是上部之病，非下部肠病，故禁下法也。惟心下硬痛，大便不通者，方用攻下。
脉浮而大，心下反硬，有热属脏者，攻之。
脉浮而大，不当攻。今心下反硬，有热属脏，形容热已深入，而结藏于里，故可攻之。
阳明病，心下硬满不可攻，攻之利遂不止。
前条浮大表脉，尚曰可攻。此条同一硬满，何曰不可攻？前条有有热属脏，内已包藏，便

伤寒五六日，大下之后，身热不可去，心下结痛者，未欲解也，栀子豉汤。
伤寒大下后，若身热去，心下结痛，此为结胸，当用陷胸汤。今身热不去，心下结痛，当

大便不通六七日，舌上燥而渴，日晡小有潮热，且心下至小腹硬满而痛，则成结胸症，故用陷胸汤。
栀连平胃散 即平胃散加栀连。
胃有湿热，故加栀，连湿郁成痰，加半夏、石菖蒲；若顽痰胶结，加海石、香附。

心下胀满，归属于阳明胃家。所以说邪气结聚于心下，出现胀满且心烦，感到饥饿却不想进食，心胸部位嘈杂不适，或者出现气逆作呕的症状，这是胃中有火，导致痰、食停滞积聚所致。适宜使用栀连平胃散、二陈汤调和服用。如果心下胀满但不觉得饿也不想吃东西，也没有嘈杂感，这是没有火的痰、食停滞积聚。如果是初起时恶心、胀痛，应当先用吐法，随后再用消食化痰的方法，不要使用苦寒药物来遏制病势。如果是热邪聚集在胃，导致心下痞塞胀满，才可以使用枳壳川连汤、栀连保和散，以清除热积；用栀连二陈汤来化解热痰。家传秘方使用保和散加入白豆蔻、砂仁来消除食滞引起的饱闷。如果体内有热，将凉药煎好后用汤剂调服，忌用燥性药物，冲服竹沥、莱菔汁最为巧妙。总之，胸前饱闷，适宜消导而不宜补益，适宜疏散而不宜收敛。如果有停滞，切忌使用寒凉生冷之物。如果胸前真有凝结，即使出现烦躁、谵语等症状，应当仔细辨别是食气、痰凝所致，千万不要误认为是里热导致的谵妄，从而错误地投用凉剂攻下。大凡胸痛、胃满，都是上部的疾病，不是下部肠道的病，所以禁止使用下法。只有当心下硬痛，大便不通时，才使用攻下法。
脉象浮而大，心下反而坚硬，有热邪属于脏者，可以攻下。
脉象浮而大，本不应攻下。现在心下反而坚硬，有热邪属于脏，形容热邪已经深入，结聚于里，所以可以攻下。
阳明病，心下硬满不可攻下，如果攻下，腹泻就会不止。
前一条提到浮大的表脉，还说可以攻下。这一条同样是硬满，为什么说不可攻下？前一条有“有热属脏”，内部已经包藏，导致大便硬、消水、口燥唇焦等种种里热症状，所以说可以攻下。这一条没有“有热属脏”，恐怕是食滞、痰饮导致的硬满。说这一条不可攻下，那么上一条就可以攻下，这样更有下手之处。
伤寒五六天，经过猛烈攻下之后，身体发热不退，心下结聚疼痛的，病尚未解除，使用栀子豉汤。
伤寒经过猛烈攻下后，如果身体发热退了，心下结聚疼痛，这是结胸证，应当使用陷胸汤。现在身体发热不退，心下结聚疼痛，应当使用柴胡汤。不用柴胡汤而用栀子豉汤的原因，是因为发汗、攻下之后，身体发热、心里烦闷，心下结聚疼痛罢了。
太阳病，重发汗，又攻下它，六七天不大便，舌上干燥而口渴，傍晚时分有轻微潮热，从心下直到小腹硬满而痛，以大陷胸汤为主治方。
这里区分同样是攻下之后，上一条身热不退，心下结聚疼痛，与这一条傍晚潮热，小腹硬痛，治疗分为上部和下部。大便不通六七天，舌上干燥而口渴，傍晚有轻微潮热，且从心下到小腹硬满而痛，这就形成了结胸证，所以使用陷胸汤。
栀连平胃散 即平胃散加上栀子、黄连。
胃有湿热，所以加栀子、黄连；湿郁结成痰，加半夏、石菖蒲；如果是顽痰胶结，加海浮石、香附。
二陈汤
熟半夏 白茯苓 广陈皮 甘草 加石菖蒲
治疗痰症使用二陈汤，是不变的理论。然而顽痰胶结，非南星、石菖蒲不能开通郁痰成积；非海浮石、香附不能解痰食相凝，必须与保和丸合用。二陈汤，治疗痰病的缓症；导痰汤、指迷丸、化痰丸，则稍重；控涎丹、滚痰丸则更重。要知道应用控涎丹、滚痰丸的病症，不仅是二陈汤不及，就是用指迷丸、化痰丸也不及。应用二陈汤的病症，不仅是控涎丹、滚痰丸太过，就是指迷丸、化痰丸也太过。
枳壳川连汤 两味药。
此方加木香，能治疗湿热下利；加当归、大黄，能治疗燥热下血，腹痛频繁并见。现在因为心下满闷也用此方，因为枳壳与川连同用，能消除心下热结之痞。如果痰涎凝结，加半夏、栝蒌实，就合成了小陷胸汤。加广陈皮、厚朴、竹茹，能清胃热而止呕吐；加大黄、甘草，又合成了调胃承气汤。
栀子豆豉汤 两味药。
仲景治疗心胸满闷，如果表症还在，仍然用发表法。表邪已解，里有热结的，用诸泻心汤。心腹硬痛，有下症的，用陷胸汤。如果在发汗、攻下之后，心烦痞塞，立即用栀子豉汤，和解其热；栀子厚朴汤，宽解其气，这是无穷的法门。
大陷胸汤 见结胸篇。
按：大陷胸汤，治疗心下硬痛，大实大满。小陷胸汤，治疗热痰凝结中焦。枳壳川连汤、栀子厚朴汤，治疗热邪凝结气分。栀子豆豉汤，治疗发汗、攻下后烦热痞塞。诸泻心汤，治疗因误用寒药攻下，抑遏痰热于胸前，这是丝丝入扣的法门。
Epigastric fullness belongs to the Yangming Stomach system. Therefore, it is said that pathogenic factors are knotted in the epigastrium, causing fullness and irritability; the patient feels hungry but has no desire to eat, experiences a sensation of discomfort (Zaocha) in the chest and heart, or may present with rebellious Qi leading to vomiting. This indicates Phlegm and Food retention due to Fire in the Stomach. It is appropriate to administer Zhilian Pingwei San (Gardenia and Coptis Pingwei Powder) and Erchen Tang (Two-Cured Decoction) harmoniously. If there is epigastric fullness without hunger or desire to eat, and without Zaocha, this indicates Phlegm and Food retention without Fire. If initially there is nausea, distension, and pain, emesis should be induced first, followed by methods to digest food and resolve phlegm; bitter-cold drugs should not be used to suppress the pathogen. If Heat pathogens gather in the Stomach, causing epigastric stuffiness and fullness, Zhike Chuanlian Tang (Immature Bitter Orange and Coptis Decoction) or Zhilian Baohe San (Gardenia and Coptis Harmonize the Middle Powder) can be used to clear Heat accumulation, and Zhilian Erchen Tang (Gardenia, Coptis, and Two-Cured Decoction) to resolve Phlegm-Heat. A secret prescription uses Baohe San (Harmonize the Middle Powder) added with Bai Doukou (White Cardamom) and Sharen (Amomum Fruit) to eliminate Food stagnation causing fullness and oppression. If there is Heat inside, decoct cold medicines and take them mixed with liquid; dry substances are contraindicated. Mixing with Zhuli (Bamboo Sap) and Laifu Zhi (Radish Juice) is excellent. In summary, for fullness and oppression in the chest, resolution is preferred over tonification, and dispersion is preferred over consolidation. If there is stagnation, cold and raw foods must be strictly avoided. If there is true condensation in the chest, even if symptoms such as irritability and delirium appear, one must carefully distinguish whether it is caused by Food Qi or Phlegm condensation. Do not mistakenly diagnose it as delirium due to Interior Heat and erroneously administer cold purgatives. Generally, chest pain and stomach fullness are diseases of the Upper Jiao, not diseases of the Lower Jiao intestines; therefore, purgative methods are contraindicated. Only when the epigastrium is hard and painful, accompanied by constipation, should purgative methods be used.
A pulse that is floating and large, with the epigastrium conversely becoming hard, and Heat belonging to the Zang organs, indicates that purgation is indicated.
A pulse that is floating and large should not normally be treated with purgation. Now that the epigastrium is conversely hard, and Heat belongs to the Zang organs, this describes Heat that has penetrated deeply and is knotted in the Interior; thus, purgation is permissible.
Yangming disease, with hardness and fullness in the epigastrium, must not be treated with purgation. If purged, diarrhea will ceaselessly continue.
The previous clause mentioned a floating-large exterior pulse and stated that purgation could be used. This clause presents the same hardness and fullness but states purgation is contraindicated. The previous clause had "Heat belonging to the Zang," implying internal storage, leading to hard stool, water-drinking behavior, dry mouth, and scorched lips—various Interior Heat symptoms—hence "purge." This clause lacks "Heat belonging to the Zang" and likely involves Food stagnation or Phlegm-fluid causing hardness and fullness. Stating this clause is contraindicated for purgation clarifies that the previous clause was amenable to treatment, providing clearer guidance.
After five or six days of Cold Damage, following severe purgation, if body heat persists and there is knotting and pain in the epigastrium, the disease has not yet resolved; use Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction).
After severe purgation in Cold Damage, if body heat subsides but knotting and pain remain in the epigastrium, this is Jie Xiong (Chest Binding), and Xianxiong Tang (Trap-the-Chest Decoction) should be used. Now, since body heat persists and there is knotting and pain in the epigastrium, Chaihu Tang (Bupleurum Decoction) should be used. The reason for using Zhizi Chi Tang instead of Chaihu Tang is that after sweating and purging, there is body heat, interior irritability, and knotting/pain in the epigastrium.
Taiyang disease, after excessive sweating and subsequent purgation, if there is no bowel movement for six or seven days, the tongue is dry and thirsty, there is slight tidal fever in the late afternoon, and from the epigastrium down to the lower abdomen there is hardness, fullness, and pain, Da Xianxiong Tang (Major Trap-the-Chest Decoction) is the primary formula.
This distinguishes cases following purgation: the previous case had persistent body heat and epigastric knotting/pain, while this case has late-afternoon tidal fever and lower abdominal hardness/pain, indicating treatment directed at the upper versus lower regions. With constipation for six or seven days, dry tongue with thirst, slight late-afternoon tidal fever, and hardness/fullness/pain from the epigastrium to the lower abdomen, this constitutes a Jie Xiong syndrome; thus, Xianxiong Tang is used.
Zhilian Pingwei San is Pingwei San added with Zhizi (Gardenia) and Lian (Coptis).
For Damp-Heat in the Stomach, add Zhizi and Lian; for Dampness stagnating into Phlegm, add Banxia (Pinellia) and Shichangpu (Acorus); for stubborn Phlegm adhesion, add Haishi (Pumice) and Xiangfu (Cyperus).
Erchen Tang
Prepared Banxia (Pinellia) Baifuling (Poria) Guangpi (Tangerine Peel) Gancao (Licorice) Add Shichangpu (Acorus)
Using Erchen Tang for Phlegm diseases is an unchanging principle. However, for stubborn Phlegm adhesion, only Nanxing (Arisaema) and Shichangpu can open depressed Phlegm to resolve masses; only Haishi and Xiangfu can resolve the conglomeration of Phlegm and Food; they must be combined with Baohe Wan (Harmonize the Middle Pill). Erchen Tang treats mild Phlegm diseases; Daotan Tang (Guide-out Phlegm Decoction), Zhimi Wan (Point-to-Mystery Pill), and Huatan Wan (Resolve-Phlegm Pill) are slightly heavier; Kongxian Dan (Drain-Fluid Pellet) and Guntan Wan (Roll-Phlegm Pill) are heavy. One must know that for conditions requiring Kongxian Dan or Guntan Wan, not only is Erchen Tang insufficient, but Zhimi Wan and Huatan Wan are also insufficient. Conversely, for conditions requiring Erchen Tang, not only are Kongxian Dan and Guntan Wan too strong, but Zhimi Wan and Huatan Wan are also too strong.
Zhike Chuanlian Tang consists of two ingredients.
Adding Muxiang (Aucklandia) to this formula treats Damp-Heat dysentery; adding Danggui (Angelica) and Dahuang (Rhubarb) treats Dry-Heat hematochezia with frequent abdominal pain. Currently, it is used for epigastric fullness and oppression because Zhike and Chuanlian together can resolve epigastric Heat-knot stuffiness. If Phlegm-saliva is condensed, add Banxia and Gualou Shi (Trichosanthes Seed) to form Xiao Xianxiong Tang (Minor Trap-the-Chest Decoction). Adding Guangpi, Houpo (Magnolia Bark), and Zhuru (Bamboo Shavings) clears Stomach Heat and stops vomiting; adding Dahuang and Gancao forms Tiaowei Chengqi Tang (Regulate-the-Stomach and Restore-Qi Decoction).
Zhizi Chidui Tang consists of two ingredients.
Zhongjing treated chest and heart fullness by still using exterior-releasing methods if exterior symptoms persisted. If exterior pathogens were resolved but Interior Heat knots remained, various Xiexin Tangs (Drain-the-Epigastrium Decoctions) were used. For hardness and pain in the heart and abdomen with purgative indications, Xianxiong Tang was used. If after sweating and purging, there was irritability and stuffiness, Zhizi Chi Tang was immediately prescribed to harmonize Heat; Zhizi Houpo Tang (Gardenia and Magnolia Decoction) was used to broaden and relieve Qi. These are endless methods.
Da Xianxiong Tang See Jie Xiong (Chest Binding).
Note: Da Xianxiong Tang treats epigastric hardness and pain, representing major excess and fullness. Xiao Xianxiong Tang treats Heat-Phlegm condensation in the Middle Jiao. Zhike Chuanlian Tang and Zhizi Houpo Tang treat Heat-pathogen condensation in the Qi level. Zhizi Chidui Tang treats irritability, heat, and stuffiness after sweating and purging. Various Xiexin Tangs treat cases where erroneous use of cold medicines for purgation suppressed Phlegm-Heat in the chest. These methods are meticulously applied.
