余少年读先哲理疗书，窃谓不粗卤则过密，与己所见不合，故不终卷而已。因取仲师之
经，
一意攻之，略窥述作之旨，又质之于治术。数十年，而后阅诸家之书，始知先哲独至之本领
，悔当日不虚心凝思。从此寻绎，则至古人之域亦不难也。惜乎日暮路远，不复能与之相上
下，以成一家。然亦不能自止，姑录其一二，以为后生解悟之资云。
近世古方之学，以名古屋玄医并河天民为翘楚，而未免金元陋习。至艮山先生，豪然崛
起，
一洗从前弊风。其识见理疗，必当有迥异乎先辈者，世以为好奇非矣。盖吾医术至一溪道三
氏之门，流碎残极矣。是以享元医人复转而 古，此亦自然之势也。(拙轩曰∶一部伤风约
言，翁之本领在此，可谓善读《伤寒论》者。后来豪杰辈出，皆闻翁之风而兴起者，斯为吾
道中兴。先生起笔，兹非偶然也。)
谷肉果菜者，正性也。草木虫石者，偏性也。故古昔养精以正性者，治病以偏性者。后
人不
知此义，拟以药品补精气，盖亦误矣。(《素问》云∶五谷为养，五果为助，五菜为充，毒
药攻邪，此即医家大纲领。先生早标揭焉，而为他日东洞诸辈立论之蓝本。)
乱世人其气剽悍，肝胆气郁少。治世人其气游惰，肝胆气郁多。故宜以熊胆开其郁，令
肝胆
气达。(永富凤曰∶余征之于都邑市朝之人，比比皆然。盖太平日久，五民蕃息，金钱虚耗
，奢佚日盛，则知巧之民不免病气势也。医人施治之日从这处下工夫，则有大裨益矣。)
其人有 癖而饮食减少者，譬之于人家犹廊颓厢敝，而堂室渐狭小也。故不去 癖，则
胃不
能振。医不知此理，欲与毒药补胃气，且菲饮食，益损精液者，不亦谬乎。凡疗此症，先驱
癖，以滋味养胃气为主也。痈疽饵食鸡肉或鸡卵，能托出其毒。优于参 ，故治疮以饵食
为专一也。(徐灵胎曰∶服药原为治病而设，并非借以生长气血也。殆是同一见。)
外感以汤液为主，内伤以饵食为主，错之则不得其治也。
赤蛙不止治小儿痫，亦治大人痨，盖痫痨皆属 癖也。此品能治癖气，妨害脾胃为下利
者，
兼制蛔虫。(杨氏直指曾氏口议并云∶十五以下为疳，十五以上为瘵，颇与此说合。而二氏
徒用固阳滋阴之剂，更无发明。艮山特用 血荡气之药，以除腹里之 癖，其术高一等。)
痫利者，饵鳗鲡以炙干为可。
按腹自心下至脐，任脉突起者，病聚脉下故也。病不聚者，脉不必突起。老人肉脱发此
证者，为近死期。
按腹心下任脉左右充满有力者为实，若濡弱不充满者属虚也。
虚惫症，唇色不淡白。耳叶未萎者，可救活也。是宜熟察。
阳气浮泛者，难认肉脱之候。先诊背部，其人每咳或喘，背上陷下者，因气逆见脱肉之
痕也。此证属气胀，故名曰虚浮，不必水气也。
诊病患宜先审问曾患霉毒否，何则？今世霉毒浸淫筋骨，多元气为之壅塞者也。
病至大患目不瞬者，眼胞元气脱也。乃为反目，兆近死期。
诸病以渐成者多难治，若肉脱或有水气者不治。
凡有痛者，脉多紧弦，如太阳病头痛者是也。动与紧似相反，而紧弦者，动之甚也。动
脉变迟者，正气弛而邪气未除也，如结胸脉迟是也。盖动变迟者可救，不变而数者殆。
黄胆未发前为腹痛者，多是属 癖，又有脾脏郁结为腹痛者可辨别。(《金匮》云∶谷
气不
消，胃中苦浊，此所以湿热为腹痛。又云∶诸黄腹痛而呕者，宜柴胡汤。此系黄胆腹痛治法
。)
嗝噎一旦食进者，不可恣吃，其人原胃中虚竭，反招害。
卒中风，多系 癖塞心，故人事不省，不能活。若不塞心者，半身不遂，或口眼 斜耳
。其虽人事不省，而六脉相应，手足厥冷者，一身大气犹存，可救也。
男女俱年未壮而身不了了者，多系风寒，宜调护。若缓漫经日，则大便溏，以至重症，
故此证大便秘结为佳，溏泄为恶。
专发声音者多吐血，而脉不数，是不足畏。真吐血者，其脉必数急，是大可恐。
凡病不论六淫七情饮食男女，皆因一元气郁滞。故皮肤郁者，经络滞者，遂皆及腹里，
犹水之凑陷地，医者先得其大纲治之为要。
霉毒沉滞骨节者，经络壅塞尤甚，故发种种变证。不可不知。
其人虚弱咳嗽久不止者，此由寒气壅表，与虚火扇肺，故咳愈甚，而肺益涸。
奔豚证有肝气兼霉毒者，有肝气带疝者，但霉毒与疝不为奔豚。古语云∶诸风掉眩属肝
是也。
痉及痱之类，身体不自由者，苟健啖不运动，则脾气不能行，故四五年后必死。患此证
者，宜务运动，以行脾气，庶几终其天年。名古屋玄医曾患之，善全其终，可以证焉。
水肿咳嗽甚者，必水气辐凑上部。又水气发暴咳者，为濒死。
杂病饥而不能食者有二道∶其人虽饥，闻食臭忽恶之者，虫也；但饥而不能食者， 瘕
也。
痿与痹易混，而详之，则痹者，主皮肤不仁；痿者，主筋骨萎软。
风邪难愈，或虽瘥复发者，不必服风药，唯以助阳气散风邪为要。
病阳虚者易治，阴虚者难治，何者？阴虚则阳益虚，如虚劳是也。故阴虚火动者，虽能
食遂
至死。阳虚者，脉不数而食减，是以多肉脱。故主饵食，禁灸。灸之则反脉为数，其为害亦
不鲜矣。
虚劳脉细数者，脉乍见和平，则为近死期。易所谓枯杨生华，何可久也？虽缓者，不出
五七日而死。
一夫病似狂，恐惧恶见人，闭居陋室半年所，后神气渐爽，而手足拘挛，舌强直难语言
，心
下如板筑， 癖妨胀。因灸脊际，服熊胆，病颇愈。盖此证癖气妨胀，故不发狂。若癖气内
攻，则精神失职，必发狂。今不然，故免此患也。
妇人脐下及任脉有块者，不孕。凡 癖所在，阳气必不行，故以艾灸资阳气为可。
父母有癖气者，其子必受之，犹如霉癞之系遗毒也。
霉毒入眼者，其始必头痛也。
诸出血后血气未复，犯风寒，则多成痨。假令不成痨，证候错杂，难遽愈。
一男子素有癖气，偶感邪气，其热炽盛，谵语烦乱。医治之，热颇解，但心下冲逆
，大
便秘，元气虚惫，数日不能复。余诊之曰∶癖气耳，莫为意。因使绝药，治专饵食，而精气
渐复，大便快通，全愈。此证虽元气惫，幸大便秘结，故知病可愈也。
喘哮下部肉脱者，属癖气。凡癖气逆上者，多下部肉脱。
其人脉数，腹气不和者，为中风兆，宜速灸。若缓漫经日，则因伤食，外感忽发中风也
。
霉毒脉数咳嗽，与劳相似，但霉毒不肉脱，大便秘结，小便淋涩。如劳，虽小便浊，不
淋涩
，且肉脱或下利也。若霉毒下利者，在病末殆为凶候。(按霉毒咳嗽似虚劳者，霉疠新书栝
蒌汤能治之。)
诸病将死时，多见厥阴证，是必然理，不止伤寒也。
火动证病未发喘者，系下元失守，为难救。
喘哮甚者，与香效木、沉香亦可。仲景专用浓朴、杏子，此系无癖气者之治。在今世则
多
属癖气，故沉香、木香奏效也。余为制一方，茯苓、枳实、半夏、干姜、木香，共五味。
郁证与痨相似，但痨脉微细数，郁脉多沉，或虽见他脉，未曾至微细，是为辨也。
痨之极，有便蛔虫者，有下肠垢者，皆为濒死候。凡旧病羸劣吐下蛔者，皆濒死候。不
止痨也，仲师厥阴所论为有旨。
劳发白疹者，多在胸膈而不在面部，此热气熏蒸，津液外泄也。其理与元气衰卫气失守
绝
汗者，同为恶候。伤寒发白 者，邪气从 而解也，故为善候。然宜与他证并看而决之。
蓄水者，阳气郁于中焦，上下不相和，故发烦渴，如五苓散证是也。
狂证以白虎汤治其里，以艾灸治其外者，此白虎消肠胃之郁热，艾灸散荣卫之郁滞，即
寒热
并施，内外兼攻之妙用也。(狂症者，灸心俞、患门、三里数万壮得效。《扁鹊心书》云∶
一人得风狂已五年，时止，百方不效。余为灌睡圣散三钱，先灸巨阙五十壮，醒时再服，又
灸心俞五十壮，服镇心丹一料。余曰∶病患已久，须大发一回方愈，后果大发，一日全好，
是亦同揆。)
霉毒壅塞经络者，患疟或痢之日，善驱除其邪气，则宿毒并去也。如他痼疾亦然。
妊娠与血块易混。然血块者顽固沉着，无发扬之势。妊娠者，凝结温然，有润泽之气。
又讯
之于妇人夜阴快寝后，小腹勃然突起者，娠也。又乳头黑者娠也。(妇人经闭者∶乳头多黑
，故难一定。贺川氏《产论翼》有详说，宜并考。)
后世以黄花、人参、为补涩邪气，误矣。今痈疽痘毒专用黄 者，其毒自里达表也。人
参亦同。(古方用黄 主表达非补气，人参亦主滋津，故柴胡泻心方中用之无嫌也。)
本邦人性刚悍，不喜甘味，若强食之，则泥恋生气滞。西人性柔弱，喜甘味，故药方甘
草分
量每过于邦人。譬之于病患犹元气虚者，虽服人参多量不泥，在壮实者忽生闷也。昔者今大
路一溪翁悟此旨，专主顺气，常用香苏散，而至甘草不用，匙以指头排散少许尔。(按香川
修德顺气说。世以艮山先生为滥觞，殊不知先生实本于一溪氏也。盖当时升平已久，浩然气
皆馁，于是有顺气之说。盖万 以根于气也。)
求嗣法以温腰为主。故灸腰眼穴效，浴温泉亦效。
妇人有血块者，虽怀孕，临产时或难分娩。(拙轩曰∶一种有横骨狭隘害分娩者，非手
术则不得治，不可有知。)
一妇人腹痛在脐上一寸许，按之惕然彻痛，脉数，乃断为内痈。饵以鸡蛋，服以黄 、
薏苡剂，后十日，大便果下脓血。
暑邪概自汗出，故难有表证，不枵发汗剂，与白虎汤类可。
狂证在妇人难治，霉毒在妇人易治。(妇人因瘀血发狂者易治，在男子发狂虽轻者不易
治。)
四苓散加汉苍术治雀目屡效。雀目多属疳，因治疳方中多用此品，亦能奏效。(拙轩曰
∶《眼科提要》云∶四苓散加苍术，更加夏枯草一味，治晚盲极效。)
戢菜能治结毒骨节痛，但其臭恶不易多服耳。
余每称心小胆大之语，以为医家吃紧。(先生之术，固创出前贤。然先根底医经经方，
而复
致力于思邈诸子。故其于大疾沉 ，自然游刃有余矣。)(拙轩曰∶读此条，可谓名下无虚
士也。)
黄连性燥，虽浸水出之必干。黄芩性润，虽去水犹湿。故知芩连同治痢而各异性也，治
呕亦然。
诸疮内攻为水气者，与赤小豆汤。热甚者，与大连翘汤效。
病患虚里动甚者，多遗精。(陈修园以龙胆泻肝汤治梦泄，曰以肝实而火盛也。沈芊绿
曰∶当先治其心火而及其余，宜黄连清心饮，亦与此说相发。)
大病后表气薄弱者，偶感风冷则卒厥，此虽在夏月，属中寒也。(李挺曰∶中寒冬夏同
有之，旨矣哉。)(拙轩曰∶与古人霍乱四时有之云者同。案俱皆理到此言，足互发明。)
疟与痢同因而异其位∶疟邪在表里间，而痢邪即着肠胃。故疟在外易治，痢在里难解也
。(《医说》云∶暑毒在脾，湿气连脚，不泄则痢，不痢则疟。而艮山能发其理。)
噤口痢者，毒瓦斯剧甚，自肠中熏蒸胃口也，急与承气汤下之为得矣。若失下，腹濡口噤
者，宜独参汤。
膈、噎、反胃、三者，同病也。但反胃者，胃中不和，饮食难化，或朝食暮吐。膈噎者
，胃管萎HT 无润，谷气不能下，或 癖壅闭胃口，饮食为之妨害。故反胃反在壮年，而膈噎多属
其人屡患喉痹者，多为膈噎，此因喉痹气管耗损，津液失润泽也。壮年者可治，在老人
难治，何则？胃气衰弱，胃管硬强，譬之革囊，犹水渍火焦，则缩不能容物也。
膈噎与鼓胀同因属 癖也。癖气横梁，腹皮为之膨胀者，鼓也。癖气潜匿，腹皮为之陷
没者，膈也。二病俱系精气不振，腹里失润泽也。
凡长病面部肿气俄减者，阳气下陷也，不可忽诸。
其人气血凝结，腹里生郁热，水谷之气渐蚀以为羸瘦者，名曰劳瘵。此不必虚乏人，虽
壮实者往往有之。
喘急有因奔豚者，此癖气上侵心肺也。(按三因息奔汤能治此证。)
喘家其证虽剧。甚多无害于性命。若伤寒卒中诸急病，或缓病咳忽止但喘者，有不测之
变，不可轻忽也。
积年苦头痛者，多属癖气，如偏头痛尤然。故癖气在右则右痛，在左则左痛也。
丹波一妇人患腰痛三年不愈，食干过腊鱼有效。(按恐是血沥腰症，花冈青洲治痿证，
亦用干过腊鱼末，宜试。)
痛风与香港脚同因。而痛风其邪浅，香港脚其邪深，故其愈亦有迟速之别也。
方今所行香港脚，即《千金》、《外台》所谓风毒香港脚也。宋元以来所谓香港脚，即今所行
疝气
也。(后藤徽曰∶吾邦往昔风毒香港脚消熄无行，宝历以来，流行复煽，是以先子有此说。)
中风偏枯，多因癖气壅塞经络，气不能外达。故癖气在右则右枯，在左则左枯也。
中风口眼 斜者，因正邪分争之势而血气偏胜也。故 斜在右则病则左， 斜在左则病
在右也，如半身痹痿者，亦同此理。
我年少时阅读先哲的理疗书籍，私下认为它们要么粗疏鲁莽，要么过于细密繁琐，与我的见解不合，所以没有读完就放下了。于是转而专攻张仲景的经典著作，一心钻研，略微窥探到著述的宗旨，又向当时的医术实践去验证。经过几十年的努力，后来才阅读各家之书，才知道先哲有独到的高超本领，后悔当初没有虚心深思。从此继续探寻推究，要到达古人的境界也不难了。可惜时日已晚，路途遥远，不再能与他们比肩，成就一家之言。然而也不能自我停止，姑且记录其中的一二，作为后生晚辈领悟参考的资料。
近代研究古方的学问，以名古屋玄医和河天民为杰出代表，但未免带有金元时期的陋习。到了艮山先生，豪迈地崛起，彻底洗刷了以前的弊病风气。他的见识和理疗方法，必定有与前人截然不同的地方，世人认为他好奇（标新立异）是不对的。大概我们的医术传到一溪、道三这一派门下时，流散破碎到了极点。所以享元时期的医人又重新转向复古，这也是自然的趋势。（拙轩说：《伤风约言》一部书，是先生的本领所在，可以说是善于读《伤寒论》的人。后来的豪杰辈出，都是闻听先生的风范而兴起的，这是我国医学的中兴。先生起笔于此，并非偶然。）
谷肉果菜，是正性（平和之性）。草木虫石，是偏性（猛烈之性）。所以古代用正性来养精，用偏性来治病。后人不知道这个意义，打算用药品来补精气，这也错了。（《素问》说：五谷为养，五果为助，五菜为充，毒药攻邪，这就是医家的总纲领。先生早就标举出来，作为日后东洞等人的立论蓝本。）
乱世中人的气质剽悍，肝胆气郁结较少。治世中人的气质游惰，肝胆气郁结较多。所以适宜用熊胆来开通郁结，使肝胆之气通达。（永富凤说：我在都市市井之人身上验证过，比比皆是。大概太平日子久了，百姓繁衍，金钱虚耗，奢侈淫佚日益盛行，那么聪明机智的人不免得气势病。医人在施治时从这方面下功夫，就有大裨益了。）
那人如果有癖积（腹内结块或积聚之气）而饮食减少的，好比人家走廊倒塌厢房破败，厅堂逐渐狭小一样。所以不除去癖积，胃就不能振奋。医生不知道这个道理，想用毒药补胃气，并且轻视饮食，进一步损耗精液的，不是太荒谬了吗。凡是治疗这种病症，先驱除癖积，以滋味养胃气为主。痈疽服用鸡肉或鸡蛋，能托出毒气。优于人参，所以治疗疮疡以食用鸡肉鸡蛋为专一。（徐灵胎说：服药原本是为了治病而设，并不是借以生长气血。大概是同样的见解。）
外感病以汤药为主，内伤病以食物为主，搞错了就无法得到正确的治疗。
赤蛙不仅能治小儿癫痫，也能治大人虚劳，大概癫痫和虚劳都属于癖积一类。此品能治疗癖气，妨害脾胃导致下利的情况，兼能制约蛔虫。（杨氏《直指》曾氏《口议》都说：十五岁以下为疳，十五岁以上为瘵，很与此说吻合。而这两人只用固阳滋阴的药剂，更没有发明。艮山特别用行血荡气的药，来除去腹里的癖积，其医术高出一等。）
癫痫下利者，吃鳗鲡烤干后服用是可以的。
按压腹部从心下到脐部，任脉突起的，是因为病气聚在脉下。病气不聚集的，脉不必突起。老人肌肉消瘦出现此证的，是接近死期的征兆。
按压腹部心下任脉左右充满有力的属于实证，如果濡弱不充满的属于虚证。
虚惫症，嘴唇颜色不淡白的，耳叶没有萎缩的，可以救活。应当仔细考察。
阳气浮泛的人，难以辨认肌肉消瘦的征候。先诊察背部，那人经常咳嗽或气喘，背上陷下的，是因为气逆见到脱肉的痕迹。此证属于气胀，所以名叫虚浮，不一定是水气。
诊察病人应当先审问是否曾患梅毒，为什么呢？现在梅毒浸淫筋骨，多是元气为之壅塞的缘故。
病重到大患目不瞬眼的，是眼胞元气脱失。这是反目，兆示接近死期。
凡是疼痛的，脉多紧弦，像太阳病头痛的就是这样。动脉与紧脉看似相反，而紧弦脉，是动脉的剧烈表现。动脉变为迟脉的，是正气弛缓而邪气未除，如结胸脉迟就是这样。大概动脉变迟的可以救，不变而数脉的就危险了。
黄疸未发作前出现腹痛的，多属于癖积，又有脾脏郁结导致腹痛的可辨别。（《金匮》说：谷气不消，胃中苦浊，这就是湿热导致腹痛。又说：诸黄腹痛而呕者，宜柴胡汤。这是黄疸腹痛的治疗方法。）
噎膈一旦进食的，不可放纵大吃，那人原本胃中虚竭，反而招致危害。
突然中风，多是癖积堵塞心窍，所以人事不省，不能活。如果不堵塞心窍的，半身不遂，或者口眼歪斜。虽然人事不省，但六脉相应，手足厥冷的，一身大气犹存，可以救活。
男女都年轻体壮却身体不舒服的，多是风寒，适宜调护。如果拖延经日，就会大便溏泄，以至重症，所以此证大便秘结为佳，溏泄为恶。
专门发出声音的多吐血，而脉不数，这不足为惧。真正吐血的，其脉必数急，这是大可恐惧的。
凡病不论六淫七情饮食男女，都是因为一气元气郁滞。所以皮肤郁滞的，经络滞涩的，随即都会波及腹里，就像水汇聚到低洼处，医者先得其大纲进行治疗是关键。
梅毒沉滞骨节的，经络壅塞尤其严重，所以发生种种变证。不可不知道。
那人虚弱咳嗽久不止的，这是由于寒气壅塞体表，与虚火扇动肺脏，所以咳越厉害，而肺越干枯。
奔豚证有肝气兼梅毒的，有肝气带疝气的，但梅毒与疝气本身不为奔豚。古语说：诸风掉眩属肝，就是这个道理。
痉及痱之类，身体不自由的，如果健啖但不运动，脾气就不能运行，所以四五年后必死。患此证的人，务必运动，以运行脾气，或许能终其天年。名古屋玄医曾患此病，善于保全始终，可以证明这一点。
水肿咳嗽严重的，一定是水气辐凑上部。又是水气引发暴咳的，是濒死之兆。
杂病饥饿但不能进食的有两种情况：那人虽然饿，闻到食物的气味忽然厌恶的，是有虫；只是饿而不能吃的，是瘕积。
痿证与痹证容易混淆，但详细分辨，则痹证，主要主皮肤麻木不仁；痿证，主要主筋骨萎软。
风邪难愈，或者虽然痊愈又复发的，不必服风药，唯有帮助阳气散风邪是关键。
阳虚病易治，阴虚病难治，为什么？阴虚则阳更虚，如虚劳就是这样。所以阴虚火动的，虽然能吃最终至死。阳虚的，脉不数而食减，因此多肉消瘦。所以主张吃食物，禁止灸法。灸了反而脉变数，其危害也不少。
虚劳脉细数的，脉忽然见和平，则是接近死期。《易经》所谓枯杨生华，怎么能长久呢？即使缓慢的，不出五七日而死。
一个男子病似狂，恐惧厌恶见人，闭门居住在陋室半年多，后来神气渐渐清爽，但手足拘挛，舌强直难语言，心下如板筑（坚硬），癖积妨碍胀满。因为灸脊际，服熊胆，病颇好。大概此证癖积妨碍胀满，所以不发狂。若癖积内攻，则精神失职，必发狂。现在不是这样，所以免除此患。
妇人脐下及任脉有块的，不孕。凡癖积所在，阳气必不行，所以用艾灸资助阳气是可以的。
父母有癖积的，其子必受之，犹如梅毒癞疾系遗传毒也。
各种出血后血气未恢复，犯风寒，则多成虚劳。假令不成虚劳，证候错杂，难迅速痊愈。
一个男子素有癖积，偶感邪气，其热炽盛，谵语烦乱。医治他，热颇解，但心下冲逆，大便秘，元气虚惫，数日不能恢复。我诊察他说：是癖积罢了，不要在意。于是让他停绝药物，治疗专心靠食物，而精气渐渐恢复，大便快通，全愈。此证虽元气惫，幸大便秘结，所以知病可愈。
喘哮下部肌肉消瘦的，属于癖积。凡癖积逆上的，多下部肌肉消瘦。
那人的脉数，腹气不和的，是中风的预兆，宜速灸。如果拖延经日，则因伤食，外感忽发中风。
梅毒脉数咳嗽，与虚劳相似，但梅毒不肌肉消瘦，大便秘结，小便淋涩。如虚劳，虽小便浊，不淋涩，且肌肉消瘦或下利。若梅毒下利的，在病末殆为凶候。（按梅毒咳嗽似虚劳的，梅毒新书栝蒙汤能治它。）
各种病将死时，多见厥阴证，是必然的道理，不止伤寒。
火动证病未发喘的，系下元失守，为难救。
喘哮严重的，与香效木、沉香也可以。仲景专用浓朴、杏子，这是无癖积者的治疗。在当今世则多属癖积，所以沉香、木香奏效。我为此制一方，茯苓、枳实、半夏、干姜、木香，共五味。
郁证与虚劳相似，但虚劳脉微细数，郁证脉多沉，或虽见他脉，未曾至微细，这是辨别点。
虚劳至极，有便蛔虫的，有下肠垢的，皆为濒死候。凡旧病羸劣吐下蛔的，皆濒死候。不止虚劳，仲师厥阴所论为有旨意。
虚劳发白疹的，多在胸膈而不在面部，此热气熏蒸，津液外泄也。其理与元气衰卫气失守绝汗的，同为恶候。伤寒发白疹的，邪气从腠理而解也，故为善候。然宜与他证并看而决之。
蓄水者，阳气郁于中焦，上下不相和，故发烦渴，如五苓散证就是。
狂证以白虎汤治其里，以艾灸治其外的，此白虎消肠胃之郁热，艾灸散荣卫之郁滞，即寒热并施，内外兼攻的妙用。（狂症者，灸心俞、患门、三里数万壮得效。《扁鹊心书》说：一人得风狂已五年，时止，百方不效。我为灌睡圣散三钱，先灸巨阙五十壮，醒时再服，又灸心俞五十壮，服镇心丹一料。我说：病患已久，须大发一回方愈，后果大发，一日全好，也是同理。）
梅毒壅塞经络的，患疟或痢的日子，善驱除其邪气，则宿毒并去也。如其他痼疾亦然。
妊娠与血块易混。但血块者顽固沉着，无发扬之势。妊娠者，凝结温然，有润泽之气。又讯之于妇人夜阴快寝后，小腹勃然突起者，娠也。又乳头黑者娠也。（妇人经闭者：乳头多黑，故难一定。贺川氏《产论翼》有详说，宜并考。）
后世以黄花、人参，为补涩邪气，误矣。今痈疽痘毒专用黄花的，其毒自里达表也。人参亦同。（古方用黄花主表达非补气，人参亦主滋津，故柴胡泻心方中用之无嫌也。）
本邦人性刚悍，不喜甘味，若强食之，则泥恋生气滞。西人性柔弱，喜甘味，故药方甘草分量每过于邦人。譬之于病患犹元气虚者，虽服人参多量不泥，在壮实者忽生闷也。昔者今大路一溪翁悟此旨，专主顺气，常用香苏散，而至甘草不用，匙以指头排散少许尔。（按香川修德顺气说。世以艮山先生为滥觞，殊不知先生实本于一溪氏也。盖当时升平已久，浩然气皆馁，于是有顺气之说。盖万病以根于气也。）
求嗣法以温腰为主。故灸腰眼穴效，浴温泉亦效。
妇人有血块的，虽怀孕，临产时或难分娩。（拙轩说：一种有横骨狭隘害分娩的，非手术则不得治，不可不知。）
一个妇人腹痛在脐上一寸许，按之惕然彻痛，脉数，乃断为内痈。饵以鸡蛋，服以黄花、薏苡剂，后十日，大便果下脓血。
狂证在妇人难治，梅毒在妇人易治。（妇人因瘀血发狂者易治，在男子发狂虽轻者不易治。）
四苓散加汉苍术治雀目屡效。雀目多属疳，因治疳方中多用此品，亦能奏效。（拙轩说：《眼科提要》说：四苓散加苍术，更加夏枯草一味，治晚盲极效。）
我常称心小胆大之语，以为医家吃紧。（先生的医术，固创出前贤。然先根底医经经方，而复致力于思邈诸子。故其于大疾沉疴，自然游刃有余矣。）（拙轩说：读此条，可谓名下无虚士也。）
黄连性燥，虽浸水出之必干。黄芩性润，虽去水犹湿。故知芩连同治痢而各异性也，治呕亦然。
病患虚里动甚的，多遗精。（陈修园以龙胆泻肝汤治梦泄，曰以肝实而火盛也。沈芊绿说：当先治其心火而及其余，宜黄连清心饮，亦与此说相发。）
大病后表气薄弱者，偶感风冷则卒厥，此虽在夏月，属中寒也。（李挺说：中寒冬夏同有之，旨矣哉。）（拙轩说：与古人霍乱四时有之云者同。案俱皆理到此言，足互发明。）
疟与痢同因而异其位：疟邪在表里间，而痢邪即着肠胃。故疟在外易治，痢在里难解也。（《医说》说：暑毒在脾，湿气连脚，不泄则痢，不痢则疟。而艮山能发其理。）
噤口痢者，毒瓦斯剧甚，自肠中熏蒸胃口也，急与承气汤下之为得矣。若失下，腹濡口噤的，宜独参汤。
膈、噎、反胃，三者，同病也。但反胃者，胃中不和，饮食难化，或朝食暮吐。膈噎者，胃管萎弱无润，谷气不能下，或癖积壅闭胃口，饮食为之妨害。故反胃反在壮年，而膈噎多属其人屡患喉痹的，多为膈噎，此因喉痹气管耗损，津液失润泽也。壮年者可治，在老人难治，为什么？胃气衰弱，胃管硬强，譬之革囊，犹水渍火焦，则缩不能容物也。
膈噎与鼓胀同因属癖积也。癖积横梁，腹皮为之膨胀的，鼓也。癖积潜匿，腹皮为之陷没的，膈也。二病俱系精气不振，腹里失润泽也。
凡长病面部肿气俄减的，阳气下陷也，不可忽诸。
其人气血凝结，腹里生郁热，水谷之气渐蚀以为羸瘦的，名曰劳瘵。此不必虚乏人，虽壮实者往往有之。
喘急有因奔豚的，此癖积上侵心肺也。（按三因息奔汤能治此证。）
喘家其证虽剧。甚多无害于性命。若伤寒卒中诸急病，或缓病咳忽止但喘的，有不测之变，不可轻忽也。

When I was young, I read the therapeutic books of the sages. Privately, I thought they were either too rough and crude or overly detailed and dense, which did not align with my own views, so I did not finish reading them. Therefore, I took the classics of Master Zhong (Zhang Zhongjing) and focused entirely on studying them. I briefly glimpsed the intent of their compositions and verified them through medical practice. After decades, when I finally read the works of various schools, I realized that the sages possessed unique and superior skills. I regretted not being humble and contemplative at that time. From then on, by continuing to explore and deduce, reaching the realm of the ancients was not difficult. Alas, the sun is setting and the road is long; I can no longer keep pace with them to establish my own school. However, I cannot stop myself. I will tentatively record a few points here as a resource for the understanding of younger generations.
In recent times, the study of ancient prescriptions has been led by Nagoya Gen'i and Kawam Tenmin, but they inevitably retained the bad habits of the Jin-Yuan period. It was Mr. Gensan who heroically rose up, thoroughly washing away the previous弊端 (malpractices). His insights and therapeutic methods must have been significantly different from his predecessors. The world considers him curious (novelty-seeking), which is incorrect. Generally speaking, our medical arts had become fragmented and extremely depleted by the time they reached the lineage of Yixi and Daosan. Thus, it was natural for physicians in the Gen'yo era to turn back to antiquity. (Zhuoxuan said: "The entire work *Shangfeng Yueyan* reflects Mr.'s core competence; he can be called one who truly understands the *Shanghan Lun*. Later heroes emerged, inspired by his demeanor; this marks the revival of our path. Mr.'s starting point here was not accidental.")
Grains, meats, fruits, and vegetables possess "correct nature" (balanced properties). Herbs, trees, insects, and minerals possess "deviant nature" (potent/strong properties). Therefore, in ancient times, correct nature was used to nourish essence, while deviant nature was used to treat disease. Later generations did not understand this principle and attempted to use medicines to tonify essence and qi, which was a mistake. (*Suwen* states: "Five grains for nourishment, five fruits for assistance, five vegetables for supplementation; toxic substances attack pathogens." This is the general guideline for physicians. Mr. highlighted this early on, laying the foundation for later arguments by Dongdong and others.)
In chaotic times, people's temperament is fierce and rash, with less liver-gallbladder qi stagnation. In peaceful times, people's temperament is idle and sluggish, with more liver-gallbladder qi stagnation. Therefore, it is appropriate to use bear gallbladder to open stagnation and allow liver-gallbladder qi to flow freely. (Yongfu Feng said: "I have verified this among people in cities and markets; it is ubiquitous. Perhaps due to long periods of peace, population growth, financial waste, and increasing luxury, intelligent people inevitably suffer from 'qi momentum' diseases. Physicians who work on this aspect during treatment will gain great benefit.")
If a person has *pi* (accumulations/masses) and reduced appetite, it is like a house where corridors collapse and side rooms decay, causing the main hall to gradually shrink. If *pi* is not removed, the stomach cannot revitalize. Doctors who do not understand this logic and attempt to tonify stomach qi with toxic drugs, while neglecting diet and further damaging essence and fluids, are acting absurdly. To treat such conditions, one must first expel *pi*, focusing primarily on nourishing stomach qi with flavorful foods. For carbuncles and sores, consuming chicken meat or eggs can help push out toxins. This is superior to Ginseng; thus, treating sores should focus on dietary intake. (Xu Lingtai said: "Medicines are prescribed to treat disease, not to generate blood and qi. This seems to share the same insight.")
Exogenous diseases should be treated mainly with decoctions, while endogenous injuries should be treated mainly with food. Confusing the two leads to ineffective treatment.
Red frogs can treat not only pediatric epilepsy but also adult consumptive diseases. Epilepsy and consumptive diseases both belong to the category of *pi*. This substance treats *qi* accumulation that damages the spleen and stomach, leading to diarrhea, and also controls roundworms. (Yang's *Zhizhi* and Zeng's *Kouyi* state: "Under fifteen years old is *gan*; over fifteen is *zai*. This aligns well with this theory. However, these two scholars only used agents to consolidate yang and nourish yin, without further innovation. Gensan specifically used blood-moving and qi-stirring herbs to remove abdominal *pi*, demonstrating superior skill.")
For epilepsy with diarrhea, eating dried eel is effective.
Pressing the abdomen from the epigastrium to the umbilicus: if the Ren Mai protrudes, it is because pathological factors are gathering below the pulse. If pathological factors are not gathered, the pulse does not need to protrude. In elderly people, muscle wasting presenting with this sign indicates proximity to death.
Pressing the epigastrium along the Ren Mai: if full and forceful on both sides, it is excess; if soft, weak, and not full, it is deficiency.
In cases of extreme deficiency and exhaustion, if the lips are not pale white and the earlobes have not atrophied, recovery is possible. This requires careful observation.
When yang qi floats superficially, it is difficult to recognize signs of muscle wasting. First examine the back. If the person frequently coughs or wheezes and the back is depressed, it is due to rebellious qi manifesting as muscle wasting. This condition belongs to qi distension, hence named "deficiency floating," and is not necessarily water retention.
When examining patients, one should first inquire about a history of syphilis. Why? Because modern syphilis invades bones and joints, often blocking primordial qi.
In severe illness, if the eyes do not blink, it indicates depletion of yuan qi in the eyelids. This is "reversed eyes," a sign of impending death.
Diseases that develop gradually are often difficult to treat. Muscle wasting or water retention indicates untreatability.
Painful conditions usually present with tight or wiry pulses, similar to headache in Taiyang disease. The moving pulse and tight pulse seem opposite, but a tight-wiry pulse is an intensified form of the moving pulse. If a moving pulse changes to a slow pulse, it indicates slackening of righteous qi and persistence of pathogenic qi, as seen in chest binding with a slow pulse. Generally, a moving pulse changing to slow is salvageable; if it remains fast, it is dangerous.
Abdominal pain before the onset of jaundice often belongs to *pi*. Spleen qi stagnation causing abdominal pain can be distinguished. (*Jingui* states: "Grain qi fails to digest, causing turbidity in the stomach; this is why damp-heat causes abdominal pain." It also says: "For all jaundice with abdominal pain and vomiting, Chaihu Tang is suitable." This outlines the treatment for jaundice-related abdominal pain.)
For dysphagia where food enters suddenly, one should not eat excessively. The person's stomach is originally empty and deficient; overeating will cause harm.
Sudden stroke is often caused by *pi* blocking the heart orifice, leading to unconsciousness and death. If the heart orifice is not blocked, there may be hemiplegia or facial deviation. Even if unconscious, if the six pulses correspond and hands/feet are cold, the great qi of the body still exists, and rescue is possible.
Young men and women who are not yet fully mature but feel unwell often suffer from wind-cold and require care. If neglected for days, stool becomes loose, leading to severe illness. Therefore, constipation is good for this condition, while diarrhea is bad.
Those who make specific sounds often vomit blood, but if the pulse is not rapid, it is not frightening. True hematemesis presents with a rapid and urgent pulse, which is highly alarming.
All diseases, whether caused by the six exogenous factors, seven emotions, diet, or sexual activity, stem from the stagnation of primordial qi. Stagnation in the skin and meridians eventually affects the interior, like water flowing into lowlands. Physicians must grasp the general principle for treatment.
Syphilis stagnant in bone joints causes severe meridian blockage, leading to various complications. This must be known.
Weak individuals with chronic coughing suffer from cold qi blocking the exterior and deficient fire fanning the lungs, worsening the cough and drying the lungs.
Ben-tun syndrome may involve liver qi combined with syphilis, or liver qi with hernia. However, syphilis and hernia themselves do not constitute Ben-tun. As the ancient saying goes: "All wind, tremors, and dizziness belong to the Liver."
Conditions like spasm and fei (paralysis) involving immobility of the body will lead to death within four to five years if the patient eats well but does not exercise, as spleen qi cannot circulate. Patients should exercise to move spleen qi to fulfill their natural lifespan. Nagoya Gen'i suffered from this and managed to survive until old age through proper care, proving this point.
Severe edema and cough indicate water qi gathering in the upper body. Sudden violent cough due to water qi indicates imminent death.
Miscellaneous diseases involving hunger but inability to eat have two causes: if the person feels hungry but suddenly dislikes the smell of food, it is due to parasites; if simply hungry but unable to eat, it is due to *jia* masses.
Wei (flaccidity) and Bi (impediment) are easily confused. Bi primarily involves numbness of the skin; Wei primarily involves flaccidity of sinews and bones.
Wind pathogens are hard to cure. Recurrence after recovery does not necessarily require wind-dispelling herbs; assisting yang qi to disperse wind is key.
Yang deficiency diseases are easier to treat; yin deficiency diseases are harder. Why? Yin deficiency leads to further yang deficiency, as seen in consumption. Thus, yin deficiency with fire hyperactivity, even with good appetite, leads to death. Yang deficiency presents with non-rapid pulse and poor appetite, leading to muscle wasting. Treatment focuses on diet; moxibustion is prohibited. Moxibustion may cause the pulse to become rapid, causing harm.
In consumption with fine and rapid pulses, if the pulse suddenly appears calm, it indicates approaching death. As the *I Ching* says: "Withered poplar blooms; how can it last?" Even if slow, death occurs within five to seven days.
A man exhibited symptoms resembling madness, fearing and avoiding people, living in a dark room for half a year. Later, his spirit cleared, but he developed limb spasms, stiff tongue, difficulty speaking, hardness in the epigastrium, and distension due to *pi*. He was treated with moxibustion on the spine and bear gallbladder, and improved significantly. This condition involves *pi* obstructing distension, preventing madness. If *pi* attacked internally, mental function would fail, causing madness. Since this did not happen, he avoided this complication.
Women with masses below the navel and along the Ren Mai are infertile. Wherever *pi* exists, yang qi cannot flow; thus, moxibustion to support yang qi is advisable.
Children of parents with *pi* will inherit it, similar to the transmission of syphilis or leprosy.
Syphilis entering the eyes initially causes headache.
After bleeding, if wind-cold is contracted before blood and qi recover, it often leads to consumption. Even if consumption does not develop, mixed symptoms make quick recovery difficult.
A man with existing *pi* contracted pathogenic qi, resulting in high fever, delirium, and agitation. Treatment reduced the fever, but he experienced epigastric rebellion, constipation, and extreme weakness, failing to recover for days. I diagnosed it as *pi* and advised stopping medication, focusing solely on diet. Essence and qi gradually recovered, bowel movements normalized, and he healed completely. Although qi was exhausted, constipation indicated recoverability.
Wheezing with lower body muscle wasting belongs to *pi*. When *pi* rebels upward, lower body muscle wasting is common.
Rapid pulse with disharmonious abdominal qi indicates an impending stroke; moxibustion should be applied quickly. Delay allows food stagnation and external contraction to trigger sudden stroke.
Syphilis with rapid pulse and cough resembles consumption, but syphilis lacks muscle wasting, features constipation, and painful urination. Consumption may have turbid urine without pain, plus muscle wasting or diarrhea. Syphilis with diarrhea near the end of the disease is a ominous sign. (Note: *Meili Xinshu* suggests Gualou Tang for syphilis cough resembling consumption.)
At the point of death, various diseases often show Jueyin syndrome patterns; this is inevitable, not limited to Shanghan.
Fire hyperactivity without asthma indicates failure of the lower origin, making it difficult to save.
Severe asthma may respond to Xiangxiaomu and Chenxiang. Zhang Zhongjing used Houpo and Xingzi exclusively, suitable for those without *pi*. In modern times, most cases involve *pi*, so Chenxiang and Muxiang are effective. I formulated a prescription: Poria, Immature Bitter Orange, Pinellia, Dried Ginger, and Costus root (5 ingredients).
Yu syndrome resembles consumption. Consumption presents with faint, fine, rapid pulses; Yu syndrome presents with deep pulses, or other pulses but never faint/fine. This distinguishes them.
Extreme consumption may present with passing roundworms or intestinal mucus, indicating imminent death. Chronic emaciation with vomiting/passing worms also indicates imminent death. This applies beyond consumption; the Jueyin discussions in Master Zhong's work hold significance.
White rashes in consumption appear mostly on the chest and diaphragm, not the face, due to heat steaming and fluid leakage. This mechanism is similar to critical sweating due to衰竭 of primordial qi and loss of defensive qi, both being ominous signs. White rashes in Shanghan indicate pathogen exiting through pores, a good sign. However, judgment should be made considering other symptoms.
Water retention results from yang qi stagnating in the middle jiao, causing disharmony between upper and lower, leading to irritability and thirst, as seen in Wuling San syndrome.
Madness treated internally with Baihu Tang and externally with moxibustion utilizes Baihu to clear gastrointestinal heat and moxibustion to disperse nutritive-defensive stagnation. This combines cold and heat therapies, attacking internally and externally. (Moxibustion on Xinshu, Hunmen, and Zusanli with thousands of moxa cones is effective. *Bianque Xinshu* records a case of five-year wind-madness cured by Shuisheng San, moxibustion on Juque and Xinshu, and Zhenxin Dan. The patient required a severe flare-up to heal, confirming this approach.)
Syphilis blocking meridians can be expelled during malaria or dysentery episodes by driving out pathogenic qi, removing old toxins. The same applies to other chronic diseases.
Pregnancy is easily confused with blood masses. Blood masses are stubborn and settled, lacking expansion. Pregnancy is condensed and warm, with a moist quality. Also, if a woman's lower abdomen protrudes suddenly after sleeping at night, she is pregnant. Dark nipples also indicate pregnancy. (Amenorrhea often involves dark nipples, making diagnosis difficult. Hechuan's *Chanlun Yi* provides detailed explanations for reference.)
Later generations mistakenly believed Huangqi and Ginseng trap pathogens. Today, Huangqi is used specifically for carbuncles and smallpox toxins to draw toxins from inside to outside. Ginseng acts similarly. (Ancient formulas used Huangqi to express the exterior, not to tonify qi; Ginseng nourishes fluids. Thus, using them in Chaihu Xiexin Tang is acceptable.)
Our nation's people are strong-willed and dislike sweet tastes. Forcing sweet foods causes stagnation. Westerners are gentle and prefer sweet tastes, so herbal formulas contain more Licorice than ours. For patients, excessive Ginseng does not cause stagnation in the weak but causes oppression in the robust. Formerly, Yixi understood this, advocating qi smoothing with Xiangsu San, avoiding Licorice except for tiny amounts. (Xiangchuan Xiude's theory of qi smoothing. The world considers Gensan the originator, but he actually followed Yixi. Due to long peace, heroic qi became weak, leading to the theory of smoothing qi. All diseases root in qi.)
Methods for conception focus on warming the waist. Moxibustion on Yaoyan points and hot spring baths are effective.
Women with blood masses may have difficulty delivering even if pregnant. (Zhuoxuan noted: Narrow pelvic bones hinder delivery; surgery is required. This must be known.)
A woman had abdominal pain 1 cun above the navel, tender to touch, with a rapid pulse. Diagnosed as internal abscess. Treated with egg yolks and Huangqi/Yiyi decoction. Ten days later, pus and blood passed in stool.
Summerheat causes spontaneous sweating, making exterior syndromes rare. Do not use sweating agents; Baihu Tang type formulas are suitable.
Madness is harder to treat in women; syphilis is easier to treat in women. (Madness due to blood stasis is easier in women; even mild madness is hard to treat in men.)
Siling San plus Cangzhu is effective for night blindness. Night blindness often belongs to *gan*; since this herb is used in *gan* treatments, it works. (Zhuoxuan noted: *Yanke Tiyao* states adding Chukucao to Siling San + Cangzhu is very effective for late-onset blindness.)
Jicai treats syphilitic bone/joint pain, but its foul odor limits dosage.
I often emphasize "small heart, big courage" as crucial for physicians. (Mr.'s art innovated upon predecessors but rooted in classic texts and Sun Simiao's works. Thus, he handled major diseases with ease.) (Zhuoxuan said: "Reading this confirms his reputation is well-deserved.")
Coptis is dry; even soaked, it remains dry. Scutellaria is moist; even drained, it remains wet. Thus, although used together for dysentery, they differ in nature. This applies to treating vomiting as well.
Internal attacks of sores causing water retention are treated with Chixiaodou Tang. Severe heat responds to Dalianqiao Tang.
Hyperactive Xu Li (vital gate) often accompanies seminal emission. (Chen Xiuyuan used Longdan Xiegan Tang for nocturnal emission due to liver excess and fire. Shen Qianlü suggested treating heart fire first with Huanglian Qingxin Yin, complementing this view.)
After severe illness, weak exterior qi makes one susceptible to sudden syncope from wind-cold, even in summer. This is interior cold. (Li Ting noted: Interior cold occurs in winter and summer alike. This is profound. Zhuoxuan added: Similar to ancient views on Huoluan occurring in all seasons. These theories illuminate each other.)
Malaria and dysentery share causes but differ in location. Malaria pathogens are between exterior and interior; dysentery pathogens attach to intestines/stomach. Thus, malaria (exterior) is easier to treat; dysentery (interior) is harder to resolve. (*Yishuo* states: Summer toxin in spleen, dampness in legs; no diarrhea means dysentery, no dysentery means malaria. Gensan elucidated this principle.)
Anorexic dysentery involves severe toxins steaming from intestines to stomach. Rapid purgation with Chengqi Tang is appropriate. If purgation is missed and abdomen is soft with locked jaw, Dushen Tang is suitable.
Ge, Ye, and Fanwei are similar diseases. Fanwei involves stomach disharmony, difficult digestion, or morning food evening vomiting. Ge and Ye involve atrophic, dry esophagus, inability of grain qi to descend, or *pi* blocking the stomach entrance, hindering food intake. Fanwei often affects young adults; Ge and Ye often affect those with recurrent throat bi. Throat bi damages airways and fluids, leading to Ge/Ye. Treatable in youth; difficult in elderly due to weak stomach qi and hardened esophagus, like a leather bag shrunk by fire/water.
Ge/Ye and Drum Distension share causes related to *pi*. *Pi* obstructing beams causes abdominal distension (Drum); *pi* hiding causes abdominal depression (Ge/Ye). Both involve declining essence/qi and lack of moisture in the interior.
Long-term illness with sudden reduction of facial swelling indicates sinking of yang qi; do not ignore this.
Qi and blood coagulation generating interior heat, slowly consuming grain qi leading to emaciation, is named Laozhai. This affects not just the weak but also the robust.
Urgent breathing due to Ben-tun involves *pi* invading heart/lungs. (San Yin Xiben Tang treats this.)
Asthma sufferers, even with severe symptoms, often survive. However, sudden cessation of cough with persistent asthma in acute/exogenous diseases indicates unpredictable changes; do not neglect.
Chronic headaches often belong to *pi*, especially migraines. Right-sided *pi* causes right pain; left-sided causes left pain.
A woman from Tanbo had intractable lower back pain for three years; eating dried salted fish was effective. (Likely blood-stasis back pain. Hanaoka Seishu used dried fish powder for wei syndrome; worth trying.)
Gout and Hong Kong Foot (podagra) share causes. Gout pathogens are shallow; Hong Kong Foot pathogens are deep, affecting healing speed.
Modern Hong Kong Foot corresponds to Wind-Toxic Hong Kong Foot in *Qianjin* and *Waitai*. Song-Yuan era Hong Kong Foot corresponds to modern hernia. (Hou Teng Hui noted: Wind-toxic Hong Kong Foot disappeared in our country, revived post-Horeki era, explaining my father's statement.)
Stroke hemiplegia is often caused by *pi* blocking meridians, preventing qi extension. Right *pi* causes right paralysis; left *pi* causes left paralysis.
Facial deviation in stroke results from struggle between righteous and pathogenic qi, causing blood/qi imbalance. Deviation to the right implies pathology on the left, and vice versa. Same logic applies to hemiplegia.
