捧心痈，生于人字骨下低陷中，肿坚色白，脉空芤无力，腰痛肤黄面浮。有因脱力中伤
，或受伤营卫失和而发；有因抑郁伤肝，肝邪乘脾，脾气不能营运，致气血留滞而发；亦有
因病后脏腑气衰，营卫不能通调而发。治法宜和营通络，调养气血，使之渐渐内消。若至成
功出脓，每易成损怯，难以痊愈。
痰生于中腕穴下，或左或右。初起结核，渐渐肿大，坚硬色白，其病因脉证，与
捧心痈相似，治法亦同。此证宜速治，若成功后，脓从呕吐出者不治。
胃腕痈者，生于中腕穴（又名胃募，在人字骨下三指，脐上四寸）。有外痈，有内痈。外
痈在皮里膜外，初起漫肿，渐渐 红成脓。此由平素醇酒浓味，湿热积聚，脾阳失运，凝滞
气血而发；或因伤寒结胸，腑气虽通，脾肺气虚，不能升降，以致湿浊混淆，留滞不散，营
卫失和而结。治当利其湿热，开提肺气，扶助脾胃，清营解毒，庶能消散。倘有脓即宜开破
，以泄其邪，后用补托收功。至于内痈，俗名 痈，生于胃中。初起中腕穴必隐痛微肿
，按之坚硬，身皮甲错（不泽也），寒热如疟。多因醇酒炙 ，七情火郁，又外感寒气隔
阳，使热浊之气填塞胃脘，胃中清气下陷，营气不从故发。右关脉必见沉细，盖胃脉见于右
关，本宜洪大，而反沉细者，是见胃气之逆也。人迎（胃经穴，在急喉两旁）脉来甚盛，以热
聚于胃口而不行，故人迎反甚耳。有此二脉，痈已成矣。其时少阴厥逆，机关不利，胸膈痞
闷，腹中疼痛连心。若脉洪数者，已有脓也，宜急排之，赤豆薏仁汤主之，大射干汤亦可。
设脉迟紧者，虽脓未成，已有瘀血也，宜急下之，牡丹皮散主之；如痰气上壅者，甘桔汤；
大便不利者，太乙膏作丸服之；小便赤涩，腹满不食者，三仁汤；体倦气喘作渴，小水频数
者，肺气虚也，补中益气汤加麦、味补之。此证若脓自口吐出，必至毒瓦斯漫延，腐烂肠胃，
脾气日衰，饮食少纳，形神憔悴，精耗气竭而毙。
捧心痈，生于胸骨剑突下方的凹陷处，肿块坚硬、颜色发白，脉象空大无力（芤脉），伴有腰痛、皮肤发黄、面部浮肿。其病因或因过度劳累导致中气受损，或因外伤导致营卫失调而引发；或因情绪抑郁损伤肝脏，肝气横逆侵犯脾土，脾气无法正常运行，致使气血停滞而引发；也有因病后脏腑元气衰弱，营卫之气不能通畅调和而引发的。治疗方法应当调和营血、疏通经络，调养气血，使肿块逐渐从内部消散。如果发展到化脓阶段，往往容易演变为虚损劳怯之证，难以痊愈。
痰痈生于中脘穴下方，位置或在左侧或右侧。初起时出现结节，逐渐肿大，质地坚硬、颜色发白，其病因、脉象和症状与捧心痈相似，治疗方法也相同。此病应当迅速治疗，如果发展到化脓阶段，脓液通过呕吐排出的则属于不治之症。
胃脘痈，生于中脘穴（又名胃募穴，位于胸骨剑突下三指宽处，脐上四寸）。分为外痈和内痈两种。外痈位于皮肤与膜之间，初起时弥漫性肿胀，逐渐变红并化脓。这是由于平时嗜食醇酒厚味，导致湿热积聚，脾阳失于运化，凝滞气血而引发；或因伤寒结胸证，虽然腑气已通，但脾肺之气虚弱，升降功能失常，导致湿浊混杂，留滞不散，营卫失调而凝结。治疗应当利湿清热，宣提肺气，扶助脾胃，清解营分热毒，才有可能消散。如果已经成脓，则应当切开排破，以泄出邪气，之后再用补益托毒的方法收功。至于内痈，俗称“胃痈”，生于胃中。初起时中脘穴部位必有隐隐作痛、轻微肿胀，按压时感觉坚硬，身体皮肤粗糙如鳞甲（缺乏光泽），寒热往来像疟疾一样。多因嗜酒及食用炙烤食物，加上七情郁结化火，又外感寒气阻隔阳气，使得热浊之气填塞胃脘，胃中清气下陷，营气运行受阻从而引发。右关脉必然呈现沉细之象，因为胃的脉象反映在右关部，本应洪大，反而沉细，这是显示胃气上逆的表现。人迎穴（胃经穴位，位于喉结两侧）脉搏跳动非常旺盛，是因为热邪聚集在胃口而不行散，所以人迎脉反而盛大。出现这两种脉象，说明痈肿已经形成。此时若出现少阴经厥逆，关节活动不利，胸膈痞闷堵塞，腹部疼痛牵连心脏。如果脉象洪数，说明已有脓液，应当紧急排脓，主用赤豆薏仁汤，大射干汤也可以使用。如果脉象迟紧，虽然脓未形成，但已有瘀血，应当紧急攻下，主用牡丹皮散；如果有痰气上壅的情况，用甘桔汤；大便不通利的，服用太乙膏制成的丸药；小便短赤涩痛、腹部胀满不能进食的，用三仁汤；身体疲倦、气喘口渴、小便频数的，属于肺气虚，用补中益气汤加麦冬、五味子来补益。此病如果脓液自行从口中吐出，必然导致毒瓦斯蔓延，腐蚀肠胃，脾气日益衰败，饮食摄入减少，形体和精神憔悴，最终因精气耗竭、元气耗尽而死亡。
Chengxin abscess (Abscess at the Xinggu point) arises in the depression below the xiphoid process. The swelling is firm and white in color, the pulse is hollow and weak (Kou pulse), accompanied by lower back pain, yellowish skin, and facial edema. Etiology may involve mid-body injury due to excessive labor, or disharmony of Ying and Wei (Nutritive and Defensive Qi) following trauma; it may also result from liver qi stagnation damaging the liver, with liver pathogenic factors invading the spleen, causing spleen qi to fail in its transporting function, leading to qi and blood stasis; or it may occur after illness when zang-fu qi declines, preventing the smooth regulation of Ying and Wei. Treatment should focus on harmonizing Ying blood and unblocking collaterals, nourishing and regulating qi and blood, allowing the swelling to gradually resolve internally. If it progresses to suppuration, it often develops into consumptive weakness (Xian Que), making recovery difficult.
Tan abscess (Phlegm Abscess) arises below the Zhongwan point (CV12), either on the left or right side. Initially presenting as a nodule that gradually enlarges, becoming hard and white. Its etiology, pulse, and symptoms are similar to Chengxin abscess, and the treatment method is also the same. This condition requires prompt treatment; if it reaches the stage of suppuration and pus is vomited out, it is considered incurable.
Weiwuan abscess (Gastric Epigastric Abscess) arises at the Zhongwan point (also known as the Front-Mu point of the Stomach, located three finger-widths below the xiphoid process, four cun above the umbilicus). It is divided into external and internal abscesses. The external abscess lies between the skin and fascia, initially presenting as diffuse swelling that gradually turns red and suppurates. This is caused by habitual consumption of rich wine and heavy flavors, leading to accumulation of damp-heat, failure of Spleen Yang to transport, and stagnation of qi and blood; or it may result from Shanghan (Cold Damage) Jie Xiong (Chest Binding), where although fu organ qi is unblocked, Spleen and Lung qi deficiency leads to failed ascending and descending functions, causing damp-turbidity to mix and stagnate, resulting in disharmony of Ying and Wei. Treatment should promote the draining of damp-heat, raise Lung qi, support the Spleen and Stomach, clear heat and detoxify the Ying level, so that resolution may be achieved. If pus has formed, incision and drainage should be performed to expel pathogens, followed by tonification and expulsion therapies to conclude treatment. As for the internal abscess, commonly called "Wei Yong" (Stomach Abscess), it arises within the stomach. Initially, there is dull pain and slight swelling at the Zhongwan point, hardness upon palpation, rough skin texture (lack of luster), and alternating chills and fever resembling malaria. Etiology often involves alcohol consumption, roasted foods, emotional stagnation transforming into fire, combined with external cold obstructing yang, causing hot turbid qi to fill the epigastrium, sinking of clear stomach qi, and obstruction of Ying qi flow. The Right Guan pulse will necessarily appear deep and fine; since the Stomach pulse manifests at the Right Guan position, which should normally be洪大 (Huge and Large), a deep and fine pulse indicates rebellious Stomach qi. The Renying point (ST9, located on both sides of the carotid artery) pulse will be very vigorous because heat gathers at the stomach opening but fails to disperse. With these two pulses, the abscess is confirmed. At this time, Shaoyin jue-ni (Jueyin/Shao Yin reversal/cold extremities) may occur, joint movement becomes difficult, chest and diaphragm feel stifled and blocked, and abdominal pain radiates to the heart. If the pulse is洪数 (Huge and Rapid), pus has formed, and urgent drainage is required; Chidou Yiren Tang (Red Bean and Coix Seed Decoction) is the primary formula, and Daye Gan Tang (Large Belamcanda Decoction) may also be used. If the pulse is迟紧 (Slow and Tight), although pus has not yet formed, blood stasis exists, requiring urgent purgation; Mudan Pi San (Moutan Bark Powder) is the primary formula. For phlegm-qi rebellion upward, Ganjie Tang (Licorice and Platycodon Decoction) is used; for constipation, Taiyi Gao pills are taken; for dark, scanty urine, abdominal fullness, and anorexia, Sanren Tang (Three Seeds Decoction) is used; for fatigue, asthma, thirst, and frequent urination, indicating Lung qi deficiency, Buzhong Yiqi Tang (Middle-Boosting Qi-Supplementing Decoction) with Maidong (Ophiopogon Tuber) and Wuweizi (Schisandra Fruit) is used for supplementation. If pus is vomited spontaneously from the mouth in this condition, toxic vapors will spread, rotting the intestines and stomach, spleen qi will decline daily, food intake will decrease, physical and mental exhaustion will set in, and death will ensue from depletion of essence and exhaustion of qi.
