【纲】仲景曰。伤寒四五日。腹中痛。若转气下趋少腹者。此欲自利也。
【目】柯琴曰。此自利之兆也。四五日。是太阴发病之期。
【总纲】张仲景说：太阴病的主要表现是腹部胀满，呕吐，饮食难以下咽，腹泻逐渐加重，时常出现腹部自发性疼痛。如果误用泻下法，必然导致心窝部痞结坚硬。
【细目】朱肱说：原本患有太阳病，医生反而使用了泻下法，因此出现腹部胀满、时发疼痛的症状。这说明既有表证，又有里证。张仲景因此使用桂枝加芍药汤治疗；病情严重的，加大黄。桂枝加芍药汤，其实就是小建中汤的变方。张仲景说：太阴病患者脉象虚弱且自利，如果应当使用大黄、芍药的，应该减少剂量。这是因为患者胃气虚弱，阳气容易波动的缘故。对于下利的患者，先煎煮芍药十余沸。
腹痛有两种症状：有热痛，有冷痛。尺脉弦，伴有肠鸣、泄泻和疼痛的，属于冷痛。用小建中汤治疗；如果不愈，改用大柴胡汤（注：原文此处可能有误或特指某版本，通常小建中不瘥可考虑其他温中或疏肝理气方，但依原文翻译为小柴胡汤，后文吴绶条提到小柴胡去芩加芍，此处暂按原文“小柴胡汤”译出，或结合上下文理解为调和之剂，严格依原文译为小柴胡汤）。阴症腹痛，用四逆散或四逆加芍药汤。腹痛且小便不利的，用真武汤。关脉实，腹部胀满、大便秘结，按压时疼痛的，属于热痛。用桂枝加大黄黄连汤、大承气汤。
太阴病大体上可以用温法治疗。然而必须有积滞，才可以采用下法。什么叫积滞证？太阴病的腹部胀满、时发疼痛，胸膈不畅，满闷闭塞，嘴唇发青，手脚冰冷，脉象沉细，精神萎靡，或者腹痛，这名叫太阴病。近代人都不认识阴症，才见到胸膈不畅，就投用热药，这不是正确的治法。大抵阴症，是由冷物损伤脾胃，阴经受邪所致。主要症状是胸膈胀闷，面色及嘴唇都没有光泽，手脚冰冷，脉象沉细，精神萎靡。也不是因为嗜欲过度，只是内伤冷物，或者损伤了胃气，于是形成阴症。如果再投用巴豆之类的猛药，胸膈会更加不畅，或者呕吐并腹泻，经过一两天，就会导致不治。这是因为不知道寒邪中于太阴的缘故。
问：万一饮食不节制，寒邪侵入阴经，用什么方法治疗？答：用理中汤加青皮、陈皮，服用一两剂，胸膈就会舒畅。也可以用枳实理中丸、五积散。太阴脾经，主管胸膈满闷。《甲乙经》说：贼风虚邪等外邪，阳经受之；饮食不节，起居不时等内因，阴经受之。阳经受邪则传入腑，表现为身体发热，不时气喘呼叫；阴经受邪则传入脏，表现为胸腹满闷闭塞，下部发生完谷不化的泄泻，日久则发展为肠澼（痢疾）。
腹胀满，是阴阳不和的表现。桔梗半夏汤效果最好。张仲景论述太阳病发汗后出现腹胀满的，用厚朴生姜半夏甘草人参汤；攻下后出现心烦、腹部胀满、卧起不安的，用栀子厚朴汤；催吐后出现腹胀满的，用调胃承气汤。
成无己说：腹满，俗称肚胀。华佗说：伤寒第一天在皮，第二天在肤，第三天在肌，第四天在胸，第五天在腹，第六天入胃。入胃，就是入腑的意思。此时病在腹，还没有完全入里。虽然腹满是里证，但也有浅深之别。经文说：表证已解而内部没有消除，如果不是大满，还会产生寒热，那么病就不会解除。这是说病邪未完全入腑。如果是大满大实，坚硬且有燥屎，自然可以使用下法，即使过了四五日也不妨碍，这叫邪气已入腑。伤寒邪气进入腹部，说明里证已深，所以腹满才可以攻下。如经文所说：如果热势不潮盛，不可与承气汤。如果腹部大满不通，可以与小承气汤。原本患太阳病，医生反而误下，因而出现腹部胀满、时发疼痛的，属于太阴病，用桂枝加芍药汤；大实痛的，用桂枝加大黄汤。少阴病腹胀不大便的，急下之。诸如此类的，都是里证。虽然说腹满痛为实证，但是腹满持续不减的为实，可以攻下；腹满时减的为虚，不可攻下，应用温药调和。因为虚气停留也会引起胀满，只是比起实证，不至于坚硬疼痛。
王肯堂说：结胸从心下起始直到小腹硬满而痛，与腹满类似。但是结胸按压时疼痛剧烈，手不能靠近；腹满痛则是举按都常痛，手靠近并不特别痛苦。痞证也从心下起始直到小腹，也与腹满类似。但是痞证有时只停留在心下，腹满只在腹部中间。邪气入里与正气搏结，就会腹痛，所以疼痛的情况有所不同。腹痛属里证。太阳病腹部不痛，少阳病也是胸胁痛而无腹痛。如果阳明病腹满急迫而痛，这是里实证，适宜攻下，用大柴胡汤、小承气汤。三阴病下利清谷而又腹痛，是因为里寒。这里总论太阳经中的阴证，用四逆汤、附子理中汤。阳气传入太阴经导致腹满而痛，其症状有两种：有实痛，有虚痛。肠鸣泄泻而痛的，是虚痛。这里独论太阴经中的阳证，用小建中汤，即桂枝加芍药汤，只是桂枝用量有浓薄之分。如果不愈，用小柴胡汤去黄芩，加芍药如原数。腹满便秘，按压疼痛的，是实痛。用桂枝汤加大黄一钱。这种虚痛实痛，是以阳邪逐渐消退为虚，阳气盛大为实。
吴绶说：凡是腹痛可以按揉的，是内虚；不可以按揉的，是内实。海藏说中脘痛，属于脾土。脉沉迟、内寒的，用理中汤、附子理中丸。阳脉涩、阴脉弦的，用小建中汤。如果小腹痛属于厥阴经分，用当归四逆汤加吴茱萸。厥逆者同此法。如果是大实腹满痛，绕脐刺痛，不大便，脉实，用大承气汤。凡是潮热、不大便，从心下至少腹硬满而痛，手不可靠近的，用大陷胸汤。如果脉弦腹痛，无热无寒，用芍药甘草汤。脉弦口苦，发热腹痛，用小柴胡汤去人参加炒白芍。如果寒热交作腹痛，加肉桂、白芍。如果寒多而痛，去黄芩加肉桂、白芍。凡是少阴病发热、手足冷、腹痛，用四逆散加附子、肉桂、吴茱萸、白芍。凡是发热、脉洪弦、腹痛，用芍药黄芩汤。凡是蓄血，也令人腹痛，手不可靠近。腹痛想吐利且烦躁的，多有痧毒。世俗刮刺委中穴。
柯琴说：太阴之上，湿气主令。腹痛吐利，是从湿化生的。所以人伤于湿，脾先受之。然而寒湿侵入阴经，不能动及五脏，则还入于胃腑。太阴经布散于胃中，又发于胃。胃中寒湿，所以食物不能容纳而吐利。太阴脉从足入腹，寒气时时上逆，所以腹部时常自发疼痛。治法应当温中散寒。如果误用下法，胃口受寒，所以心窝下部痞结坚硬。
【总纲】张仲景说：伤寒脉浮而缓，手脚自温的，病系在太阴。太阴病应当发身黄，如果小便自利的，就不能发黄。到了七八天，虽然突然烦扰，一天腹泻十几次，必定会自行停止，因为脾家实，腐秽之物应当排出的缘故。
【细目】许叔微说：《难经》说：痛为实证。脾家实，知道其实必痛。大抵痛证适宜用下法。
成无己说：腹满，是太阴病。阳热作为邪气的，则腹满而咽干；阴寒作为邪气的，则腹满而吐，饮食不下，腹泻逐渐加重，时常腹部自发疼痛。太阴，是脾土，治理中央，所以专门主管腹满的症状。另外，发汗、催吐、攻下后形成的腹满，都是邪气乘虚内侵所致，但所主治的方法又各不相同。经文说：发汗后腹胀满的，用厚朴生姜甘草半夏人参汤。伤寒催吐后腹胀满的，用调胃承气汤。伤寒攻下后心烦、腹胀满、卧起不安的，用栀子厚朴汤。这三种情况，有的应当温，有的应当下，有的应当吐，为什么呢？因为邪气不同。况且发汗则表邪虽去，但汗多亡阳，导致胃气虚，不能敷布，诸气壅滞而为胀满的，这是应当温散。催吐后邪气在胸中的，能去则安，如果不能去，导致胸中之邪下传入胃而成实，遂生胀满的，这是又应当攻下。妄用攻下后，邪气在表，未经入腑，遂自表乘虚而入，郁于胸中，导致虚烦，气上下不得通，腹部为之胀满的，这是又应当吐。医者要识别邪气从何而来，知道它的由来，观察邪气所在，知道虚实，这样汗、吐、下之法不效的情况就可以避免了。
[General Principle] Zhang Zhongjing said: The main manifestations of Taiyin disease are abdominal fullness, vomiting, difficulty in swallowing food, worsening diarrhea, and spontaneous abdominal pain occurring from time to time. If purgatives are mistakenly used, it will inevitably lead to hardness and obstruction below the heart (epigastric region).
[Detailed Commentary] Zhu Gong said: Originally suffering from a Taiyang disease, if the physician erroneously uses purgation, abdominal fullness and intermittent pain result. This indicates that both exterior and interior syndromes are present. Therefore, Zhang Zhongjing uses Guizhi Jia Shaoyao Tang (Cinnamon Twig Decoction with Added Paeonia) for treatment; in severe cases, Rhubarb is added. Guizhi Jia Shaoyao Tang is essentially a variation of Xiaojianzhong Tang (Minor Construct the Middle Decoction). Zhang Zhongjing stated: In Taiyin patients with weak pulses and spontaneous diarrhea, if Da Huang (Rhubarb) and Bai Shao (White Peony Root) should be used, their dosages should be reduced. This is because the patient's stomach qi is deficient, and yang qi is prone to disturbance. For patients with diarrhea, boil Bai Shao (White Peony Root) for more than ten boils first.
There are two types of abdominal pain symptoms: heat pain and cold pain. A wiry radial pulse accompanied by borborygmus, diarrhea, and pain indicates cold pain. Treat with Xiaojianzhong Tang (Minor Construct the Middle Decoction); if ineffective, switch to Xiao Chaihu Tang (Minor Bupleurum Decoction). For yin syndrome abdominal pain, use Sini San (Bupleurum Powder for Reversing Cold) or Sini Jia Shaoyao Tang (Bupleurum Powder for Reversing Cold with Added Paeonia). For abdominal pain with difficulty in urination, use Zhenwu Tang (True Warrior Decoction). A solid guan pulse, abdominal fullness, constipation, and tenderness upon palpation indicate heat pain. Treat with Guizhi Jia Dahuang Huanglian Tang (Cinnamon Twig Decoction with Added Rhubarb and Coptis) or Dachengqi Tang (Major Order the Qi Decoction).
Taiyin diseases are generally treated with warming methods. However, purgation can only be used if there is accumulation. What constitutes an accumulation syndrome? Abdominal fullness and intermittent pain characteristic of Taiyin, chest and diaphragm discomfort, stuffiness and obstruction, cyanosis of the lips, cold hands and feet, deep and fine pulse, and listlessness, or abdominal pain, are named Taiyin disease. Modern physicians often fail to recognize yin syndromes; upon seeing chest discomfort, they immediately administer hot medicines, which is incorrect treatment. Generally, yin syndromes arise from cold substances damaging the spleen and stomach, affecting the yin meridians. The primary symptoms include chest and diaphragm distension, lackluster complexion and lips, cold extremities, deep and fine pulse, and listlessness. This is not due to excessive desires but rather internal injury from cold substances or damage to stomach qi, resulting in a yin syndrome. Administering harsh drugs like Croton Seed (Badou) again will worsen the chest discomfort, potentially causing vomiting and diarrhea. After one or two days, this may lead to death, due to ignorance of cold pathogenic factors attacking the Taiyin.
Q: If dietary irregularity causes cold pathogens to invade the yin meridians, what is the treatment? A: Use Lizhong Tang (Middle Regulating Decoction) with Qingpi (Aged Tangerine Peel) and Chenpi (Tangerine Peel), taken for one or two doses, to relieve chest discomfort. Zhishi Lizhong Wan (Immature Bitter Orange Pill for Middle Regulating) or Wuji San (Five Accumulations Powder) can also be used. The Taiyin spleen meridian governs chest fullness. The *Jiayi Jing* states: External pathogens like treacherous winds and vacuous evils affect the yang meridians; irregular diet and lifestyle affect the yin meridians. Yang meridian invasion enters the fu organs, causing fever and occasional panting/calling out. Yin meridian invasion enters the zang organs, causing chest/abdominal fullness and obstruction, and lower body loose stools with undigested food (Sunxie). Over time, this develops into Chang Pi (intestinal dysentery).
Abdominal distension is a disharmony of yin and yang. Jiegeng Banxia Tang (Platycodon and Pinellia Decoction) is most effective. Zhang Zhongjing discussed abdominal fullness after sweating in Taiyang disease, prescribing Houpo Shengjiang Banxia Gancao Renshen Tang (Magnolia Bark, Fresh Ginger, Pinellia, Licorice, and Ginseng Decoction); abdominal fullness and restlessness after purgation, prescribing Zhizi Houpo Tang (Gardenia and Magnolia Bark Decoction); and abdominal fullness after emesis, prescribing Tiaowei Chengqi Tang (Regulate the Stomach and Order the Qi Decoction).
Cheng Wuji said: Abdominal fullness is commonly called belly bloating. Hua Tuo stated: On the first day of Shanghan, the pathogen is in the skin; on the second day, in the flesh; on the third day, in the muscles; on the fourth day, in the chest; on the fifth day, in the abdomen; on the sixth day, it enters the stomach. Entering the stomach means entering the fu organs. At this stage, being in the abdomen does not mean fully entering the interior. Although abdominal fullness is an interior syndrome, there are degrees of depth. The classic states: If the exterior is resolved but internal stagnation remains, and it is not a major fullness, chills and fever may persist, indicating the disease is not cured. This implies the pathogen has not fully entered the fu organs. If there is major fullness and excess, with hard dry feces, purgation is appropriate even after four or five days, indicating the pathogen has entered the fu organs. When Shanghan pathogens enter the abdomen, the interior syndrome is deep, so abdominal fullness warrants purgation. As the classic says: If the fever is not tidal, do not give Chengqi formulas. If the abdomen is largely full and obstructed, give Xiao Chengqi Tang (Minor Order the Qi Decoction). Originally having Taiyang disease, erroneous purgation leading to abdominal fullness and intermittent pain belongs to Taiyin, treated with Guizhi Jia Shaoyao Tang. For severe excess pain, use Guizhi Jia Dahuang Tang (Cinnamon Twig Decoction with Added Rhubarb). For Shaoyin syndrome with abdominal fullness and constipation, urgent purgation is required. These are all interior syndromes. Although abdominal fullness and pain are often excess, persistent fullness without relief indicates excess and warrants purgation. Intermittent fullness that relieves itself indicates deficiency and contraindicates purgation; instead, use warm medicines to harmonize. Deficient qi retention also causes bloating, but unlike excess, it is not hard or severely painful.
Wang Kentang said: Jie Xiong (Chest Binding) starts from below the heart down to the small abdomen with hardness, fullness, and pain, resembling abdominal fullness. However, Jie Xiong is extremely tender to touch, preventing proximity; abdominal fullness pain is tender upon lifting and pressing, but not intolerable to proximity. Pi (Stagnation) also starts from below the heart to the small abdomen, resembling abdominal fullness. However, Pi may remain confined to the epigastrium, whereas abdominal fullness is centered in the abdomen. When pathogens enter the interior and contend with healthy qi, abdominal pain occurs, hence the variations in pain. Abdominal pain belongs to interior syndromes. Taiyang disease does not involve abdominal pain; Shaoyang involves chest and hypochondriac pain without abdominal pain. Yangming disease involves urgent abdominal fullness and pain, indicating interior excess suitable for purgation, using Da Chaihu Tang (Major Bupleurum Decoction) or Xiao Chengqi Tang. Three Yin syndromes with clear undigested stool diarrhea and abdominal pain are due to interior cold. This summarizes the yin aspect within the Taiyang meridian, treated with Sini Tang (Bupleurum Decoction for Reversing Cold) or Fuzi Lizhong Tang (Aconite Decoction for Middle Regulating). When yang qi transmits to the Taiyin meridian causing abdominal fullness and pain, there are two types: excess pain and deficiency pain. Pain with borborygmus and diarrhea is deficiency pain. This specifically discusses the yang aspect within the Taiyin meridian, treated with Xiaojianzhong Tang, which is Guizhi Jia Shaoyao Tang, differing only in the dosage of Cinnamon Twig. If ineffective, use Xiao Chaihu Tang removing Scutellaria and adding Paeonia in equal amounts. Abdominal fullness, constipation, and tenderness upon pressure indicate excess pain, treated with Guizhi Tang adding one qian of Rhubarb. This distinction between deficiency and excess pain is based on the gradual dissipation of yang pathogens (deficiency) versus the abundance of yang qi (excess).
Wu Shou said: Abdominal pain that can be pressed or rubbed indicates interior deficiency; pain that cannot be pressed or rubbed indicates interior excess. Haizang stated that pain at the Zhongwan point belongs to the spleen earth. With a deep, slow pulse indicating interior cold, use Lizhong Tang or Fuzi Lizhong Wan. With a superficial choppy pulse and deep wiry pulse, use Xiaojianzhong Tang. Small abdominal pain belonging to the Jueyin meridian is treated with Danggui Sini Tang (Angelica Decoction for Reversing Cold) plus Evodia Fruit. For reversal cold, the same formula applies. For major excess abdominal fullness and pain, stabbing pain around the umbilicus, constipation, and a solid pulse, use Dachengqi Tang. For tidal fever, constipation, hardness/fullness/pain from the epigastrium to the small abdomen, and extreme tenderness, use Daxiexiong Tang (Major Chest-Binding Decoction). For wiry pulse abdominal pain without heat or cold, use Shaoyao Gancao Tang (Paeonia and Licorice Decoction). For wiry pulse, bitter taste, fever, and abdominal pain, use Xiao Chaihu Tang removing Ginseng and adding stir-fried Paeonia. For alternating chills and fever with abdominal pain, add Cinnamon Bark and Paeonia. For predominant cold with pain, remove Scutellaria and add Cinnamon Bark and Paeonia. For Shaoyin fever, cold extremities, and abdominal pain, use Sini San plus Aconite, Cinnamon, Evodia, and Paeonia. For fever, surging/wiry pulse, and abdominal pain, use Shaoyao Huangqin Tang (Paeonia and Scutellaria Decoction). Blood stasis also causes abdominal pain, extreme tenderness. Abdominal pain with urge to vomit/diarrhea and irritability often indicates sha toxin. Secular practice involves scraping the Weizhong acupoint.
Ke Qin said: Above Taiyin, dampness prevails. Abdominal pain, vomiting, and diarrhea transform from dampness. Thus, when humans are injured by dampness, the spleen is affected first. However, if cold-dampness invades the yin meridians without disturbing the zang organs, it returns to the stomach fu. The Taiyin meridian spreads through the stomach and manifests there. Cold-dampness in the stomach prevents food intake, causing vomiting and diarrhea. The Taiyin meridian enters the abdomen from the foot; cold qi ascends intermittently, causing spontaneous abdominal pain. The method should be to warm the middle and dispel cold. Erroneous purgation causes cold to injure the stomach opening, leading to hardness below the heart.
[General Principle] Zhang Zhongjing said: In Shanghan, if the pulse is floating and slow, and the hands and feet are naturally warm, the disease is associated with Taiyin. Taiyin disease typically presents with jaundice. However, if urination is free, jaundice will not develop. By the seventh or eighth day, although sudden irritability occurs and diarrhea happens more than ten times a day, it will necessarily stop spontaneously. This is because the spleen qi becomes sufficient (Shi), and the putrid filth is expelled.
[Detailed Commentary] Xu Shuwēi said: The *Nan Jing* states: Pain indicates excess. "Spleen excess" implies that true excess must involve pain. Generally, pain syndromes are suitable for purgation.
Cheng Wuji said: Abdominal fullness is a Taiyin syndrome. When yang-heat acts as the pathogen, there is abdominal fullness with a dry throat. When yin-cold acts as the pathogen, there is abdominal fullness, vomiting, inability to eat, worsening diarrhea, and spontaneous abdominal pain. Taiyin corresponds to spleen earth, which governs the center, thus primarily manifesting as abdominal fullness. Furthermore, abdominal fullness resulting from sweating, emesis, or purgation is caused by pathogens invading the interior due to deficiency, but the treatments differ. The classic states: Abdominal fullness after sweating is treated with Houpo Shengjiang Gancao Banxia Renshen Tang. Abdominal fullness after emesis in Shanghan is treated with Tiaowei Chengqi Tang. Abdominal fullness, restlessness, and irritability after purgation in Shanghan is treated with Zhizi Houpo Tang. These three require warming, purgation, or emesis respectively. Why? Because the pathogens differ. Sweating removes exterior pathogens, but excessive sweating depletes yang, causing stomach qi deficiency and failure to distribute, leading to qi stagnation and bloating; this requires warming and dispersing. Emesis removes pathogens from the chest; if successful, peace is restored. If unsuccessful, chest pathogens descend to the stomach becoming excess, causing bloating; this requires purgation. Erroneous purgation leaves exterior pathogens unentered into fu organs, which then invade the interior via deficiency, stagnating in the chest, causing empty irritability and blocked qi flow leading to abdominal bloating; this requires emesis. Physicians must identify the origin and nature of the pathogen, observe its location, and determine deficiency or excess, so that sweating, emesis, and purgation therapies will be effective.
Shen Jin'ao notes: "Spleen excess" refers to the expulsion of putrid filth.
[General Principle] Zhang Zhongjing said: In Shanghan, on the fourth or fifth day, if there is abdominal pain and gas moving downward toward the small abdomen, this is a sign of impending spontaneous diarrhea.
[Detailed Commentary] Ke Qin said: This is a precursor to spontaneous diarrhea. The fourth or fifth day is the period for Taiyin disease onset.
