【方歌】肾痈肾经不足生，京门微肿隐隐疼，少腹肋下〔月真〕
胀满，房劳形寒邪外乘。
【注】此证始发京门穴，必隐痛微肿，令人寒热往来，面白不
渴，少腹及肋下〔月真〕胀塞满。由肾虚不足之人，房
劳太过，身形受寒，邪气自外乘之。初服五积散，加细
辛；寒尽痛止，宜用桂附地黄丸调理。
京门穴又名肾募，在身侧腰中监骨下肋间。

桔梗 川芎
当归 白芍（各一钱）
麻黄 枳壳（麸炒）
桂心 干姜
厚朴（各八分） 白芷

头痛恶寒者，加速须葱头三个，盖卧汗出甚效。
【方歌】五积散苍壳陈苓，麻黄半桔归芍芎，芷朴桂心干姜草，
肾痈寒邪服成功。
又方：桂附地黄汤（见溃疡门）
【方歌】三焦痈由湿热凝，石门穴上肿隐疼，寒结治同肠痈法，
内痈俱系膜内生。
【注】此证始发石门穴，必隐疼微肿，令人寒热往来，二便秘
涩，由湿热遇寒凝结而成。治法与大、小肠痈同。凡内
痈俱系膜内成患，外皮不腐。
石门穴又名三焦募，在脐下二寸。
属性：凡人胸腹有十一募。募者，各藏府阴会之所也。《灵枢
》云：发内痈、内疽者，其本经募上肉必浮肿，募中必
时时隐痛，浮肿为痈，隐痛为疽，此即内痈、内疽之验
也。兹内痈有治法，内疽无治法何也？盖内痈、内疽，
其病原无殊，惟在根浅、根深之别耳。根浅为痈，根深
为疽。若临证用药，攻补得宜，无不收效。至募有十一
，而内痈仅九证者何也？盖胆府形如膜皮，无出无纳，
汁清气洁，不生内痈、内疽。若夫膀胱亦如膜皮，中惟
浊水，故古今书藉，并无讲及内痈内疽者，是以未敢详
载。虽然中极穴即膀胱募也，今人间有中极穴或浮肿、
或隐痛者，所见证候，竟同小肠痈，治法亦当按小肠痈
治之可也。俟后之学者留意焉。
【方歌】肾痈是由于肾经正气不足而发生的，京门穴部位出现轻微肿胀和隐隐作痛，少腹及肋下肌肉胀满，多因房事过度导致身体受寒，外邪乘虚而入所致。
【注】此证候起始于京门穴，必然表现为隐痛和轻微肿胀，使人出现寒热往来的症状，面色苍白且不口渴，少腹以及肋下肌肉胀塞满闷。这是由于肾虚不足之人，房劳太过，身形遭受寒冷，邪气从外部侵袭所致。初期服用五积散，并加入细辛；待寒气尽除、疼痛停止后，宜使用桂附地黄丸进行调理。
京门穴又名肾募穴，位于身体侧面腰部中，监骨（髂骨）下方肋骨间隙处。
方剂：五积散
组成：苍术（炒制，二钱）、陈皮、桔梗、川芎、当归、白芍（各一钱）、麻黄、枳壳（麸皮炒制）、桂心、干姜、厚朴（各八分）、白芷、半夏（炮制）、甘草（生用）、茯苓（各四分）。
煎服法：加生姜一片，水两钟，煎至八分，不拘时候服用。
加减法：若伴有头痛、恶寒者，加速葱头三个，盖被卧床令其出汗，效果显著。
【方歌】五积散由苍术、枳壳、陈皮、茯苓组成，包含麻黄、半夏、桔梗、当归、白芍、川芎，还有白芷、厚朴、桂心、干姜、甘草，治疗肾痈因寒邪所致可获成功。
又一方：桂附地黄汤（见溃疡门章节）
【方歌】三焦痈是由湿热凝结而成，在石门穴位置出现肿胀和隐隐作痛，寒凝型的治疗同肠痈的方法，内痈均系在膜原内部生成。
【注】此证候起始于石门穴，必然表现为隐痛和轻微肿胀，使人出现寒热往来、大小便便秘涩滞的症状，这是由湿热遇寒凝结而成的。治疗方法与大肠痈、小肠痈相同。凡是内痈都是在膜内形成的疾患，外皮不会溃烂腐坏。
属性：凡人的胸腹部有十一个募穴。募穴，是各脏腑之气汇聚于阴分的所在。《灵枢》记载：发生内痈、内疽的人，其本经的募穴部位肌肉必定浮肿，募穴中间必定时常隐痛，浮肿的是痈，隐痛的是疽，这就是内痈、内疽的验证。这里内痈有治疗方法，而内疽没有治疗方法，为什么呢？大概内痈和内疽，其病因本源没有区别，只在于病根深浅的不同罢了。病根浅的为痈，病根深的是疽。如果在临证用药时，攻邪与补益得当，没有不取得疗效的。至于募穴共有十一个，而内痈仅有九种证候，为什么呢？大概胆腑形状像膜皮一样，无出无纳，胆汁清且气洁，不生内痈和内疽。至于膀胱也如同膜皮，其中只有浊水，所以古今书籍，都没有讲述涉及内痈内疽的内容，因此不敢详细记载。虽然中极穴即是膀胱的募穴，如今人间有中极穴部位或浮肿、或隐痛的，所见证候，竟然同小肠痈一样，治疗方法也应当按照治疗小肠痈的方法来施治即可。等待后来的学者留意于此。
[Verse] Kidney abscess (Shen Yong) arises from deficiency of the Kidney Meridian; slight swelling and dull pain occur at Jingmen (Jingmen, GB25); distension and fullness in the lower abdomen and hypochondrium result from excessive sexual activity leading to physical coldness, allowing external pathogens to invade.
[Commentary] This condition originates at Jingmen (Jingmen, GB25), characterized by dull pain and slight swelling, causing alternating chills and fever, a pale complexion, and no thirst. There is distension and fullness in the lower abdomen and between the ribs. It is caused by individuals with Kidney deficiency who engage in excessive sexual activity, suffer from cold exposure, and allow pathogenic factors to invade from the exterior. Initially, Wuji San (Five Accumulations Powder) with added Xixin (Asari Radix et Rhizoma) should be administered. Once the cold has dissipated and pain ceases, Guifu Dihuang Wan (Cinnamon Twig and Aconite Pill for the Kidney) should be used for regulation.
Jingmen (Jingmen, GB25), also known as the Front-Mu point of the Kidney (Shen Mu), is located on the side of the body in the waist, below the iliac bone (jian gu) in the intercostal space.
Formula: Wuji San (Five Accumulations Powder)
Composition: Cangzhu (Atractylodis Rhizoma, stir-fried, 2 qian), Chenpi (Citri Reticulatae Pericarpium), Jiegeng (Platycodonis Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Danggui (Angelicae Sinensis Radix), Baishao (Paeoniae Radix Alba, 1 qian each), Mahuang (Ephedrae Herba), Zhike (Aurantii Fructus Immaturus, bran-fried), Guixin (Cinnamomi Cortex), Ganjiang (Zingiberis Rhizoma), Houpo (Magnoliae Officinalis Cortex, 8 fen each), Baizhi (Angelicae Dahuricae Radix), Banxia (Pinelliae Rhizoma, processed), Gancao (Glycyrrhizae Radix et Rhizoma, raw), Fuling (Poria, 4 fen each).
Decoction method: Add one slice of fresh ginger, two zhong of water, decoct until eight fen remains. Take at any time.
Modification: If accompanied by headache and aversion to cold, add three scallion heads. Cover the patient and induce sweating for significant effect.
[Verse] Wuji San (Five Accumulations Powder) consists of Cangzhu, Zhike, Chenpi, and Fuling, along with Mahuang, Banxia, Jiegeng, Danggui, Baishao, and Chuanxiong, plus Baizhi, Houpo, Guixin, Ganjiang, and Gancao; it achieves success in treating kidney abscess caused by cold pathogens.
Another Formula: Guifu Dihuang Tang (Cinnamon Twig and Aconite Decoction for the Kidney) (See Chapter on Ulcers).
[Verse] Sanjiao abscess (Sanjiao Yong) is formed by the coagulation of damp-heat; swelling and dull pain appear at Shimen (Shimen, CV5). Cold coagulation is treated using the same method as intestinal abscess; internal abscesses all arise within the membranes.
[Commentary] This condition originates at Shimen (Shimen, CV5), characterized by dull pain and slight swelling, causing alternating chills and fever, and constipation with difficult urination and defecation. It is formed by the coagulation of damp-heat encountering cold. The treatment method is the same as that for Large Intestine Abscess and Small Intestine Abscess. All internal abscesses are lesions formed within the membranes, without ulceration or necrosis of the external skin.
Shimen (Shimen, CV5), also known as the Front-Mu point of the Sanjiao (Sanjiao Mu), is located two cun below the umbilicus.
Attribute: There are eleven Front-Mu points in the chest and abdomen of humans. Mu points are the sites where the Qi of the Zang-Fu organs converges in the Yin aspect. The *Ling Shu* states: In cases of internal abscess (Nei Yong) and internal gangrene (Nei Ju), the flesh at the Front-Mu point of the affected meridian must swell, and there must be intermittent dull pain at the Mu point. Swelling indicates abscess, while dull pain indicates gangrene. This is the verification of internal abscess and internal gangrene. Here, internal abscess has treatment methods, but internal gangrene does not. Why? Essentially, the pathology of internal abscess and internal gangrene is identical; the difference lies only in the depth of the root. Shallow root constitutes abscess, deep root constitutes gangrene. If, during clinical practice, the use of attacking and tonifying methods is appropriate, efficacy will invariably be achieved. As for the eleven Mu points, why are there only nine types of internal abscess? The Gallbladder resembles a membrane, having no entry or exit, containing clear bile and pure Qi, thus it does not generate internal abscess or internal gangrene. The Bladder is also like a membrane, containing only turbid water; therefore, ancient and modern texts do not discuss internal abscess or internal gangrene regarding it, so I dare not record them in detail. Although Zhongji (Zhongji, CV3) is the Front-Mu point of the Bladder, nowadays when patients present with swelling or dull pain at Zhongji, the symptoms manifest identically to Small Intestine Abscess, and the treatment should follow the method for Small Intestine Abscess. Let future scholars pay attention to this.
