《鬼遗方》云∶凡痈疽外冷内疼者，由阴气外逼，用热物熨之，大热亦不觉者，须用
热物熨令透，随手便用紧急溃脓药，使脓外出尽，肿平即用生肉暖疮和正气药，令进饮
食不倦。
治痈疽、发背，初肿时方
风化锻石（二两） 细辛（一两）
上为粗末。用热醋敷患处干再敷，三上其肿即消。
四虎散 治发背初生，筋脉紧急不舒。
附子（生，去皮，一两） 天南星 半夏 野狼毒（各半两） 一方，无附子，有草乌各等分。
上四味为末。热酒调成膏，摊上肿处，以熟绢压定，觉患处如火烧，不妨。
回阳玉龙膏
草乌头（三两，炒） 南星（一两，煨） 军姜（二两，煨） 白芷（一两，不见火） 赤芍药（一两，
炒） 肉桂（半两，不见火）
此方治阴发背，冷流注，鼓椎风，久损痛，冷痹风湿，诸香港脚冷肿，无红赤者，冷
肿不痛者，足顽麻痹，妇人冷血风，诸阴证之第一药也，用热酒调涂，用法详具于后。夫
杂病虽见于皮肤手足之间，而因必本于五脏六腑。盖脏腑之血脉、经络，一身昼夜营运，
周而复始，一脏受病，必见于本脏脉息所经之处，即阴阳分手足之所属也。为病有冷有
热，热者易治，冷者难疗。夫冷必由脏腑元阳虚弱，然后风邪得以乘间而入，血气不匀，
遂自经络而客于皮肤之间，脉息不能周流，遂涩于所滞，愈冷则愈积而不散，复加庸医用
凉剂，而内外交攻，则其为病，鲜有不危者矣。学人当观其外之为证，而察其内之所属，
表里相应，万无一失。此药有军姜、肉桂，足以热血、生血，然既生既热而不能散，又反
为害，故有草乌、南星，足以破恶气，驱风毒，活死肌，除骨痛，消结块，唤阳气，又
有赤芍、白芷，足以散滞血，住痛苦，生肌肉，加以酒行药性，散气血，虽十分冷证，未
有不愈，端如发寒灰之焰，回枯木之春。大抵病冷则肌肉阴烂，不知痛痒，其有痛者，又
多附骨之痛，不除则寒根透髓，非寻常之药所能及，惟此药大能逐去阴毒，迎回阳气，住
骨中痛，且止肌肉皮胃之病，从可知矣，当斟酌用之，不可太过，则为全美。一发背发
于阴，又为冷药所误，又或发于阳，而误于药冷，阳变为阴，满背黑烂，四围好肉上，用
洪宝丹把住，中间以此药敷之。一夜阳气回，黑者皆红，察其红活，即住此药，却以冲和
仙膏收功。如不效欲作脓，又以南星、草乌，加于冲和用之。如阳已回，黑已红，惟中间
一点黑烂不能红者，盖血已死，可以朴硝、明矾。又云∶白丁香、 砂、乳香，用唾调匀，
于黑红交处作一圈，上用冲和盖之，至明早起药，自然去黑肉如割，却以药洗之， 以
生肉合口药收功。一流注冷证，多附骨内硬不消，骨寒而痛，筋缩不伸，若轻用刀针，并
无脓血，若止有乳汁清流，或有瘀血，宜用此药敷之；若稍缓，止以军姜、白芷、肉桂、
草乌等分，热酒调敷，骨寒除而痛止，则气温和而筋自伸，肉硬自消矣。然治流注，不
可无木蜡，以其能破积滞之气，消坚硬之肿最妙，又不可多，多则能解药性，盖此证主
于温药故也。一鼓椎风，起于中湿或伤寒余毒，又或起于流注之坏证，或起于风湿虚痹，
此证有三∶一是两膝相 ，行步振掉，膝HT 胫骨微肿；二是膝HT 胫骨交接处，大如椎腿
股，肉消皮缩裹骨；三是上腿肿大，下股冷消。盖足膝属肝，肝经有风寒湿气，则血脉
不流而作此，遂为膝寒，所涩凝流不动，下股之血脉，有去无返，是以愈瘦愈冷而筋愈
缩，上腿之血脉有积而无散，是以愈肿愈热而肉愈瘦。其原若起于流注，则肉凝者为烂，
烂则冷毒腐骨，腐骨一出，神仙无术。未破则肌肉尚未死，急以此药，热酒调敷膝HT 骨
腿处，以住骨痛，回阳气。又以冲和涂下腿
冷处，引其血气，使流动而下通贯血脉，又以此方敷胫骨交处，以接所引之血脉，以散
所积之阴气，内用追风丸，倍加乳香以伸筋，如法服之，无不愈者。如人欲出方，可用五
积散加姜、桂、芷、归。又加大川芎、牛膝、槟榔、木瓜，或茶或酒调之。一男子、妇人
久患冷痹血风，手足顽麻，或不能举动，可用绵子夹袋此药在中心，却以长片缠在痛处，
用绢袋系定，此药能除骨痛，附在肉上，觉皮肤如蚁缘，是其功也。如痹可加丁皮、吴
茉萸、没药、大川乌等分，然后全在追风丸，表里交攻，去病如神。一风脚痛不可忍，内
用追风丸，外用此方，加生面、姜汁调热敷。欲得立止，可根据法加乳香、没药化开，酒调
为妙。一久损入骨者，盖因坠压跌扑伤折，不曾通血，以至死血在所患之处，久则如鸡肺
之附肋，轻者苔藓之晕石。年少之时，血气温和，尤且不觉，年老血衰，遇风寒雨湿，其
病即发，宜此方热酒调敷，内则用搜损寻痛丸，表里交攻为妙。虽然血气虚弱之人，病
在胸肋腰背之间者，谓之脱垢，不除变为血结劳，不论老少，年远近岁，大而遍身，小
而一拳半肘，医之则一，此等乃根蒂之病，则非一剂可愈，磨以岁月方可安，未成劳者易
已，成劳者难。一法只用南星、草乌，加少肉桂，能去黑烂溃脓，谓之小玉龙，此法大
效。一治石痈用此方，热酒调敷，外却用洪宝，箍住四围，待成脓后破。一妇人乳痈，多
因小儿断乳之后，不能回化；又有妇人乳多，孩儿饮少，积滞凝结；又为经候不调，逆行
失道；又有邪气内郁而后结成痈肿。初发之时，切不宜用凉药冰之，盖乳者血化所成，不
能漏泄，遂结实肿核，其性清寒，若为冷药一冰，凝结不散，聚久而外血不能化乳者，方
作热痛，蒸逼乳核而成脓，其苦异常，必烂尽而后已，故病乳痈者，既愈则失其乳矣。盖
乳性最寒，而又滞以凉剂，则阴烂宜也，然凉药亦未尝不用，用于既破之后则佳，如初
发之时，宜于此方中用南星、姜汁、酒两停调匀热敷，即可内消。欲急则又佐以草乌，此
药味性烈，能破恶块，逐寒热，遇冷即消，遇热即溃。如已成痈肿，则又从冲和，根据常法
用之。或加此草乌、南星二味，亦可破后观其原，原于冷用冲和收功，原于热用洪宝生
肌，且须用乳、没住痛，以减其苦。至于吃药，只用栝蒌散，随人虚实，参以通顺散、十
宣相间服之。多口者，为乳发，乳房坚硬者，为乳石，正在乳嘴处肿者，为吹乳，在乳兜
囊下，为乳漏，以肉悬垂而血易满故也，故为难治。一囊一口为乳痈，五十岁老人无治
法外，有老人乳节，又为可治，盖在垂囊肉上为痈，若近胸则为节矣。一宿痰失道，痈
肿无脓者，可用此药点头，病必旁出，再作为佳，不然，则元阳虚耗，此为败证。如元
阳虚耗败证者，急用全体玉龙敷之，拔出成脓，服药则通顺散加桔梗、半夏、当归、肉
桂等药。若病红活热骤，则当归冲和为佳，切不可误投凉剂，此方但能拔毒作脓，病回即
止不可过。若能参用陷脉神剂尤妙，出《外科精要》。一肚痈一证，十有九死，盖胃属阴，
外寒里热，凡气血潮聚，驱热避寒，故多为内痈，不能外现，间有微影欲出，则又为冷
药所触，及服凉剂，虽有神仙莫施其功，医者可不慎乎！凡有此证，初觉腰痛，且以手
按之痛。若走闪移动，则为气块；若根不动，外面微有红肿，则为内痈。急以此方拔出毒
气，作成外痈，然后收功冲和，内则用通顺散加忍冬藤，治法如前。若痈自能外现者，不
必用此方，只用冲和为妙，不可轻用针刀。如犯铁器，口不能合，只用玉龙贴痈头上，四
面以冲和围之，根据法自破。若脓流不快，根据法用洪宝三分，姜汁七分，茶调敷之，脓出
皆尽，内用十宣、平补生肌外，则依然收功冲和。此证阴多阳少，损人最甚，将安之际，
倍服内补，以生气血，庶几易愈，否则消而复胀，口不合。既安之后，尤宜多服内补加
附子，否则气弱难平。证冷者，未破之先，尤宜先服附子方好，既破之后，切不可用急涩、
敛口之药，恐食毒不散，服药力到，自然合口。至于内痈已成，不能拔出，只用冲和外
贴，使在外温和成脓，自脏腑而出，不至肉烂，死生所系，全在服药之功，治法见前。最
忌毒食，食毒即发，反复难疗。又有孕妇病此者，又与此异，内用紫苏饮安胎，勿轻与
他药。若临月，则儿与脓俱下，若尚远，则脓自大腑中下。若初萌只服药可消，若痈在
外面，其证必热，惟可用冲和收功，亦须审轻重用之，恐有误也。
《鬼遗方》说：凡是痈疽表现为外部发冷、内部疼痛的，是由于阴气在外部逼迫所致，需要用热物熨烫；如果即使使用很热的东西熨烫也感觉不到热度，必须用热物熨烫直到热气透入，随即立即使用紧急溃脓的药物，使脓液完全排出体外，待肿胀消退后，就使用生肌、暖疮以及调和正气的药物，让患者能够不倦地进食。
治疗痈疽、发背，在初起肿胀时使用的方子：
风化锻石（二两） 细辛（一两）
将上述药材捣成粗末。用热醋调敷患处，干了再敷，反复三次，肿胀即可消除。
四虎散：治疗发背初起，筋脉拘急不舒展。
附子（生用，去皮，一两） 天南星 半夏 野狼毒（各半两） 另一版本，没有附子，有草乌，各等分。
将以上四味药研成粉末。用热酒调成膏状，摊涂在肿胀处，用熟绢布压固定，感觉到患处像火烧一样，不要紧。
回阳玉龙膏
草乌头（三两，炒制） 南星（一两，煨制） 军姜（二两，煨制） 白芷（一两，不见火） 赤芍药（一两，炒制） 肉桂（半两，不见火）
此方治疗阴证发背、冷性流注、鼓椎风、久病损伤疼痛、冷痹风湿、各种香港脚冷肿且无红赤色的、冷肿不痛的、足部顽固麻痹、妇人冷血风，是治疗各种阴证的首选药物。用热酒调匀涂抹，具体用法详见后文。大凡杂病虽然表现在皮肤手足之间，但病因必然根源于五脏六腑。因为脏腑的血脉经络，在全身昼夜运行，周而复始，一个脏器受病，必然表现在本脏经脉所经过的地方，也就是阴阳分属手足的部位。疾病有冷有热，热证容易治疗，冷证难以治愈。冷证必定是因为脏腑元阳虚弱，然后风邪得以乘虚而入，导致气血不调，于是从经络客居于皮肤之间，脉搏气息不能周身流通，于是在停滞之处变得涩滞，越冷则积聚越深而不消散，再加上庸医使用凉剂，内外交攻，那么这种病很少有不至于危险的。学者应当观察外部的症状，从而推察内部的所属脏腑，表里相应，万无一失。此药含有军姜、肉桂，足以温热血脉、生发血液，然而既然已经生热却不能消散，反而成为危害，所以又有草乌、南星，足以破除恶气，驱除风毒，活化死肌，消除骨痛，消散结块，唤醒阳气，又有赤芍、白芷，足以疏散滞留之血，停止痛苦，生长肌肉，再加上酒来行药性，疏散气血，即使是十分严重的冷证，也没有不痊愈的，确实如同吹燃寒灰之火，恢复枯木之春。大抵冷证会导致肌肉腐烂，不知痛痒，如果有疼痛的，又多属于附骨痛，如果不除去，寒气深入骨髓，不是寻常药物所能达到的，只有此药能大力驱逐阴毒，迎回阳气，止住骨中疼痛，并且治疗肌肉皮肤的疾病，由此可知，应当斟酌使用，不可过量，才能完美。一发背生于阴经，又被冷药误治，或者生于阳经而误用冷药，导致阳证变为阴证，满背黑烂，在周围好肉上，用洪宝丹箍住四周，中间用此药敷贴。一夜之后阳气回复，黑色变红，观察到红色鲜活，就停用此药，改用冲和仙膏收功。如果无效欲作脓，又在冲和仙膏中加入南星、草乌使用。如果阳已回复，黑已变红，唯独中间一点黑烂不能变红的，那是血已死，可以用朴硝、明矾。又说：白丁香、砂、乳香，用唾液调匀，在黑红交界处画一圈，上面用冲和仙膏覆盖，到第二天早上去掉药，自然去除黑肉如切割一般，然后用药物清洗，再用生肌合口药收功。一流注冷证，多附着于骨内坚硬不消，骨寒而痛，筋缩不能伸展，如果用轻刀针，并无脓血，如果仅有乳汁样的清流，或有瘀血，宜用此药敷贴；如果稍缓，只用军姜、白芷、肉桂、草乌等分，热酒调敷，骨寒除而痛止，则气温和而筋自然伸展，肉硬自然消除。然而治疗流注，不可不用木蜡，因为它能破除积滞之气，消除坚硬的肿块最好，但又不可多用，多用则能解药性，因为这个证候主于温药。一鼓椎风，起因于中湿或伤寒余毒，或者起因于流注的坏证，或者起因于风湿虚痹，这个证候有三种：一是两膝相并，行走时颤抖摇晃，膝盖和小腿胫骨微肿；二是膝盖和小腿胫骨交接处，大如椎腿股，肉消皮缩包裹骨头；三是大腿肿大，小腿冷瘦。因为足膝属肝，肝经有风寒湿气，则血脉不流而发作此病，遂成为膝寒，涩滞凝流不动，小腿的血脉，有去无返，所以越瘦越冷而筋越缩，大腿的血脉有积而无散，所以越肿越热而肉越瘦。其根源如果起于流注，则肉凝结者为腐烂，腐烂则冷毒腐骨，腐骨一出，神仙也无办法。未破溃则肌肉尚未死，急忙用此药，热酒调敷膝盖和小腿胫骨处，以止住骨痛，回阳。又用冲和仙膏涂在小腿冷处，引导其血气，使其流动而下通贯血脉，又用此方敷贴在胫骨交接处，以接续所引导的血脉，以消散所积聚的阴气，内服追风丸，倍加乳香以舒筋，依法服用，没有不愈的。如果有人想开方，可用五积散加姜、桂、芷、归。再加川芎、牛膝、槟榔、木瓜，或用茶或酒调服。一男子、妇人久患冷痹血风，手足顽麻，或不能举动，可用绵子夹袋装此药在中心，再用长片缠在痛处，用绢袋系定，此药能除骨痛，附在肉上，感觉皮肤如蚂蚁爬行，这是它的功效。如果痹症可加丁皮、吴茱萸、没药、大川乌等分，然后全凭追风丸，表里交攻，去病如神。一风脚痛不可忍受，内服追风丸，外用此方，加生面、姜汁调热敷。想要立刻停止疼痛，可根据法加入乳香、没药化开，酒调为妙。一久病损伤入骨的，大概是因为坠压跌扑伤折，不曾通畅血脉，以至死血在所患之处，久了就像鸡肺附着肋骨，轻者像苔藓晕石。年少之时，血气温和，尚且不觉，年老血衰，遇风寒雨湿，其病即发，宜此方热酒调敷，内则用搜损寻痛丸，表里交攻为妙。虽然血气虚弱之人，病在胸肋腰背之间的，称为脱垢，不除去变为血结劳，不论老少，年岁远近，大而遍身，小则一拳半肘，医治方法一样，这些乃是根蒂之病，则非一剂可愈，需磨以岁月方可安康，未成劳者易治，成劳者难。一法只用南星、草乌，加少量肉桂，能去黑烂溃脓，称为小玉龙，此法大效。一治疗石痈用此方，热酒调敷，外面却用洪宝丹，箍住四周，待成脓后破溃。一妇人乳痈，多因小儿断奶之后，不能回化；又有妇人乳汁多，孩子喝得少，积滞凝结；又有因月经不调，逆行失道；又有邪气内郁而后结成痈肿。初发之时，切不宜用凉药冰伏它，因为乳汁是由血化成的，不能漏泄，遂结实肿核，其性清寒，如果被冷药一冰，凝结不散，聚久之后外部血液不能化为乳汁的，才发作热痛，蒸逼乳核而成脓，其痛苦异常，必须烂尽而后已，所以患乳痈的人，既然后痊愈则失去其乳汁了。因为乳性最寒，而又被凉剂阻滞，则阴烂是应该的，然而凉药也未尝不用，用在破溃之后则佳，如初发之时，宜于此方中用南星、姜汁、酒两停调匀热敷，即可内消。想要急效则又佐以草乌，此药味性猛烈，能破除恶块，驱逐寒热，遇冷即消，遇热即溃。如果已成痈肿，则又从冲和仙膏，根据常法使用。或加此草乌、南星二味，也可在破溃后观察其原由，原于冷用冲和收功，原于热用洪宝生肌，且须用乳香、没药止住疼痛，以减少其痛苦。至于吃药，只用栝蒌散，随人虚实，参以通顺散、十宣散相间服用。多口者，称为乳发，乳房坚硬者，称为乳石，正在乳嘴处肿者，称为吹乳，在乳兜囊下，称为乳漏，因为肉悬垂而血易满的缘故，所以难治。一囊一口为乳痈，五十岁老人无法治疗，外有老人乳节，又为可治，因为在垂囊肉上为痈，若靠近胸部则为节了。一宿痰失道，痈肿无脓者，可用此药点头，病必旁出，再作为佳，不然，则元阳虚耗，此为败证。如果元阳虚耗败证者，急忙用全体玉龙敷贴，拔出成脓，服药则通顺散加桔梗、半夏、当归、肉桂等药。如果病色红活热骤，则当归冲和为佳，切不可误投凉剂，此方只能拔毒作脓，病回即止不可过量。如果能参用陷脉神剂尤妙，出自《外科精要》。一肚痈一证，十有九死，因为胃属阴，外寒里热，凡气血潮聚，驱热避寒，故多为内痈，不能外现，间有微影欲出，则又被冷药所触，及服凉剂，虽有神仙莫施其功，医者可不慎重啊！凡有此证，初觉腰痛，且用手按之痛。如果走闪移动，则为气块；如果根部不动，外面微有红肿，则为内痈。急忙用此方拔出毒气，作成外痈，然后收功用冲和，内则用通顺散加忍冬藤，治法如前。如果痈自能外现者，不必用此方，只用冲和为妙，不可轻用针刀。如果犯铁器，口不能合，只用玉龙贴痈头上，四面以冲和围之，根据法自然破溃。如果脓流不快，根据法用洪宝三分，姜汁七分，茶调敷之，脓出皆尽，内用十宣、平补生肌外，则依然收功用冲和。此证阴多阳少，损人最甚，将安之际，倍服内补，以生气血，庶几易愈，否则消而复胀，口不合。既安之后，尤宜多服内补加附子，否则气弱难平。证冷者，未破之先，尤宜先服附子方好，既破之后，切不可用急涩、敛口之药，恐食毒不散，服药力到，自然合口。至于内痈已成，不能拔出，只用冲和外贴，使在外温和成脓，自脏腑而出，不至肉烂，死生所系，全在服药之功，治法见前。最忌毒食，食毒即发，反复难疗。又有孕妇病此者，又与此异，内用紫苏饮安胎，勿轻与他药。若临月，则儿与脓俱下，若尚远，则脓自大腑中下。若初萌只服药可消，若痈在外面，其证必热，惟可用冲和收功，亦须审轻重用之，恐有误也。
The *Gui Yi Fang* states: Whenever a carbuncle or ulcer presents with external coldness and internal pain, it is caused by Yin pathogenic factors pressing from the exterior. One should apply hot compresses; if even intense heat fails to elicit sensation, one must use hot compresses until the heat penetrates thoroughly, then immediately apply urgent pus-draining formulas to ensure complete evacuation of pus. Once swelling subsides, employ flesh-regenerating, warming, and Qi-nourishing medicines to facilitate continuous appetite.
For treating carbuncles, ulcers, and back abscesses during initial swelling:
Fenghua Duan Shi (Calcined Iron Pyrite, 2 liang) and Xixin (Asarum, 1 liang).
Grind these into coarse powder. Apply with hot vinegar to the affected area; reapply when dry. After three applications, the swelling will subside.
Si Hu San (Four Tigers Powder): Treats early-stage back abscesses characterized by tense and uncomfortable meridians and vessels.
Fuzi (Aconite Lateralis Radix Praeparata, raw, peeled, 1 liang), Tian Nanxing (Arisaema Cum Bile, 0.5 liang), Banxia (Pinelliae Rhizoma, 0.5 liang), Yelangdu (Stemonae Radix, 0.5 liang). An alternative prescription excludes Fuzi and uses Caowu (Aconiti Kusnezoffii Radix) in equal parts.
Grind the four ingredients into powder. Mix with hot wine to form a paste, spread on the swollen area, and secure with cooked silk cloth. A sensation of burning in the affected area is acceptable and not harmful.
Hui Yang Yu Long Gao (Return Yang Jade Dragon Ointment)
Caowutou (Aconiti Kusnezoffii Radix, 3 liang, stir-fried), Nanxing (Arisaema Cum Bile, 1 liang, baked), Jiangzhu (Zingiberis Rhizoma Recens, 2 liang, baked), Baizhi (Angelicae Dahuricae Radix, 1 liang, protected from fire), Chishao (Paeoniae Radix Rubra, 1 liang, stir-fried), Rougui (Cinnamomi Cortex, 0.5 liang, protected from fire).
This formula treats Yin-type back abscesses, cold Liuzhu (flowing deposits), Guzhuifeng (drum-pounding wind), chronic injury pain, cold Bi syndrome with wind-dampness, various Hong Kong foot conditions with cold swelling lacking redness, cold swelling without pain, stubborn numbness of the feet, women’s cold blood-wind, and is the premier medicine for all Yin syndromes. Apply mixed with hot wine; detailed usage follows. Generally, miscellaneous diseases manifest on the skin and extremities but originate in the Zang-Fu organs. The blood vessels and meridians of the Zang-Fu circulate throughout the body day and night, completing cycles. Disease in one organ manifests at points along its meridian pathway, corresponding to Yin-Yang divisions of the limbs. Diseases are either cold or hot; hot syndromes are easy to treat, while cold syndromes are difficult. Cold syndromes arise from deficiency of Yuan Yang (Primordial Yang) in the Zang-Fu, allowing Wind pathogens to invade due to disharmony of Qi and Blood. Pathogens lodge in the skin via meridians, obstructing pulse flow, causing stagnation. Greater cold leads to deeper accumulation. If quacks administer cooling agents, internal and external attacks compound the condition, often leading to critical danger. Practitioners must observe external signs to infer internal organ involvement, ensuring correspondence between interior and exterior for success. This ointment contains Jiangzhu and Rougui to warm and generate blood. However, warmth alone cannot disperse stagnation and may cause harm; thus, Caowu and Nanxing are included to break evil Qi, expel wind-toxins, revitalize necrotic tissue, relieve bone pain, dissipate nodules, and awaken Yang Qi. Chishao and Baizhi disperse stagnant blood, alleviate pain, and promote flesh growth. Wine enhances drug efficacy, disperses Qi and Blood. Even severe cold syndromes will heal, akin to reigniting cold ashes or restoring spring to dead wood. Cold syndromes cause muscle rot and loss of sensation; pain indicates deep attachment to bone. Without removal, cold roots penetrate marrow, beyond the reach of ordinary drugs. Only this ointment can vigorously expel Yin toxins, restore Yang, stop bone pain, and treat skin/muscle disorders. Use with caution to avoid excess. For a back abscess arising from Yin channels and mistreated with cold herbs, or a Yang-channel abscess mistreated with cold herbs turning Yin with black rot over the back, apply Hongbao Dan around the healthy perimeter and this ointment in the center. After one night, Yang returns, black turns red. Once vibrant red appears, stop this ointment and finish with Chonghe Xian Gao. If ineffective and suppuration is desired, add Nanxing and Caowu to Chonghe. If Yang returns and black turns red except for a central point of black rot indicating dead blood, use Poxiao (Natrii Sulfas) and Mingfan (Alumen). Alternatively, mix Baixiangding (Bubali Corneum), Sha (Realgar), and Ruxiang (Olibanum) with saliva, draw a circle at the black-red border, cover with Chonghe. Remove next morning; dead flesh falls off easily. Clean with medicine and finish with flesh-regenerating agents. Cold Liuzhu syndromes often present as hard, non-resolving masses attached to bone with cold pain and contracted tendons. Needle aspiration yields no pus, only milky fluid or stasis. Apply this ointment. For milder cases, mix Jiangzhu, Baizhi, Rougui, and Caowu equally, apply with hot wine. As bone cold resolves and pain stops, warmth restores tendon extension and softens hardness. Wood wax (Muzha) is essential for Liuzhu to break stagnation and reduce hardness, but use sparingly as excess neutralizes efficacy; this syndrome requires warming herbs. Guzhuifeng arises from dampness, residual toxicity from Shanghan, deteriorated Liuzhu, or wind-damp deficiency Bi. Three types exist: 1) Knees touching, trembling gait, slight swelling of knees and shins; 2) Swelling at knee-shin junction resembling thigh, with skin shrinking around bone; 3) Thigh swelling with cold, wasted calf. Knees belong to Liver; wind-cold-damp in Liver channel obstructs blood flow, causing knee cold. Stagnant flow prevents return circulation in calves, leading to wasting and coldness with tendon contraction. Accumulation in thighs causes swelling, heat, and wasting. If originating from Liuzhu, condensed flesh rots, cold toxin corrupts bone; once bone corruption occurs, even immortals cannot save. Before rupture, flesh is viable; urgently apply this ointment with hot wine to knees/shins to stop bone pain and restore Yang. Apply Chonghe to cold lower legs to guide blood flow downward. Apply this formula at shin junctions to connect meridians and dissipate accumulated Yin. Internally, take Zhuifeng Wan with extra Ruxiang to extend tendons. All recover. For open prescriptions, use Wuji San plus Ginger, Cinnamon, Baizhi, Danggui, Chuanxiong, Niuxi, Binglang, Mugua, taken with tea or wine. For men/women with chronic cold Bi blood-wind causing numbness or paralysis, wrap this ointment in cotton bags, place on pain sites, secure with silk. It relieves bone pain; skin tingling like ants crawling indicates efficacy. For Bi, add Dingpi, Wuyuzhuyu, Moyao, Da Chuawu equally, combined with Zhuifeng Wan for dual action. For unbearable wind-foot pain, take Zhuifeng Wan internally, apply this formula with flour and ginger juice externally. For immediate relief, add Ruxiang and Moyao dissolved in wine. For chronic injuries penetrating bone due to trauma without blood circulation, causing static blood accumulation resembling lung tissue or mossy stones, young people may not feel it, but elderly with declining blood/qi suffer upon exposure to wind-cold-damp. Apply this ointment with hot wine; internally take Sousun Xuntong Wan. Dual action is ideal. For weak patients with chest/flank/back pain termed Degou, failure to treat leads to Blood-Stasis Consumption. Regardless of age or duration, widespread or localized, treatment is uniform. These root diseases require prolonged therapy; pre-consumption is curable, established consumption is difficult. A variant uses Nanxing, Caowu, and little Rougui to clear black rot/pus, called Xiao Yulong, highly effective. For Shi Yong (Stone Carbuncle), apply this ointment with hot wine, surround with Hongbao Dan, wait for suppuration before lancing. For female breast carbuncles, often caused by weaning retention, excessive milk with low intake causing stagnation, irregular menstruation with reversed flow, or internal pathogen郁结. Initially, avoid cooling agents as milk is transformed blood; cooling causes condensation and hard nodules. Milk is cold in nature; cooling agents exacerbate stagnation. Eventually, heat builds, forcing suppuration with extreme pain and tissue destruction, resulting in lactation loss. Although milk is cold, cooling agents are used post-rupture. At onset, mix Nanxing, ginger juice, and wine equally for hot compress to resolve internally. For rapid effect, add Caowu. Caowu is potent, breaking masses, expelling cold/heat, dissolving in cold, suppurating in heat. For established abscesses, use Chonghe normally. Add Caowu/Nanxing if needed. Post-rupture, determine etiology: cold uses Chonghe, heat uses Hongbao for flesh generation. Use Ruxiang/Moyao for pain. Internally, use Gualou San adjusted for deficiency/excess, alternating with Tongshun San and Shixuan San. Multiple openings indicate Rufa; hardness indicates Rushi; nipple swelling indicates Chuiru; sac swelling indicates RuLou (difficult due to blood accumulation). Single sac/opening is Ruping; untreatable in elderly, except Rudie (abscess on hanging flesh near chest), which is treatable. For phlegm-derived abscesses without pus, apply this ointment to induce pointing/side drainage. Otherwise, Yuan Yang depletion leads to defeat syndrome. For defeat syndrome, apply full Yulong to induce pus; internally take Tongshun San with Jiegeng, Banxia, Danggui, Rougui. If red/vibrant/hot, use Danggui Chonghe. Avoid cooling agents. This ointment draws out toxins; stop when improved. Combining with Xianmai Shenji (from Waike Jingyao) is excellent. Du Yong (Abdominal Abscess) has high mortality due to Stomach being Yin, external cold/internal heat. Qi/Blood gathers to drive out heat/cold, forming internal abscesses rarely visible. If slight protrusion occurs, cold agents trigger complications. Even immortals fail if cooled. Initial symptom is lower back pain on pressure. Moving pain indicates Qi mass; fixed root with slight redness/swelling indicates internal abscess. Urgently apply this formula to draw toxins outward, forming external abscess, then finish with Chonghe. Internally, Tongshun San with Jindingteng. If abscess naturally externalizes, use only Chonghe; avoid needles/knives. If tetanus risk (iron exposure), apply Yulong on head, surround with Chonghe; natural rupture follows. If slow drainage, use Hongbao (3 parts) and ginger juice (7 parts) with tea. When pus clears, internally use Shixuan and Pingbu Shengji, finishing with Chonghe. This syndrome has excess Yin/deficient Yang, severely damaging. During stabilization, double internal tonics to generate Qi/Blood for easier recovery; otherwise, rebound swelling and non-healing occur. Post-stabilization, continue internal tonics with Fuzi to prevent weakness. For cold syndromes, take Fuzi formulas before rupture; after rupture, avoid astringents to prevent trapping toxins; natural healing occurs as drug potency acts. For formed internal abscesses unable to be drawn out, apply Chonghe externally to gently mature pus for exit from organs, preventing tissue rot. Survival depends on medication. See previous methods. Avoid toxic foods; recurrence is hard to treat. Pregnant women have different management: internally use Zisu Yin to calm fetus, avoid other drugs. Near term, fetus and pus pass together; earlier, pus passes via large intestine. Early stage may resolve with medicine alone. External abscesses are hot; use Chonghe cautiously based on severity.
