), Lianqiao (Forsythia Fruit), Cangzhu (Atractylodes Rhizome), Chenpi (Aged Tangerine Peel), Zhigancao (Honey-fried Licorice Root, each 1 qian), Rougui (Cinnamon Bark, 0.3 qian).

Ganzhou Dan, Guijin Wan, Ganzhou Gao, Weisheng San, Tuoli Xiaodu San, Liujunzi Tang, Liuwei Dihuang Wan (all described in the first volume of this book).
Shangma Abscess arises on the buttock, near the right side of the anus.
Xiaoma Abscess arises on the buttock, near the left side of the anus.
The treatment for these two conditions is the same as that for Buttock Carbuncle.
Fenggan arises on the buttocks and thighs, commonly known as "Sitting Board Sore." It resembles scabies or tinea, breaks open to discharge yellow fluid, and presents with itching preceding pain. It is caused by wind-cold pathogenic factors lodging in the anal region. It is appropriate to apply Xiangbai San or similar medicaments externally to allow the toxic fluid to drain completely, leading to scabbing and healing.
Xiangbai San: Kubai Fan (Calcined Alum), Qingfen (Calomel, each 2 qian), Zhangnao (Borneol, 1 qian).
Grind all into powder. If the lesion is moist, sprinkle the dry powder; if dry, mix with raw Tung Oil for topical application.
Alternative methods: Roast Loofah Skin to dryness, grind into powder, and apply mixed with Sha Jiu (Baijiu); or roast Garlic Clove until carbonized (preserving its nature), grind into powder, and sprinkle; or decoct Yuanhua Root in water to wash the affected area.
Xuanyong arises at the Huiyin Acupoint, located posterior to the scrotum and anterior to the anus. Initially, it is like a pine cone; subsequently, it enlarges to the size of a lotus seed. After several days, it erupts with redness, heat, swelling, and pain, eventually becoming as large as a plum or peach.
Yongquan Ju arises anterior to the sacrum. Medical texts state: Swelling manifests along the Taiyin Meridian, resembling a crouching mouse. It may be punctured after ten days. Discharge of white pus indicates a favorable prognosis; green pus indicates danger; red-black pus indicates an unfavorable prognosis. Failure to puncture leads to death.
Chuandang Fa arises at the Qiongu Acupoint, which is the base of the genitalia. The area is red and swollen, with pain radiating to the genitals, lower back, and anus. Moxibustion should be applied to Sanyinjiao Acupoint for thirty-seven moxa cones.
Kuma Abscess arises between the legs, near the pubic hair line.
Note: All the above conditions arise posterior to the anterior yin (genitals) and anterior to the posterior yin (anus). They are named differently due to their distinct morphologies. These conditions belong to the collateral branches of the Ren Mai (Conception Vessel) and are located at the convergence of the Du Mai (Governor Vessel) and Bo Mai vessels. They result from deficiency of the Three Yin Meridians of the Foot, often compounded by unfulfilled sexual desires. Mild cases may develop into fistulas; severe cases may lead to death. Therefore, symptoms such as numbness, black depression, diarrhea, vomiting, hiccups, and fatigue, or prolonged progression leading to internal organ ulceration via the anal canal, are considered incurable. Ancient texts state: For those with hyperactive Yang Qi, Kanli Wan is suitable, utilizing its bitter-cold property to drain fire within water, thereby reducing Yang Qi so that Yin naturally generates. For those with deficient Yang Qi, Liuwei Dihuang Wan is suitable, utilizing its sour-warm property to generate water within fire, thereby strengthening Yang Qi so that Yin naturally generates. However, nine out of ten cases of this condition involve Yin Essence deficiency, while only one in a hundred involves Yang Qi hyperactivity.
In the initial stage, if there is swelling, pain, and dark, scanty urination, first administer Zhi Gancao (Processed Licorice Root) for one to two doses, combined with Suan Jiu (Garlic Moxibustion). Subsequently, administer Longdan Xiegan Tang (Gentian Liver-Draining Decoction). If the abscess has matured and cannot be resolved internally, use Tuoli Xiaodu San (Interior-Supporting Toxin-Resolving Decoction) added with Chuanshanjia (Pangolin Scale) and Zaojiaoci (Gleditsia Spine). If it ruptures spontaneously or causes distending pain due to pus, perform needle drainage. In the morning, administer Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia); at noon, administer Shiquan Dabu Tang (Ten-Ingredient Great Tonifying Decoction) added with Mudanpi (Tree Peony Bark), Zexie (Alisma Rhizome), or additionally Fuzi (Aconite Root). If it becomes a chronic fistula, dissolve Guolao Gao (Honey Confection) in decoction and swallow with Lafan Wan (Beeswax-Alum Pill). Intermittently apply Douchi Bing Jiu (Fermented Soybean Cake Moxibustion). For long-standing cases, apply Da Fuzi Bing Jiu (Large Aconite Cake Moxibustion). If evening fever, irritability, thirst, panting, body fatigue, poor appetite, loose stools, and frequent urination occur, this indicates Spleen Deficiency. It is appropriate to administer Buzhong Yiqi Tang (Middle-Warming Qi-Boosting Decoction) added with Fuling (Poria) and Banxia (Pinellia Rhizome). Once appetite improves and other symptoms subside, add Maidong (Ophiopogon Tuber) and Wuweizi (Schisandra Berry) for natural recovery. The Classics state: This is Yin Deficiency combined with Spleen Deficiency. The Spleen is Yin Earth and governs blood generation. If one mistakenly uses bitter-cold agents such as Zimu (Anemarrhena Rhizome) and Huangbai (Phellodendron Bark), further damaging the Spleen and Lung, it severs the source of Qi and Blood production.
