陆肖愚治徐邑宰，秋末冬初遍身生疖，大小不一，红痛 痒，黄水淋漓。或谓风热，用防风通圣，
数剂不减。或谓诸痛疮疡，皆属心火，用芩、连、山栀、生地等，十剂益甚，且饮食渐减。脉之，浮
按微数，沉按中
按皆缓而弱。曰∶凡风热，大都为瘾疹，未必为疮疖，至疮疡之为心火，经固言之，第脉微弱为多，
此元气不足也。缓者，湿也。数虽为热，而微数不可纯责之火。据今日之症，火为标，湿为本。原得
病之由，又湿为标，元气不足为本。此必乘虚汗出澡浴，湿渍肉腠，久而热蚀为脓水，发为痛痒也。
用苍术、薏仁、茯苓燥湿为君，人参、白术、黄 、甘草补气为臣，连翘、蝉蜕清热为佐，葛根、白
芷入阳明肌肉为使。二剂，痛痒顿减，胃少开，十剂全愈。
张子和治颖皋韩吉卿，自髀至足，生湿 ，大者如钱，小者如豆，痒则搔破，水到则浸淫，类虫
行袜，愈而复生，瘢痕成凹，十余年不瘥。张哂之曰∶此湿 疮也，由水湿而得，故多在足下。以
舟车、济川，大下十余行，一去如扫。
一省掾背项常有痤疖，愈而复生。张曰∶太阳血有余也。先令涌泄之，次于委中 针出紫血，病
更不复作也。张君衮常，喜热火烘灼其背及两足，又食自死肉，久而两足常生疖毒，愈而复生半月余。
以清凉饮子下之，得紫黑血积于便中，去者月余，其积毒顿除，是知积热毒致痈肿者如此。
薛立斋治春元沈霓川之内，暑月面生痤疖，乘凉入风，面目浮肿。 二日，左臂肿痛，瘾疹如丹，
背胁髀股等处，发肿块三四，肉色不红，痛甚，昼夜号呼，寒热往来，饮食不思。服活命饮及行气败
毒之剂，其势愈炽。肝脉浮涩，脾脉弦弱，此属二经荣气不从，风邪乘虚流注经络为患。先以八珍加
黄、柴胡、青皮，数处渐渐红 。又以十全大补加银花、白芷、龙胆草、贝母，十余剂，胁腿二处
溃脓碗许，余块渐平。仍服十全大补汤，调理月余而安。向使专于祛风攻毒，鲜不败事矣。
张仲安治冻疮，用黄柏烧存性，研细，以鸡子清调敷。破者，干糁上，神妙。
治暑月肌肤疮烂，或因搔成疮，多是大暑汗出，坐卧湿地，致肌肤多疮烂汁出。有一乳母曰∶此
易瘥也。取干壁细土末敷之，随手即瘥。
治一切恶疮，遍用药不效者，陈米饭紧作团，火 存性，麻油、腻粉调敷。苏滔光丁亥年，耳上
病碎疮，
或痛或痒两月余，百药不效。季 子长传此方，初不之信，试用之，果日即愈。辛丑年再作，吕仲发
显谟云∶此症夏以痰饮法治之。故只用肥皂烧存性，生油、腻粉调敷尤佳。
薛立斋治一男子，年四十三岁。自四十以来，每至夏，发热而倦，日午益甚，晚凉少可，面生疮
，耳下筋微肿，更结小核三四枚，附筋上。曰∶此火令不慎房劳，亏损肾水，不能制火然也，名曰
注夏。彼不信，服降火败毒药，加口干倦怠，夜间热甚，午后腿软，足心热，筋牵痛，复来问治。曰∶
口干倦怠，此中气陷下也；夜间发热，阳气陷于阴分也；午后腿软足热，阴虚火甚也；耳下筋牵痛，
血虚不能润筋也。先以补中益气汤，少用柴胡、升麻，加五味、麦冬、熟地治之，诸症顿退。更服滋
肾丸而痊。若以每至火令而然，用败毒凉药，鲜不危矣。凡春末夏初，患头痛脚软，食少体热，此仲
景云春夏剧，秋冬瘥，而脉弦大者，正世俗所谓注夏病也。
赵州守北方人，年逾四十，头面生疮疡数枚， 痛饮冷，积日不溃，服清热消毒药不应。诊其脉
数，按之则实，以防风通圣散，二剂顿退，又以荆防败毒散而愈。又一男子，患在四肢，审其脉症，
亦属有余，以黄连解毒汤治之亦愈。
缪仲淳治一妇人，生疖臂上，用连翘、白芷、白芨、花粉各二钱，甘菊一两，紫花地丁、金银花
各五钱，甘草、生地、茜草各三钱，地榆四钱，角刺、牛蒡各一钱，服之半日，立出脓血而愈。又治
一男子，生疖膝下，加牛膝三钱，立破出鲜血愈。（《广笔记》）
丁右武亲验坐板疮方，松香五钱，雄黄一钱，均研细。如湿痒，加苍术三钱。各末和匀，以绵纸
包里，捻成纸燃二条，腊月猪油浸透，点火烧着，取滴下油，搽上立效。（同上。）
立斋治一男子，年逾四十，胃气素弱，面常生疮，盗汗发热，用黄 建中汤，少愈。更以补中益
气汤而平。东垣云∶气虚则腠理不密，邪气从之，逆于肉里，故多生疮。若以甘温之剂，实其根本，
则腠理自固，即无他疾。
张生患漆疮作呕，由中气弱，漆毒侵之。以六君子汤加砂仁、藿香、酒芍治之。彼不信，另服连
翘消毒散，呕果盛。复求治，仍以前药，外以麻油调铁锈末涂之而愈。
赵千兵患两腿生疮，每服败毒药，则饮食无味，反增肿胀，此脾虚湿热下注也。以六君子汤加苍
术、升麻、酒芍服之，以黄蜡、麻油各一两，轻粉三钱，为膏贴之而愈。大凡下部生疮，虽属湿热，
未有不因脾肾虚而得者。
一男子湿热下注，两腿生疮，以人参败毒散，加苍术、黄柏服之，以金黄散敷贴。又一人患此，
久而不愈，以船板灰存性一两，轻粉三钱，为散，麻油调敷。更以黄柏、知母、防己、龙胆草、茯苓、
当归、川芎、黄 、白术，服之亦愈。若人两腿作痛，或遍身作痛，以当归拈痛汤治之。
一妇人两腿腕紫黯寸许，搔破出水。或用祛风砭血之剂，年余渐平如掌。乃服草乌等剂，遍身搔
痒，有时出血水，内热体倦，饮食无味，月经三月一至，脉洪而数，按之则涩，此燥剂愈伤脾血也。
先以补中益气汤加白芍、川芎、五味，十余剂，乃与加味逍遥散加熟地、钩藤，二十余剂，再用归脾
汤加川芎、熟地，治之而不发。
一妇人素清苦，四肢似癣疥，作痒出水，怒则起赤晕。服祛风败毒等剂，赤晕成疮，脓水淋漓，
晡热内热，自汗盗汗，月经不行，口干，咽喉肿痛，此郁伤脾血也。用归脾汤、逍遥散，两月而痊。
一儒者素食膏粱，发热，作渴饮冷，患疮如大麻风，大便出黑血，服清热祛风等寒药益甚。谓血
分有热火也，故寒之不寒。用四物二连汤以清热凉血，用六味丸以补肾生水而热退。又用柴胡栀子散，
调理而痊。
一妇人性急善怒，月经不调，内热口苦，患时疮，服败毒药，脓水淋漓，热渴头痛，日晡益甚。
用加味逍遥散，服之渐愈。因大怒，月经如涌，眼赤出泪，用四物汤加山栀、柴胡、芩、连，数剂而
愈。年余，手足臂腕起白点，渐大，搔起白屑，内热盗汗，月经两月余一至。忽怒，或恶寒头痛，或
胸乳作胀，或腹内作痛，或小便见血，或小水不利，或白带下注。此皆肝木制伏脾土，元气虚而变症
也。用补中益气汤加黑山栀，及加味归脾汤间服，半年而愈。
一妇人久郁，患在四肢，腿腕尤甚。误用败毒寒凉之剂，晡热内热，自汗盗汗，月经不行，口干
咽燥，此
郁火伤脾也。用归脾汤数剂，后兼服逍遥散，五十余剂而痊。
刘松篁经验方云∶会水湾陈玉田妻，患天蛇毒疮。一老翁用水蛇一条，去头尾，取中截，如手足
指长，刮去骨肉，勿令病者见，以蛇皮包手指，自然束紧，以纸外裹之，顿觉遍身皆凉，其病即愈。
数日后解视，手指有一沟如小蝇，蛇皮内宛然有一小蛇，头目俱全也。（《本草纲目》）
孙思邈以贞观五年七月十五日夜，以左手中指触着庭木，至晓，遂患痛不可忍。经十日，痛日深，
疮日高硕，色如熟小豆色。尝闻长者论有此方，遂用治之，手下即愈，痛亦除，疮亦即瘥，未十日而
复如故。方用蒲公英捣烂取汁，涂之愈。（同上。）
张子和曰∶麻先生妻，病足趾痛不可忍，酒调通经散一钱半，夜先吐，吐毕而痛减。余因叹曰∶
向见陈五曾病此，医以为小虫伤，或以草上有毒物触之，迁延数月，脓尽方已。今日观方，可发大笑。
王思中治一人，患疮疹，阴囊肿胀如斗升，不能跬步。王曰∶此疮蛊也。就外科剂中加麦秆四十
九茎遂消。（《吴江县志》）
戊申之水，乃二百余年创见之变，人足浸水中，数日即皮破生疮，痛不可忍。一法取水荆条煎水
浴之立愈。（《续金陵琐事》）
梁溪一男子，生疖膝下，楚甚。仲淳适至，即于席间作剂服之，饮酒数杯，疖立破，出鲜血愈。
连翘三钱，白芷二钱，粉甘草水炙三钱，金银花五钱，牛膝三钱，生地三钱，地榆四钱，皂刺一钱，
鼠粘子酒炒研一钱。
陆肖愚治疗徐邑宰，在秋末冬初时节，患者全身生出疖子，大小不一，红肿疼痛且瘙痒，流出黄色脓水。有人认为是风热所致，使用防风通圣散，服用数剂后病情未见减轻。有人依据“诸痛疮疡，皆属心火”的理论，使用黄芩、黄连、山栀、生地等药物，服用十剂后病情反而加重，且饮食逐渐减少。诊脉时，轻取（浮按）脉象微数，重取（沉按）及中取脉象皆缓而弱。陆肖愚说：“凡是风热之证，大多表现为瘾疹（荨麻疹类皮肤病），未必是疮疖；至于疮疡属于心火的说法，医经中确实有记载，但通常脉象微弱居多，此患者是元气不足的表现。脉缓代表湿邪。脉数虽然主热，但微数之脉不能单纯归咎于火毒。根据今日的症状，火毒是标，湿邪是本。追溯病因，湿邪是标，元气不足是本。这一定是因为乘虚出汗后洗澡，湿气浸渍肌肉腠理，日久热毒侵蚀化为脓水，从而引发疼痛和瘙痒。”于是用苍术、薏仁、茯苓作为君药以燥湿，人参、白术、黄芪、甘草作为臣药以补气，连翘、蝉蜕作为佐药以清热，葛根、白芷作为使药入阳明经肌肉层。服用两剂后，疼痛和瘙痒顿时减轻，胃口稍开，服用十剂后完全痊愈。
张子和治疗颖皋人韩吉卿，从大腿到脚部生出湿疮，大的如铜钱，小的如豆粒，瘙痒时抓破，水流出来则浸淫扩散，像虫子在袜子里爬行一样，好了又生，留下凹陷的瘢痕，十多年不愈。张子和嘲笑他说：“这是湿疮，由水湿引起，所以多长在足下。”于是用舟车丸、济川煎等大泻之剂，令患者腹泻十余次，病去如扫。
一位省掾官背部和颈部常有痤疮疖肿，好了又生。张子和说：“这是太阳经血有余。”先让他用涌吐法泄邪，随后在委中穴针刺放出紫黑色血液，病症便不再发作。张君衮常，喜欢用火烘烤背部和双脚，又吃自死的肉，久而久之双脚经常生疖毒，好了又生，持续半个月以上。用清凉饮子攻下，排出积存在大便中的紫黑色瘀血，病去月余，积毒顿除，由此可知积热毒导致痈肿的情况就是这样。
薛立斋治疗秀才沈霓川的妻子，在暑天面部生出痤疮疖肿，因乘凉受风，导致面目浮肿。两天后，左臂肿痛，出现丹痧样瘾疹，背部、胁肋、大腿、股部等处，发出三四块肿块，肤色不红，疼痛剧烈，昼夜呼号，寒热往来，不思饮食。服用活命饮及行气败毒的药物，病情反而更加炽盛。诊得肝脉浮涩，脾脉弦弱，这属于这两条经络的营气运行不畅，风邪乘虚流注经络为患。先用八珍汤加黄芪、柴胡、青皮，几处肿块渐渐变红。接着用十全大补汤加金银花、白芷、龙胆草、贝母，服用十余剂后，胁部和腿部两处溃烂出脓约一碗许，其余肿块渐渐平复。仍然服用十全大补汤调理月余而安定。假如专门采用祛风攻毒的方法，很少有不失败的。
张仲安治疗冻疮，用黄柏烧至存性，研成细粉，用鸡蛋清调和敷贴。皮肤破损者，直接干撒药粉，效果神妙。
治疗暑天肌肤疮烂，或因搔抓形成的疮口，大多是大暑天出汗时，坐卧湿地，导致肌肤多处疮烂流水。有一位乳母说：“这很容易治愈。”取干燥的墙壁细土末敷在上面，随手即愈。
治疗一切恶疮，遍用药都不见效的，用陈米饭紧紧搓成团，火烤至存性，用麻油、腻粉调和敷贴。苏滔光在丁亥年，耳上生出碎疮，或痛或痒两个多月，百药无效。季长传了这个方子，起初不信，试用后，果然日渐痊愈。辛丑年复发，吕显谟说：“这个症状夏天应该用治痰饮的方法处理。”所以只用肥皂烧至存性，用生油、腻粉调和敷贴尤其好。
薛立斋治疗一名男子，四十三岁。从四十岁以来，每到夏天就发热疲倦，中午时分加重，傍晚凉爽时稍好，面部生疮，耳下筋脉微肿，又结出三四枚小核，附着在筋上。薛立斋说：“这是因为在火令（夏季）不慎房事，亏损肾水，不能制约心火所致，名叫‘注夏’。”患者不信，服用降火败毒的药物，加上口干倦怠，夜间发热严重，午后腿软，足心热，筋脉牵拉疼痛，再次来求治。薛立斋说：“口干倦怠，这是中气下陷；夜间发热，是阳气陷入阴分；午后腿软足热，是阴虚火旺；耳下筋脉牵拉疼痛，是血虚不能濡养筋脉。”先用补中益气汤，少用柴胡、升麻，加五味子、麦冬、熟地黄治疗，各种症状顿时消退。再服用滋肾丸而痊愈。如果认为每到火令就发病，用败毒凉药，很少有不出危险的。凡是春末夏初，患头痛脚软，食少体热，脉象弦大的，正是张仲景所说的“春夏剧，秋冬瘥”，也就是世俗所谓的注夏病。
赵州守是北方人，年过四十，头面生出数个疮疡，喜冷饮，多日不溃破，服用清热消毒药无效。诊其脉数，重按则实，用防风通圣散，两剂后症状顿退，又以荆防败毒散而愈。又一男子，患病在四肢，审察其脉症，也属实证，用黄连解毒汤治疗也痊愈了。
缪仲淳治疗一名妇人，手臂上生疖，用连翘、白芷、白芨、花粉各二钱，甘菊一两，紫花地丁、金银花各五钱，甘草、生地、茜草各三钱，地榆四钱，皂角刺、牛蒡子各一钱，服用半天后，立刻出脓血而愈。又治疗一名男子，膝下生疖，加牛膝三钱，立刻破溃出鲜血而愈。（《广笔记》）
丁右武亲验的坐板疮方：松香五钱，雄黄一钱，均研细。如果是湿痒，加苍术三钱。将各药末和匀，用绵纸包起来，捻成两条纸捻，腊月猪油浸透，点火燃烧，收集滴下的油，搽在患处立即见效。（同上。）
薛立斋治疗一名男子，年过四十，胃气素来虚弱，面部经常生疮，盗汗发热，用黄芪建中汤，稍见好转。再用补中益气汤而平复。李东垣说：“气虚则腠理不密，邪气随之侵入，逆乱于肌肉纹理之间，所以多生疮疡。如果用甘温的药剂，充实根本，那么腠理自然坚固，就没有其他疾病了。”
张生患漆疮并呕吐，是因为中气弱，漆毒侵袭。用六君子汤加砂仁、藿香、酒白芍治疗。他不信，另服连翘消毒散，呕吐果然加重。再次求治，仍用前药，外用麻油调铁锈末涂敷而愈。
赵千兵患双腿生疮，每次服用败毒药，则饮食无味，反而增加肿胀，这是脾虚湿热下注所致。用六君子汤加苍术、升麻、酒白芍服用，用黄蜡、麻油各一两，轻粉三钱，制成膏药贴敷而愈。大凡下部生疮，虽属湿热，没有不是因为脾肾虚而得的。
一男子湿热下注，双腿生疮，用人参败毒散，加苍术、黄柏服用，外敷金黄散。另一人患此病，久不愈合，用船板灰存性一两，轻粉三钱，制成散剂，麻油调和敷贴。再用黄柏、知母、防己、龙胆草、茯苓、当归、川芎、黄芪、白术内服，也痊愈了。如果人双腿疼痛，或遍身疼痛，用当归拈痛汤治疗。
一妇人两脚踝部紫暗一寸左右，抓破出水。或用祛风砭血的药剂，一年多渐渐平复如手掌大小。后来服用草乌等药剂，遍身瘙痒，有时出血水，内热体倦，饮食无味，月经三个月来一次，脉洪大而数，重按则涩，这是燥剂进一步损伤脾血所致。先用补中益气汤加白芍、川芎、五味子，十余剂，然后给予加味逍遥散加熟地、钩藤，二十余剂，再用归脾汤加川芎、熟地黄治疗，病不再发。
一妇人向来清苦，四肢似癣疥，作痒出水，发怒时出现赤色晕圈。服用祛风败毒等药剂，赤晕变成疮，脓水淋漓，下午发热内热，自汗盗汗，月经不行，口干，咽喉肿痛，这是郁结损伤脾血所致。用归脾汤、逍遥散，两个月而痊愈。
一儒者平时食用肥甘厚味，发热，口渴想喝冷水，患疮如同大麻风，大便排出黑血，服用清热祛风等寒凉药物反而加重。说是血分有热火，所以用寒药不能清热。用四物二连汤以清热凉血，用六味丸以补肾生水从而使热退。又用柴胡栀子散，调理而痊愈。
一妇人性急易怒，月经不调，内热口苦，患时疮，服用败毒药，脓水淋漓，热渴头痛，下午时分加重。用加味逍遥散，服用后渐渐痊愈。因大怒，月经如涌，眼赤流泪，用四物汤加山栀、柴胡、黄芩、黄连，数剂而愈。一年多后，手足臂腕起白点，渐渐变大，抓挠起白屑，内热盗汗，月经两个多月来一次。忽而发怒，或恶寒头痛，或胸乳作胀，或腹内作痛，或小便见血，或小水不利，或白带下注。这都是肝木克制脾土，元气虚弱而变生的症状。用补中益气汤加黑山栀，以及加味归脾汤交替服用，半年而愈。
一妇人长期郁结，患病在四肢，脚踝尤甚。误用败毒寒凉的药剂，下午发热内热，自汗盗汗，月经不行，口干咽燥，这是郁火伤脾所致。用归脾汤数剂，后来兼服逍遥散，五十余剂而痊愈。
刘松篁的经验方说：会水湾陈玉田的妻子，患天蛇毒疮。一位老翁用水蛇一条，去掉头尾，取中间一段，长度如手指，刮去骨肉，不让病人看见，用蛇皮包裹手指，自然束紧，外面用纸裹住，顿时觉得全身凉爽，病即痊愈。几天后解开查看，手指有一沟槽如小苍蝇，蛇皮内宛然有一条小蛇，头目俱全。（《本草纲目》）
孙思邈在贞观五年七月十五日夜，用左手中指触到庭院树木，到天亮，突然患痛不可忍。经过十天，疼痛日益加深，疮疡日益高肿，颜色如熟小豆色。曾听长者论述有此方，于是用它治疗，手下即愈，痛亦消除，疮亦即好，不到十天又恢复原状。方用蒲公英捣烂取汁，涂敷而愈。（同上。）
张子和说：麻先生的妻子，病足趾痛不可忍，用酒调服通经散一钱半，夜里先呕吐，吐完而痛减。我因而感叹道：先前见陈五曾患此病，医生认为是小虫咬伤，或是被草上有毒之物触碰，拖延数月，脓尽才停止。今天看这个方子，可让人大笑。
王思中治疗一人，患疮疹，阴囊肿胀如斗升，不能迈步。王医生说：“这是疮蛊。”就在外科药剂中加入麦秆四十九茎，随即消散。（《吴江县志》）
戊申年的大水，是二百多年来罕见的变故，人脚浸泡在水中，数日后皮肤破裂生疮，痛不可忍。一种方法是取水荆条煎水沐浴，立即痊愈。（《续金陵琐事》）
梁溪一男子，膝下生疖，非常痛苦。缪仲淳恰好来到，即在席间配制药剂让他服用，饮酒数杯，疖子立刻破溃，出鲜血而愈。处方：连翘三钱，白芷二钱，粉甘草水炙三钱，金银花五钱，牛膝三钱，生地三钱，地榆四钱，皂角刺一钱，鼠粘子（牛蒡子）酒炒研一钱。
Lu Xiaoyu treated the magistrate of Xu County. At the end of autumn and beginning of winter, the patient developed boils all over his body, varying in size, with redness, pain, itching, and profuse yellow discharge. Some attributed it to wind-heat and prescribed Fangfeng Tongsheng San (Windproof Unblocking Hero Decoction), but after several doses, there was no improvement. Others, citing the principle that "all painful sores and ulcers belong to heart fire," prescribed herbs such as Huangqin (Scutellariae Radix), Lianlian (Coptidis Rhizoma), Shanzhi (Gardeniae Fructus), and Shengdi (Rehmanniae Radix). After ten doses, the condition worsened, and appetite gradually decreased. The pulse was slightly rapid on superficial palpation (floating) and slow and weak on deep and moderate palpation. Lu said: "Generally, wind-heat manifests mostly as urticaria (wind rash), not necessarily as boils or sores. Although classics state that sores can belong to heart fire, the pulse is usually weak and faint, indicating deficiency of primordial qi. A slow pulse indicates dampness. Although a rapid pulse indicates heat, a slightly rapid pulse cannot be solely blamed on fire toxin. Based on today's symptoms, fire toxin is the branch (manifestation), and dampness is the root (cause). Tracing the etiology, dampness is the branch, and deficiency of primordial qi is the root. This must have occurred because he bathed while sweating due to deficiency, allowing dampness to soak into the muscle and interstices. Over time, heat eroded the tissue, turning it into pus and water, causing pain and itching." He used Cangzhu (Atractylodis Rhizoma), Yiren (Coicis Semen), and Fuling (Poria) as sovereign herbs to dry dampness; Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Huangqi (Astragali Radix), and Gancao (Glycyrrhizae Radix) as minister herbs to tonify qi; Liaoqiao (Forsythiae Fructus) and Chantui (Cicadae Periostracum) as assistant herbs to clear heat; and Gegen (Puerariae Lobatae Radix) and Baizhi (Angelicae Dahuricae Radix) as envoy herbs entering the Yangming muscle layer. After two doses, pain and itching were significantly reduced, and appetite improved. After ten doses, the patient fully recovered.
Ziheyzi treated Han Jiqing from Yingao. From the thigh to the foot, he developed wet sores, large as coins and small as beans. When itchy, scratching caused them to break, and fluid spread like insects crawling in socks. They healed only to recur, leaving depressed scars, persisting for over ten years without healing. Ziheyzi laughed and said: "This is a wet sore, caused by water-dampness, hence often appearing on the feet." He administered Zhouchewan (Boat Cart Pill) and Jichuan Jian (River Crossing Decoction) to induce severe purgation, resulting in more than ten bowel movements, after which the disease vanished instantly.
A provincial clerk had recurrent acne and boils on his back and neck. Ziheyzi said: "This is excess blood in the Taiyang channel." He first induced vomiting to drain pathogenic factors, then pricked the Weizhong (BL40) acupoint to release dark purple blood, after which the disease never recurred. Mr. Zhang Gongchang liked to bake his back and feet with hot fires and consumed meat from dead animals. Over time, his feet frequently developed boils that recurred for over half a month. He was given Qingliang Yinzi (Cooling Drink) to purge, expelling accumulated dark purple-black blood in stool. After more than a month, the accumulated toxins were removed, demonstrating how accumulated heat-toxins cause abscesses.
Xue Lizhai treated the wife of scholar Shen Nichuan. In summer, she developed facial acne and boils. Due to exposure to cool air and wind, her face and eyes swelled. Two days later, her left arm became swollen and painful, with urticaria resembling erysipelas. Swollen lumps appeared on her back, flanks, thighs, and legs. The skin color was not red, but pain was severe, causing day-and-night crying. She experienced alternating chills and fever and lost her appetite. Huoming Yin (Life-Saving Decoction) and Qi-moving detoxifying agents worsened the condition. The liver pulse was floating and choppy; the spleen pulse was wiry and weak. This indicated disharmony of Ying-nutrient qi in these two channels, with wind pathogens invading the meridians due to deficiency. First, Bazhen Tang (Eight-Treasure Decoction) plus Huangqi, Chaihu (Bupleuri Radix), and Qingpi (Citri Reticulatae Pericarpium) was used, causing the lumps to gradually turn red. Then, Shiquan Dabu Tang (Ten Substances Great Tonifying Decoction) plus Jinyinhua (Lonicerae Japonicae Flos), Baizhi, Longdancao (Gentianae Radix), and Beimu (Fritillariae Bulbus) was administered for over ten doses. The flank and leg lesions ulcerated, discharging about a bowl of pus, while other lumps flattened. Continued administration of Shiquan Dabu Tang for a month led to stability. Had purely wind-dispelling and toxic-clearing methods been used, failure would have been inevitable.
Zhang Zhongan treated frostbite using Huangbai (Phellodendri Cortex) calcined to retain its properties, ground fine, and mixed with egg white for topical application. For broken skin, dry powder was applied directly, yielding miraculous results.
For summer skin ulcers caused by scratching or sitting/lying on damp ground during heavy sweating, a wet nurse suggested applying dry wall soil powder, which healed immediately.
For stubborn malignant sores unresponsive to various medicines, old rice formed into tight balls, calcined, and mixed with sesame oil and Nifen (Calomel) was applied. Su Taoguang suffered from fragmented sores above the ear for over two months with pain and itching, unresponsive to hundreds of medicines. Ji Changchuan shared this formula. Initially skeptical, Su tried it and healed daily. When it recurred in the Xin Chou year, Lv Xianmo advised treating summer phlegm-fluid retention patterns. Thus, soap calcined to retain properties, mixed with raw oil and Nifen, proved excellent.
Xue Lizhai treated a 43-year-old man who, since age 40, experienced summer fevers and fatigue, worsening at noon and improving in the evening. Facial sores appeared, along with slight swelling of tendons below the ear and three to four small nodules attached to the tendons. Xue diagnosed this as "Zhuxia" (Summer Malaise) caused by kidney yin deficiency failing to control heart fire due to sexual indiscretion in summer. The patient rejected this, taking cooling and detoxifying herbs, which exacerbated dry mouth, fatigue, night fevers, afternoon leg weakness, hot soles, and tendon pain. Xue explained: Dry mouth and fatigue indicate sinking of middle qi; night fever indicates yang qi sinking into the yin level; afternoon leg weakness and hot soles indicate severe yin deficiency with hyperactive fire; tendon pain indicates blood deficiency failing to nourish tendons. Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with minimal Chaihu and Shengma (Cimicifugae Rhizoma), plus Wuweizi (Schisandrae Fructus), Maidong (Ophiopogonis Radix), and Shudi (Rehmanniae Radix Preparata) resolved symptoms quickly. Zishen Wan (Nourish Kidney Pill) completed the cure. Using cold/detoxifying herbs for seasonal symptoms could be dangerous. Headache, leg weakness, poor appetite, and body heat in late spring/early summer with a wiry-large pulse match Zhang Zhongjing’s description of "worse in spring/summer, better in autumn/winter," known as Zhuxia.
The Prefect of Zhaozhou, a northerner over forty, had multiple head/face sores preferring cold drinks, unbroken for days despite clearing heat/detoxifying meds. His pulse was rapid but firm on pressure. Fengwang Tongsheng San cured him in two doses, followed by Jingfang Baidu San (Aster and Saposhnikovia Detoxifying Decoction). Another male with limb sores, also excess pattern, healed with Huanglian Jiedu Tang (Coptis Detoxification Decoction).
Miu Zhongchun treated a woman with an arm boil using Liaoqiao, Baizhi, Baiji (Bletillae Rhizoma), Huafen (Trichosanthis Radix) each 2 qian; Ganju (Chrysanthemi Flos) 1 liang; Zihuadiding (Viola Herba) and Jinyinhua (Lonicerae Japonicae Flos) each 5 qian; Gancao, Shengdi, Qiancao (Rubiae Radix) each 3 qian; Diyu (Sanguisorbae Radix) 4 qian; Zaoci (Gleditsiae Spina) and Niubangzi (Arctii Fructus) each 1 qian. Pus and blood drained within half a day, curing her. For a man with a knee boil, adding Niuxi (Achyranthis Bidentatae Radix) 3 qian caused immediate rupture and bleeding, curing him.
Ding Youwu’s verified formula for bedsores: Songxiang (Rosin) 5 qian, Xionghuang (Realgar) 1 qian, ground fine. For wet/itchy cases, add Cangzhu 3 qian. Mix powders, wrap in cotton paper, twist into two torches, soak in December pig lard, ignite, and collect dripping oil for topical application.
Xue Lizhai treated a man over forty with weak stomach qi, frequent facial sores, night sweats, and fever. Huangqi Jianzhong Tang (Astragalus Decocting Middle Decoction) helped slightly; Buzhong Yiqi Tang resolved it. Li Dongyuan stated: Qi deficiency leads to loose interstices, allowing pathogens to invade muscles, causing sores. Sweet-warm tonics strengthen the root, securing interstices and preventing disease.
Zhang Sheng developed lacquer dermatitis with vomiting due to weak middle qi and lacquer toxicity. Liujunzi Tang (Six Gentlemen Decoction) plus Sharen (Amomi Fructus), Huoxiang (Agastaches Herba), and Jiushaoyao (Paeoniae Radix Alba preparata) worked. Ignoring this, he took Liaoqiao Xiaodu San, worsening vomiting. Returning to the original prescription plus external iron rust powder mixed in sesame oil cured him.
Zhao Qianbing had leg sores; detoxifying herbs caused loss of appetite and swelling, indicating spleen deficiency with damp-heat sinking. Liujunzi Tang plus Cangzhu, Shengma, and Jiushaoyao internal, plus a plaster of Huangla (Yellow Wax), sesame oil, and Qingfen (Calomel) external cured him. Lower body sores are rarely unrelated to spleen/kidney deficiency.
A man with damp-heat sinking causing leg sores healed with Renshen Baidu San plus Cangzhu and Huangbai internally, and Jinhuang San (Golden Yellow Powder) externally. Another chronic case healed with Chu Ban Hui (Ship Board Ash) and Qingfen externally, plus Huangbai, Zhimu (Anemarrhenae Rhizoma), Fangji (Stephaniae Tetrandrae Radix), Longdancao, Fuling, Danggui (Angelicae Sinensis Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Huangqi, and Baizhu internally. Body-wide or leg pain responds to Danggui Niantong Tang (Angelica Pain-Relieving Decoction).
A woman with purple-dark ankles scratched open leaked fluid. Wind-dispelling/blood-letting agents flattened it over a year. Caowu (Aconiti Kusnezoffii Radix) caused generalized itching, bloody discharge, internal heat, fatigue, anorexia, and amenorrhea (pulse large-rapid-choppy). Dry herbs damaged spleen blood. Buzhong Yiqi Tang plus Baishao (Paeoniae Radix Alba), Chuanxiong, and Wuweizi for ten doses, then Jiawei Xiaoyao San (Modified Free Wanderer Powder) plus Shudi and Gouteng (Uncariae Ramulus Cum Uncis) for twenty doses, finally Guipi Tang (Restore the Spleen Decoction) plus Chuanxiong and Shudi prevented recurrence.
A ascetic woman had limb lesions like tinea/eczema, weeping when itchy, reddening with anger. Wind-detox herbs turned redness into weeping sores, with afternoon fever, night sweats, amenorrhea, dry mouth, and sore throat. This was depression injuring spleen blood. Guipi Tang and Xiaoyao San cured her in two months.
A scholar eating rich foods had fever, thirst for cold drinks, leprosy-like sores, and black stools. Cold herbs worsened it. Blood-level heat required cooling. Siwu Erlian Tang (Four Substances with Two Coptises Decoction) cooled blood; Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) nourished kidney yin. Chaihu Zhizi San (Bupleurum and Gardenia Decoction) finished treatment.
An irritable woman with irregular menses, internal heat, bitter taste, and sores worsened by detox herbs had weeping, fever, headache, and afternoon exacerbation. Jiawei Xiaoyao San helped. Anger caused flooding menstruation, red eyes, tearing. Siwu Tang plus Zhizi, Chaihu, Huangqin, and Huanglian cured her. Later, white spots on limbs grew with scaling, night sweats, and bi-monthly menses. Anger triggered chills/headache, chest distension, abdominal pain, hematuria, dysuria, or leukorrhea. Liver wood suppressing spleen earth with qi deficiency caused these changes. Buzhong Yiqi Tang plus Heishanzhi (Black Gardenia) and Jiawei Guipi Tang alternately cured her in six months.
A chronically depressed woman with limb sores (ankles worse) worsened by cold/detox herbs developed afternoon fever, sweats, amenorrhea, dry mouth/throat. Depression-fire injured spleen. Guipi Tang and Xiaoyao San for fifty doses cured her.
Liu Songhuang’s experience: Chen Yutian’s wife had "Heaven Snake" venomous sores. An old man used a water snake, removing head/tail, scraping flesh, wrapping the skin around the finger. It tightened naturally, wrapped in paper. The patient felt whole-body cooling, and the disease healed. Days later, a groove like a fly was found on the finger, and a complete small snake inside the skin.
Sun Simiao touched a tree with his left middle finger on July 15, 731 AD. By dawn, unbearable pain ensued. Ten days later, the sore rose high, colored like cooked adzuki beans. Using a formula heard from elders, Pugnongying (Taraxaci Herba) juice applied cured it immediately, though it relapsed before ten days passed.
Ziheyzi noted: Master Ma’s wife had unbearable toe pain. Tongjing San (Unblocking Channels Powder) 1.5 qian with wine induced vomiting, relieving pain. He recalled Chen Wuzeng’s similar case misdiagnosed as insect bite or toxic plant contact, lasting months until pus drained. This formula made him laugh.
Wang Sizhong treated a man with pox and scrotal swelling like a bucket, unable to walk. Diagnosed as "Sores Gu," adding forty-nine wheat stalks to surgical herbs resolved it.
During the flood of Wushen year, immersion caused painful skin sores. Bathing in boiled Shuijingtiao (Vitex trifolia var. simplicifolia) branches cured it instantly.
In Liangxi, a man with a painful knee boil was treated by Miu Zhongchun. After drinking several cups of wine with the prescription, the boil ruptured with fresh blood, curing him. Formula: Liaoqiao 3 qian, Baizhi 2 qian, Fen Gancao (Licorice) water-fried 3 qian, Jinyinhua 5 qian, Niuxi 3 qian, Shengdi 3 qian, Diyu 4 qian, Zaoci 1 qian, Niubangzi (Niuniuzi) wine-fried and ground 1 qian.
