论四物、逍遥、六君、归脾、小柴胡、参苏。
补中益气、四君子诸汤加减法。
天师曰∶同治者，同是一方而同治数病也。如四物可治吐血，又可治下血；逍遥散可治木郁，
又可治数郁；六君子汤可治饮食之伤，又可治痰气之积。然而方虽同，而用之轻重有别，加减有殊，未
可执之以治一病，又即以治彼病耳。如吐血宜加麦冬、甘草，便血宜加地榆、黄芩之类于四物汤中也。
如丹皮、栀子，宜加于木郁之中，黄连宜加火郁之中，黄芩、苏叶宜加于金郁之中，石膏、知母宜加于土
郁之中，泽泻、猪苓宜加于水郁之中也。伤肉食，宜加山楂；伤米食，宜加麦芽、枳壳；伤面食；宜加
萝卜子之类于六君子汤内也。同治之法，可不审乎。
张公曰∶同治法不止三方，予再广之。归脾汤可治郁怒伤肝之人，又可治心虚不寐之症。小柴胡汤
可治伤风初起之病，又可和伤寒已坏之病。参苏饮可治风邪之侵，又可治气郁之闷。补中益气汤可升提
阳气，又可补益脾阴，兼且消食于初伤，祛邪于变后，疟症藉之以散邪，泻症资之以固脱也。四君子汤可
以补气之不足，又可以泻火之有余，诸如此类，不可枚举，亦在人善悟之耳。
华君曰∶余未传。
论中湿 论中暑 论中寒
天师曰∶异治者，一病而异治之也。如人病中湿也，或用开鬼门之法，或用泄净府之法是也。虽同
是水症，何以各施治法而皆效？盖开鬼门者，开人毫毛之孔窍也；泄净府者，泄大小之二便也。治法虽殊，
而理归一致。其一致何也？盖
水肿之症，原是土气之郁，土郁则水自壅滞而不流，开鬼门者，如开支河也，泄净府者，如开海口
也，故异治之而皆效也。方已备载前文，兹不再谈。愿人即此以悟其余之异治耳。
张公曰∶异治甚多，天师太略，予再广之。如人中暑也，或用热散，或用寒解；伤寒之法，或用
桂枝汤，或用麻黄汤是也。桂枝与麻黄，寒热各殊，如何用之而皆效？盖二物总皆散药，风寒初入于
营卫之间，热可散于初，寒可散于后。风寒初入于皮毛，将入胃经，则风邪尚寒，所以可用桂枝以
热散。风寒既由皮毛而入营卫，则寒且变热矣。盖正气逃入于府、而皮毛躯壳听邪外据，而成内热之
症，所以可用麻黄而寒散之也。治法虽有不同，祛邪则一，故用之而皆效耳。
中暑，或用香薷以热散之，或用青蒿以凉散之。似乎有异，不知非异也。盖中暑之症，感夏令之
热邪也。邪入脏腑，必须祛散。香薷与青蒿，同是祛暑热之圣物，性虽有寒热之分，而祛逐无彼此之异
也。此异治之宜知耳。其余异治之法，不可因此以更通之哉。
华君曰∶余亦不传。
论四物汤、逍遥散、六君子汤、归脾汤、小柴胡汤、参苏饮。
论补中益气汤、四君子汤等方剂的加减运用方法。
天师说：所谓“同治法”，是指使用同一个方剂来治疗多种不同的疾病。例如，四物汤可以治疗吐血，也可以治疗便血；逍遥散可以治疗肝气郁结（木郁），又可以治疗多种类型的郁证；六君子汤可以治疗饮食积滞损伤，又可以治疗痰湿与气机阻滞的积聚。然而，虽然方剂相同，但用药的轻重比例不同，加减变化各异，不能固执地认为一个方子只能治一种病，或者把治这种病的用法直接套用到另一种病上。比如，治疗吐血应在四物汤中加入麦冬、甘草；治疗便血则应在四物汤中加入地榆、黄芩之类。又如，治疗肝气郁结（木郁）应加入丹皮、栀子；治疗心火郁结（火郁）应加入黄连；治疗肺气郁结（金郁）应加入黄芩、苏叶；治疗脾气郁结（土郁）应加入石膏、知母；治疗肾气郁结（水郁）应加入泽泻、猪苓。如果是肉食积滞，应在六君子汤中加入山楂；米食积滞，应加入麦芽、枳壳；面食积滞，应加入萝卜子之类。同治法的奥妙，难道不值得仔细审察吗？
张公说：同治法不仅仅局限于上述三个方剂，我再加以扩充。归脾汤可以治疗因郁怒伤及肝脏的人，又可以治疗心气虚弱导致失眠的症状。小柴胡汤可以治疗伤风初起的病症，又可以调和伤寒误治后变生的坏病。参苏饮可以治疗风邪侵袭，又可以治疗气机郁滞导致的胸闷。补中益气汤可以提升阳气，又可以补益脾阴，并且在饮食刚受伤时帮助消化，在病邪变化后祛除邪气，疟疾依靠它来疏散邪气，泄泻依靠它来固护正气防止虚脱。四君子汤既可以补气不足，又可以清泻火有余，诸如此类，不胜枚举，这也全在于人善于领悟罢了。
华君说：我不传授这些。
天师说：所谓“异治法”，是指同一种疾病却采用不同的治疗方法。例如，人患中湿症，有的用“开鬼门”的方法，有的用“洁净府”的方法。虽然同样是水湿为患，为什么施用的治法不同却都有效呢？大概“开鬼门”，是开启人体毫毛腠理的毛孔；“洁净府”，是通利大小二便。治法虽然不同，但医理归于一致。这一致的道理是什么呢？大概水肿之症，原本是土气（脾胃之气）郁滞，土气郁滞则水液自然壅塞停滞而不流动。“开鬼门”，就像开挖支流河道；“洁净府”，就像疏通海口。所以虽然治疗方法不同，但都能见效。方剂已在前面文中详细记载，这里不再赘述。希望人们由此领悟其余的异治法。
张公说：异治法非常多，天师讲得太简略，我再加以扩充。例如人患中暑症，有的用热性药发散，有的用寒性药解表；治疗伤寒的方法，有的用桂枝汤，有的用麻黄汤。桂枝与麻黄，药性寒热各不相同，为什么使用都能见效？大概这两味药总属于发散药物。风寒刚刚侵入营卫之间，热邪可以在初期散发，寒邪可以在后期散发。如果风寒刚刚侵入皮毛，即将进入胃经，此时风邪尚带寒性，所以可以用桂枝以热性药发散。如果风寒已经由皮毛深入营卫，那么寒邪就会转化为热邪。大概正气退入脏腑，而皮毛躯壳听任邪气占据，从而形成内热之症，所以可以用麻黄以寒性药发散。治法虽然有不同，但祛除外邪的原则是一致的，所以使用都能见效。
对于中暑，有的用香薷以热性发散，有的用青蒿以凉性发散。看起来似乎不同，其实并非不同。大概中暑之症，是感受夏季的热邪。邪气侵入脏腑，必须祛除发散。香薷与青蒿，都是祛除暑热的圣药，药性虽有寒热之分，但祛除邪气的作用没有彼此的区别。这是异治法应当知道的道理。其余的异治法，不可因此就随意类推贯通。

On Siwu Tang (Four Substances Decoction), Xiaoyao San (Free and Easy Wanderer Powder), Liujunzi Tang (Six Gentlemen Decoction), Guipi Tang (Restore the Spleen Decoction), Xiao Chaihu Tang (Minor Bupleurum Decoction), and Shen Su Yin (Ginseng and Perilla Drink).
On the modification methods of Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction), Sijunzi Tang (Four Gentlemen Decoction), and other formulas.
The Heavenly Master said: The method of "Same Treatment" refers to using the same formula to treat multiple different diseases. For instance, Siwu Tang can treat hematemesis (vomiting blood) and also treat hematochezia (blood in stool); Xiaoyao San can treat Liver Qi Stagnation (Wood Depression) and also treat various types of depression; Liujunzi Tang can treat damage from dietary stagnation and also treat accumulation of phlegm and Qi obstruction. However, although the formula is the same, the dosage ratios differ, and the modifications vary. One cannot rigidly adhere to using one formula for only one disease, nor apply the usage for one disease directly to another. For example, when treating hematemesis, Ophiopogonis Radix (Maidong) and Glycyrrhizae Radix et Rhizoma (Gancao) should be added to Siwu Tang; when treating hematochezia, Sanguisorbae Radix (Diyu) and Scutellariae Radix (Huangqin) should be added. Furthermore, when treating Liver Qi Stagnation (Wood Depression), Moutan Cortex (Danpi) and Gardeniae Fructus (Zhizi) should be added; when treating Heart Fire Stagnation (Fire Depression), Coptidis Rhizoma (Huanglian) should be added; when treating Lung Qi Stagnation (Metal Depression), Scutellariae Radix (Huangqin) and Perillae Folium (Zisuye) should be added; when treating Spleen Qi Stagnation (Earth Depression), Gypsum Fibrosum (Shigao) and Anemarrhenae Rhizoma (Zhimu) should be added; when treating Kidney Qi Stagnation (Water Depression), Alismatis Rhizoma (Zexie) and Polyporus (Fuling) should be added. If there is meat food stagnation, Crataegi Fructus (Shanzha) should be added to Liujunzi Tang; if there is rice food stagnation, Hordei Fructus Germinatus (Maiya) and Aurantii Fructus (Zhike) should be added; if there is wheat food stagnation, Raphani Semen (Luobozhi) should be added. The subtleties of the Same Treatment method are certainly worthy of careful examination.
Master Zhang said: The method of Same Treatment is not limited to the three formulas mentioned above; I will expand upon it. Guipi Tang can treat individuals whose Liver is injured by depression and anger, and it can also treat symptoms of insomnia due to Heart Qi deficiency. Xiao Chaihu Tang can treat the initial stage of Wind-Cold invasion (common cold) and can also harmonize complicated conditions resulting from mishandled Cold Damage (Shanghan). Shen Su Yin can treat invasion by Wind pathogen and can also treat chest stuffiness caused by Qi stagnation. Bu Zhong Yi Qi Tang can raise Yang Qi and also tonify Spleen Yin; it aids digestion at the initial stage of injury and expels pathogens after transformation; malaria relies on it to disperse pathogens, and diarrhea relies on it to consolidate the body's resistance and prevent collapse. Sijunzi Tang can tonify insufficient Qi and also drain excessive Fire. There are many such examples, too numerous to enumerate, all depending on one's ability to comprehend deeply.

On Dampness Strike, Heat Stroke, and Cold Strike
The Heavenly Master said: The method of "Different Treatment" refers to employing different treatment methods for the same disease. For instance, a person suffering from Dampness Strike may be treated with the method of "Opening the Ghost Gate" or the method of "Purifying the Clean Mansion." Although both are water-dampness syndromes, why do different treatment methods yield effectiveness? Generally, "Opening the Ghost Gate" refers to opening the pores of the skin and hair; "Purifying the Clean Mansion" refers to promoting urination and defecation. Although the treatment methods differ, the underlying principle remains consistent. What is this consistency? The syndrome of edema originates from the stagnation of Earth Qi (Spleen/Stomach Qi). When Earth Qi stagnates, Water naturally becomes obstructed and fails to flow. "Opening the Ghost Gate" is like digging tributary channels; "Purifying the Clean Mansion" is like dredging the sea mouth. Therefore, although the treatments differ, both are effective. The formulas have been detailed in previous texts, so they are not discussed here. It is hoped that people will understand other Different Treatment methods through this insight.
Master Zhang said: There are many Different Treatment methods, and the Heavenly Master was too brief; I will expand upon them. For example, in cases of Heat Stroke, some use hot dispersing methods, while others use cold resolving methods; in treating Cold Damage, some use Guizhi Tang (Cinnamon Twig Decoction) and others use Mahuang Tang (Ephedra Decoction). Guizhi (Cinnamon Twig) and Mahuang (Ephedra) have distinct cold and hot properties, yet both are effective. This is because both are dispersing agents. When Wind-Cold initially invades between Ying (Nutritive) and Wei (Defensive) levels, heat can be dispersed early, and cold can be dispersed later. If Wind-Cold has just invaded the skin and hair and is about to enter the Stomach Meridian, the Wind pathogen is still cold, so Guizhi can be used to disperse with heat. If Wind-Cold has entered Ying and Wei from the skin and hair, the cold transforms into heat. Generally, when Healthy Qi retreats into the Fu organs, the skin and body shell are left to the pathogen's occupation, forming internal heat syndromes; thus, Mahuang can be used to disperse with cold. Although the treatment methods differ, the goal of expelling pathogens is the same, hence both are effective.
For Heat Stroke, some use Xiangru (Moslae Herba) to disperse with heat, while others use Qinghao (Artemisiae Annuae Herba) to disperse with coolness. They seem different, but they are not. Heat Stroke results from contracting Summer-Heat pathogens in summer. Once the pathogen enters the Zang-Fu organs, it must be expelled and dispersed. Both Xiangru and Qinghao are supreme herbs for dispelling Summer-Heat; although their properties differ in cold and hot nature, their efficacy in expelling pathogens is identical. This is what one should know about Different Treatment. Other Different Treatment methods cannot be arbitrarily generalized from this.
