【方歌】胃痈表现为中脘穴处肿胀疼痛，没有咳嗽和咳痰，而是吐出脓血。其病因是饮食之毒与七情之火，治疗原则与肠痈的大法相同。
【注】此病初起时，中脘穴部位必然有隐隐作痛和轻微肿胀，伴有像疟疾一样的寒热交替症状，皮肤干枯粗糙如鳞甲，并没有咳嗽症状，但会咯吐脓血。这是由于饮食之毒和七情之火，导致热气聚集在胃部形成痈肿。如果脉象沉而数，初期服用清胃射干汤（Qingwei Shegan Tang, Clear Stomach Belamcanda Decoction）以泻下清热；如果脉象涩滞，说明有瘀血，适宜服用丹皮汤（Danpi Tang, Moutan Decoction）以泻下化瘀；如果脉象洪大且数，说明脓液已成，用赤豆薏苡仁汤（Chidou Yiyiren Tang, Red Bean and Coix Seed Decoction）以排脓；如果身体疲倦、气喘、口渴，且小便频数，这是肺气虚的表现，用补中益气汤（Buzhong Yiqi Tang, Tonify the Middle and Augment Qi Decoction）加入麦冬（Ophiopogonis Radix）、五味子（Schisandrae Fructus）来补益。其证候的生死预后及治疗方法，与大肠痈和小肠痈相同。
方剂：清胃射干汤
组成：射干（Belamcandae Rhizoma）、升麻（ Cimicifugae Rhizoma）、犀角（Rhinocerotis Cornu，现多用替代品）、麦冬（去心）（Ophiopogonis Radix）、元参（Scrophulariae Radix）、大黄（Rhei Radix et Rhizoma）、黄芩（Scutellariae Radix，各一钱）、芒硝（Natrii Sulfas）、栀子（Gardeniae Fructus）、竹叶（Phyllostachidis Folium，各五钱）。水煎服。
【方歌】清胃射干汤包含射干、升麻、犀角、麦冬全备，还有玄参、黄芩、大黄、芒硝等，加上竹叶和山栀，胃痈即可痊愈。
又一方：赤豆薏苡仁汤
组成：赤小豆（Phaseoli Semen Rubrum）、薏苡仁（Coicis Semen）、防己（Stephaniae Tetrandrae Radix）、甘草（Glycyrrhizae Radix et Rhizoma，各等分）。用水二钟，煎至八分，饭后服用。
【方歌】赤豆薏苡汤最为神奇，由甘草、防己、赤小豆、薏苡仁组成，胃痈脓成且脉象洪数时，用两钟水煎至八分服用。
又一方：丹皮汤（见大肠、小肠痈章节）
补中益气汤（见溃疡门章节）
【方歌】脾痈由湿热和瘀血凝结而成，章门穴处肿胀并伴有隐痛，出现腹胀、咽喉干燥、小便短少的症状，通过利湿化瘀和补益收功。
【注】此病起始于章门穴，必然有隐隐作痛和轻微肿胀。这是由于过食生冷食物，兼夹湿热，或者瘀血郁滞于脾经所形成。导致患者腹胀，咽喉干燥，小便短少涩痛。初期适宜使用大黄汤（Dahuang Tang, Rheum Decoction）和赤豆薏苡仁汤，将两方合用，以攻逐滞留的郁结之气。待大小便通利，腹胀完全消除后，适宜使用六君子汤（Liujunzi Tang, Six Gentlemen Decoction）扶助脾气进行调理。顺证与逆证的判断方法与胃痈相同。
[Formula Song] Gastric abscess presents with swelling and pain at the Zhongwan (CV12) acupoint, without cough or expectoration, but rather spitting of pus and blood. The etiology involves toxicity from diet and fire from emotional disturbances. The treatment principles are the same as those for intestinal abscesses.
[Annotation] In the early stage of this condition, there is invariably dull pain and slight swelling at the Zhongwan (CV12) acupoint, accompanied by chills and fever alternating like malaria, and dry, scaly skin resembling fish scales. There is no cough, but pus and blood are spat up. This arises from toxicity of diet and fire of seven emotions, causing heat to gather in the stomach and form an abscess. If the pulse is deep and rapid, initially administer Qingwei Shegan Tang (Clear Stomach Belamcanda Decoction) to purge; if the pulse is choppy, indicating blood stasis, Danpi Tang (Moutan Decoction) should be administered to purge; if the pulse is surging and rapid, indicating that pus has formed, Chidou Yiyiren Tang (Red Bean and Coix Seed Decoction) should be used to drain pus. If the body is fatigued, there is asthma, thirst, and frequent urination, this indicates deficiency of Lung Qi; Buzhong Yiqi Tang (Tonify the Middle and Augment Qi Decoction) added with Ophiopogonis Radix (Maibai) and Schisandrae Fructus (Wuweizi) should be used to tonify. The prognosis and treatment methods are the same as those for Large Intestine Abscess and Small Intestine Abscess.
Zhongwan (CV12), also known as the Front-Mu point of the Stomach, is located 4 cun above the umbilicus.
Formula: Qingwei Shegan Tang (Clear Stomach Belamcanda Decoction)
Composition: Belamcandae Rhizoma (Shé Gān), Cimicifugae Rhizoma (Shēng Má), Rhinocerotis Cornu (Xī JiǎOphiopogonis Radix (Mài Dōng, de-heartened), Scrophulariae Radix (Yuán Shēn), Rhei Radix et Rhizoma (Dà Huáng), Scutellariae Radix (Huáng Qín) [each 1 qian], Natrii Sulfas (Máng Xiāo), Gardeniae Fructus (Zhī Zǐ), Phyllostachidis Folium (Zhú Yè) [each 5 qian]. Decoct in water and take orally.
[Formula Song] Qingwei Shegan Tang contains Belamcandae Rhizoma, Cimicifugae Rhizoma, Rhinocerotis Cornu, and Ophiopogonis Radix completely; along with Scrophulariae Radix, Scutellariae Radix, Rhei Radix et Rhizoma, and Natrii Sulfas; plus Phyllostachidis Folium and Gardeniae Fructus, the gastric abscess will be cured.
Another Formula: Chidou Yiyiren Tang (Red Bean and Coix Seed Decoction)
Composition: Phaseoli Semen Rubrum (Chì Xiǎo Dòu), Coicis Semen (Yì Yǐ Rén), Stephaniae Tetrandrae Radix (Fáng Jǐ), Glycyrrhizae Radix et Rhizoma (Gān Cǎo) [equal parts]. Decoct in two zhong of water until eight fen remains, take after meals.
[Formula Song] Chidou Yiyi Tang is most miraculous, composed of Glycyrrhizae Radix et Rhizoma, Stephaniae Tetrandrae Radix, Phaseoli Semen Rubrum, and Coicis Semen. When gastric abscess pus has formed and the pulse is surging and rapid, decoct in two zhong of water until eight fen remains and take orally.
Another Formula: Danpi Tang (See Large and Small Intestine Abscess section)
Buzhong Yiqi Tang (Tonify the Middle and Augment Qi Decoction) (See Ulcer Section)
[Formula Song] Spleen abscess is caused by the coagulation of damp-heat and blood stasis, with swelling and dull pain at the Zhangmen (LR13) acupoint, accompanied by abdominal distension, dry throat, and short urine. Treatment succeeds by promoting urination to remove dampness and stasis, followed by tonification.
[Annotation] This condition begins at the Zhangmen (LR13) acupoint, invariably presenting with dull pain and slight swelling. It is caused by excessive consumption of cold and raw foods combined with damp-heat, or by blood stasis stagnating in the Spleen meridian. This leads to abdominal distension, dryness of the pharynx and throat, and scanty, astringent urination. Initially, Dahuang Tang (Rheum Decoction) and Chidou Yiyiren Tang (Red Bean and Coix Seed Decoction) should be used in combination to attack stagnation and郁结. Once bowel movements and urination are unobstructed and abdominal distension is completely resolved, Liujunzi Tang (Six Gentlemen Decoction) should be used to support the Spleen and regulate. The assessment of favorable and unfavorable courses follows the same principles as Gastric Abscess.
Zhangmen (LR13), also known as the Front-Mu point of the Spleen, is located 6 cun lateral to the umbilicus and 2 cun superior to it.
