师曰。疟脉自弦。弦数者多热。弦迟者多寒。弦小紧者下之瘥。弦迟者可温之。弦紧者可发汗针
灸也。浮大者可吐之。弦数者风发也。以饮食消息止之。
疟者少阳之邪。弦者少阳之脉。有是邪。则有是脉也。然疟之舍。固在半表半里之间。而疟之气。
则有偏多偏少之异。故其病有热多者。有寒多者。有里多而可下者。有表多而可汗、可吐者。有风从
热出。而不可以药散者。当各随其脉而施治也。徐氏曰。脉大者为阳。小者为阴。紧虽寒脉。小紧则
内入而为阴矣。阴不可从表散。故曰下之愈。迟既为寒。温之无疑。弦紧不沉。为寒脉而非阴脉。非
阴故可发汗针灸也。疟脉概弦。而忽浮大。知邪在高分。高者引而越之。故可吐。喻氏曰。仲景既云
弦数者多热矣。而复申一义云。弦数者风发。见多热不已。必至于极热。热极则生风。风生则肝木侮
土而传其热于胃。坐耗津液。此非可徒求之药。须以饮食消息。止其炽热。即梨汁、蔗浆。生津止渴
之属。正内经风淫于内。治以甘寒之旨也。

老师说：疟疾的脉象自然呈现弦脉。弦而数的脉象，多表现为热证；弦而迟的脉象，多表现为寒证。弦而小紧的脉象，可以用下法治疗而痊愈；弦而迟的脉象，可以用温法治疗；弦而紧的脉象，可以用发汗或针灸治疗；浮大而有力的脉象，可以用吐法治疗。弦而数的脉象属于风热发作，可以通过饮食调理来制止它。
疟疾是少阳经（主枢机，位于半表半里）受邪所致，弦脉是少阳经的典型脉象。有这种邪气，就会出现这种脉象。然而，疟疾的病位固然在半表半里之间，但疟疾的气机变化，则有偏盛偏衰的不同。所以疾病表现有热多者，有寒多者，有病位在里且可用下法者，有病位在表且可用汗法、吐法者，有风从热出而不宜用药物发散者。应当根据各自的脉象来实施治疗。徐氏说：脉大属于阳，脉小属于阴。紧脉虽然是寒脉，但小紧则说明邪气内入而属阴了。阴证不可从体表发散，所以说用下法可愈。迟脉既为寒象，用温法治疗毫无疑问。弦紧脉不沉，属于寒脉而非阴脉。既然不是阴证，所以可以用发汗或针灸治疗。疟疾的脉象概略都是弦脉，如果突然见到浮大脉，就知道邪气在高位（上焦）。位置高的邪气，引导其向上越出，所以可以用吐法。喻氏说：张仲景既然说了弦数脉多热，又补充阐述一点：弦数脉属于风热发作，说明热势不止，必然发展到极热。热极则生风，风生则肝木克制脾土，并将热邪传于胃中，坐视津液耗损。这不能单纯依靠药物解决，必须通过饮食调理，遏制炽热的火势。像梨汁、甘蔗浆这类生津止渴的食物，正符合《内经》中“风淫于内，治以甘寒”的宗旨。
患疟疾如果在农历初一发病，应当在十五天后痊愈；假如没有好，应当在当月月底解除。如果到了月底还没有好，该怎么办呢？老师说：这是因为邪气结聚形成了瘕块（腹内结块），名叫疟母（疟疾日久形成的胁下肿块）。应当紧急治疗，适宜使用鳖甲煎丸。
天气每十五日更替一次，人体的正气也每十五日更替一次。正气更替时，邪气应当解除。否则三十天时，天地人的正气再次更替，邪气自然无法留存。假如再次更替后仍未痊愈，邪气必定依附于血液，凭借痰饮，结聚成瘕块，僻处于胁下，将形成顽固难除的态势。所以应当紧急治疗。鳖甲煎丸中含有许多行气逐血的药物，但不嫌其药性峻猛。一天服用三次，不嫌其治疗急切。这就是所谓趁邪气尚未集结完备时攻击它。
鳖甲煎丸方剂组成：
鳖甲（十二分，炙） 乌扇（三分，烧制，即射干） 黄芩（三分） 柴胡（六分） 鼠妇（三分，熬制）
干姜 大黄 桂枝 石韦（去毛） 厚朴 紫葳（即凌霄花） 阿胶（各三分） 芍药 牡丹皮（去心）
䗪虫（各五分） 半夏（一分） 葶苈子 人参（各一分） 瞿麦（二分） 蜂房（四分，炙） 赤硝
（十二分） 蜣螂（六分，熬制） 桃仁（二分，去皮尖，研碎）
以上二十三味药，研成细末。取灶下灰一斗，清酒一斛五升，浸泡灶下灰，等到酒消耗掉一半时，将鳖甲放入其中，煮至烂熟，加入胶漆，绞取汁液，纳入诸药，煎制成丸，如梧桐子大小。空腹服用七丸，每日三次。《千金方》中使用鳖甲十二片，另有海藻三分，大戟一分，没有鼠妇、赤硝两味药。
老师说：阴气孤立绝灭，阳气独自发动，则出现发热、气短、心中烦闷冤屈感，手足发热且想呕吐，名叫瘅疟（dàn nuè，一种但热不寒的疟疾）。如果只有发热而没有恶寒，邪气内藏于心，外舍于分肉（肌肉间隙）之间，使人肌肉消烁消瘦。
这段文字与《内经》论述瘅疟的文章大体相同。阴气虚弱的人，阳气必然发动。发动则足以伤气耗神，所以会出现气短和心中烦闷。四肢是诸阳之本，阳气旺盛则手足发热。想呕吐，是因为热邪干扰胃腑。邪气内藏于心，瘅疟属于阳邪，心属于阳脏，以阳邪从阳脏，所以邪气外舍于分肉，而其气机则内通心脏。肌肉消烁，是因为肌肉属阴，阳极则阴消。
温疟的症状，脉象如同平时（无明显异常变化），身体没有恶寒只有发热，骨节烦痛，时而呕吐，用白虎加桂枝汤主治。
这段文字与《内经》论述温疟的文章不同。《内经》讲的是病因，这里详细讲述脉象与症状。瘅疟和温疟，都是只有发热没有恶寒，都有呕吐，但病因不同。瘅疟是肺中素有热邪，加上外感风寒，属于表寒里热的证候。因为阴气内部虚弱，不能与阳气相争，所以不产生恶寒。温疟是邪气内藏于肾中，到春夏季节才发作，属于伏气外出的证候。寒气蓄积久了转化为热，所以也不产生恶寒。脉象如平时一样，是因为病非突然感受，所以脉象像他平时的脉象。骨节烦痛、时而呕吐，是因为热邪从肾发出，外舍于其合穴部位，并向上合并于阳明经。白虎汤甘寒以清除热邪，桂枝则是顺应病势将其透达出去。
白虎加桂枝汤方剂组成：
知母（六两） 石膏（一斤） 甘草（二两，炙） 粳米（二合） 桂枝（三两）
以上五味药，用水一斗，煮至米熟汤成，去渣滓。温服一升，每日三次。
疟疾恶寒多，并非真正的寒证，而是阳气被痰饮所遏制，不能外出到达肌表，而只内伏于心间。心是牡脏（阳脏），所以名叫牡疟。蜀漆能涌吐疟疾之痰，痰去则阳气伸展，寒症自愈。选用云母、龙骨，是因为蜀漆上越之力猛烈，担心它会同时扰动心中的神与气。
蜀漆散方剂组成：
蜀漆（洗去腥味） 云母（烧制两日夜） 龙骨（等分）
以上三味药，捣碎研成散剂。在疟疾发作前，用浆水送服半钱匕。
附《外台秘要》三方
以上四味药，用水八升，先煮蜀漆、麻黄，去掉上面的泡沫，得到六升药液，纳入其他药物，煮取二升。温服一升。如果服药后呕吐，则不要继续服用。
按语：这是宋代孙奇等人所附。大概也是蜀漆散的意思，但向外攻伐的力量较为猛烈。赵氏说：牡蛎能软坚散结，麻黄不仅发散寒邪，而且可以发越阳气，使之气通达于外。结散阳通，病自然痊愈。
柴胡去半夏加栝蒌根汤 治疗疟疾发病口渴者，也治疗劳疟（久疟体虚者）。
柴胡（八两） 人参 黄芩 甘草（各三两） 栝蒌根（四两） 生姜（二两） 大枣（十二枚）
以上七味药，用水一斗二升，煮取六升，去渣滓，再煎，取三升。温服一升，每日两次。
柴胡桂姜汤 治疗疟疾，恶寒多微有发热，或者只有恶寒没有发热。服用一剂效果神奇。
柴胡（半斤） 桂枝（三两） 干姜（二两） 栝蒌根（四两） 黄芩（三两） 甘草（二两，炙）
牡蛎（二两，熬制）
以上七味药，用水一斗，煮取六升，去渣滓，再煎，取三升。温服一升，每日三次。初服时感觉轻微心烦，再服后出汗便痊愈。
赵氏说：此方与牡疟相似但实际上不同。牡疟是邪气客居心下，此方针对的是风寒湿痹阻于肌表。肌表既已痹阻，阳气不能通达于外，于是郁伏在营血之中。阳气化热，血液停滞形成瘀血，附着在该处。当卫气运行二十五度经过此处时，病症就发作。侵入营分的邪气，既没有外出的趋势，而素来痹阻的营气，也不出来与阳气相争，所以发热少或无发热。因此用柴胡作为君药，发散郁伏的阳气；黄芩作为佐药，清解半里的热邪；桂枝、干姜，用来通散肌表的痹阻；栝蒌根、牡蛎，用来消除残留的热邪，消散瘀血；甘草调和诸药，调理阴阳。得汗则痹邪解散，血热运行，病就痊愈了。
The Master said: The pulse of malaria (Nüe Bing) is naturally wiry (Xian). A wiry and rapid (Shu) pulse indicates predominantly heat; a wiry and slow (Chi) pulse indicates predominantly cold. A wiry, small, and tight pulse may be treated with purgation to achieve recovery. A wiry and slow pulse may be treated with warming methods. A wiry and tight pulse may be treated with diaphoresis or acupuncture and moxibustion. A floating and large pulse may be treated with emesis. A wiry and rapid pulse indicates wind-heat onset; this can be controlled through dietary management.
Malaria is an evil affecting the Shaoyang (Lesser Yang) channel, which governs the pivot and resides between the exterior and interior. The wiry pulse is the characteristic pulse of the Shaoyang channel. Where there is such an evil, there appears such a pulse. However, while the seat of malaria is indeed between the exterior and interior, the qi dynamics of malaria vary in their excess or deficiency. Thus, the disease manifests as having more heat, more cold, pathology primarily in the interior amenable to purgation, pathology primarily in the exterior amenable to diaphoresis or emesis, or wind emerging from heat which should not be dispersed by medication alone. Treatment must be administered according to the respective pulses.
Xu stated: A large pulse belongs to Yang; a small pulse belongs to Yin. Although a tight pulse is a cold pulse, a small and tight pulse indicates that the pathogen has entered inward and become Yin. Yin patterns cannot be dispersed from the exterior; therefore, it is said that purgation leads to healing. Since a slow pulse indicates cold, warming treatment is undoubtedly appropriate. A wiry and tight pulse that is not deep is a cold pulse but not a Yin pulse. Since it is not a Yin pattern, diaphoresis or acupuncture and moxibustion are permissible. Generally, the malaria pulse is wiry; if it suddenly becomes floating and large, it indicates the pathogen is in the high position (upper Jiao). For pathogens in high positions, guiding them upward and outward via emesis is indicated.
Yu stated: Zhang Zhongjing mentioned that a wiry and rapid pulse indicates much heat, and further elaborated: a wiry and rapid pulse signifies wind-heat onset. This implies that if heat persists, it will reach extreme heat. Extreme heat generates wind; wind generation causes Liver Wood to overact on Spleen Earth, transmitting heat to the Stomach, thereby consuming body fluids. This cannot be addressed solely by medication; one must use dietary management to curb the blazing heat. Substances like pear juice and sugarcane syrup, which generate fluids and quench thirst, align with the principle in the *Neijing* ("Wind rampant within, treat with sweet and cold").
If malaria begins on the first day of the lunar month, it should resolve after fifteen days. If it does not improve, it should resolve by the end of the month. If it does not resolve then, what should be done? The Master said: This occurs when the evil condenses into a mass (Jia), named Malaria Mother (Nu Mu - a spleenomegaly associated with chronic malaria). It requires urgent treatment, preferably using Biejia Jian Wan (Turtle Shell Decoction for Reducing Masses).
Heavenly Qi changes every fifteen days, and human Qi also changes every fifteen days. When Qi changes, the evil should resolve. Otherwise, at thirty days, the Qi of heaven and humanity changes again, and the evil cannot remain. If it still does not heal after this change, the evil must have attached itself to blood and relied on phlegm-fluids to form a mass, lodging in the hypochondrium. It will assume a posture of stubborn resistance. Therefore, urgent treatment is required. Biejia Jian Wan contains many herbs for moving Qi and driving out blood stasis, yet its harshness is not a concern. Taken three times a day, its urgency is not a concern. This is known as attacking the enemy before it has fully assembled.
**Biejia Jian Wan Formula:**
Bie Jia (Turtle Shell, 12 fen, processed with fire)
Wu Shan (Ophiopogon/Tuberous Ophiopogon Rhizome, 3 fen, roasted; i.e., She Gan/Iris Tectori Rhizoma)
Huang Qin (Scutellaria Root, 3 fen)
Chai Hu (Bupleurum Root, 6 fen)
Shu Fu (Male Fly, 3 fen, processed)
Gan Jiang (Dried Ginger)
Da Huang (Rhubarb Root)
Gui Zhi (Cinnamon Twig)
Shi Wei (Pyrrosia Leaf, de-haired)
Hou Po (Magnolia Bark)
Zi Wei (Lagerstroemia Flower, i.e., Ling Xiao Hua/Crape Myrtle Bark/Flower)
E Jiao (Donkey-hide Gelatin, 3 fen each with above)
Shao Yao (Peony Root)
Mu Dan Pi (Moutan Cortex, heart removed)
Jue Chong (Ground Beetle, 5 fen each with above)
Ban Xia (Pinellia Tuber, 1 fen)
Ting Li Zi (Descurainia Seed)
Ren Shen (Ginseng Root, 1 fen each with above)
Qu Mai (Polygonum Aviculare Herb, 2 fen)
Feng Ke (Honeycomb, 4 fen, processed)
Chi Xiao Dou (Red Adzuki Bean/Chixiaodou, 12 fen)
Qiang Lang (Dung Beetle, 6 fen, processed)
Tao Ren (Peach Kernel, 2 fen, skin and tip removed, crushed)
These twenty-three ingredients are powdered. Take one dou of ash from the kitchen stove and five sheng of clear wine. Soak the ash in the wine. When half the wine has been absorbed, place the Bie Jia in the mixture and boil until soft and rotten. Add gelatin and lacquer, strain to obtain the juice, add the other medicines, and decoct into pills the size of wutong seeds. Take seven pills on an empty stomach, three times daily. The *Qianjin Fang* uses twelve slices of Bie Jia, plus San Zao (Sargassum Thallus, 3 fen) and Da Ji (Euphorbia Root, 1 fen), omitting Shu Fu and Chi Xiao Dou.
The Master said: When Yin Qi is isolated and exhausted, and Yang Qi acts alone, fever, shortness of breath, and inner vexation occur. The hands and feet become hot, and there is a desire to vomit. This is called Dan Nüe (Febrile Malaria). If there is only heat without cold, the evil energy hides internally in the Heart and externally in the intermuscular spaces (Fen Rou), causing the muscles to waste away.
This text is largely consistent with the *Neijing*'s discussion on Dan Nüe. When Yin Qi is deficient, Yang Qi inevitably flares. Flaring damages Qi and consumes Spirit, resulting in shortness of breath and vexation. The four limbs are the root of all Yang channels; excessive Yang results in hot hands and feet. The desire to vomit is due to heat disturbing the Stomach. The evil hiding in the Heart: Dan is a Yang evil, and the Heart is a Yang organ. With Yang following Yang, the evil lodges externally in the Fen Rou, while its qi connects internally to the Heart. Muscle wasting occurs because muscles belong to Yin; extreme Yang leads to Yin consumption.
In Warm Malaria (Wen Nüe), the pulse resembles the normal state. There is no cold, only heat, severe joint pain, and occasional vomiting. Bai Hu Jia Gui Zhi Tang (White Tiger Plus Cinnamon Twig Decoction) is the primary treatment.
This differs from the *Neijing*'s description of Wen Nüe. The *Neijing* discusses etiology, whereas this text details the pulse and symptoms. Both Dan Nüe and Wen Nüe present with heat only (no cold) and vomiting, but their etiologies differ. Dan Nüe arises from pre-existing heat in the Lung combined with external contraction, resulting in an exterior-cold and interior-heat pattern. Because internal Yin Qi is deficient and cannot contend with Yang, chills do not occur. Wen Nüe involves an evil hidden in the Kidney, manifesting in spring and summer as latent Qi emerging outward. Cold accumulated over time transforms into heat, so chills also do not occur. The pulse resembling the normal state indicates the disease was not recently contracted, so the pulse reflects the patient's baseline. Severe joint pain and occasional vomiting occur because heat emerges from the Kidney, lodges externally in its paired area, and merges upward with the Yangming channel. Bai Hu Tang is sweet and cold to clear heat; Gui Zhi follows the pathological trend to vent the pathogen.
**Bai Hu Jia Gui Zhi Tang Formula:**
Zhi Mu (Anemarrhena Rhizome, 6 liang)
Shi Gao (Gypsum Fibrosum, 1 jin)
Gan Cao (Licorice Root, 2 liang, processed with fire)
Jing Mi (Glutinous Rice, 2 he)
Gui Zhi (Cinnamon Twig, 3 liang)
These five ingredients are boiled in ten dou of water until the rice is cooked and the decoction is ready. Strain. Take one sheng warm, three times daily.
When malaria presents with predominant chills, it is called Mu Nüe (Yang Malaria). Shu Qi San (Herba Patriniae Powder) is the primary treatment.
Predominant chills in malaria are not true cold; rather, Yang Qi is obstructed by phlegm-fluids and cannot reach the muscle surface, remaining latent in the Heart. The Heart is a Yang (Mu) organ, hence the name Mu Nüe. Shu Qi induces vomiting to expel malaria phlegm; once phlegm is gone, Yang Qi extends, and chills cease. Yun Mu (Cloud Mother/Mica) and Long Gu (Dragon Bone/Fossilized Bones) are used because Shu Qi's ascending action is fierce, and we fear it might disturb the Spirit and Qi of the Heart.
**Shu Qi San Formula:**
Shu Qi (Herba Patriniae, washed to remove fishy odor)
Yun Mu (Lepidolite/Mica, roasted for two days and nights)
Long Gu (Fossilized Bones, equal parts)
These three ingredients are pounded into a powder. Before the onset of the attack, take half a qian bi (measure) with Jiang Shui (fermented grain water).
**Appendix: Three Formulas from *Waitai Miyao***
**Muli Tang (Oyster Shell Decoction)**
Muli (Oyster Shell)
Ma Huang (Ephedra Stem, 4 liang each)
Gan Cao (Licorice Root, 2 liang)
Shu Qi (Herba Patriniae, 3 liang)
These four ingredients are boiled in eight sheng of water. First decoct Shu Qi and Ma Huang, removing the foam. Obtain six sheng of liquid. Add the remaining medicines and decoct to obtain two sheng. Take one sheng warm. If vomiting occurs, do not continue administration.
Note: This was appended by Sun Qi et al. in the Song Dynasty. It shares the intent of Shu Qi San but has stronger exterior-dispersing power. Zhao stated: Muli softens hardness and dissipates nodules; Ma Huang not only disperses cold but also vents Yang Qi, allowing it to circulate outward. When nodules dissipate and Yang Qi flows freely, the disease heals spontaneously.
**Chai Hu Qu Ban Xia Gua Lou Gen Tang (Bupleurum Decoction with Ban Xia Removed and Trichosanthes Root Added)**
Indicated for malaria with thirst, and also for Lao Nüe (Chronic/Wasting Malaria).
Chai Hu (Bupleurum Root, 8 liang)
Ren Shen (Ginseng Root)
Huang Qin (Scutellaria Root)
Gan Cao (Licorice Root, 3 liang each)
Gua Lou Gen (Trichosanthes Root, 4 liang)
Sheng Jiang (Fresh Ginger, 2 liang)
Da Zao (Jujube Fruit, 12 pieces)
These seven ingredients are boiled in twelve dou of water to obtain six sheng. Strain, then decoct again to obtain three sheng. Take one sheng warm, twice daily.
**Chai Hu Gui Jiang Tang (Bupleurum and Dried Ginger Decoction)**
Indicated for malaria with predominant chills and slight fever, or only chills without fever. One dose yields miraculous results.
Chai Hu (Bupleurum Root, 0.5 jin)
Gui Zhi (Cinnamon Twig, 3 liang)
Gan Jiang (Dried Ginger, 2 liang)
Gua Lou Gen (Trichosanthes Root, 4 liang)
Huang Qin (Scutellaria Root, 3 liang)
Gan Cao (Licorice Root, 2 liang, processed with fire)
Muli (Oyster Shell, 2 liang, processed)
These seven ingredients are boiled in ten dou of water to obtain six sheng. Strain, then decoct again to obtain three sheng. Take one sheng warm, three times daily. Mild irritability upon the first dose is expected; sweating upon subsequent doses indicates cure.
Zhao stated: This formula is similar to Mu Nüe but fundamentally different. In Mu Nüe, the evil lodges below the heart; here, Wind-Cold-Dampness Bi syndrome obstructs the muscle surface. Once the surface is Bi-obstructed, Yang Qi cannot circulate outward and becomes depressed within the Ying-Blood level. Yang Qi transforms into heat, and blood stasis forms, adhering to the site. When the Wei Qi circulates through the Yang levels twenty-five times and reaches this site, the disease manifests. The evil in the Ying level lacks the momentum to exit, and the Bi-obstructed Ying level does not emerge to contend with Yang, resulting in little or no fever. Therefore, Chai Hu is used as the Sovereign herb to vent the depressed Yang; Huang Qin as the Minister herb to clear semi-interior heat; Gui Zhi and Gan Jiang to unblock surface Bi; Gua Lou Gen and Muli to eliminate residual heat and resolve blood stasis; Gan Cao to harmonize the herbs and regulate Yin and Yang. Sweating disperses the Bi evil and moves blood heat, leading to recovery.
