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。

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。
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.
