大法春宜发汗。
太阳中风，阳浮而阴弱，阳浮者自发热，阴弱者自汗出，啬啬恶寒，淅淅恶风，翕翕发热，鼻
鸣干呕者，桂枝汤主之。
桂枝 芍药 生姜（各一两半） 甘草（一两） 大枣（六个）
咀，水三升半，微火煎取一升七合半，生布绞去滓，温服一盏。须臾，啜热粥一碗，令助药
力。周覆一时，遍身 者益佳，不可令如水流漓，病必不除。若一服汗出病瘥，止后服，不必尽
剂也。若不汗，如前法更服，半日许令三服。若病重者，一日一夜可尽一剂。病证犹存者，更作服。
若汗未出，乃至二三
剂。忌生冷、粘滑、肉面、五辛、酒酪、臭恶等物。
太阳病，初服桂枝汤，反烦不解者，先刺风池、风府，却与桂枝汤则愈。按风池是少阳之经，
阳维之会，不针天柱而取风池者，阳维维诸阳，巨阳与诸阳主气故也。
庞曰∶凡桂枝汤证，病者常自汗出，小便不数，手足温和，或手足指稍露之，则微冷，覆之，
则温浑身热，微烦而又憎寒，始可行之。若病者身无汗，小便数，或手足逆冷，不恶寒，反恶热，
或饮酒后，慎不可行桂枝汤也。（脉紧必无汗，设有汗，不可误作桂枝证。）
太阳病，发汗，遂漏不止，其人恶风，小便难，四肢微急，难以屈伸者，桂枝加附子汤主之。
（桂枝汤内，加附子一枚，炮，去皮尖，切片同煎，如前。小便难，为有津液，可作汗；若小便
数，不可误认阳旦证也，阳旦即桂枝汤异名也。）
下后，脉促，胸满者，桂枝去芍药汤主之。（桂枝汤内去芍药，只用四味也。芍药味酸，脉促
胸满，恐成结胸，故去芍药之佐，全用辛甘，发散其毒瓦斯也。）
服桂枝汤，或下之，仍头项强痛，翕翕热，无汗，心下满微痛，小便不利者，桂枝去桂加白术
茯苓各一两半主之。（不用桂，加水成四升，煎取二升。）
太阳病，项背强KT KT ，汗出恶风者，桂枝加葛根二两，添水成四升，煎取二升。通治柔 。
太阳病，下之微喘者，表未解也，桂枝加杏仁浓朴汤主之。（桂枝内加浓朴一两，杏仁四十枚。）
此则中风自汗，用桂枝汤证也。
庞曰∶恶寒者，不当风而憎寒，恶风者，当风而憎寒，皆属表证。太阳病，头痛发热，身疼痛，
骨节烦疼，恶风，无汗而喘者，麻黄汤主之。
麻黄（一两半） 桂枝（一两） 甘草（半两） 杏仁（三十五个）
咀，水二升半，煮麻黄数沸，去上沫，内诸药，煮取一升二合半，去滓，每饮一盏，续次服
尽，不用粥投。温覆，如桂枝法将息，未汗，可再作二三剂。
庞曰∶伤寒之脉，紧盛而按之涩是也。脉浮而紧，浮为风，紧为寒，风伤卫，寒伤荣，荣卫俱
病，骨节烦疼。外证必发热，无汗，或喘，其人但憎寒，手足指末必微厥，久而复温，掌心不厥，
此伤寒无汗，用麻黄证。
凡脉浮数，或浮紧，无汗，小便不数，病虽十余日，尚宜麻黄汤也。
太阳中风，脉浮紧，发热恶寒，身痛，不汗出而烦躁者，大青龙汤主之。若脉微弱，自汗出，
恶风者，不可服之；服之则厥逆，筋惕肉 ，此为逆也。大青龙汤
麻黄（三两） 桂枝 甘草 石膏（各一两） 杏仁（二十个） 枣（五枚） 生姜（一两半）
咀，水五升，煮麻黄数沸，去上沫，内诸药，煮取二升。每温饮一盏，微汗为度。若汗周身
润则止服；未周身润，可停待少时服尽。不欲汗多，亡阳故也。亡阳遂虚，恶风，烦躁，不得眠也。
伤寒，脉浮缓，身不疼，但重，乍有轻时，无少阴证者，大青龙汤主之。（少阴当言太阴。按
太阴证内有脉浮缓，手足温者，系太阴。太阴当发汗，证属青龙汤；似桂枝证，反无汗而脉紧；似
麻黄证，反身不疼而脉浮缓。）
太阳病，项背KT KT ，无汗恶风，葛根汤主之。
葛根（二两） 麻黄（一两半） 桂枝（一两） 甘草（一两） 芍药（一两） 大枣（六枚）
生姜（一两半）
咀，水四升，先煮麻黄、葛根数沸，去沫，下诸药，煮取二升半，去滓。每温饮一盏，日三
服，如桂枝汤将息。
太阳与阳明合病，必自下利者，葛根汤主之。
太阳与阳明合病，不利，但呕者，葛根加半夏汤主之。用前葛根汤内加半夏一两一分，汤洗十
遍，每个作四破。
庞曰∶脉浮紧，无汗，服汤未中病。其人发烦，目瞑，极者必衄。小衄而脉尚浮者，宜麻黄汤；
衄后脉已微者，不可再行也。凡脉浮自汗，服汤不中病，桂枝证尚在，必头痛甚而致衄。小衄而脉
尚浮者，再与桂枝汤；衄后脉已微者，不可再行也。
伤寒三日后，与诸汤不差，脉势如数，阳气犹在经络，未入脏腑，宜桂枝石
膏汤。此方可夏至后代桂枝证用之；若加麻黄一两，可代麻黄、青龙汤用之。
石膏（三两） 栀子（二十四个） 生姜（一两半） 桂枝 黄芩 甘草（各一两） 升麻
葛根（各一两半）
咀，水五升，煮取二升半，去滓，温饮一盏，食顷再服。若得汗，即止后服。
庞曰∶凡发汗，以辛甘为主，复用此苦药者，何也？然辛甘者，折阴气而助阳气也。今热盛于
表，故加苦以发之。《素问》云∶热淫于内，以苦发之故也。
葛根龙胆汤疗病四五日不瘥，身体毒热，面赤，兼治阳毒风温。
葛根（生者四两，干者二两代） 生姜 升麻 大青 龙胆 桂枝 甘草 麻黄 芍药（各半两）
葳蕤（一两） 石膏（一两半）
咀，水四升半，下麻黄，煮数沸，去上沫，内诸药，煎二升，去滓。温饮一汤盏，日三夜二。
（凡葛根，须用家园味甘多白粉者为佳，若误用味苦野葛多吐，人转增病。）
时行热病，六七日未得汗，脉洪大或数，面目赤，身体大热，烦躁狂语欲走，大渴甚。又五六
日以上不解，热在胃中，口噤不能言，为坏伤寒，医所不能治。如死人，或精魂已竭，心下才暖，
发开其口，灌药下咽即活，兼治阳毒，麦奴丸。
麻黄（三分） 釜底煤 黄芩 灶底墨 梁上尘 小麦奴 灶中黄土（各一分） 芒硝 大黄
（各半两）
细末，蜜丸弹子大，新汲水三合，和一丸研服之。渴者但令冷水足意饮之，须臾当寒竟，汗出
便瘥。若日移五尺不汗，根据前法再服一丸。瘥即止，须微利。小麦奴乃小麦未熟时丛中黑麦捻之成
黑勃者是也，无，即以小麦炒黑焦，地上出火毒用之亦得。此药须是病患大渴，倍常躁盛，若小渴
者强与之为祸耳，强人每服半鸡子大。（亦治温疟。）
伤寒，连服发汗汤七八剂，汗不出者，死。如中风法蒸之，使温热之气外迎，无不得汗也，古
今用效。薪火烧地，良久去火，扫地以水洒之。取蚕沙、桃柏、荆叶、糠及麦麸皆可。同和铺烧地
上，可侧手浓，上铺席，令病患卧席上，温覆之。热月只可夹被覆，其汗立出。后周身至脚心皆汗
，乃用温粉扑止，移之上床即愈。无蚕沙即用麸糠之类，铺烧地上亦得。（温粉法，白术、
本、白芷各二两，末之，入英粉十二两，和匀用之。无英粉以 粉代之。）
伤寒瘥后，有不了了证者，谓至十日或半月二十日，终不惺惺，常昏沉以失精神，言语错谬，
或无寒热，有似鬼祟，或朝夕潮热颊赤，或有寒热如疟状，此乃发汗不尽，余毒瓦斯在心胞络间所致
也，宜知母麻黄汤。
知母（一两半） 麻黄（一两） 芍药 黄芩 甘草 桂枝（各半两）
咀，水二升半，煮麻黄数沸，去上沫，内诸药，取一升三合，去滓。每温饮一大盏，半日可
相次三服，温覆令微汗。若心烦欲水，当稍与之，令胃中和则愈。未汗尽剂。
太阳病，下之后，气上冲，其脉必浮，可根据证发汗，不与汗则成结胸也。凡发汗，脉浮大，虽
大便秘，小便少者，可发汗而解也。合汗不汗，诸毛孔闭塞，闷绝而死。
治疗的大法，春季适宜采用发汗的方法。
太阳中风证，脉象阳部（寸部）浮而阴部（尺部）弱，阳浮表示自然发热，阴弱表示自然出汗，表现为怕冷瑟瑟、怕风淅沥、发热如羽毛覆盖般温和，伴有鼻鸣和干呕的，用桂枝汤主治。
桂枝、芍药、生姜（各一两半），甘草（一两），大枣（六个）。
切碎，用水三升半，用小火煎取一升七合半，用生布过滤去除药渣，温服一盏。服药后片刻，喝热粥一碗，以助药力。周身覆盖约一小时，全身微微出汗效果更佳，不可让汗水像水流一样淋漓，否则病必不能去除。如果服用一次后出汗病愈，停止后续服药，不必服完所有药剂。如果没有出汗，按前面的方法再次服用，半天内可服三次。如果病情较重，一天一夜可以服完一剂。如果病症仍然存在，重新制作并服用。如果汗仍未出，甚至需要服用二三剂。忌食生冷、黏滑、肉类、面食、五辛、酒酪、腐臭恶秽等食物。
太阳病，初次服用桂枝汤后，反而出现烦闷不解的情况，先针刺风池穴、风府穴，然后再给予桂枝汤即可痊愈。按：风池穴是少阳经的穴位，也是阳维脉的交会穴，不针刺天柱穴而选取风池穴的原因，是因为阳维脉维系诸阳经，足太阳膀胱经与诸阳经共同主管气机运行的缘故。
庞安石说：凡是桂枝汤证，患者通常自汗出，小便次数不多，手足温暖，或者手指稍微露在外面就会感觉微冷，盖上被子则全身温热，轻微烦躁但又憎恨寒冷，这时才可以施用桂枝汤。如果患者身上无汗，小便频数，或者手足逆冷，不恶寒反而恶热，或者饮酒之后，千万不可施用桂枝汤。（脉紧必然无汗，即使有汗，也不可误认为是桂枝汤证。）
太阳病，经过发汗治疗后，导致汗漏不止，患者怕风，小便困难，四肢轻微拘急，难以屈伸的，用桂枝加附子汤主治。（在桂枝汤中加入一枚炮制过的附子，去皮尖，切片同煎，方法如前所述。小便困难，说明体内尚有津液，可以作汗；如果小便频数，不可误认为是阳旦证，阳旦即桂枝汤的异名。）
经过攻下治疗后，脉象急促，胸部胀满的，用桂枝去芍药汤主治。（在桂枝汤中去掉芍药，只保留四味药。芍药味酸，脉促胸满，恐怕会形成结胸证，所以去掉芍药的辅助作用，完全使用辛甘之品，来发散毒瓦斯。）
服用桂枝汤，或者经过攻下治疗后，仍然头项强痛，发热如羽毛覆盖般温和，无汗，心下痞满轻微疼痛，小便不利的，用桂枝去桂加白术茯苓汤主治，每味各一两半。（不用桂枝，加水至四升，煎取二升。）
太阳病，项背部僵硬不适，出汗怕风的，用桂枝加葛根汤，增加葛根二两，加水至四升，煎取二升。通用治疗柔痉证。
太阳病，经过攻下后出现轻微喘息的，表证未解，用桂枝加厚朴杏子汤主治。（在桂枝汤中加入厚朴一两，杏仁四十枚。）
庞安石说：恶寒，是不当风而感到憎恨寒冷；恶风，是当风而感到憎恨寒冷，都属于表证。太阳病，头痛发热，身体疼痛，骨节剧烈疼痛，怕风，无汗而喘息的，用麻黄汤主治。
麻黄（一两半），桂枝（一两），甘草（半两），杏仁（三十五个）。
切碎，用水二升半，先煮麻黄几沸，去掉上面的浮沫，加入其他药物，煮取一升二合半，过滤去渣，每次饮用一盏，随后依次服完，不需要喝粥送服。温覆保暖，护理方法同桂枝汤，如果未出汗，可以再制作二三剂。
庞安石说：伤寒的脉象，是紧盛且重按涩滞的。脉浮而紧，浮代表风邪，紧代表寒邪，风伤卫气，寒伤营血，营卫都生病，骨节剧烈疼痛。外证必定发热，无汗，或者喘息，患者只是憎恨寒冷，手指末端必定微厥冷，时间久了又恢复温暖，掌心不厥冷，这是伤寒无汗，适用麻黄汤的证候。
凡是脉浮数，或浮紧，无汗，小便不频数，病程虽然超过十天，仍然适宜用麻黄汤。
太阳中风，脉浮紧，发热恶寒，身体疼痛，无汗而烦躁的，用大青龙汤主治。如果脉微弱，自汗出，怕风的，不可服用；服用了就会导致四肢厥逆，筋肉跳动，这是误治。大青龙汤
麻黄（三两），桂枝、甘草、石膏（各一两），杏仁（二十个），大枣（五个），生姜（一两半）。
切碎，用水五升，先煮麻黄几沸，去掉上面的浮沫，加入其他药物，煮取二升。每次温饮一盏，以微微出汗为度。如果全身湿润就停止服药；如果全身未湿润，可以暂停片刻再服完。不希望出汗过多，因为会导致亡阳。亡阳导致虚损，会出现怕风、烦躁、无法入睡的症状。
伤寒，脉浮缓，身体不疼，只是沉重，偶尔有减轻的时候，没有少阴证的，用大青龙汤主治。（此处应为太阴证。按：太阴证内有脉浮缓，手足温暖的，属于太阴。太阴应当发汗，证候属于青龙汤；类似桂枝证，反而无汗且脉紧；类似麻黄证，反而身体不疼且脉浮缓。）
葛根（二两），麻黄（一两半），桂枝（一两），甘草（一两），芍药（一两），大枣（六枚），生姜（一两半）。
切碎，用水四升，先煮麻黄、葛根几沸，去掉浮沫，加入其他药物，煮取二升半，过滤去渣。每次温饮一盏，每日三次，护理方法同桂枝汤。
太阳与阳明合病，不下利，只是呕吐的，用葛根加半夏汤主治。在前面的葛根汤中加入半夏一两一分，用汤水洗十遍，每个半夏切成四瓣。
庞安石说：脉浮紧，无汗，服用汤药后病未愈。患者出现心烦，眼睛昏花，严重的必定流鼻血。少量鼻血后脉仍浮的，适宜用麻黄汤；鼻血后脉已微弱的，不可再行发汗。凡是脉浮自汗，服用汤药后病未愈，桂枝证仍在，必定头痛严重而导致鼻血。少量鼻血后脉仍浮的，再给予桂枝汤；鼻血后脉已微弱的，不可再行发汗。
伤寒三天后，服用各种汤药后病情未好转，脉势如数，阳气还在经络，未进入脏腑，适宜用桂枝石膏汤。此方可以在夏至后代替桂枝汤使用；如果加入麻黄一两，可以代替麻黄汤、大青龙汤使用。
石膏（三两），栀子（二十四个），生姜（一两半），桂枝、黄芩、甘草（各一两），升麻、葛根（各一两半）。
切碎，用水五升，煮取二升半，过滤去渣，温饮一盏，饭后不久再服。如果得到汗，就停止后续服药。
庞安石说：凡是发汗，以辛甘为主，又复用苦药，为什么呢？然而辛甘之品，能折降阴气而助长阳气。现在热邪盛于体表，所以加入苦味药来发散。《素问》说：热邪淫溢于内，用苦味药发散它。
葛根龙胆汤治疗患病四五日未愈，身体毒热，面红，兼治阳毒风温。
葛根（鲜者四两，干者二两代替），生姜、升麻、大青、龙胆、桂枝、甘草、麻黄、芍药（各半两），葳蕤（一两），石膏（一两半）。
切碎，用水四升半，放入麻黄，煮几沸，去掉上面的浮沫，加入其他药物，煎取二升，过滤去渣。温饮一汤盏，每日三次，夜间两次。（凡是用葛根，必须选用家园中味甘多白粉的为佳，如果误用味苦的野葛，大多会引起呕吐，使人病情加重。）
时行热病，六七日未能出汗，脉洪大或数，面目红赤，身体大热，烦躁狂语想跑动，极度口渴。又有五六日以上未解，热在胃中，口噤不能说话，这是坏伤寒，医生不能治愈。如同死人，或者精气魂魄已竭，只有心下还温暖，掰开其口，灌下药液咽下就能复活，兼治阳毒，麦奴丸。
麻黄（三分），釜底煤、黄芩、灶底墨、梁上尘、小麦奴、灶中黄土（各一分），芒硝、大黄（各半两）。
研成细末，蜂蜜制成梧桐子大小的丸药，新汲水三合，将一丸研碎服用。口渴的只让冷水随意饮用，片刻后应当感到寒冷，出汗后病愈。如果过了五尺的距离时间仍未出汗，按照前面的方法再服一丸。病愈即止，要求轻微腹泻。小麦奴是小麦未成熟时丛中黑色的麦穗搓成的黑色粉末，如果没有，就用小麦炒黑焦，除去地上的火毒使用也可以。此药必须是病患极度口渴，比平常更加躁盛，如果是小渴，强行给药反而是祸害，强壮的人每次服用半个鸡蛋大小的量。（也治疗温疟。）
伤寒，连续服用发汗汤七八剂，汗不出来的，死亡。如果用中风的方法进行熏蒸，使温热之气从外部迎接，没有不出汗的，古今使用有效。用柴火烧地，很久后去掉火，扫地并用洒水润湿。取蚕沙、桃叶、柏叶、荆叶、谷糠及麦麸都可以。混合铺在烧热的地上，厚度可侧手插入，上面铺席子，让病患躺在席子上，温热覆盖。热月只可用夹被覆盖，汗水立刻出来。之后全身直到脚心都出汗，然后用温粉扑止，移到床上就痊愈了。没有蚕沙就用麸糠之类，铺在烧热的地上也可以。（温粉法：白术、藁本、白芷各二两，研末，加入米粉十二两，混合均匀使用。没有米粉可以用粟米粉代替。）
伤寒病愈后，有遗留症状不清爽的，指到十天或半月二十天，始终不清醒，常昏沉失去精神，言语错谬，或者没有寒热，有点像鬼祟作怪，或者早晚潮热脸颊红赤，或者有寒热像疟疾的样子，这是发汗不尽，余毒瓦斯在心包络之间导致的，适宜用知母麻黄汤。
知母（一两半），麻黄（一两），芍药、黄芩、甘草、桂枝（各半两）。
切碎，用水二升半，先煮麻黄几沸，去掉上面的浮沫，加入其他药物，取一升三合，过滤去渣。每次温饮一大盏，半天内可相继服用三次，温覆令微微出汗。如果心烦想喝水，应当稍微给一点，让胃中和了就痊愈。未出汗完所有药剂。
太阳病，攻下之后，气上冲，脉象必定浮，可以根据证候发汗，如果不发汗就会形成结胸证。凡是发汗，脉浮大，虽然大便秘结，小便少的，可以发汗而解。该发汗而不发汗，诸毛孔闭塞，憋闷窒息而死。
The general principle is that in spring, it is appropriate to use diaphoresis (sweating therapy).
In Taiyang Wind Strike syndrome, the pulse is floating at the Yang position (cun) and weak at the Yin position (chi). Floating Yang indicates spontaneous fever, while weak Yin indicates spontaneous sweating. The patient presents with shivering aversion to cold, chilly aversion to wind, mild fever as if covered by feathers, nasal congestion with roaring sounds, and dry retching. Guizhi Tang (Cinnamon Twig Decoction) is the primary treatment.
Ingredients: Guizhi (Ramulus Cinnamomi), Shaoyao (Radix Paeoniae Rubra), Shengjiang (Rhizoma Zingiberis Recens) each 1.5 liang; Gancao (Radix Glycyrrhizae) 1 liang; Dazao (Fructus Jujubae) 6 pieces.
Crush the herbs, add 3.5 sheng of water, and decoct over low heat until 1.75 sheng remains. Strain through raw cloth to remove dregs. Take one zhan warm. Shortly after, drink a bowl of hot porridge to assist the medicinal power. Cover the patient for about one hour; mild sweating over the whole body is beneficial, but profuse sweating like flowing water must be avoided, otherwise the disease will not be resolved. If sweating occurs after one dose and the illness resolves, stop subsequent doses; there is no need to finish the entire prescription. If no sweating occurs, administer again according to the previous method, allowing three doses within half a day. For severe cases, one prescription may be consumed within a day and night. If symptoms persist, prepare and administer another dose. If sweating still does not occur, up to two or three prescriptions may be needed. Avoid raw/cold foods, sticky/slippery foods, meat, wheat products, the "Five Pungent Spices," wine, dairy, and foul-smelling substances.
In Taiyang disease, if the patient experiences increased irritability and unresolved symptoms after the first dose of Guizhi Tang, first puncture Fengchi (GB20) and Fengfu (GV16), then administer Guizhi Tang (Cinnamon Twig Decoction) for recovery. Note: Fengchi (GB20) belongs to the Shaoyang meridian and is a meeting point of the Yang Linking Vessel (Yangwei Mai). It is chosen over Tianzhu (BL10) because the Yang Linking Vessel connects all Yang meridians, and the Foot-Taiyang Bladder meridian governs Qi among the Yang meridians.
Pang Anshi states: In all Guizhi Tang (Cinnamon Twig Decoction) syndromes, the patient typically has spontaneous sweating, infrequent urination, and warm hands and feet. If fingers are slightly exposed, they feel mildly cold; covering them restores warmth. The body is hot, with mild irritability and aversion to cold. Only then should Guizhi Tang (Cinnamon Twig Decoction) be used. If the patient has no sweating, frequent urination, cold extremities, no aversion to cold but aversion to heat, or has recently consumed alcohol, Guizhi Tang (Cinnamon Twig Decoction) must strictly be avoided. (A tight pulse invariably indicates no sweating; even if sweating is present, it cannot be mistaken for a Guizhi Tang syndrome.)
In Taiyang disease, if excessive sweating leads to continuous leakage of sweat, aversion to wind, difficulty in urination, slight stiffness of the four limbs making flexion and extension difficult, Guizhi Jia Fuzi Tang (Guizhi Decoction with Added Aconite Root) is indicated. (Add one prepared Fuzi (Radix Aconiti Lateralis Preparata), peeled and sliced, to Guizhi Tang (Cinnamon Twig Decoction) and decoct as before. Difficulty in urination indicates sufficient body fluids for sweating; if urination is frequent, do not mistake it for Yangdan Syndrome, which is an alternative name for Guizhi Tang (Cinnamon Twig Decoction).)
After purgation, if the pulse is hurried and there is chest fullness, Guizhi Qu Shaoyao Tang (Guizhi Decoction without Paeonia) is indicated. (Remove Shaoyao (Radix Paeoniae Rubra) from Guizhi Tang (Cinnamon Twig Decoction), retaining only four ingredients. Shaoyao (Radix Paeoniae Rubra) is sour; in cases of hurried pulse and chest fullness, there is fear of forming Jie Xiong (Chest Binding); thus, the assisting role of Shaoyao (Radix Paeoniae Rubra) is removed to fully utilize pungent and sweet properties for dispersing toxic vapors.)
If, after taking Guizhi Tang (Cinnamon Twig Decoction) or undergoing purgation, the patient still suffers from stiff pain in the head and neck, mild fever, absence of sweating, fullness and mild pain in the epigastrium, and inadequate urination, Guizhi Qu Gui Jia Baizhu Fuling Tang (Guizhi Decoction without Cinnamon Twig plus Atractylodes Macrocephala and Poria) is indicated, with Baizhu (Rhizoma Atractylodis Macrocephalae) and Fuling (Sclerotium Poriae) each at 1.5 liang. (Omit Guizhi (Ramulus Cinnamomi), add water to make 4 sheng, decoct to obtain 2 sheng.)
In Taiyang disease, if there is stiffness and discomfort in the nape and back, sweating, and aversion to wind, Guizhi Jia Gegen Tang (Guizhi Decoction with Added Kudzu Root) is used, adding 2 liang of Gegen (Radix Puerariae), increasing water to 4 sheng, and decocting to 2 sheng. This treats Rou Jing (Flaccid Spasm).
In Taiyang disease, if mild wheezing occurs after purgation, the exterior syndrome is unresolved. Guizhi Jia Houpo Suxing Tang (Guizhi Decoction with Added Magnolia Bark and Apricot Seed) is indicated. (Add 1 liang of Houpo (Cortex Magnoliae Officinalis) and 40 Suiren (Semen Pruni Armeniacae) to Guizhi Tang (Cinnamon Twig Decoction).)
This describes the Wind Strike syndrome with spontaneous sweating, applicable to Guizhi Tang (Cinnamon Twig Decoction).
Pang Anshi states: "Aversion to cold" (E Han) refers to feeling chilled without exposure to wind; "aversion to wind" (E Feng) refers to feeling chilled when exposed to wind. Both belong to exterior syndromes. In Taiyang disease, with headache, fever, body pain, severe joint pain, aversion to wind, absence of sweating, and wheezing, Mahuang Tang (Ephedra Decoction) is indicated.
Ingredients: Mahuang (Herba Ephedrae) 1.5 liang; Guizhi (Ramulus Cinnamomi) 1 liang; Gancao (Radix Glycyrrhizae) 0.5 liang; Xingren (Semen Pruni Armeniacae) 35 pieces.
Crush, add 2.5 sheng of water, boil Mahuang (Herba Ephedrae) for several boils, skim off the foam, add other herbs, and decoct to 1.25 sheng. Strain. Drink one zhan warm, continuing until finished. Do not use porridge to aid absorption. Cover warmly, nursing care similar to Guizhi Tang (Cinnamon Twig Decoction). If no sweating occurs, prepare two or three more doses.
Pang Anshi states: The pulse of Shang Han (Cold Damage) is tight, vigorous, and feels choppy upon deep pressure. A floating and tight pulse: floating indicates Wind, tight indicates Cold. Wind injures Wei Qi (Defensive Qi), Cold injures Ying Blood (Nutritive Blood). When both Ying and Wei are diseased, there is severe joint pain. External signs include fever, absence of sweating, and possibly wheezing. The patient feels only aversion to cold; the fingertips are mildly cold initially but warm up later, while the palms remain warm. This is Shang Han (Cold Damage) with no sweating, indicating Mahuang Tang (Ephedra Decoction).
Whenever the pulse is floating and rapid, or floating and tight, with no sweating and infrequent urination, even if the illness has lasted over ten days, Mahuang Tang (Ephedra Decoction) is still appropriate.
In Taiyang Wind Strike, if the pulse is floating and tight, with fever, aversion to cold, body pain, absence of sweating, and irritability, Da Qing Long Tang (Major Blue Green Dragon Decoction) is indicated. If the pulse is weak and faint, with spontaneous sweating and aversion to wind, it must not be taken; doing so would lead to cold extremities and muscle twitching, which is a misdirection. Da Qing Long Tang (Major Blue Green Dragon Decoction):
Mahuang (Herba Ephedrae) 3 liang; Guizhi (Ramulus Cinnamomi), Gancao (Radix Glycyrrhizae), Shigao (Gypsum Fibrosum) each 1 liang; Xingren (Semen Pruni Armeniacae) 20 pieces; Dazao (Fructus Jujubae) 5 pieces; Shengjiang (Rhizoma Zingiberis Recens) 1.5 liang.
Crush, add 5 sheng of water, boil Mahuang (Herba Ephedrae) for several boils, skim foam, add other herbs, and decoct to 2 sheng. Drink one zhan warm; mild sweating is the goal. Stop if the whole body is moist; if not, wait a moment and finish. Do not induce excessive sweating, as this causes Wang Yang (Loss of Yang Qi). Loss of Yang Qi leads to deficiency, aversion to wind, irritability, and insomnia.
In Shang Han (Cold Damage), if the pulse is floating and slow, the body is not painful but heavy, occasionally feeling lighter, and there are no Shaoyin signs, Da Qing Long Tang (Major Blue Green Dragon Decoction) is indicated. (Note: This should refer to Taiyin Syndrome. Taiyin Syndrome includes floating-slow pulse and warm extremities. Taiyin requires diaphoresis; the syndrome fits Qing Long Tang; it resembles Guizhi Tang syndrome but has no sweating and a tight pulse; it resembles Mahuang Tang syndrome but lacks body pain and has a floating-slow pulse.)
In Taiyang disease, with stiffness in the nape and back, absence of sweating, and aversion to wind, Gegen Tang (Kudzu Decoction) is indicated.
Ingredients: Gegen (Radix Puerariae) 2 liang; Mahuang (Herba Ephedrae) 1.5 liang; Guizhi (Ramulus Cinnamomi) 1 liang; Gancao (Radix Glycyrrhizae) 1 liang; Shaoyao (Radix Paeoniae Rubra) 1 liang; Dazao (Fructus Jujubae) 6 pieces; Shengjiang (Rhizoma Zingiberis Recens) 1.5 liang.
Crush, add 4 sheng of water, first boil Mahuang (Herba Ephedrae) and Gegen (Radix Puerariae) for several boils, skim foam, add other herbs, and decoct to 2.5 sheng. Strain. Drink one zhan warm, three times daily, nursing care as with Guizhi Tang (Cinnamon Twig Decoction).
In combined Taiyang and Yangming disease with spontaneous diarrhea, Gegen Tang (Kudzu Decoction) is indicated.
In combined Taiyang and Yangming disease without diarrhea but with vomiting, Gegen Jia Banxia Tang (Kudzu Decoction with Added Pinellia) is indicated. Add 1.1 liang of Banxia (Rhizoma Pinelliae) to the previous Gegen Tang (Kudzu Decoction), wash ten times with decoction, and cut each piece into four.
Pang Anshi states: With a floating-tight pulse and no sweating, if the decoction fails to resolve the disease, the patient becomes irritable and eyes dim; severely, epistaxis (nosebleed) occurs. If slight epistaxis occurs and the pulse remains floating, Mahuang Tang (Ephedra Decoction) is suitable; if the pulse becomes faint after epistaxis, do not re-administer. In cases of floating pulse with spontaneous sweating, if the decoction fails and Guizhi Tang (Cinnamon Twig Decoction) syndrome persists, severe headache leading to epistaxis occurs. If slight epistaxis occurs and the pulse remains floating, re-administer Guizhi Tang (Cinnamon Twig Decoction); if the pulse becomes faint after epistaxis, do not re-administer.
Three days after Shang Han (Cold Damage), if various decoctions fail to improve the condition, and the pulse rate increases, with Yang Qi still in the meridians and not yet in the viscera, Guizhi Shigao Tang (Guizhi Decoction with Gypsum) is indicated. This formula can replace Guizhi Tang (Cinnamon Twig Decoction) after the Summer Solstice; if 1 liang of Mahuang (Herba Ephedrae) is added, it can replace Mahuang Tang (Ephedra Decoction) and Da Qing Long Tang (Major Blue Green Dragon Decoction).
Ingredients: Shigao (Gypsum Fibrosum) 3 liang; Zhizi (Fructus Gardeniae) 24 pieces; Shengjiang (Rhizoma Zingiberis Recens) 1.5 liang; Guizhi (Ramulus Cinnamomi), Huangqin (Radix Scutellariae), Gancao (Radix Glycyrrhizae) each 1 liang; Shengma (Rhizoma Cimicifugae), Gegen (Radix Puerariae) each 1.5 liang.
Crush, add 5 sheng of water, decoct to 2.5 sheng, strain. Drink one zhan warm, repeat shortly after eating. If sweating occurs, stop subsequent doses.
Pang Anshi states: Diaphoresis primarily uses pungent and sweet herbs. Why add bitter herbs? Pungent and sweet herbs reduce Yin Qi and assist Yang Qi. Since heat is abundant on the exterior, bitter herbs are added to disperse it. The *Su Wen* states: "When heat floods internally, disperse it with bitter herbs."
Gegen Longdan Tang (Kudzu and Gentian Decoction) treats illnesses lasting four to five days without resolution, characterized by toxic heat in the body and red face. It also treats Yang Du (Yang Toxin) and Feng Wen (Wind Warmth).
Ingredients: Gegen (Radix Puerariae) 4 liang fresh (or 2 liang dried); Shengjiang (Rhizoma Zingiberis Recens), Shengma (Rhizoma Cimicifugae), Daqing (Folium Isatidis), Longdan (Radix Gentianae), Guizhi (Ramulus Cinnamomi), Gancao (Radix Glycyrrhizae), Mahuang (Herba Ephedrae), Shaoyao (Radix Paeoniae Rubra) each 0.5 liang; Weirui (Rhizoma Polygonati Odorati) 1 liang; Shigao (Gypsum Fibrosum) 1.5 liang.
Crush, add 4.5 sheng of water, add Mahuang (Herba Ephedrae), boil briefly, skim foam, add other herbs, decoct to 2 sheng, strain. Drink one zhan warm, three times daily and twice nightly. (For Gegen (Radix Puerariae), choose garden-grown varieties with sweet taste and high starch content. Mistakingly using bitter wild Ge Gen often causes vomiting and worsens the condition.)
In epidemic febrile diseases, if six to seven days pass without sweating, with a surging or rapid pulse, red face and eyes, high body heat, irritability, delirious speech, restlessness, and extreme thirst, or if unresolved after five to six days with heat in the Stomach, locked jaw, and inability to speak, this is Huai Shang Han (Damaged Cold Damage), incurable by physicians. If the patient appears dead or spirit is exhausted but the epigastrium is still warm, open the mouth, pour medicine down, and life may be restored. This also treats Yang Du (Yang Toxin) and Maitu Wan (Wheat Slave Pill).
Ingredients: Mahuang (Herba Ephedrae) 3 fen; Fudi Mei (Carbon from Pot Bottom), Huangqin (Radix Scutellariae), Zaodi Mo (Carbon from Hearth Bottom), Liangshang Chen (Dust from Beam), Xiaomai Nu (Wheat Slave), Zaohuang Tu (Yellow Earth from Hearth) each 1 fen; Mangxiao (Natrii Sulfas), Dahuang (Radix et Rhizoma Rhei) each 0.5 liang.
Grind to fine powder, form pills the size of mustard seeds with honey. Dissolve one pill in 3 he of fresh well water and take. For thirst, allow free drinking of cold water. Soon, chills will occur, followed by sweating and recovery. If no sweating occurs after the time it takes to walk five chi, administer another pill per previous method. Stop when recovered; mild diarrhea is expected. Xiaomai Nu (Wheat Slave) is the black powder formed by rubbing unripe black wheat spikes; if unavailable, stir-fry wheat until blackened, remove fire toxicity, and use. This medicine is for patients with extreme thirst and intense restlessness; forcing it on those with mild thirst is harmful. Strong individuals take half an egg-sized pill. (Also treats Wen Nue [Warm Malaria].)
In Shang Han (Cold Damage), if seven or eight doses of diaphoretic decoctions are taken without sweating, death ensues. Use the Wind Strike method of steaming: create external warm air to induce sweating, which has been effective throughout history. Burn firewood on the floor, let it burn for a long time, remove fire, sweep the floor, and sprinkle with water. Use Can Sha (Silkworm Excrement), Tao Ye (Peach Leaves), Bai Ye (Cypress Leaves), Jing Ye (Vitex Leaves), Bran, and Wheat Chaff. Mix and spread on the heated floor, thickness allowing hand insertion. Place a mat on top, have the patient lie on it, and cover warmly. In hot months, use a quilt. Sweating will emerge immediately. Once sweating reaches the soles of the feet, apply Wen Fen (Warm Powder) to stop sweating, then move the patient to bed for recovery. If Can Sha (Silkworm Excrement) is unavailable, bran/chaff suffices. (Wen Fen Recipe: Baizhu (Rhizoma Atractylodis Macrocephalae), Ben Cao (Radix Ligustici Chuanxiong), Baizhi (Radix Angelicae Dahuricae) each 2 liang, powdered, mixed with 12 liang of rice flour. Substitute millet flour if rice flour is unavailable.)
After recovery from Shang Han (Cold Damage), lingering unclear symptoms may persist for ten days to twenty days, with constant mental fog, loss of spirit, erroneous speech, or no chills/fever resembling ghost possession, or morning/evening tidal fever with red cheeks, or chills/fever resembling malaria. This is caused by incomplete diaphoresis leaving residual toxic vapors in the Pericardium Collateral. Zhimu Mahuang Tang (Anemarrhena and Ephedra Decoction) is indicated.
Ingredients: Zhimu (Rhizoma Anemarrhenae) 1.5 liang; Mahuang (Herba Ephedrae) 1 liang; Shaoyao (Radix Paeoniae Rubra), Huangqin (Radix Scutellariae), Gancao (Radix Glycyrrhizae), Guizhi (Ramulus Cinnamomi) each 0.5 liang.
Crush, add 2.5 sheng of water, boil Mahuang (Herba Ephedrae) briefly, skim foam, add other herbs, decoct to 1.3 sheng, strain. Drink one large zhan warm, three doses consecutively within half a day, cover warmly for mild sweating. If irritable and thirsty, give small amounts of water until the Stomach harmonizes and recovery occurs. Finish the prescription if no sweating occurs.
In Taiyang disease, after purgation, if Qi rushes upward and the pulse is floating, diaphoresis may be administered according to the syndrome. Failure to sweat will result in Jie Xiong (Chest Binding). Generally, if the pulse is floating and large, even with constipation and scant urine, diaphoresis can resolve the disease. Failure to sweat when indicated leads to closure of all pores, suffocation, and death.
