【方歌】少腹疽生脐下边，证由七情火郁缠，高肿红疼牵背易，
漫硬陷腐水脓难。
【注】此证由七情火痈而生。每发于气海、丹田、关元三穴。
气海在脐下一寸五分，丹田在脐下二寸，关元在脐下三
寸，皆属任脉经。此三穴或一穴发肿，即为少腹疽。高
肿红活，疼痛牵背，易溃稠脓者易治；若漫肿坚硬，绵
溃腐烂，脓稀如水者难治。凡遇此证初起，急用艾灸肿
顶，七壮至三七壮，以痛痒通彻为度，宜服仙方活命饮
。气实之人，大渴便秘者，宜服内疏黄连汤通利之；老
弱之人，宜服内补十宣散，令其速溃，若溃迟恐透内膜
。外治法同痈疽肿疡、溃疡门。
方剂：仙方活命饮、内疏黄连汤（俱见肿疡门）

【方歌】腹皮痈生腹皮内，皮里膜外肿隐疼，腹痛不止脓成候，
证由膏梁郁火生。
【注】此证生于腹皮里膜外，无论左右，隐疼日久，后发痈肿
于皮外，右关脉见沈数而腹痛甚者，是其候也，由膏梁
火郁而成。初起壮实者，用双解贵金丸下之，虚弱者减
半，用之不应，再服半剂。凡下之后，腹痛不止，脓将
成也，急用托里透脓汤。溃后与痈疽溃疡门治法相同。
不可过用克伐之剂，若希图消散，过伤胃气，则肿不能
溃，溃不能敛，立见危亡矣。

【方歌】少腹疽生于肚脐下方边缘，病证由七情（喜、怒、忧、思、悲、恐、惊）导致火邪郁结缠绕而成。若肿块高起肿胀、颜色红活、疼痛牵连背部且容易溃破流脓的，属于易治之证；若肿块弥漫坚硬、凹陷腐烂、流出稀薄如水脓液的，属于难治之证。
【注】此病证是由七情内伤导致火毒痈肿而生。常发作于气海穴、丹田穴、关元穴这三个穴位。气海穴位于肚脐下一寸五分处，丹田穴位于肚脐下二寸处，关元穴位于肚脐下三寸处，这三个穴位都属于任脉经。这三个穴位中任意一个穴位发生红肿，就称为少腹疽。如果肿块高起肿胀、色泽红活，疼痛牵连背部，容易溃破且脓液稠厚的，容易治疗；如果肿块弥漫肿胀且坚硬，缓慢溃破并腐烂，脓液稀薄像水一样的，难以治疗。凡是遇到此病初起时，紧急使用艾灸灸在肿块的顶部，灸七壮至三七壮，以感到痛痒感通达透彻为限度，适宜服用仙方活命饮。体质壮实的人，出现大渴、便秘症状的，适宜服用内疏黄连汤以通利大便；年老体弱的人，适宜服用内补十宣散，使其迅速溃破，如果溃破迟缓，恐怕会穿透内膜。外治法与痈疽肿疡门、溃疡门的治法相同。

【方歌】腹皮痈生于腹部皮肤之内，皮里膜外部位肿胀且隐痛，腹痛不止是脓液形成的征候，病证由饮食肥甘厚味（膏梁）导致郁火内生而成。
【注】此病证生于腹部皮肤里面、筋膜外面，无论左侧还是右侧，长期隐痛，后来在皮肤外部发生痈肿，右关脉呈现沉数脉象且腹痛剧烈的，是其征候，由饮食肥甘厚味导致火邪郁结而成。初起时身体壮实的患者，用双解贵金丸攻下；身体虚弱的患者减半用量使用，如果使用后无效，再服用半剂。凡是攻下之后，腹痛仍然不止，说明脓液即将形成，紧急使用托里透脓汤。溃破后的治疗与痈疽溃疡门的治法相同。不可过度使用攻伐损伤正气的药物，如果贪图消散肿块，过度损伤胃气，那么肿块就不能溃破，溃破后也不能收敛愈合，立刻就会见到危亡的局面。

[Prescription Verse] Shaofu Ju (Abscess of the Lower Abdomen) arises at the edge below the umbilicus. The syndrome is caused by Fire stagnation entangled by Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright). If the swelling is high and prominent, red and vibrant, with pain radiating to the back, and it easily suppurates with thick pus, it is easy to treat. If the swelling is diffuse and hard, sunken and rotting, with thin watery pus, it is difficult to treat.
[Note] This syndrome arises from a Fire carbuncle generated by internal injury from the Seven Emotions. It frequently occurs at the Qihai (Sea of Qi), Dantian (Elixir Field), and Guanyuan (Gate of Origin) acupoints. Qihai is located 1.5 cun below the umbilicus, Dantian is 2 cun below the umbilicus, and Guanyuan is 3 cun below the umbilicus; all belong to the Ren Mai (Conception Vessel). Swelling occurring in any one of these three acupoints constitutes Shaofu Ju. If the swelling is high and prominent, red and vibrant, with pain radiating to the back, easily suppurating with thick pus, it is easy to treat. If the swelling is diffuse and hard, slowly suppurating and rotting, with thin watery pus, it is difficult to treat. Whenever this syndrome appears initially, urgently apply moxibustion to the top of the swelling, seven to twenty-one moxa cones (zhuang), until a sensation of pain or itching penetrates thoroughly. It is appropriate to administer Xianfang Huoming Yin (Immortal Life Elixir Decoction). For individuals with robust constitution presenting with intense thirst and constipation, Neishu Huanglian Tang (Internal Purging Coptis Decoction) should be administered to promote unblocking and purgation. For elderly or weak individuals, Neibu Shixuan San (Internal Tonification Ten Thousand-Expelling Powder) should be administered to facilitate rapid suppuration; if suppuration is delayed, there is a risk of penetrating the inner membrane. External treatment methods are the same as those described in the chapters on Carbuncles and Ulcers.

[Prescription Verse] Fupi Yong (Carbuncle of the Abdominal Skin) arises within the abdominal skin, swelling and dull pain in the space between the skin and fascia. Unremitting abdominal pain indicates that pus has formed. The syndrome is caused by Stagnant Fire generated from rich and greasy diet.
[Note] This syndrome arises in the space inside the abdominal skin and outside the fascia. Regardless of whether it is on the left or right, prolonged dull pain followed by the emergence of a carbuncle on the external skin characterizes it. A deep and rapid pulse at the Right Guan position accompanied by severe abdominal pain is its sign, resulting from Fire stagnation due to rich and greasy diet. In the initial stage, for robust patients, Shuangjie Guijin Wan (Double-Resolving Noble Metal Pill) should be used for purgation; for weak patients, use half the dose. If ineffective, administer another half dose. After purgation, if abdominal pain persists, it indicates that pus is about to form; urgently administer Tuoli Toung Tang (Supporting Interior and Penetrating Pus Decoction). Post-suppuration treatment is identical to that in the chapter on Carbuncle and Ulcer. Do not overuse harsh attacking agents. If one seeks resolution but excessively damages Stomach Qi, the swelling will fail to suppurate, and once suppurated, it will fail to heal, leading immediately to critical danger.
