寒实结胸，结胸皆系热陷之症，此云∶寒实。乃水气寒冷所结之痰饮也。无热证者，与三物小陷胸汤，

即小承气加芍药、二仁也。
麻子仁（二升） 芍药 枳实（各半斤，炙） 大黄（一斤，去皮） 浓朴（一尺，炙去皮） 杏仁（一升，去皮

趺阳脉浮而涩，浮则胃气强，阳盛。涩则小便数，阴不足。浮涩相搏，大便则硬，其脾为约。此即论
中所云∶太阳，阳明者，脾约是也。麻仁丸主之。太阳正传阳明，不复再传，故可以缓法治之。

之。汗后而邪未尽，必有留饮在心下。其症甚杂，而方中诸药，一一对症，内中又有一药治两症者、亦有
两药合治一症者，错综变化，攻补兼施，寒热互用。皆本《内经》立方诸法，其药性又有与《神农本草》
所载无处不合。学人能于此等方讲求其理，而推展之，则操纵在我矣。
凡泻心诸法，皆已汗、已下、已吐之余疾。
桔梗、贝母（各三分，古法规定二钱五分为一分）、巴豆（一分，去皮去心，炒至变黑，研成脂状）。以上三味药，制成散剂，加入巴豆，继续在臼中捣匀。用米汤送服，体质强壮的人服用半钱匕的量，按现在的秤约重三分；体弱的人减少剂量。病位在膈上者必然呕吐，病位在膈下者必然腹泻。如果服药后没有腹泻，喝一碗热粥以助药力；如果腹泻不止，喝一碗冷粥以止泻。巴豆遇热则药效发挥，遇冷则药效停止。如果身体发热、皮肤起粟粒感而症状未解，怕冷并出现寒栗，想要拉衣服遮盖自己，如果用冷水浇洗，只会使热邪被遏制而无法发散，应当出汗却出不了汗，从而导致烦躁。假如服药后已经出汗，但腹部疼痛，给予芍药三两，用法同上。
所谓寒实结胸，一般的结胸证都是热邪内陷所致，这里所说的“寒实”，是指水气寒冷所凝结的痰饮。如果没有热象，可以给予三物小陷胸汤，白散也可以使用。按：《活人书》中说：“给予三物白散”，没有“小陷胸汤亦可用”这七个字，大概是因为小陷胸汤是寒凉之剂，不适合用于无热证的病症。
（麻仁丸）即是在小承气汤基础上加上芍药和两种仁类药材组成。
麻子仁（二升）、芍药、枳实（各半斤，炙烤）、大黄（一斤，去皮）、浓朴（一尺，炙烤去皮）、杏仁（一升，去皮尖，炒熟后单独研成脂状）。以上六味药，制成粉末，用炼蜜调和做成梧桐子大小的丸剂，每次用水送服十丸，每日三次，逐渐增加剂量，以见效为度。
趺阳脉浮而涩，浮脉表示胃气强盛，阳气偏盛；涩脉表示小便频数，阴液不足。浮脉与涩脉相搏结，导致大便干硬，这就是脾脏功能受限（脾约）。这正是《伤寒论》中所说的：太阳病传入阳明病，属于脾约证。使用麻仁丸主治。太阳病直接传变为阳明病，不再继续传变，因此可以用缓和的方法治疗。
生姜（四两，切片）、甘草（炙烤）、人参、黄芩（各三两）、半夏（半升，洗净）、黄连、干姜（各一两）、大枣（十二枚，掰开）。以上八味药，用水一斗，煮取六升药液。去掉药渣，再次煎煮，取三升药液，每次温服一升，每日三次。
伤寒经过发汗治疗后，表证已解，但胃中不和，心下部痞塞坚硬，嗳气带有食物腐臭味，胁下有停饮，肠鸣音亢进并伴有腹泻的，使用生姜泻心汤主治。发汗后邪气未尽，必然有留饮停留在心下。其症状非常复杂，而方中的药物，每一味都对症，其中有的药物能治疗两种症状，也有两种药物配合治疗一种症状，错综变化，攻补兼施，寒热并用。这些方法都依据《内经》立方的各种法则，药物的性味又与《神农本草经》所载完全吻合。学习中医的人如果能在此类方剂中探究其原理，并加以推演拓展，就能掌握治疗的主动权了。
凡是泻心汤类的治法，都是针对已经发汗、已经攻下、已经催吐之后遗留的余疾。
Jiegeng (Platycodonis Radix), Beimu (Fritillariae Bulbus) (each 3 fen; in ancient methods, 2 qian 5 fen equals 1 fen), Badou (Crotonis Fructus) (1 fen, peeled, heart removed, stir-fried until black, ground into a paste). The above three ingredients are made into a powder. Add Badou and continue to pound in a mortar. Take with rice water (Bai Yin). For strong individuals, take half a Qianbi dose (approximately 3 fen by modern weighing); for frail individuals, reduce the dose. If the disease is located above the diaphragm, vomiting will inevitably occur; if below the diaphragm, diarrhea will inevitably occur. If there is no diarrhea after taking the medicine, drink one bowl of hot porridge to promote the effect; if diarrhea persists excessively, drink one bowl of cold porridge to stop it. Badou acts when heated and stops when cooled. If body heat and skin pruritus (pi su) do not resolve, accompanied by aversion to cold and shivering (han su), with a desire to cover oneself with clothes, using water to wash or pour over the body will only further trap the heat, preventing its release. Sweat should occur but does not, leading to irritability (fan). If sweating occurs after administration but abdominal pain follows, administer Shaoyao (Paeoniae Radix Alba) 3 liang according to the aforementioned method.
The so-called Cold-Shi Jie Xiong (Cold-Excess Chest Binding): generally, Jie Xiong syndromes are caused by heat sinking inward. Here, "Cold-Shi" refers to phlegm-fluid retention condensed by cold qi and coldness. In the absence of heat signs, Sanwu Xiaoxin Tang (Three-Ingredient Minor Bitter Pill Decoction) can be given; Baisan (White Powder) is also applicable. Note: *Huoren Shu* states: "Administer Sanwu Baisan," omitting the seven characters "Xiaoxin Tang may also be used." This is likely because Xiaoxin Tang is a cold-natured formula, unsuitable for conditions without heat.
(Maren Wan) consists of Xiao Chengqi Tang plus Shaoyao and two types of seeds.
Maziren (Semen Cannabis) (2 sheng), Shaoyao (Paeoniae Radix), Zhishi (Aurantii Fructus Immaturus) (each 0.5 jin, prepared by stir-frying), Dahuang (Rhei Radix et Rhizoma) (1 jin, peeled), Houpo (Magnoliae Officinalis Cortex) (1 chi, prepared by stir-frying and peeled), Xingren (Semen Armeniacae Amarum) (1 sheng, peeled, tips removed, stir-fried and separately ground into a paste). The above six ingredients are powdered. Mix with refined honey to form pills the size of wutong seeds. Take ten pills with water, three times daily. Gradually increase the dose until therapeutic effect is achieved.
The Fuyang pulse is floating and choppy (se). A floating pulse indicates strong stomach qi and excess yang; a choppy pulse indicates frequent urination and insufficient yin. The interaction of floating and choppy pulses leads to hard stools, known as Pi Yue (Spleen Constriction). This corresponds to the statement in the treatise: "Taiyang transmitting to Yangming constitutes Pi Yue." Maren Wan is the primary formula. Since Taiyang transmits directly to Yangming without further transmission, gentle treatment methods can be employed.
Shengjiang (Zingiberis Rhizoma Recens) (4 liang, sliced), Gancao (Glycyrrhizae Radix et Rhizoma, prepared by stir-frying), Renshen (Ginseng Radix), Huangqin (Scutellariae Radix) (each 3 liang), Banxia (Pinelliae Rhizoma) (0.5 sheng, washed), Huanglian (Coptidis Rhizoma), Ganjiang (Zingiberis Rhizoma) (each 1 liang), Dazao (Jujubae Fructus) (12 pieces, torn open). The above eight ingredients are boiled in 1 dou of water to obtain 6 sheng of liquid. Remove dregs, decoct again to obtain 3 sheng. Take 1 sheng warm, three times daily.
After treating Shanghan (Cold Damage) with sweating therapy, once the exterior syndrome resolves but the stomach interior remains disordered, presenting with epigastric fullness and hardness, belching with food odor, fluid retention under the costal region, borborygmus, and diarrhea, Shengjiang Xiexin Tang (Ginger Heart-Draining Decoction) is indicated. After sweating, if pathogens remain incomplete, lingering fluids must reside in the epigastrium. The symptoms are complex; however, each herb in the formula targets specific symptoms. Some herbs treat two symptoms, while combinations of two herbs treat one symptom. There is intricate variation, combining purgation and tonification, and using cold and hot properties together. These methods are based on the prescription principles of *Neijing* (Inner Canon), and the properties of the herbs align perfectly with those recorded in *Shennong Bencao Jing* (Divine Farmer's Materia Medica). Practitioners who study the principles behind such formulas and apply them flexibly will master therapeutic control.
All methods involving Xiexin (Heart-Draining) formulas address residual ailments following prior sweating, purging, or emesis.
