（出自刘完素《宣明论方》）治疗风热邪气壅盛，气血郁滞不畅，表里及三焦均呈实证的患者；同时也用于治疗：
防风、连翘、麻黄、薄荷、川芎、当归、白芍、大黄、芒硝（各五钱）、白术、荆芥、黑山栀（各一分）、黄芩、石膏、桔梗（各一两）、甘草（二两）、滑石（三两）。将上述药物研为细末，每次服用二钱，加入生姜煎煮。（汪昂在《医方集解》中去掉了大黄和芒硝，将此方命名为双解散。）
防风通圣散是由凉膈散演变而来，去除了竹叶和白蜜，并增加了发散表邪、调和气血的药物。方中麻黄、桔梗、荆芥、防风、滑石、石膏、川芎、当归、白术、白芍以及生姜具有协同作用。其中，荆芥、防风、麻黄、薄荷能发汗以疏散热搜之风邪；栀子、滑石、芒硝、大黄能通利二便以降火行水；黄芩、桔梗、石膏能清泻肺胃之火；川芎、当归、白芍能养血以补益肝脏；连翘能消散气聚血凝之结；甘草、白术能补益中气、燥湿健脾；生姜能通达表里，使得发汗不伤表阳，攻下不伤里气。此方名为“通圣”，是因为它能全面消除疮疡痈毒。（疮疡肿毒，也是由风热壅盛、气血郁滞所导致。）如果去掉芒硝和大黄，该方依然能起到表里双解的作用，对于大便不干硬者适宜使用。
治疗太阳中风证，伴有腹泻、呕吐逆气等症状，待表证解除后，方可使用攻下法。患者出现濈然汗出、头痛、心下部硬满疼痛、牵引胁下作痛、干呕、呼吸短促、出汗且不恶寒的情况，这属于表证已解而里气未和。此外，也用于治疗饮水后水液停留于胁下，咳嗽吐痰时牵引胸中疼痛的症状，称为悬饮。其脉象沉而弦，若不及时救治不会立即死亡，但病程可能持续百日或一年。
芫花（炒至黑色）、甘遂、京大戟（等分）、大枣（十枚）。将各药分别捣碎研成细末。用水一升半，先煮大枣，取汁八合，滤去药渣，加入其余药物的粉末。体质强壮者服用一钱，体质虚弱者服用五分。服药后若得快速通便，应食用糜粥来自我调养。
(From Liu Wansu's *Xuanming Lunfang*) Treats patients with excessive wind-heat pathogen stagnation, qi and blood constraint, and excess conditions in the exterior, interior, and Sanjiao (Triple Burner); also treats:
Fangfeng Radix Saposhnikoviae, Lianqiao Forsythiae Fructum, Mahuang Ephedrae Herba, Bohe Menthae Haplocalycis Herba, Chuanxiong Rhizoma Chuanxiong, Danggui Radix Angelicae Sinensis, Baishao Radix Paeoniae Alba, Dahuang Rhei Radix et Rhizoma, Mangxia Natrii Sulfas, Baizhu Atractylodis Macrocephalae Rhizoma, Jingjie Perillae Folium, Heishanzhi Gardeniae Fructus (each 5 qian), Huangqin Scutellariae Radix, Shigypsum Fibrosum, Jiegeng Platycodonis Radix (each 1 liang), Gancao Glycyrrhizae Radix et Rhizoma (2 liang), Huashi Talcum (3 liang). Grind into powder. Take 2 qian per dose, decoct with fresh ginger slices. (Wang Ang in *Yifang Jijie* removes Dahuang and Mangxia, naming this formula Shuangjie San.)
Fangfeng Tongsheng San is a modification of Liangge San, removing Zhuye (Bambusae Folium) and Baimi (White Honey), and adding herbs that release the exterior and harmonize qi and blood. Mahuang, Jiegeng, Jingjie, Fangfeng, Huashi, Shigypsum, Chuanxiong, Danggui, Baizhu, Baishao, and Shengjiang (Fresh Ginger Rhizome) work synergistically. Jingjie, Fangfeng, Mahuang, and Bohe induce sweating to disperse wind-heat; Zhizi, Huashi, Mangxia, and Dahuang promote urination and defecation to descend fire and move water; Huangqin, Jiegeng, and Shigypsum clear and purge lung and stomach heat; Chuanxiong, Danggui, and Baishao nourish blood to tonify the liver; Lianqiao dissipates qi stagnation and blood coagulation; Gancao and Baizhu tonify the middle jiao and dry dampness; Shengjiang penetrates both exterior and interior, ensuring that sweating does not damage the exterior and purging does not damage the interior. Named "Tongsheng" (Thoroughly Sacred/Effective), it can completely eliminate sores, ulcers, carbuncles, and toxins. (Sores and ulcers are also caused by wind-heat stagnation and qi-blood constraint.) Removing Mangxia and Dahuang still allows for simultaneous resolution of exterior and interior conditions, suitable for those with non-hard stools.
Treats Taiyang Wind Strike syndrome accompanied by diarrhea and vomiting/reversal of qi. After the exterior syndrome is resolved, attack methods may be used. If the patient presents with continuous sweating, headache, hardness and fullness below the heart radiating pain to the hypochondrium, dry retching, shortness of breath, sweating without aversion to cold, this indicates the exterior is resolved but the interior is disharmonious. It also treats fluid retention in the hypochondrium after drinking, where coughing and expectoration pull on pain in the chest, known as Xuan Yin (Hanging Fluid). The pulse is deep and wiry. Without sudden death, the condition may persist for one hundred days or a year.
Yuanhua Genkwa Flos, Gansui Kansui Radix, Daji Euphorbiae Pekinensis Radix (equal parts), Dazao Jujubae Fructus (10 pieces). Pound each herb separately into powder. Use 1.5 sheng of water, first decoct Dazao until reduced to 0.8 sheng, filter out the dregs, and add the powders of the other herbs. Strong individuals take 1 qian; weak individuals take 0.5 qian. After rapid purgation, self-nourish with millet porridge.
