证治两条（按：此处应当脱漏了“脉”字。） 方剂六首
老师说道：“疟疾的脉象自然呈现弦象。”（《外台秘要》在“老师说道”之上，有“辨疟脉”三个字。可以温补治疗。服用温药后，《脉经》记载为“若脉紧数者”。宋本《外台秘要》也作“数紧”。巢元方《诸病源候论》作“脉数而紧者”。《外台秘要》中还有“可吐之”，作“吐之瘥”。在“弦数”之上，有“脉”字。“消息止之”，作“消息之”。）
按此条，是通过脉象候诊来展示疟疾病证治疗的纲领。大概疟疾是半表半里的病证，它虽然有表里症状，也是少阳病邪气波及所致，不像伤寒太阳病、阳明病那样情机明显，所以它的汗法、吐法、下法，也与伤寒的治疗条例不同。所说的弦数脉多属热证，即白虎加桂枝汤、柴胡去半夏加栝蒌汤的证候。弦小紧脉，用下法可愈，即鳖甲煎丸。弦迟脉可以用温法，即柴胡桂枝干姜汤。弦紧脉可以发汗，即牡蛎汤。浮大脉可以吐法，即蜀漆散。治疗疟疾的方法，实在不能超出这几类了。程氏说不可考证，恐怕不是这样。另外《刺疟篇》说：“疟疾脉象小实急，灸治胫部少阴经穴位。”又按：弦数脉属于风热发作，通过饮食调理来停止它。《外台秘要》中没有“止”字，似乎意义稍长。《诸病源候论》收录本条，没有这两句，但有“凡疟疾发作前大约一顿饭的时间，才可以治疗，过了这个时间就错失良机”这十七个字，这原本是《刺疟篇》的文字。
又按：《外台秘要》引用的这一条后面有一条，说：“又辨析疟疾每年发作直到三年才发作，连日发作不解的，是因为胁下有痞块。治疗时不能攻伐痞块，只是耗伤津液。在发作前先发汗。服药后，先感到轻微寒冷，逐渐拉衣被覆盖以出汗，小便通利则痊愈。患疟疾的人，身体消瘦，皮肤上一定起鸡皮疙瘩。”（《诸病源候论》、《千金方》也有这条。《千金方》在“连日上”前有“或”字。《诸病源候论》文字略有差异，末尾截断处，作“夫疟其人形瘦皮必栗”。）
病疟在农历初一发作。（《外台秘要》在“病”上有“问”字。“其”，作“期”。《医心方·类聚》中，“圆”作“丸”，下文都相同。）
鳖甲煎丸方（《外台秘要》在“乌扇”下，无“烧”字。葶苈二分，石韦二分，无“去毛”字。浓朴三分下，有“炙”字。牡丹下，无“去心”字。半夏一分下，有“洗”字。蜣螂，熬，作“炙”。桃仁，作“三分去皮尖熬”。“灰”字，都作“土”字。一斛五斗，作“一斛五升”。按古方所说的“分”，是指裁分之分，不是六铢为一分的分。此方中的鳖甲，《千金方》注解说作三两，而锻灶下的灰，与清酒，都有定量，那么其他药物以“分”称量的，大概是后人妄自更改。其中的三分，宜作十八铢；六分，宜作一两十二铢；五分，宜作一两六铢；一分，宜作六铢；二分，宜作十二铢；四分，宜作一两，这才符合古义。又辑义指出，石韦，紫威，从草字头，是本书误笔写成手字旁。）
按弟子山内虑说：“此方中逐血的药特别多的原因，是因为疟疾久了则血道涩滞，与邪气搏结。杨仁斋有‘疟有水有血，当以常山、草果、槟榔、青皮、乌梅、甘草作剂，加五灵脂、桃仁为佐’的说法，他的意思可见一斑。这种说法是对的。此方，大概是崔氏所说的羁縻攻伐之法。（见《外台秘要》瘕疰门中。）注家认为是急治，恐怕错误。另外《本草》鼠妇条，《图经》说：张仲景主治久疟大鳖甲丸中使用它，因为它主治寒热。另外芒硝条，陶隐居引用皇甫士安解散硝石大凡说云：硝石，三月采于赤山。”
圣济总录鳖肉煎丸。（主证同）不用鳖甲，用生鳖肉半斤，按食用方法处理。去掉紫威、蜂窠、赤硝，加海藻、紫菀、大戟，各一分。（其余药也都是一分。）桑螵蛸一两，修制与本方相同。
老师说道：“阴气孤绝。”（《外台秘要》引文，在“老师说道”之上，有“辨疟病”三个字。则热而，作“而脉微者其候必七字”。肌，作“脱”。《医心方·类聚》，也作“脱”。）
温疟，其脉象如同平人（《脉经》作“疟但见热者，温疟也。其脉平。身无寒但热，骨节疼烦，时呕。朝发暮解，暮发朝解，名曰温疟。白虎加桂枝汤主之。《诸病源候论》说：患病疟疾六七天，只见到热的，就是温疟了。另外《千金方》、《外台秘要》，文字互有差异，现在不繁琐记载。”）
按《内经》认为先热后寒为温疟，张仲景则认为无寒但热为温疟，稍微与上一条瘅疟相近。大概是另外阐发一个义理，不宜援引《内经》的温疟来说明。《内经》称冬天受寒，春天必定发生温病，而张仲景则说：“太阳病，发热而渴，不恶寒的，称为温病。”知道温疟的“温”，与温病的“温”，实际含义相同。（详细论述在《伤寒论述义》中。）疟邪本来在少阳，所以时常呕吐。此证则是热邪熏蒸胃腑更为严重，所以身无寒但热。再看骨节疼烦，则仍有表邪存在，所以在白虎汤中加入桂枝，以兼治表里。此证，白虎汤清凉，而少阳之邪也得以解除，犹如三阳合病用白虎汤的例子。但其脉象如平人，各家注解未透彻，我也未曾遇到此病，无法知晓其中道理，暂且存疑。
疟疾多寒的，名叫牡疟。（宋本、《外台秘要》，作“牡疟”，下方的蜀漆散相同。大概其作“牝”的，是程衍道主观修改的，存留考察。）
蜀漆散方（《外台秘要》引文，作“蜀漆，洗去腥。云母，龙骨。上三味等分，捣筛为散。在发作前一顿饭的时间，用清酢浆水和服半钱。临发作时，再服一钱。温疟者，加蜀漆半分。云母，炭火烧三日三夜使用。按《外台秘要》，似乎是正确的。《千金方》，在一炊下，有“顷”字。）
按：云母、龙骨的性能作用，注家所说，似乎不明确。考据《本草》，也未见有治疗疟疾的功效。我私下认为这两味及牡蛎，都有化解水结的功效，所以与蜀漆相配，能豁除疟痰。《肘后备急方》说：“老疟久不断绝。未龙骨方寸七，发作前一时辰，用酒一升半煮三沸，趁热全部服下。温覆取汗，便立即见效。《千金翼方》说：治疗痰饮头痛，往来寒热方。常山一两，云母粉二两。上二味为散，熟汤送服方寸匕。吐出来就停止。如果吐不尽再服。并与此方，其意相似。另外《刺疟篇》次注说：在发作之前，真气与邪气分居，波浪隆起不起，所以可治。过时则真邪相合，攻之则反伤真气，所以说错失时机。得到这个说法，而这个方的服法，意义更加明确了。（辑义所引，得效方文，本出《三因方》。丹溪纂要文，本出《保命集》。）
附《外台秘要》方
牡蛎汤（《外台秘要》：甘草炙。上四味切。以水先洗蜀漆三遍，去腥。用水八升，煮蜀漆及麻黄，去沫，取六升，纳入二物，再煎取二升，去滓，温服一升。即吐勿更服则愈。）
按此方，吐而兼汗，是张戴人的方法，间或有此类。但我曾用它治疗夜间发作的疟疾，以及热甚无汗者，服药后不吐而汗出，稍稍邪气解除就痊愈了。尤氏认为外攻之力较猛，确实如此。
柴胡去半夏加栝蒌汤（《外台秘要》：甘草下，有“炙”字。生姜三两，大枣下，有“擘”字。七味下，有“切”字。再，作“更”。日二服，作“日三”。《千金方》，名柴胡栝蒌汤，用柴胡三两，大枣二十枚，讹误。）
柴胡桂枝干姜汤（原注：如热，是“如神”之讹。）
按此方，宋人取而附于此，大概有所依据。现在根据治疗疟疾“如神”的说法，大概不虚妄。《伤寒论》太阳下编所用，系于太少并病，而兼有饮结者。如此条，徐注为确切。（本于赵氏。）然而疟疾有痰积聚，许仁则既有其说，那么此方所用，也是兼治饮结者。大概其趣味看似不同而实质相同。
Two Symptom Patterns (Note: The character "pulse" [Mai] is likely missing here.) Six Formulas
The Master said, "The pulse of malaria naturally presents as wiry [Xian]." (*Wai Tai Mi Yao* adds the phrase "Differentiating Malaria Pulses" before "The Master said." It suggests warm treatment. After administering warm medicines, *Mai Jing* records it as "If the pulse is tight and rapid." Song edition of *Wai Tai Mi Yao* also reads "rapid and tight." Chao Yuan-fang's *Zhu Bing Yuan Hou Lun* reads "the pulse is rapid and tight." *Wai Tai Mi Yao* also mentions "can induce vomiting," reading "vomiting leads to recovery." Before "wiry and rapid," the character "pulse" is present. "Adjust and stop" reads "adjust it." Note that in *Wai Tai Mi Yao*, there is no character for "stop," which seems to extend the meaning slightly. *Zhu Bing Yuan Hou Lun* includes this passage but omits these two sentences; instead, it contains seventeen characters stating: "For all malaria, treatment can be administered approximately one meal's time before onset; if missed, the opportunity is lost." These seventeen characters originally belong to the "Acupuncture for Malaria" chapter.)
According to this passage, pulse diagnosis serves as the guiding principle for treating malaria symptoms. Generally, malaria is a disease located at the half-exterior and half-interior level. Although it may present with exterior or interior signs, these are also extensions of Shaoyang pathogenic factors, differing significantly from the mechanisms of Taiyang and Yangming diseases in Cold Damage syndrome. Therefore, its methods of sweating, vomiting, and purging differ from those used in Cold Damage treatments. A wiry and rapid pulse indicates excessive heat, corresponding to the patterns treated by Baihu Jia Guizhi Tang (White Tiger plus Cinnamon Twig Decoction) and Chaihu Qu Banxia Gua Lou Tang (Bupleurum Decoction without Pinellia, plus Trichosanthes Root). A wiry, small, and tight pulse indicates that purgation will lead to recovery, corresponding to Biejia Jian Wan (Clam Shell Building-Dispersing Pill). A wiry and slow pulse indicates that warming therapy is appropriate, corresponding to Chaihu Guizhi Ganjiang Tang (Bupleurum, Cinnamon Twig, and Dried Ginger Decoction). A wiry and tight pulse indicates that diaphoresis (sweating) is indicated, corresponding to Musi Tang (Oyster Shell Decoction). A floating and large pulse indicates that emesis is indicated, corresponding to Shuqi San (Freesia Powder). The methods for treating malaria essentially cannot exceed these categories. Mr. Cheng claimed these were untraceable, which is likely incorrect. Furthermore, the "Acupuncture for Malaria" chapter states: "When the malaria pulse is small, solid, and urgent, moxa should be applied to the Shaoyin points on the lower legs." Additionally, a wiry and rapid pulse signifies wind-heat onset; it can be managed through dietary adjustments. *Wai Tai Mi Yao* lacks the character for "stop" in this context, suggesting a slightly different interpretation. *Zhu Bing Yuan Hou Lun* records this section without these two sentences but includes seventeen characters from the "Acupuncture for Malaria" chapter regarding timing.
Furthermore, following the citation in *Wai Tai Mi Yao*, there is another passage: "Regarding malaria that recurs annually up to every three years, or continuous daily attacks that do not resolve, this is due to a mass under the hypochondrium. Treatment should not attack the mass directly, as this only depletes body fluids. Instead, induce sweating prior to the onset. After taking the decoction, if the patient feels slight chills, gradually cover with clothing to induce sweating; when urination becomes smooth, the patient recovers. Patients with malaria appear emaciated, and their skin must exhibit gooseflesh." (*Zhu Bing Yuan Hou Lun* and *Qianjin Fang* contain this passage. In *Qianjin Fang*, the character "or" appears before "continuous days." *Zhu Bing Yuan Hou Lun* has slight textual variations, ending with "As for malaria, the person is emaciated and the skin must shiver.")
Malaria occurring on the first day of the lunar month. (*Wai Tai Mi Yao* adds the character "ask" before "disease." The character "qi" [his/her/its] is read as "qi" [period]. In *Yi Xin Fang / Lei Ju Yi Shu*, "yuan" [round] is read as "wan" [pill], consistent throughout the text below.*)
**Biejia Jian Wan Formula** (*Wai Tai Mi Yao*: No character for "burn" after "Wushan." Tingli [Descurainia Seed] 2 fen, Shiwei [Pyrosia Leaf] 2 fen, omitting "remove hairs." Houpo [Magnolia Bark] 3 fen, adding "roasted" after. Mudan [Moutan Cortex], omitting "remove heart." Banxia [Pinellia Tuber] 1 fen, adding "wash." Qianglang [Dung Beetle], "stir-fry" instead of "bake." Taoren [Peach Kernel], specified as "3 fen, remove skin and tip, stir-fry." The character "hui" [ash] is written as "tu" [soil] throughout. "One hu five dou" is recorded as "one hu five sheng." Note: In ancient prescriptions, "fen" refers to proportional division, not the weight unit where six zhu equals one fen. In this formula, Biejia [Trionyx Carapace] is noted in *Qianjin Fang* as 3 liang. Since the ash from the forge and Qingjiu [clear wine] have fixed quantities, the other herbs measured in "fen" were likely altered by later editors. Thus, 3 fen should be 18 zhu; 6 fen should be 1 liang 2 zhu; 5 fen should be 1 liang 6 zhu; 1 fen should be 6 zhu; 2 fen should be 12 zhu; 4 fen should be 1 liang. This aligns with ancient principles. Also, editorial notes indicate Shiwei was mistakenly written with a hand radical instead of grass radical.)
Disciple Shannai Lu stated: "This formula contains many blood-dispelling herbs because prolonged malaria causes blood stasis and binding with pathogens. Yang Renzhai proposed that since malaria involves water and blood, one should use Changshan [Radix Dichroae], Caoguo [Tsaoko Fructus], Binglang [Areca Seed], Qingpi [Aurantii Fructus Pericarpium], Wumei [Mume Fructus], and Gancao [Licorice Root] as the base, supplemented by Wulingzhi [Trogopterus Dung] and Taoren [Peach Kernel]. This insight is valid. This formula represents what Cui Shi described as 'indirect attacking' (see *Wai Tai Mi Yao*, Zhong Man Section). Commentators consider it an urgent treatment, which is likely mistaken. Additionally, regarding Shufu [Isotoma Fruit] in Ben Cao, Tu Jing states: Zhang Zhongjing used it in the Large Biejia Wan for chronic malaria because it treats chills and fever. Regarding Mangxiao [Natrii Sulfas], Tao Hongjing quotes Huangfu Mi'an saying: Natrii Sulfas is harvested in March from Red Mountain."
**Shengji Zonglu Bie Rou Jian Wan** (Indications same). Does not use Biejia; uses 0.5 jin of raw Bie Rou [Trionyx Flesh], prepared for consumption. Removes Ziwei [Stemona Radix], Fengke [Honeycomb], Chixiao [Red Natrii Sulfas]; adds Haizao [Sargassum Thallus], Ziwan [Asteris Radix], Daji [Euphorbiae Pekinensis Radix], each 1 fen. (Other herbs are also 1 fen each.) Sangpiaoxiao [Mantis Egg Case] 1 liang. Preparation is the same as the main formula.
The Master said: "Yin qi is isolated and exhausted." (*Wai Tai Mi Yao* adds "Differentiating Malaria Disease" before "The Master said." "Ze re er" is read as "Er mai wei zhe qi hou bi" [If the pulse is faint, the prognosis is certain]. "Ji" [muscle] is read as "tuo" [exhausted]. *Lei Ju Yi Shu* also reads "tuo".)*
**Wen Re** (Warm Malaria): Its pulse resembles that of a healthy person. (*Mai Jing* reads: "When malaria presents only with heat, it is Warm Malaria. The pulse is normal. The body has no chills, only heat; joints are painful and vexed; occasional vomiting. Onset in morning resolves evening; onset in evening resolves morning. Named Warm Malaria. Treated with Baihu Jia Guizhi Tang. *Zhu Bing Yuan Hou Lun* says: If malaria persists for six or seven days and presents only with heat, it is Warm Malaria." *Qianjin Fang* and *Wai Tai Mi Yao* have variant texts, not listed here for brevity.*)
According to *Nei Jing*, malaria starting with heat followed by cold is called Wen Re. Zhang Zhongjing defines it as having no chills, only heat, which is slightly similar to the previous pattern of Dan Re (Cachectic Malaria). It seems to introduce a separate conceptual meaning, so one should not cite *Nei Jing*'s definition of Wen Re here. *Nei Jing* states that winter injury by cold leads to warm diseases in spring, whereas Zhang Zhongjing states: "Taiyang disease with fever, thirst, and aversion to cold absent is termed Warm Disease." Thus, the "warmth" in Wen Re and Warm Disease shares the same underlying meaning (detailed in *Shanghan Lun Shuyi*). The malaria pathogen resides in Shaoyang, causing occasional vomiting. In this condition, heat pathogen steaming the stomach is severe, hence no chills, only heat. Considering joint pain and vexation, there remains an exterior pathogen. Therefore, Guizhi [Cinnamomi Ramulus] is added to Baihu Tang (White Tiger Decoction) to treat both exterior and interior. Here, Baihu Tang clears heat, resolving Shaoyang pathogen, similar to using Baihu Tang for combined Three-Yang disease. However, the pulse being "like normal" is not clearly explained by commentators. Having never encountered this specific presentation, I leave it as a doubt.
Malaria with predominant chills is named Mu Re (Male Malaria). (Song edition and *Wai Tai Mi Yao* read "Mu Re"; the subsequent Shuqi San is identical. The variant "Pin Re" [Female Malaria] was likely a subjective alteration by Cheng Yandao; kept for reference.)
**Shuqi San Formula** (*Wai Tai Mi Yao* citation: "Shuqi, wash to remove fishy odor. Yunmu [Muscovite], Longgu [Fossilized Bones]. These three ingredients in equal parts, grind into powder. Take half a qian mixed with clear vinegar juice one meal's time before onset. At onset, take another qian. For Warm Malaria, add half a qian of Shuqi. Yunmu, fired in charcoal fire for three days and nights." *Wai Tai Mi Yao* seems correct. *Qianjin Fang* adds "moment" after "one meal's time".)
Commentary: The properties of Yunmu and Longgu are unclear in commentaries. Examination of Ben Cao reveals no specific efficacy for malaria. I suspect these two herbs, along with Musi [Oyster Shell], possess the ability to resolve fluid accumulations. Combined with Shuqi, they can expel malaria phlegm. *Zhouhou Beiji Fang* states: "For chronic, persistent malaria. One cun square of Longgu, one hour before onset, boil in 1.5 sheng of wine for three boils. Drink hot while covered to induce sweat; effective immediately. *Qianjin Yi Fang* states: For phlegm-fluid headache with alternating chills and fever. Changshan [Radix Dichroae] 1 liang, Yunmu Fen [Powder] 2 liang. Grind into powder, take with cooked water using a fang cun spoon. Induce vomiting to stop symptoms. If vomiting is incomplete, administer again. This intent is similar to the current formula. Furthermore, the commentary on the 'Acupuncture for Malaria' chapter states: Treat before onset when true qi and pathogen are separated and waves have not risen. If delayed, true qi and pathogen merge, and attacking harms true qi, hence 'missing the time.' Understanding this clarifies the administration method of this formula." (Editorial notes cite *De Xiao Fang* from *San Yin Fang*; Danxi Cuanya from *Bao Ming Ji*.)
**Appendix: *Wai Tai Mi Yao* Formula**
**Musi Tang** (*Wai Tai Mi Yao*: Gancao [Licorice Root] roasted. Cut the four ingredients. Wash Shuqi three times with water to remove fishy odor. Add 8 sheng of water, boil Shuqi and Mahuang [Ephedrae Herba], skim foam, reduce to 6 sheng. Add remaining two herbs, boil down to 2 sheng. Strain, warm, drink 1 sheng. If vomiting occurs, do not take more; recovery follows.)
Commentary: This formula induces both vomiting and sweating, a method attributed to Zhang Dairen. I have used it for nocturnal malaria and cases with high fever and no sweat. Post-administration, patients sweated rather than vomited, leading to gradual resolution. You Shi correctly noted its strong exterior-attacking power.
**Chaihu Qu Banxia Gua Lou Tang** (*Wai Tai Mi Yao*: Gancao [Licorice Root] roasted. Shengjiang [Fresh Ginger] 3 liang. Dazao [Jujubae Fructus] cracked. Seven ingredients cut. "Re-" read as "Geng" [more]. Twice daily read as "Three times daily." *Qianjin Fang* names it Chaihu Gua Lou Tang, using Chaihu [Bupleuri Radix] 3 liang, Dazao 20 pieces; considered erroneous.)
**Chaihu Guizhi Ganjiang Tang** (Original note: "Ru Re" [Like Heat] is a typo for "Ru Shen" [Like God/Miraculous].)
Commentary: Song dynasty editors attached this formula here, likely based on evidence. Current application for malaria aligns with the "miraculous" description. In the Taiyang section of *Shanghan Lun*, it is used for concurrent Taiyang-Shaoyang disease with fluid retention. As per this passage, Xu's annotation is accurate (based on Zhao's work). However, since malaria involves phlegm accumulation, as noted by Xu Renze, this formula also addresses fluid retention. Though the applications seem different, the essence is the same.
