脐乃肾经部位，湿热积遏肾经，故脐中作烂也。亦由酒醉入房所致。

脐中出血，乃肾火外越也。以六味地黄加骨碎补一钱饮之即愈。六味汤滋其水
则火自息焰矣！骨碎补功能止窍补骨中之漏，故加入相宜耳。
王肯堂曰∶脐上疽，脐上寸许，此名冲疽，又名中发疽，一名壅肾疽。由心火炽盛，流入肾经
所致。肿高脓稠色赤可治；

久不敛者死。凡此危证，只是虚耳，如能大补不死也。（《准绳》）

补者顺；若平塌紫黑，脓水清稀，七恶证见者逆。

肚脐是足少阴肾经所主的部位，若湿热之邪积聚郁遏于肾经，就会导致肚脐溃烂。这也常因酒后行房事所致。
龙骨散（出自《锦囊》）
龙骨、黄连（各一钱）、白矾、轻粉（各五分）
将药物研成细末，直接干撒在肚脐中。
肚脐生疮：用东面墙壁上的土敷贴。
肚脐出血，这是肾火向外越逸的表现。服用加入一钱骨碎补的六味地黄丸汤剂即可痊愈。六味地黄汤能滋养肾水，则虚火自然平息。骨碎补具有填补耳窍和骨骼中漏损的功能，所以加入此方十分适宜。
王肯堂说：生于肚脐上方约一寸处的疽，名叫冲疽，又名叫中发疽，还有一个名字叫壅肾疽。这是由于心火炽盛，流注到肾经所导致的。如果肿起高突、脓液稠厚且颜色红赤，是可以治疗的；如果肿势平塌、颜色黑紫、腹部膨胀恶心、脓水清稀、内部肾脏疼痛、极度口渴且腹泻无度、胡言乱语且目光直视的，属于死证。溃疡日久不能收敛的，也属死证。凡是这些危重证候，都是因为正气虚弱，如果能进行大补治疗，就不会死亡。（出自《准绳》）
《医宗金鉴·心法要诀》说：冲疽生于任脉脐上二寸处（即下脘穴），表现为色赤黄肿，通常在二十一天左右溃破，若脓液稠厚且身体能承受补益药性的为顺证；如果肿势平塌、颜色紫黑、脓水清稀、出现七恶证的为逆证。
王肯堂说：脐痈生于肚脐正中，是由于心经积热流注到大肠和小肠两条经脉所导致的。肚脐是任脉的神阙穴，禁止针刺，应尽早使其消散，以免化脓成为上策。（出自《准绳》）
窦汉卿说：脐痈生于肚脐之中，是因为食用生冷油腻食物，导致邪气积聚在气海之间，聚结而成痈。如果不迅速治疗就会向内溃烂，从脐内流出脓液，四周坚硬，或者流出紫红色血水的，就难以治疗，如果没有这些症状则预后良好。适宜多服用腊矾丸。
胡公弼说：脐痈是心经受邪传变至小肠经，毒气发作于肚脐，严重的甚至从肚脐中排出粪便。（出自《青囊》）
《医宗金鉴·心法要诀》说：脐痈禁止针刺，若肿势大如瓜，高突如铃，没有红肿发热现象，适宜隔着蒜片灸治。溃破后流出稠脓的为吉兆；时常流出污水且气味臭秽的为逆兆。
The navel is the area governed by the Kidney Meridian. When damp-heat accumulates and stagnates in the Kidney Meridian, it causes ulceration of the navel. This condition may also be caused by sexual intercourse after excessive alcohol consumption.
Longgu San (Dragon Bone Powder) [from *Jinnang*]
Longgu (Fossilized Bones), Huanglian (Coptidis Rhizoma) (each 1 qian), Baifan (Alumen), Qingfen (Calomelas) (each 5 fen).
Grind into powder and apply dry to the navel.
For sores in the navel: Apply soil from the east-facing wall.
Bleeding from the navel indicates that Kidney Fire is escaping outward. It can be cured by drinking a decoction of Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) with one qian of Gusuibu (Drynariae Rhizoma). Liuwei Tang nourishes the Water (Kidney Yin), thereby extinguishing the Fire naturally. Gusuibu has the function of stopping leakage from orifices and replenishing bone marrow, making it suitable for addition to this formula.
Wang Kentang stated: An ju (carbuncle) located about one cun above the navel is named Chong Ju (Chong Carbuncle), also known as Zhongfa Ju (Middle-Erupting Carbuncle) or Yong Shen Ju (Obstructing-Kidney Carbuncle). It is caused by blazing Heart Fire flowing into the Kidney Meridian. If the swelling is high and protruding, with thick pus that is red in color, it is treatable; if the swelling is flat and collapsed, black in color, accompanied by abdominal distension, nausea, thin and watery pus, internal Kidney pain, extreme thirst, uncontrolled diarrhea, delirious speech, and fixed gaze, it is fatal. If the ulcer fails to heal after a long time, it is also fatal. All these critical conditions are due to deficiency; if robust tonification is applied, death can be avoided. (*Zhunsheng*)
*Xinfa* states: Chong Ju arises at two cun above the navel on the Ren Mai (Conception Vessel) (at the Xiaowan acupoint). It presents with red-yellow swelling. It typically suppurates after twenty-one days. If the pus is thick and the patient can tolerate tonifying herbs, it is a favorable sign (Shun); if the swelling is flat and collapsed, purple-black in color, with thin watery pus, and signs of the Seven Adversities appear, it is an unfavorable sign (Ni).
Wang Kentang stated: Qi Yong (Navel Abscess) occurs at the center of the navel, caused by accumulated heat in the Heart Meridian flowing into the Large Intestine and Small Intestine meridians. The navel is the Shenque acupoint of the Ren Mai, which is contraindicated for acupuncture. Early resolution should be sought to avoid suppuration, which is the superior approach. (*Zhunsheng*)
Dou Hanqing stated: Qi Yong arises in the navel due to the accumulation of cold and greasy foods in the Qihai area, forming a knot that becomes an abscess. If not treated promptly, it will rupture internally, discharging pus from within the navel, with surrounding hardness, or discharging purplish bloody fluid; such cases are difficult to treat. Without these symptoms, the prognosis is good. It is advisable to take La Fan Wan (Waxed Alum Pill) frequently.
Hu Gongbi stated: Qi Yong is a manifestation of the Heart Meridian transmitting pathogenic factors to the Small Intestine Meridian, with toxicity erupting at the navel. In severe cases, feces may even discharge from the navel. (*Qingnang*)
*Xinfa* states: Qi Yong is contraindicated for acupuncture. If the swelling is large like a melon and high-protruding like a bell, without redness or heat, moxibustion with garlic slices is appropriate. Discharge of thick pus after ulceration is auspicious; frequent discharge of foul-smelling turbid water is inauspicious.
