治伤寒发汗不解。寒热往来。或中外诸邪热。口干烦渴。或下后热未愈。汗后劳复等证。
柴胡 人参 黄芩 甘草 大黄 当归 芍药（各半两）
上为末。每服钞三钱。水一盏。生姜三片。煎至七分。温服。日三。病热甚者。加减之。
琥按上方。即仲景大柴胡汤。去半夏枳实大枣。加人参当归也。以口干烦渴。故去半夏。复去大枣者。因烦渴一候。
必邪热甚而气上逆。恐大枣之甘。能壅气也。又以胃府但热而不实。故去枳实。或问热而不实。何以不去大黄。殊不知
方中用大黄者。止以除里热。又恐有伤阴。分之血。所以方中用芍药。复加当归也。愚又以方中惟人参一味。不宜与大
黄并用。有如中外邪热。或下后热未愈。则宜用大黄者。不宜加人参。恐人参甘温。反能助邪热也。又如汗后劳复。则
宜加人参者。不宜用大黄。以大黄苦寒。徒以致里虚也。且方后原云。病热甚者。加减之。夫热甚必实。寒甚必虚。若
热甚。还当加大黄。减人参也。后人不原制方之意。不知加减。一概并用。譬之陶氏黄龙汤。流祸至今而未已也。
疗伤寒少阳证。胸胁。痛往来寒热而呕。或咳而耳聋。脉尺寸俱弦。忌发汗。忌利小便。忌过大便。止宜和解。故

琥按上汤名三禁。而以利小便为一禁。其说盖自云。岐子保命集始。保命集云治少阳有三禁。不可汗。不可下。
不可利小便。此为三禁。独不观仲景辩少阳中风。首云。不可吐下。辩少阳伤寒。又云。不可发汗成无己明理论亦云。
少阳病邪在半表半里。既非发汗所宜。又非吐下所对。止宜和解。故云。三禁。若然。则是汗下之禁虽同。利小便与吐
大异先圣后贤其说。孰是孰非。愚曾细思之。而以仲景之言为是。若利小便。不在所禁也。据少阳篇坏病云。若已吐下。
发汗温针。谵语者。柴胡证罢。此为坏病。未闻云利小便而至坏也。又据柴胡汤后加减法云。若心下悸。小便不利者。
去黄芩。加茯苓。又内台方加药法云。如发热。小便不利者。和五苓散。益可见利小便。在所不禁矣。或云胆有上窍。
宜吐。木性曲直。风寒郁其经。则屈而不升。故宜用吐。以升发之。所以可吐篇云。大法。春宜吐。胆属少阳。而时应
乎春是。吐在所不禁。禁利小便者。以胆无下窍。且逆其性而导之也。其说近是。其理则非。断不可从。戒之慎之。
Treats conditions where the pathogenic factor of Shanghan (Cold Damage) has not been resolved after sweating therapy. Alternating chills and fever. Or various internal and external pathogenic heat. Dry mouth, vexation, and thirst. Or residual heat after purgative treatment. Recurrence due to overexertion after sweating, etc.
Chai Hu (Bupleuri Radix), Ren Shen (Ginseng Radix), Huang Qin (Scutellariae Radix), Gan Cao (Glycyrrhizae Radix et Rhizoma), Da Huang (Rhei Radix et Rhizoma), Dang Gui (Angelicae Sinensis Radix), Shao Yao (Paeoniae Radix Alba) (each half liang).
Grind the above herbs into powder. Take three qian per dose. Add one sheng of water and three slices of fresh ginger. Decoct until reduced to seven-tenths. Take warm. Three times daily. If the heat syndrome is severe, modify according to circumstances.
Hu notes: The above formula is essentially Zhang Zhongjing's Da Chai Hu Tang (Major Bupleurum Decoction), with Ban Xia (Pinelliae Rhizoma), Zhi Shi (Aurantii Fructus Immaturus), and Da Zao (Jujubae Fructus) removed, and Ren Shen (Ginseng Radix) and Dang Gui (Angelicae Sinensis Radix) added. Because of dry mouth and vexation/thirst, Ban Xia (Pinelliae Rhizoma) is removed. Da Zao (Jujubae Fructus) is further removed because the symptom of "vexation and thirst" indicates intense pathogenic heat and rebellious qi; it is feared that the sweet nature of Da Zao (Jujubae Fructus) may obstruct qi flow. Furthermore, since the stomach fu organ presents with heat but no excess accumulation (shi), Zhi Shi (Aurantii Fructus Immaturus) is removed. One might ask: if there is heat without excess, why is Da Huang (Rhei Radix et Rhizoma) not removed? It should be understood that Da Huang (Rhei Radix et Rhizoma) is used in this formula solely to clear interior heat. Additionally, to prevent injury to yin fluids and blood, Shao Yao (Paeoniae Radix Alba) is included, along with the addition of Dang Gui (Angelicae Sinensis Radix). I further argue that among the herbs in this formula, only Ren Shen (Ginseng Radix) should not be combined with Da Huang (Rhei Radix et Rhizoma). In cases of internal/external pathogenic heat or residual heat after purgation, Da Huang (Rhei Radix et Rhizoma) is appropriate, but Ren Shen (Ginseng Radix) should be avoided, as its sweet-warm nature might inadvertently assist the pathogenic heat. Conversely, in cases of recurrence due to overexertion after sweating, Ren Shen (Ginseng Radix) is appropriate, but Da Huang (Rhei Radix et Rhizoma) should be avoided, as its bitter-cold nature would merely cause interior deficiency. Moreover, the original text states: "If the heat syndrome is severe, modify." Severe heat implies excess; severe cold implies deficiency. If heat is severe, one should increase Da Huang (Rhei Radix et Rhizoma) and decrease Ren Shen (Ginseng Radix). Later practitioners, failing to understand the original intent of the formula formulation and lacking knowledge of modification, indiscriminately use all ingredients together. This is akin to Tao Hua's Huang Long Tang (Yellow Dragon Decoction), whose detrimental effects persist to this day.
Treats Shaoyang syndrome of Shanghan (Cold Damage). Pain in the chest and hypochondrium, alternating chills and fever with vomiting. Or coughing and deafness. Pulse is wiry at both cun and chi positions. Sweating therapy is contraindicated. Promoting urination is contraindicated. Profuse purgation is contraindicated. Only harmonizing (he jie) is suitable. Hence it is named San Jin Tang (Three Prohibitions Decoction).
This consists of the seven herbs from Zhang Zhongjing's Xiao Chai Hu Tang (Minor Bupleurum Decoction), with dosages halved. Its original modification methods are the same as above. Additional modification methods are recorded below.
In cases of alternating chills and fever with irregular menstruation, remove Ban Xia (Pinelliae Rhizoma), add Qin Jiao (Gentianae Macrophyllae Radix), Shao Yao (Paeoniae Radix Alba), Dang Gui (Angelicae Sinensis Radix), Zhi Mu (Anemarrhenae Rhizoma), Di Gu Pi (Lycii Cortex), Dan Pi (Moutan Cortex), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Bai Zhu (Atractylodis Macrocephalae Rhizoma), Fu Ling (Poria). For women suffering from deficiency-labor fever, add Ge Jie (Geckus), Chi Fu Ling (Poria cum Rubro). Combining Xiao Chai Hu Tang (Minor Bupleurum Decoction) and Si Wu Tang (Four Substances Decoction) in equal parts is named Tiao Jing Tang (Regulate Menstruation Decoction). (I believe that for women with Shanghan (Cold Damage) or wind-stroke, where menstruation has just started or stopped, presenting with alternating chills and fever like malaria, this decoction is suitable.) For non-pregnant individuals with vomiting, add Ban Xia (Pinelliae Rhizoma). For those without sweat, add Chai Hu (Bupleuri Radix). For those with aversion to cold, add Gui Zhi (Cinnamomi Ramulus). For those with spontaneous sweating, add Di Gu Pi (Lycii Cortex). For cough, add Zi Wan (Asterni Radix). To unblock meridians, add Jing San Leng (Curcumae Radix) and Guang Mao (Zedoary Rhizoma). For weakness, add Bie Jia (Testudinis Carapax et Plastrum). (Note: The aforementioned herb additions are methods for treating miscellaneous gynecological conditions.)
Hu notes: The above decoction is named San Jin Tang (Three Prohibitions Decoction), listing promoting urination as one prohibition. This theory likely originates from Yun Qizi's Bao Ming Ji (Collection for Preserving Life). Bao Ming Ji states that treating Shaoyang involves three prohibitions: no sweating, no purgation, no promoting urination. These are the three prohibitions. Have we not seen Zhang Zhongjing state regarding Shaoyang wind-strike that "vomiting and purgation are contraindicated," and regarding Shaoyang cold damage that "sweating is contraindicated"? Cheng Wuji in Ming Li Lun also states that Shaoyang pathogenic factors reside between exterior and interior; neither sweating nor vomiting/purgation is suitable, only harmonizing is appropriate. Thus, "three prohibitions" are mentioned. If so, while prohibitions against sweating and purgation align, promoting urination differs significantly from vomiting. Whose interpretation, that of the ancient sages or later worthies, is correct? I have pondered this carefully and side with Zhang Zhongjing. Promoting urination is not prohibited. According to the Shaoyang chapter on complicated diseases: "If vomiting, purgation, sweating, or warm needling have already been performed, resulting in delirium, the Chai Hu syndrome has ceased; this is called a complicated disease." There is no mention of promoting urination leading to complicated diseases. Furthermore, according to the modification rules after Chai Hu Tang: "If there is palpitation under the heart and difficulty urinating, remove Huang Qin (Scutellariae Radix) and add Fu Ling (Poria)." Also, according to Nei Tai Fang modifications: "If there is fever and difficulty urinating, combine with Wu Ling San (Five-Ingredient Powder with Poria)." This further confirms that promoting urination is not prohibited. Some argue that the Gallbladder has an upper orifice and vomiting is suitable. Wood naturally tends to curve and straighten; when wind-cold stagnates the meridian, it bends downward rather than ascending, so vomiting is suitable to promote ascent. Thus, Ke Tu Pian states: "The general principle is that spring favors vomiting." The Gallbladder belongs to Shaoyang, corresponding to spring, so vomiting is not prohibited. Promoting urination is prohibited because the Gallbladder lacks a lower orifice, and doing so goes against its nature. This argument seems plausible but is fundamentally incorrect. Do not follow it; beware and be cautious.
