风、寒、暑、湿之气，入于皮肤之间而未深，欲速去之，莫如发汗。圣人之刺热
五十九刺，为无药而设也，皆所以开玄府而逐邪气，与汗同。然不若以药发之，使一毛一窍，无
不启发之为速也。
然发汗亦有数种。世俗止知惟温热者为汗药，岂知寒凉亦能汗也，亦有熏
渍而为汗者，亦有导引而为汗者。如桂枝汤、桂枝麻黄各半汤、五积散、败毒散，皆发汗甚热之药也
。如升麻汤、葛根汤、解肌汤、逼毒散，皆辛温之药也。如大柴胡汤、小柴胡汤、柴胡饮子，苦寒
之药也。如通圣散、双解散、当归散子，皆辛凉之药也。故外热内寒宜辛温，外寒内热宜辛凉。平
准所谓导引而汗者，华元化之虎、鹿、熊、猴、鸟五禽之戏，使汗出如敷粉，百疾皆愈。所谓熏渍而
汗者，如张苗治陈廪丘，烧地布桃叶蒸之，大汗立愈。又如许胤宗治许太后感风不能言，作防风汤数
斛，置于床下，气如烟雾，如其言，遂愈能言。此皆前人用之有验者。
以《本草》校之，荆
芥、香白芷、陈皮、半夏、细辛、苍术，其辛而温者乎；蜀椒、胡椒、茱萸、大蒜，其辛而
大热者乎；生姜，其辛而微温者乎；天麻、葱白，其辛而平者乎；青皮、薄荷，其辛苦而温
者乎；防己、秦艽，其辛而且苦者乎；麻黄、人参、大枣，其甘而温者乎；葛根、赤茯苓，
其甘而平者乎；桑白皮，其甘而寒者乎；防风、当归，其甘辛而温者乎；附子，其甘辛而大热者
乎；官桂、桂枝，其甘辛而大热者乎；浓朴，其苦而温者乎；桔梗，其苦而微温者乎；黄芩
、知母、枳实、地骨皮，其苦而寒者乎；前胡、柴胡，其苦而微寒者乎；羌活，其苦辛而微
温者乎；升麻，其苦甘且平者乎；芍药，其酸
而微寒者乎；浮萍，其辛酸而寒者乎；凡此四十味，皆发散之属也。
惟不善择者，当寒而反
热，当热而反寒，此病之所以变也。仲景曰∶大法春夏宜汗。春夏阳气在外，人气亦在外，邪气
亦在外，故宜发汗。然仲景举其略耳。设若秋冬得春夏之病，当不发汗乎？但春夏易汗而秋
冬难耳。凡发汗欲周身 然，不欲如水淋漓，欲令手足俱周遍，汗出一、二时为
佳。若汗暴出，邪气多不出，则当重发汗，则使人亡阳。凡发汗中病则止，不必尽剂。要在剂当，不
欲过也。此虽仲景调理伤寒之法，至于杂病，复何异哉？且如伤寒麻黄之类，为表实而设也
；桂枝汤之类，为表虚而设也；承气汤，为阴虚而设也；四逆汤，为阳虚而设也。表里俱实者，
所谓阳盛阴虚，下之则愈；表里俱虚者，所谓阴盛阳虚，汗之则愈也。所谓阳为表而阴为里
也，如表虚亡阳，发汗则死。发汗之法，辨阴阳，别表里，定虚实，然后汗之，随治随应。
设若飧泄不止，日夜无度，完谷下出，发汗可也。《内经》曰∶春伤于风，夏生飧泄。
此以风为根，风非汗不出。昔有人病此者，腹中雷鸣泄注，水谷不分，小便涩滞，皆曰脾胃
虚寒故耳。豆蔻、乌梅、罂粟壳、干姜、附子，曾无一效；中脘脐下，灸已数十，燥热转甚
，小溲涸竭，瘦削无
力，饮食减少。命予视之，余以谓《应象论》曰∶热气在下，水谷不分，化生飧泄；寒气
在上，则生 胀。而气不散，何也；阴静而阳动故也
。诊其两手脉息，俱浮大而长，身表微热。用桂枝麻黄汤，以姜枣煎，大剂，连进三服
，汗出终日，至旦而愈。次以胃风汤，和平脏腑，调养阴阳，食进病愈。
又贫家一男子，年二十
余，病破伤风，搐，牙关紧急，角弓反张。弃之空室，无人问者，时时呻呼。余怜其苦，以
风药投之。口噤不能下，乃从两鼻窍中灌入咽喉，约一中碗，死中求生。其药皆大黄、甘遂
、牵牛、硝石之类。良久，上涌下泄，吐且三、四升，下一、二十行，风搐立止，肢体柔和
，旦已自能起。口虽开，尚未能言。予又以桂枝麻黄汤三两，作一服，使啜之。汗出周匝如
洗，不三日而痊。
又如小儿之病，惊风搐搦，涎潮热郁，举世皆用大惊丸、抱龙丸、镇心丸
等药。间有不愈者，余潜用瓜蒂、赤小豆等分，共为细末，以猪胆汁浸蒸饼为丸，衣以螺青
或丹砂，以浆水、乳汁送之。良久，风涎涌出一两掬，三、五日一涌，涌三、五次。渐以通
圣散稍热服之，汗 然，病日已矣。
顷又治一狂人，阴不胜其阳，则脉流薄疾，
阳并乃狂。《难经》曰∶重阳者狂，重阴者癫。阳为腑，阴为脏，非阳热而阴寒也。热并于阳则狂，
狂则生寒；并于阴则癫，癫则死。《内经》曰∶足阳明胃实则狂。故登高而歌，弃衣而走，
无所不为，是热之极也。以调胃承气
，大作汤下数十行，三、五日，复上涌一、二升，三、五日又复下之，凡五、六十日，下百
余行，吐亦七、八度，如吐时，暖室置火，以助其热而汗少解，数汗方平。
又治一酒病患，
头痛、身热、恶寒，状类伤寒，诊其脉，两手俱洪大，三两日不圊。余以防风通圣散约一两，用水一中碗，
生姜二十余片，葱须根二十茎，豆豉一大撮，同煎三、五沸，去滓，稍热，分作二服，先服
一服多半，须臾以钗股探引咽中，吐出宿酒，酒之香味尚然，约一两掬，头上汗出如洗，次服
少半立愈。《内经》曰∶火郁发之。发为汗之，令其疏散也。
又尝治一税官，病风寒湿痹，
腰脚沉重，浮肿，夜则痛甚，两足恶寒，经五、六月间，犹绵胫靴足。腰膝皮肤，少有跣露，则
冷风袭之，流入经络，其痛转剧。走注上下，往来无定。其痛极处，便挛急而肿起，肉色不变，
腠理间如虫行。每遇风冷，病必转增。饮食转减，肢体瘦乏，须人扶掖，犹能行立。所服者
，乌、附、姜、桂，种种燥热；燔针着灸，莫知其数，前后三年，不获一愈。一日，命予脉
之，其两手皆沉滑有力。先以导水丸、通经散各一服，是夜泻三十余行，痛减半。遂渐服赤茯苓汤
、川芎汤、防风汤。此三方在《宣明论》中，治痹方是也。日三服，煎七、八钱，
余又作玲珑灶法熏蒸，血热病必增剧。诸汗法古方亦多有之，惟以吐发汗者，世罕知之。故余尝曰∶
吐法兼汗，良以此夫！
风、寒、暑、湿这些邪气，侵入皮肤之间但尚未深入体内，想要迅速去除它们，没有比发汗更好的方法了。圣人制定的“刺热五十九穴”（治疗热病的五十九个穴位），是为了在没有药物可用的情况下设立的，其作用都是打开玄府（汗孔）以驱逐邪气，这与发汗的原理相同。然而，不如用药物来发汗，使每一根毛发、每一个毛孔都得到启发，这样更为迅速。
然而，发汗也有几种不同的方式。世俗之人只知道只有温热性质的药才能发汗，哪里知道寒凉性质的药也能发汗呢？还有通过熏蒸浸泡来发汗的，也有通过导引（运动疗法）来发汗的。例如桂枝汤、桂枝麻黄各半汤、五积散、败毒散，这些都是发汗作用很强的温热药。例如升麻汤、葛根汤、解肌汤、逼毒散，这些都是辛温性质的药。例如大柴胡汤、小柴胡汤、柴胡饮子，这些都是苦寒性质的药。例如通圣散、双解散、当归散子，这些都是辛凉性质的药。所以，外有热象内有寒象适宜用辛温药，外有寒象内有热象适宜用辛凉药。所谓通过导引来发汗，是指华佗（字元化）创制的虎、鹿、熊、猴、鸟五种动物的模仿动作（五禽戏），使人出汗如敷粉般细密，各种疾病都能痊愈。所谓通过熏蒸浸泡来发汗，例如张苗治疗陈廪丘，烧红地面铺上桃叶让其蒸熏，大汗一出立刻痊愈。又如许胤宗治疗许太后因中风不能说话，配制了几斛防风汤，放在床下，药气如烟雾般弥漫，按照这个方法，太后随即恢复能说话的能力。这些都是前人使用过且验证有效的案例。
对照《本草》来看：荆芥、香白芷、陈皮、半夏、细辛、苍术，属于辛而温的药；蜀椒、胡椒、茱萸、大蒜，属于辛而大热的药；生姜，属于辛而微温的药；天麻、葱白，属于辛而平性的药；青皮、薄荷，属于辛苦而温的药；防己、秦艽，属于辛而且苦的药；麻黄、人参、大枣，属于甘而温的药；葛根、赤茯苓，属于甘而平性的药；桑白皮，属于甘而寒的药；防风、当归，属于甘辛而温的药；附子，属于甘辛而大热的药；官桂、桂枝，属于甘辛而大热的药；浓朴，属于苦而温的药；桔梗，属于苦而微温的药；黄芩、知母、枳实、地骨皮，属于苦而寒的药；前胡、柴胡，属于苦而微寒的药；羌活，属于苦辛而微温的药；升麻，属于苦甘且平性的药；芍药，属于酸而微寒的药；浮萍，属于辛酸而寒的药。以上这四十味药，都属于发散类的药物。
如果不善于选择，该用寒性药反而用了热性药，该用热性药反而用了寒性药，这就是病情发生变化的原因。张仲景说：“大法春夏宜汗。”春夏季节阳气在外，人气也在外，邪气也在外，所以适宜发汗。然而张仲景只是简略地提及这一点。如果秋冬季节得了春夏季节的病，难道就不发汗了吗？只是春夏季节容易发汗，而秋冬季节较难罢了。凡是发汗，希望周身微微湿润，不希望像水洗一样淋漓大汗，希望手足都均匀出汗，持续一两个时辰为佳。如果汗突然大量流出，邪气大多排不出来，反而会导致亡阳（阳气脱失）。凡是发汗，中病（达到治疗效果）就停止，不必服完所有药剂。关键在于剂量恰当，不要过量。这虽然是张仲景调理伤寒的方法，但对于杂病，又有什么不同呢？况且如伤寒中的麻黄汤之类，是为表实证设立的；桂枝汤之类，是为表虚证设立的；承气汤，是为阴虚（此处指里实热结导致阴液受损或特指阳明腑实）设立的；四逆汤，是为阳虚设立的。表里俱实的，称为阳盛阴虚，用泻下法则愈；表里俱虚的，称为阴盛阳虚，用发汗法则愈。所谓阳代表表，阴代表里，如果表虚导致亡阳，再发汗就会致死。发汗的方法，要辨别阴阳，区分表里，确定虚实，然后进行发汗，随治随应验。
假如出现飧泄（完谷不化的腹泻）不止，日夜无度，食物原样排出，此时可以发汗。《内经》说：“春伤于风，夏生飧泄。”这是因为风邪是根源，风邪非通过发汗不能排出。过去有个人患此病，腹中雷鸣般作响并剧烈腹泻，水谷不分，小便涩滞，大家都认为是脾胃虚寒所致。服用豆蔻、乌梅、罂粟壳、干姜、附子等药，毫无效果；在中脘穴和脐下艾灸数十次，燥热反而加重，小便枯竭，身体消瘦无力，饮食减少。请我诊治，我认为《应象论》中说：“热气在下，水谷不分，化生飧泄；寒气在上，则生胀满。”为什么气不散呢？因为阴主静而阳主动的缘故。诊察两手脉息，都浮大而长，体表微热。使用桂枝麻黄汤，加生姜、大枣煎煮，大剂量，连续服用三剂，整天出汗，到第二天早晨痊愈。随后服用胃风汤，调和脏腑，调养阴阳，食欲增加，病愈。
又有一位贫家男子，二十多岁，患破伤风，抽搐，牙关紧闭，角弓反张。被遗弃在空房间里，无人问津，不时呻吟。我怜悯他的痛苦，用风药投喂。他口噤无法吞咽，于是从两个鼻孔灌入咽喉，约一中碗的量，这是死中求生。那些药都是大黄、甘遂、牵牛、硝石之类的。过了很久，上涌下泄，呕吐三四升，排便一二十次，风搐立即停止，肢体变得柔和，天亮时已经能自己起身。虽然口开了，还不能说话。我又用三两桂枝麻黄汤，作为一剂，让他喝下。全身出汗如洗，不到三天就痊愈了。
又如小儿的疾病，惊风抽搐，痰涎上涌，热郁在内，举世都使用大惊丸、抱龙丸、镇心丸等药。间或有治愈不了的，我暗中用瓜蒂、赤小豆各等份，共研为细末，用猪胆汁浸透蒸饼做成丸药，外面包裹螺青或丹砂，用浆水、乳汁送服。过了很久，风涎涌出一两掬，每三、五天涌吐一次，涌吐三、五次后，逐渐改用通圣散稍加热服用，微微出汗，病日渐好转。
不久前又治疗一个狂人，阴不胜其阳，则脉流急迫快速，阳偏盛则发狂。《难经》说：“重阳者狂，重阴者癫。”阳代表腑，阴代表脏，这里并非指阳热而阴寒。热并入阳则发狂，狂躁则生寒；并入阴则发癫，癫症则危殆。《内经》说：“足阳明胃实则狂。”所以登高而歌，脱衣奔走，无所不为，这是热到了极点。使用调胃承气汤，制成汤剂服用后腹泻数十次，三、五天后，再次催吐一、二升，三、五天后又再次泻下，总共经过五、六十天，泻下一百多次，催吐七八次，在催吐时，在温暖的房间放置火盆，以助其热力从而使汗出少许得以缓解，多次发汗后才平静下来。
又治疗一个嗜酒患者，头痛、身热、恶寒，症状类似伤寒，诊察其脉，两手都洪大，三两天未排便。我用防风通圣散约一两，用水一中碗，生姜二十多片，葱须根二十茎，豆豉一大撮，同煎三、五沸，去渣，稍热，分作两次服用。先服大半剂，片刻后用钗股探引咽部，吐出宿酒，酒香味依然浓郁，约一两掬，头上出汗如洗，接着服用剩下的少量，立刻痊愈。《内经》说：“火郁发之。”发就是发汗，使其疏散。
又曾治疗一个税务官员，患风寒湿痹，腰脚沉重，浮肿，夜间疼痛加剧，两足怕冷，经过五、六个月，还穿着棉胫靴护足。腰膝皮肤稍有裸露，冷风侵袭，流入经络，疼痛更加剧烈。疼痛游走上下，往来不定。疼痛最剧烈的地方，就会痉挛肿胀，肉色不变，腠理间感觉像虫子爬行。每次遇到风冷，病情必然加重。饮食减少，肢体瘦弱乏力，需要人搀扶，还能行走站立。所服用的药物，是乌头、附子、干姜、肉桂等各种燥热之品；燔针着灸，不知有多少次，前后三年，未能痊愈。一天，让我诊脉，两手脉象都沉滑有力。先用导水丸、通经散各一剂，当晚腹泻三十多次，疼痛减半。于是逐渐服用赤茯苓汤、川芎汤、防风汤。这三个方子在《宣明论》中，是治疗痹证的方子。每天服用三次，煎煮七、八钱药量。我又制作玲珑灶法进行熏蒸，血热病必然会加剧。古代方剂中也有很多种汗法，唯独以催吐来发汗的方法，世人很少知道。所以我曾经说：吐法兼有发汗的作用，确实如此啊！
Wind, cold, summerheat, and dampness pathogenic factors enter the space between the skin but have not penetrated deeply. To eliminate them quickly, nothing is better than inducing sweating (Han Fa). The "Fifty-Nine Acupoints for Treating Heat" (Ci Re Wu Shi Jiu Ci) established by the sages were designed for situations where no medicine was available; their function is to open the Xuanku (sweat pores) to expel pathogenic factors, which is consistent with the principle of sweating. However, it is more effective to induce sweating using herbs, so that every hair follicle and pore is stimulated, making the process faster.
However, there are several methods of inducing sweating. Laypeople only know that warm and hot herbs can induce sweating, not realizing that cold and cool herbs can also do so. There are also methods involving fumigation and soaking, as well as Daoyin (qigong exercises/movement therapy). For example, Guizhi Tang (Cinnamon Twig Decoction), Guizhi Mahuang Ge Ban Tang (Half-Dose Cinnamon Twig and Ephedra Decoction), Wuji San (Five Accumulations Powder), and Baidu San (Defeat Poison Powder) are all strongly diaphoretic and warm/hot in nature. Examples like Shengma Tang (Cimicifuga Decoction), Gegen Tang (Pueraria Decoction), Ji Ji Tang (Release Muscle Decoction), and Bidu San (Force Out Poison Powder) are acrid-warm herbs. Examples such as Daxiehu Tang (Major Bupleurum Decoction), Xiaoxiehu Tang (Minor Bupleurum Decoction), and Chaihu Yinzi (Bupleurum Drink) are bitter-cold herbs. Tongsheng San (Universal Salvation Powder), Shuangjie San (Double Release Powder), and Danggui Sanzi (Angelica Powder) are acrid-cool herbs. Therefore, exterior heat with interior cold should be treated with acrid-warm herbs, while exterior cold with interior heat should be treated with acrid-cool herbs. The method referred to as "Daoyin-induced sweating" refers to the Five Animal Frolics (Wu Qin Xi) created by Hua Tuo (courtesy name Yuanhua), imitating tigers, deer, bears, monkeys, and birds, causing sweat to appear like powder, curing various diseases. The method of "fumigation-induced sweating" is exemplified by Zhang Miao treating Chen Linqiu: he heated the ground, spread peach leaves, and steamed the patient, resulting in profuse sweating and immediate recovery. Another example is Xu Yinzong treating Empress Xu, who could not speak due to wind-stroke: he prepared several hu (ancient unit of volume) of Fangfeng Tang (Saposhnikovia Decoction), placed it under the bed, allowing the medicinal vapor to fill the room like smoke; following this method, she recovered her speech. These are all cases verified by predecessors.
According to the *Bencao* (Materia Medica): Jingjie (Schizonepeta Herb), Xiang Baizhi (Angelica Dahurica Root), Chenpi (Aged Tangerine Peel), Banxia (Pinellia Tuber), Xixin (Asarum Root), and Cangzhu (Atractylodes Rhizome) are acrid and warm; Shujiao (Sichuan Pepper Fruit), Hujiao (Black Pepper Fruit), Zhuyu (Cornus Fruit), and Dasuan (Garlic Bulb) are acrid and greatly hot; Shengjiang (Fresh Ginger Rhizome) is acrid and slightly warm; Tianma (Gastrodia Rhizome) and Congbai (Scallion White) are acrid and neutral; Qingpi (Green Tangerine Peel) and Bohe (Mint Herb) are acrid-bitter and warm; Fangji (Stephania Root) and Qinjiao (Gentiana Macrophylla Root) are acrid and bitter; Mahuang (Ephedra Herb), Renshen (Ginseng Root), and Dazao (Jujube Fruit) are sweet and warm; Gegen (Kudzu Root) and Chi Fuling (Red Poria) are sweet and neutral; Sangbaipi (Mulberry Root Bark) is sweet and cold; Fangfeng (Saposhnikovia Root) and Danggui (Angelica Sinensis Root) are sweet-acrid and warm; Fuzi (Prepared Aconite Lateral Root) is sweet-acrid and greatly hot; Guanzi Gui (Cassia Bark) and Guizhi (Cinnamon Twig) are sweet-acrid and greatly hot; Houpo (Magnolia Bark) is bitter and warm; Jiegeng (Platycodon Root) is bitter and slightly warm; Huangqin (Scutellaria Root), Zhimu (Anemarrhena Rhizome), Zhishi (Immature Bitter Orange), and Digupi (Lycium Bark) are bitter and cold; Qianhu (Peucedanum Root) and Chaihu (Bupleurum Root) are bitter and slightly cold; Qianghuo (Notopterygium Rhizome) is bitter-acrid and slightly warm; Shengma (Cimicifuga Rhizome) is bitter-sweet and neutral; Shaoyao (Peony Root) is sour and slightly cold; Fuping (Duckweed) is acrid-sour and cold. All these forty herbs belong to the category of dispersing agents.
Those who are not skilled in selection may use hot herbs when cold ones are needed, or cold herbs when hot ones are needed, leading to changes in the disease pattern. Zhang Zhongjing stated: "The general rule is to induce sweating in spring and summer." In spring and summer, yang qi is on the exterior, human qi is on the exterior, and pathogenic factors are on the exterior, so inducing sweating is appropriate. However, Zhang Zhongjing only mentioned this briefly. If one contracts a spring-summer type of disease in autumn or winter, should one not induce sweating? It is merely that sweating is easier in spring/summer and harder in autumn/winter. When inducing sweating, one desires a uniform, mild moisture over the whole body, not profuse dripping sweat. One desires sweat to cover the hands and feet evenly, lasting for one or two shichen (2-4 hours) being ideal. If sweat bursts out suddenly, most pathogenic factors will not be expelled, potentially leading to Yang collapse (Wang Yang). Induce sweating until the illness is addressed (Zhong Bing), then stop; there is no need to finish the entire dose. The key is appropriate dosage, avoiding excess. Although this is Zhang Zhongjing's method for managing Shanghan (Cold Damage), how does it differ for miscellaneous diseases? For instance, Mahuang Tang (Ephedra Decoction) is for Exterior Excess patterns; Guizhi Tang (Cinnamon Twig Decoction) is for Exterior Deficiency patterns; Chengqi Tang (Gut-Purging Decoctions) are for Yin Deficiency (specifically referring to Interior Excess Heat consuming fluids); Sini Tang (Four Counterflow Decoction) is for Yang Deficiency. For patterns with both Exterior and Interior Excess, termed Yang Excess and Yin Deficiency, purgation leads to cure. For patterns with both Exterior and Interior Deficiency, termed Yin Excess and Yang Deficiency, inducing sweating leads to cure. Yang represents the Exterior, Yin represents the Interior. If Exterior Deficiency leads to Yang collapse, inducing sweating will cause death. The method of inducing sweating requires distinguishing Yin/Yang, differentiating Exterior/Interior, and determining Excess/Deficiency before applying it, ensuring immediate response.
If unsatisfactory diarrhea (Sun Xie - undigested food in stool) persists without limit day and night, with undigested food passing through, inducing sweating is permissible. The *Neijing* states: "Wind injury in spring leads to Sun Xie in summer." This is because wind is the root; wind pathogens cannot exit without sweating. Previously, a patient suffered from rumbling intestines and severe diarrhea, indistinguishable water and food, and scanty, difficult urination. Everyone attributed this to Spleen/Stomach Deficiency-Cold. Cardamom, Myrobalan, Poppy Shell, Dried Ginger, and Prepared Aconite yielded no effect. Dozens of moxibustions at Zhongwan and below the navel increased dryness and heat, dried up urine, caused emaciation and weakness, and reduced appetite. Upon consultation, I reasoned based on the *Yingxiang Lun*: "Heat Qi in the lower jiao causes indistinguishable water and food, generating Sun Xie; Cold Qi in the upper jiao generates distension." Why does the Qi not disperse? Because Yin is static and Yang is active. Palpating both wrists, the pulses were floating, large, and long; the body surface was slightly hot. I used Guizhi Mahuang Tang (Cinnamon Twig and Ephedra Decoction) decocted with ginger and jujube, in a large dose, administered three times consecutively. Profuse sweating occurred throughout the day, resolving by dawn. Subsequently, Weifeng Tang (Stomach Wind Decoction) was used to harmonize the zang-fu organs and regulate Yin/Yang, restoring appetite and curing the disease.
Another case involved a poor man in his twenties suffering from Po Shang Feng (broken skin wind/trismus), convulsions, locked jaw, and opisthotonos. Abandoned in an empty room, groaning constantly, I pitied him and administered wind-dispersing herbs. Since he could not swallow due to trismus, I instilled about one medium bowl of the medication into his throat via the nostrils, a desperate measure for survival. The herbs included Dahuang (Rhubarb Root), Gansui (Kansui Root), Qianniu (Morning Glory Seed), and Xiaoshi (Saltpeter). After some time, he vomited and purged heavily, vomiting 3-4 sheng and defecating 10-20 times. The convulsions stopped immediately, limbs softened, and he could rise by morning. Although his mouth opened, he could not speak. I then gave him 3 liang of Guizhi Mahuang Tang (Cinnamon Twig and Ephedra Decoction) as a single dose. He sweated profusely all over, recovering completely within three days.
Regarding pediatric disorders like Jing Feng (wind-stroke/convulsions) with phlegm flooding and heat stagnation, the world commonly uses Dajing Wan (Great Alarm Pill), Baolong Wan (Embrace Dragon Pill), and Zhenxin Wan (Heart-Calming Pill). For those not cured, I secretly used equal parts Genti (Melon Tip) and Chi Xiaodou (Adzuki Bean), powdered finely, formed into pills soaked in pig bile and steamed dough, coated with Luqing (Turquoise) or Dansha (Cinnabar), and delivered with Jiangshui (fermented rice liquid) or milk. After a while, 1-2 handfuls of wind-phlegm were vomited up. This was repeated every 3-5 days, 3-5 times. Gradually, Tongsheng San (Universal Salvation Powder) was taken slightly warm, inducing mild sweating, and the disease resolved daily.
Recently, I treated a madman whose Yin could not control his Yang, causing rapid, forceful pulse flow; Yang aggregation leads to mania. The *Nanjing* states: "Double Yang results in Mania, Double Yin results in Epilepsy." Yang corresponds to Fu organs, Yin to Zang organs; this refers to functional polarity, not necessarily temperature. Heat aggregating in Yang causes mania, which generates cold sensations; aggregating in Yin causes epilepsy, which is fatal. The *Neijing* states: "Fullness of Foot-Yangming Stomach leads to mania." Thus, climbing high and singing, discarding clothes and running, doing anything without restraint—this is extreme heat. I used Tiaowei Chengqi Tang (Regulate the Stomach Gut-Purging Decoction) in large decoction doses, causing dozens of bowel movements. Every 3-5 days, I induced vomiting of 1-2 sheng, followed by purgation every 3-5 days. Over 50-60 days, he purged over 100 times and vomited 7-8 times. During vomiting, a warm room with fire was used to assist heat generation, resulting in slight sweating and gradual calm after multiple sweating episodes.
I also treated a wine drinker with headache, body heat, and aversion to cold, resembling Shanghan. His pulses were both large and surging; he had not defecated for 2-3 days. I used approximately 1 liang of Fangfeng Tongsheng San (Saposhnikovia Universal Salvation Powder), decocted with one bowl of water, over 20 slices of fresh ginger, 20 scallion roots, and a large pinch of Douchi (Fermented Soybeans), boiled 3-5 times, strained, and served slightly warm in two doses. After taking more than half the first dose, I induced vomiting with a hairpin, expelling old wine (about 1 handful, still fragrant). Sweat poured from his head like washing; the remaining half dose cured him instantly. The *Neijing* states: "For Fire Stagnation, release it." "Releasing" means inducing sweating to allow dispersion.
I once treated a tax official suffering from Feng Han Shi Bi (Wind-Cold-Damp Bi syndrome), with heavy/swollen waist and legs, worse pain at night, cold aversion in both feet. For 5-6 months, he wore cotton leg guards and boots. Any exposure of skin to cold wind aggravated the pain, which moved up and down unpredictably. At the peak of pain, spasms and swelling occurred, skin color unchanged, sensation of insects crawling in the pores. Exposure to wind/cold worsened the condition. Appetite decreased, limbs became emaciated and weak, requiring support to walk. He had taken Wutou (Aconite Mother Root), Fuzi (Prepared Aconite), Jiang (Ginger), and Gui (Cinnamon)—various drying-hot substances—and undergone numerous cauterizing needle and moxibustion treatments over three years without success. Upon palpation, both pulses were deep, slippery, and forceful. First, I administered Dao Shui Wan (Water-Guiding Pill) and Tong Jing San (Meridian-Unblocking Powder), each one dose. That night, he defecated over 30 times, and pain halved. Then, gradually, he took Chi Fuling Tang (Red Poria Decoction), Chuanxiong Tang (Ligusticum Decoction), and Fangfeng Tang (Saposhnikovia Decoction). These three formulas, found in the *Xuanming Lun*, are for treating Bi syndrome. Taken three times daily, decocted with 7-8 qian of herbs. I also employed the Linglong Zao (Exquisite Stove) method for fumigation. Blood-heat conditions would inevitably worsen with heat. Ancient formulas contain many sweating methods, but few know that vomiting can induce sweating. Thus, I often said: Vomiting therapy combines with sweating effects, precisely for this reason!
