主治肠胃间积滞的寒邪导致的腹泻和腹痛。应当先攻逐去除这些积滞，然后再进行调理治疗。不要因为担心身体虚弱而迁延病情、助长病邪。
温脾汤由桂心、附子、干姜组成，配合厚朴、甘草，并佐以大黄使用。如果腹泻缠绵不愈，说明是顽固性的寒邪。温补与通下并用，疗效非常显著。（方中附子、干姜、甘草、桂心、厚朴各二钱，大黄四分。用水两杯，煎煮至六分，服用。）
喻嘉言说：许叔微制定这个方子，深得张仲景“用温药攻下”的法则精髓。方中大黄这一味药如果不使用，那么温热的药物就不能起到攻下的作用，而久留体内的邪气，非攻逐不能去除。但如果用量过多，恐怕温热之药无法制约大黄的寒性，导致腹泻加剧甚至转为严重的洞泄。因此斟酌剂量使用，真是值得效法的典范。
风热邪气壅盛，表里三焦都呈现实证。○采用解表与攻里并用的方法。
防风通圣散（刘河间制）。方中包含大黄、芒硝、荆芥、麻黄、栀子、白芍、连翘、甘草、桔梗、川芎、当归、石膏、滑石、薄荷、黄芩、白术，药力颇强。（方中大黄酒蒸、芒硝、防风、荆芥、麻黄、栀子、白芍、连翘、川芎、当归、薄荷、白术各五分；桔梗、黄芩、石膏各一钱；甘草二钱；滑石三钱。加入生姜、葱白煎服。）
吴鹤皋说：防风、麻黄是解表的药物。停留在皮肤的风热邪气，得到此药后通过汗液排出。荆芥、薄荷是清上焦的药物。停留在头顶的风热邪气，得到此药后通过鼻腔排出。大黄、芒硝是通利的药物。停留在肠胃的风热邪气，得到此药后通过大便排出。滑石、栀子利水道的药物。停留在决渎（三焦水道）的风热邪气，得到此药后通过小便排出。风邪侵犯膈部，肺胃受邪，石膏、桔梗能清肺胃之火。而连翘、黄芩又能祛除各条经络中的游火。风的致病，由肝木所主，川芎、当归、白芍能调和肝血。而甘草、白术能调和胃气并健脾。刘守真氏擅长治疗火证，这个方子的宗旨，详尽且周密啊。它也用于治疗发斑症，属于三焦火实之证。全方去掉硝黄（芒硝、大黄）后名为双解散。其中解表的有防风、麻黄、薄荷、荆芥、川芎；解里的有石膏、滑石、黄芩、栀子、连翘。又有当归、芍药来调和血液，桔梗、白术、甘草来调畅气机。营卫调和，表里通畅，所以称为双解。本方名为通圣，极言其功效的神妙。
河间先生制定此方，用于解除四季时行之邪。无论是冬日的寒邪、春日的温邪、夏日的热邪还是秋日的燥邪，凡是正令伤寒，邪气在太阳、阳明、少阳三阳经，表里不解者，以一两半为剂量，加生姜、葱白、淡豆豉煎服。等待汗法和下法同时起效，表里之邪随即解除。形体正气强者，用一两半为剂量；形体正气弱者，用五钱为剂量。如果初次服药因出汗少而病不解，说明是表实，加倍增加麻黄以发汗；如果因大便硬结而不解，说明是里实，加倍增加芒硝、大黄以攻下。连续服用两剂，务必令患者汗出、下利而后病解。如今的人不知道其中的奥妙，认为河间先生过于使用寒凉药物，而张仲景治伤寒初期原本没有下法，于是弃置不用，真是可惜。他们不知道此法神速敏捷，没有不应手取效的，从未出现过寒邪内结痞块的变证。即使有一两个未能痊愈的，也不是方子不好，而是病邪一定已经传入阳明经了。
Indicated for diarrhea and abdominal pain caused by entrenched cold stagnation in the intestines and stomach. The stagnation should first be purged and removed, followed by regulatory treatment. One must not hesitate to treat due to fear of deficiency, thereby nourishing the disease.
Wenpi Tang (Warm the Spleen Decoction) consists of Guixin (Cinnamon Twig), Fuzi (Aconite Root), and Ganjiang (Dried Ginger), assisted by Houpo (Magnolia Bark), Gancao (Licorice Root), and supplemented with Dahuang (Rhubarb). If diarrhea persists and lingers, it indicates entrenched cold. The combination of warming and purging yields extraordinary efficacy. (Formula: Fuzi, Ganjiang, Gancao, Guixin, and Houpo each 2 qian; Dahuang 4 fen. Decoct in 2 cups of water until 0.6 cup remains, then take.)
Yu Jiayan stated: Xu Shuwei formulated this prescription, deeply aligning with Zhang Zhongjing's principle of "using warm herbs to purge." Without Dahuang in the formula, the warm herbs cannot achieve a purgative effect, and pathogens lingering for a long time cannot be expelled without attack. However, excessive use might overwhelm the warm herbs' control, potentially worsening the diarrhea into severe watery discharge. Therefore, careful dosage adjustment is truly worthy of emulation.
Wind-heat accumulation is severe, presenting as excess patterns in both the exterior and interior, involving all three Jiaos. ○ This method employs simultaneous release of the exterior and purging of the interior.
Fengtong Tongsheng San (Wind-Blocking Unblocking Holy Powder, Liu Hejian). It contains Dahuang (Rhubarb), Xiaoshao (Mirabilite), Jingjie (Schizonepeta), Mahuang (Ephedra), Zhizi (Gardenia), Baishao (White Peony Root), Lianqiao (Forsythia), Gancao (Licorice), Jiegeng (Platycodon), Chuanxiong (Szechwan Lovage Rhizome), Danggui (Angelica Sinensis), Shigao (Gypsum), Huashi (Talcum), Bohe (Mint), Qin (Scutellaria), and Baizhu (Atractylodes Macrocephala Rhizome), possessing strong potency. (Formula: Dahuang [wine-processed], Xiaoshao, Fengfang, Jingjie, Mahuang, Zhizi, Baishao, Lianqiao, Chuanxiong, Danggui, Bohe, Baizhu each 5 fen; Jiegeng, Huangqin, Shigao each 1 qian; Gancao 2 qian; Huashi 3 qian. Decoct with fresh ginger and scallion.)
Wu Hegao said: Fengfang and Mahuang are exterior-releasing herbs. Wind-heat residing in the skin is expelled through sweat upon taking these. Jingjie and Bohe are upper-clearing herbs. Wind-heat residing at the vertex is expelled through the nose. Dahuang and Xiaoshao are purgative herbs. Wind-heat residing in the intestines and stomach is expelled through defecation. Huashi and Zhizi are diuretic herbs. Wind-heat residing in the Jue Du (San Jiao water passages) is expelled through urination. When wind invades the diaphragm, affecting the Lung and Stomach, Shigao and Jiegeng clear Lung and Stomach heat. Meanwhile, Lianqiao and Huangqin dispel wandering fire from various meridians. Pathogenic wind is governed by Liver Wood; Chuanxiong, Danggui, and Baishao harmonize Liver blood. Gancao and Baizhu harmonize Stomach Qi and strengthen the Spleen. Liu Shouzhen was skilled in treating Fire patterns; the intent of this formula is detailed and comprehensive. It also treats macules resulting from hair loss, indicative of excess Fire in the Three Jiaos. The complete formula minus Xiaoshao and Dahuang is called Shuangjie San (Double Release Powder). For releasing the exterior, it uses Fengfang, Mahuang, Bohe, Jingjie, and Chuanxiong; for releasing the interior, it uses Shigao, Huashi, Huangqin, Zhizi, and Lianqiao. Additionally, Danggui and Baishao harmonize Blood, while Jiegeng, Baizhu, and Gancao regulate Qi. With Ying and Wei harmonized and the exterior and interior unobstructed, it is called Double Release. The name Tongsheng emphasizes the miraculous efficacy of its action.
Hejian formulated this to resolve pathogenic factors across the four seasons: winter cold, spring warmth, summer heat, and autumn dryness. In cases of standard Shanghan (Cold Damage) where pathogens remain unresolved in the Taiyang, Yangming, and Shaoyang meridians (Exterior and Interior), use 1.5 liang as a dose, decocted with fresh ginger, scallion, and Danchi (Fermented Soybean). Wait for sweating and purging to occur simultaneously, resolving the Exterior and Interior. For individuals with strong constitution, use 1.5 liang; for those with weak constitution, use 5 qian. If the initial dose fails to resolve symptoms due to insufficient sweating, it indicates Exterior Excess; double the Mahuang to induce sweating. If it fails due to hard stools, it indicates Interior Excess; double Xiaoshao and Dahuang to purge. Administer two consecutive doses until sweating and bowel movement occur, resolving the condition. Modern practitioners fail to understand its brilliance, arguing that Hejian overuses cold-cooling herbs and that Zhang Zhongjing initially avoided purgatives in Shanghan. Consequently, they discard it, which is truly regrettable. They do not realize the method's speed and efficacy, which rarely fail to produce immediate results, and never cause complications of cold-induced palpable masses. Even if one or two cases fail to recover, it is not due to the formula's inadequacy but rather because the pathogen has likely transmitted to the Yangming meridian.
