胜加桂、姜。拟初、中、末疟门用药于下∶
初病暑风湿热疟药∶胸膈痞闷，枳壳、桔梗、杏仁、浓朴、（四味最宜。）栝蒌皮、山栀子、香豆豉。头
痛，宜辛凉轻剂，连翘、薄荷、赤芍、羚羊角、蔓荆子、滑石，重则用石膏。口渴用花粉，烦渴用竹叶石膏汤。
热甚则用黄连、黄芩、山栀。
夏季牙痛属湿，羌、防辛温宜忌，宜用木防己、蚕砂。
暑热邪伤，初在气分，日多不解，渐入血分，反渴不多饮，唇舌绛赤，芩、连、膏、知不应，必用血药，
量佐清气热，一味足矣。轻则用青蒿、丹皮、（汗多忌。）犀角、竹叶心、元参、鲜生地、细生地、木通、淡竹叶。
若热久痞结，泻心汤选用。
又夏月热久伤血，最多蓄血一证，谵语昏狂，看法以小便清长者，大便必黑为是，桃仁承气汤为要药。
幼稚疟久，面肿腹膨，泄泻不欲食，或囊肿或跗肿，必用东垣益气以升阳。倘脾消败，前方不应，用理中
汤，或钱氏益黄散得效。二三日须投五苓散，一二日再与异功散，参苓白术之类必全好。徐忠可注《金匮》有

人参、生姜，曰露姜饮，一以固元，一以散邪，取通神明去秽恶之意。总之，久疟气馁，凡壮胆气，皆可止疟，
未必真有疟鬼。又疟邪既久，深入血分，或结疟母，鳖甲煎丸设用煎方，活血通络可矣。

马元仪治金氏子，寒热如疟，两脉弦虚无力。脉弦为风发，脉虚为气少。正虚则外风得以袭入，乃为寒热，
不当与气实有余者同治。乃用补正散邪一法，用人参、桂枝、干姜、肉桂、半夏、广皮、炙草等，调理数月而安。
叶天士说：疟疾大多因暑邪引发，医书虽然记载有痰、食、寒、热、瘴疠等不同类型。但小儿的疟疾，都因为脾胃受病所致。然而小儿正气怯弱、精神虚弱，初起发病时多表现为惊风、痫证、厥逆等症状，在夏秋季节，绝对不能误认为是惊风或痫证。大凡疟症，必须区分属于十二经中的哪一经，这与咳嗽病症的分析原则相当。如果儿科医生庸俗浅薄，仅用小柴胡汤去掉人参，或者使用香薷、葛根之类的药物，却不知道柴胡会扰动肝阴，葛根会耗竭胃中津液，导致病情变化屡见不鲜。小儿体质属纯阳，暑邪属于热气，症状必定是热象多于烦渴。若邪气从肺脏感受，使用桂枝白虎汤，服用两次必然痊愈。如果有冷食停滞不化，出现足太阴脾病的见证，初期可用正气散，或使用辛温药物，如草果、生姜、半夏之类。医书说草果治疗太阴经独盛的寒邪，知母治疗阳明经独盛的熱邪。疟疾日久导致面色枯槁、唇色苍白、汗多体虚，必须使用四兽饮，即六君子汤加上草果、生姜、大枣、乌梅。若是阴虚内热，必须使用鳖甲、何首乌、知母，但若大便渐趋溏泄者则忌用。久疟导致营血受损，寒邪盛者加用桂枝、生姜。拟定初、中、末三期疟疾门用药如下：
初期暑风湿热疟药方：胸膈痞闷，用枳壳、桔梗、杏仁、厚朴（这四味药最合适），栝蒌皮、山栀子、香豆豉。头痛，宜用辛凉轻剂，如连翘、薄荷、赤芍、羚羊角、蔓荆子、滑石，重症则用石膏。口渴用天花粉，烦渴用竹叶石膏汤。热势甚重则用黄连、黄芩、山栀。
夏季牙痛属湿邪，羌活、防风等辛温药物应当禁忌，宜用木防己、蚕砂。
暑热邪气伤人，初期在气分，日子久了不解，逐渐进入血分，反而口渴但不想多喝水，嘴唇和舌头呈绛红色，此时黄芩、黄连、石膏、知母无效，必须使用治血分的药物，稍微佐以清气分之热的药物即可，一味药就足够了。轻症用青蒿、丹皮（出汗多者忌用）、犀角、竹叶心、玄参、鲜生地、细生地、木通、淡竹叶。如果热邪日久导致痞结，选用泻心汤。
另外，夏季热邪日久伤血，最多见蓄血这一证候，出现谵语、昏狂，诊察方法看小便清长通畅的，大便必定发黑，桃仁承气汤是关键药物。
小儿疟疾日久，面部浮肿、腹部膨隆、泄泻不想进食，或者睾丸肿胀或足背肿胀，必须使用李东垣的益气升阳法。倘若脾气消败，前方无效，使用理中汤，或钱乙的益黄散可获效。二三天须投五苓散，一两天后再给予异功散，参苓白术散之类的方剂必能全愈。徐忠可注释《金匮要略》时说：幼儿尚未进食谷物的，患疟疾日久不止，用冰糖浓汤。我尝试果然有效。
疟疾多用乌梅，这是取酸味以泄肝木、安脾土的意思。使用常山、草果，是为了劫夺太阴经的寒邪，因为常山药性极善走窜，使两种邪气不能相并。使用人参、生姜，称为露姜饮，一是为了固护元气，一是为了发散邪气，取通达神明、去除秽恶之意。总之，久疟导致气馁，凡是能壮胆气的药物，都可以止疟，未必真有疟鬼。又疟邪既然日久，深入血分，或者结成疟母，鳖甲煎丸如果改用煎剂，活血通络就可以了。
万密斋治疗一个患儿，一岁半得疟疾，两天发作一次，久治不愈，身体黄瘦，面部浮肿，腹胀，用平疟养脾丸治疗而痊愈。药物组成：人参、白术、茯苓、甘草、当归、川芎、陈皮、半夏、苍术、厚朴、柴胡、黄芩、猪苓、泽泻、草果、常山、青皮、辣桂、鳖甲各等分，在五月初五或三元八节、天月德日配制，酒煮，曲糊制成梧桐子大小的丸药，陈皮汤送服。
另一个患儿患疟疾，医生使用截疟药，其中含有砒霜丹药，三次截疟后，遂变成疳疟。他的父亲懊悔前医用药错误。万密斋用平疟养脾丸治疗疟疾，集圣丸治疗疳积，调理一个月而痊愈。集圣丸组成：芦荟、五灵脂、夜明砂、缩砂仁、橘皮、青皮、蓬术、木香、黄连、使君子、虾蟆、猪胆汁。将药混合入膏制成粉末。
又一个患儿患疟疾，一天发作一次，万密斋用家传斩鬼丹截断疟疾，停止三天后又发作一次。再次截断，正值三四天后又发作。他的父亲奇怪地询问原因，当时正值六七月份枣子成熟，怀疑孩子一定吃了生枣，所以停止服药后就复发了。询问后确实如此，于是禁止吃枣，先用胃苓丸，调理三天（平胃散由苍术、陈皮、厚朴、甘草组成，合以五苓散由茯苓、猪苓、白术、泽泻、桂枝组成，名为胃苓丸），再用斩鬼丹截断便痊愈了。五月五日午时，用黄丹研磨，独头大蒜研磨成泥同杵，众人手搓成丸。根据孩子大小，发作日五更天时，取长流水面向东方吞服。
汪氏的儿子七岁，患疟疾三年，众医无效。万密斋观察其外部征候，面色白，山根带青色，腹部大而坚硬。这是久疟成癖，癖积会导致潮热，应当给予补脾消癖的药物，疟热自然消除。遗憾的是没有九肋鳖甲，汪氏求得之后，因此立一方，用人参、白术、青皮、陈皮、三棱、莪术、木香、砂仁、当归、川芎、黄连、柴胡、鳖甲研为粉末，神曲糊丸。炒米煎水，每日三次服用，调理五十多天而安定。
李氏七岁女孩，先患外感，后变为疟疾，因为使用截疟药，变作痢疾。到了冬天，痢疾虽止，疟疾却更加严重。万密斋观察其外部征候，大骨高起，大肉陷下，头发稀疏眼睛凹陷，面色黄鼻子干燥，不思饮食，只吃莲肉，这是内伤脾虚疳劳症。医生都说不可治，万密斋说：可以治，到春天一定会好。用集圣丸一料，次年二月果然平安。
王氏之子患疟疾，三天发作一次，用胃苓丸合小柴胡汤方，制成丸药服用。起初三天发作一次，后来间日发作，再后来一日发作。初发于午后，逐渐移于辰时。问他说：连续几天服药，疟疾发作反而频繁是怎么回事？回答说：这是疟疾将要消退的迹象。大概疟疾三天发作一次，邪气深，难治愈；一日发作一次，疟气浅，容易痊愈。午后发作，邪在阴分，难治愈；午前发作，邪在阳分，容易痊愈。现在从三日移至一日，从阴分移至阳分，所以说将要消退的迹象。当时有位丁姓医生听到他的说法，笑着说：哪有这么多议论？我有秘方，治疟如神。于是求治，不知道他用了什么药。从此仍然三日发作一次，发作于酉时，到次日巳后才退去。万密斋仍为他调理一个月而痊愈。
孙文垣治疗丁氏之子，才两岁，患疟母，上壅咳嗽，每午后发热，至子丑时才退，终日啼哭不止，鹅口疮白屑，神气大弱。又在痘疹后遍身疮疥未愈，众医有的灸之，有的刺之，有的用膏药贴之，种种施治都不见效。孙文垣说：乳下婴儿，脏腑脆薄，不可乱攻乱补，人参、麦冬足以增加其咳嗽，灸刺恰好惊吓其神志，怎么能取效？教导用白术、鳖甲各一钱五分，青蒿、麦芽、陈皮各八分，乌梅一个，贝母、知母各六分，甘草三分，八帖全愈。
水鉴仙人治疗百日儿疟疾歌诀说：疟疾是风寒热邪攻击，直须用术治疗以免落空，常山刻成人形，钉在孩子的生气宫。如果是金命人，金长生在巳，就钉在巳位上；木命人，钉在亥位上；火命人，钉在寅位上；水命人，钉在申位上。常山是截疟的药物。
万密斋的外孙不满周岁，因伤寒，发间日疟，在子丑时发作，发作时抽搐强直，咬牙呻吟，大便黄绿，用力排出。用嘴吸母亲的乳头，得到乳汁即停止。疟疾后出汗，心下跳动，腹中鸣响，头顶微热，不到十天就成了疳积。面色㿠白，囟门凹陷头发稀疏，孩子逐渐消瘦。这是先受暑湿，暑邪则为疟疾，湿邪则为痰饮。又伤饮食，脾土衰败而肝木旺盛，疟疾称为食疟，疳积称为食疳。用加减当归龙荟丸，加味参苓白术散。其母亲用四物汤，加柴胡、升麻、麦冬、木通、酒芩、桔梗各五分，薄荷七分，灯草水煎服。
一个患儿患疟疾，医生用柴胡汤投喂无效，乃用平疟养脾丸而痊愈。
一个患儿久疟成癖，因癖积生热，或三五日内发作一次，发作时其余日子不停止。常在申酉时，但不寒颤，又微恶寒，即发热，热也不很严重，发作过后不渴，不头痛。用消癖丸、平疟养脾丸交替服用，半年而痊愈。
马元仪治疗金氏之子，寒热如疟，两脉弦虚无力。脉弦为风邪发作，脉虚为气少。正气虚弱则外风得以袭入，乃为寒热，不应当与气实有余者同样治疗。乃用补正散邪一法，用人参、桂枝、干姜、肉桂、半夏、广皮、炙甘草等，调理数月而安定。
Ye Tianshi said: Malaria is mostly caused by summerheat pathogen. Although medical texts record differences such as phlegm, food stagnation, cold, heat, and miasma, malaria in infants and children is primarily due to disease of the spleen and stomach. However, since their vital qi is deficient and spirit is weak, initial symptoms often manifest as fright convulsion (Jing Xian), epilepsy, or reversal syndrome (Jue Ni). During summer and autumn, these must not be mistaken for fright convulsion or epilepsy. Generally, malaria cases must be differentiated according to the twelve meridians, similar to the analysis of cough syndromes. If pediatric practitioners are mediocre, using Xiao Chai Hu Tang (Minor Bupleurum Decoction) with Ginseng removed, or herbs like Xiang Ru (Moslae Herba) and Ge Gen (Puerariae Radix), they fail to realize that Chai Hu (Bupleuri Radix) disturbs Liver Yin, and Ge Gen exhausts Stomach fluids, leading to frequent changes in the condition. Children possess a "pure yang" constitution; summerheat is a hot pathogen, so symptoms inevitably present with more heat than irritability and thirst. If the pathogen enters from the Lung, Gui Zhi Bai Hu Tang (Cinnamon Twig and White Tiger Decoction) will cure it after two doses. If there is stagnation of cold food with manifestations of Foot-Taiyin Spleen disease, initially use Zheng Qi San (Regular Qi Powder) or acrid-warm herbs such as Cao Guo (Tsaoko Fructus), Sheng Jiang (Zingiberis Rhizoma Recens), and Ban Xia (Pinelliae Rhizoma). Medical texts state that Cao Guo treats exclusive cold of the Taiyin, and Zhi Mu (Anemarrhenae Rhizoma) treats exclusive heat of the Yangming. In chronic malaria with sallow complexion, white lips, profuse sweating, and weakness, Si Shou Yin (Four Beasts Infusion) must be used, which is Liu Jun Zi Tang (Six Gentlemen Decoction) plus Cao Guo, Sheng Jiang, Da Zao (Jujubae Fructus), and Wu Mei (Mume Fructus). For yin deficiency with internal heat, Bie Jia (Testudinis Carapax et Plastrum), Shou Wu Di (Polygoni Multiflori Preparata Radix), and Zhi Mu are required; however, they are contraindicated if stools become loose. In chronic malaria damaging Ying blood, if cold predominates, add Gui Zhi (Cinnamomi Ramulus) and Sheng Jiang. The following medications are proposed for the early, middle, and late stages of malaria:
For early-stage summerheat-dampness-wind-heat malaria: For chest and diaphragm fullness and oppression, use Zhi Ke (Aurantii Fructus), Jie Geng (Platycodonis Radix), Xing Ren (Armeniacae Semen Amarum), and Hou Po (Magnoliae Officinalis Cortex) (these four are most suitable), Gua Lou Pi (Trichosanthis Pericarpium), Shan Zhi Zi (Gardeniae Fructus), and Xiang Dou Chi (Sojae Semen Praeparatum). For headache, use light acrid-cool agents like Lian Qiao (Forsythiae Fructus), Bo He (Menthae Haplocalycis Herba), Chi Shao (Paeoniae Radix Rubra), Ling Yang Jiao (Capricornis Cornu), Man Jing Zi (Vittariae Spica), and Shi Gao (Gypsum Fibrosum) for severe cases. For thirst, use Hua Fen (Trichosanthis Radix); for irritability and thirst, use Zhu Ye Shi Gao Tang (Bamboo Leaf and White Tiger Decoction). For intense heat, use Huang Lian (Coptidis Rhizoma), Huang Qin (Scutellariae Radix), and Shan Zhi Zi.
For summer toothache due to dampness, acrid-warm herbs like Qiang Huo (Notopterygii Rhizoma et Radix) and Fang Feng (Saposhnikoviae Radix) should be avoided; instead, use Mu Fang Ji (Stephaniae Tetrandrae Radix) and Can Sha (Bombyx Batryticatus).
When summerheat-pathogen injures the body, initially affecting the Qi level, if unresolved over days, it gradually enters the Blood level. This presents as thirst but little desire to drink, crimson lips and tongue. When Huang Qin, Huang Lian, Shi Gao, and Zhi Mu are ineffective, blood-invigorating herbs must be used, slightly assisted by one herb clearing Qi-level heat. For mild cases, use Qing Hao (Artemisiae Annuae Herba), Dan Pi (Moutan Cortex), Xi Jiao (Rhinocerotis Cornu - *note: substitute with water buffalo horn in modern practice*), Zhu Ye Xin (Phyllostachys Viridis Folium), Xuan Shen (Scrophulariae Radix), Xian Sheng Di (Rehmanniae Radix Recens), Xi Sheng Di (Rehmanniae Radix Preparata), Mu Tong (Akebiae Caulis), and Dan Zhu Ye (Lophatheri Herba). If heat persists causing stagnation, select Xie Xin Tang (Drain the Epigastrium Decoction).
Furthermore, prolonged summerheat injuring blood often results in Blood Stasis syndrome, presenting with delirium, coma, and mania. Diagnosis involves observing clear and copious urine, indicating black stools; Tao Ren Cheng Qi Tang (Peach Kernel and Major Order the Qi Decoction) is the essential medicine.
In chronic childhood malaria with facial edema, abdominal distension, diarrhea, anorexia, testicular swelling, or dorsal foot edema, Li Dongyuan’s method of tonifying Qi and raising Yang must be used. If Spleen Qi fails and previous formulas are ineffective, use Li Zhong Tang (Regulate the Middle Decoction) or Qian Yi’s Yi Huang San (Benefit the Spleen Powder) for efficacy. After two to three days, administer Wu Ling San (Five-Ingredient Powder with Poria); after one to two days, give Yi Gong San (Extraordinary Efficacy Powder) or Shen Ling Bai Zhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) to ensure complete recovery. Xu Zhongke, annotating the *Jin Gui Yao Lue*, stated: For infants who have not yet consumed grain and suffer from persistent chronic malaria, use strong sugar water decoction. My trials confirmed its efficacy.
Malaria treatment often uses Wu Mei (Mume Fructus) to employ sour flavor to drain Liver Wood and calm Spleen Earth. Using Chang Shan (Dichroae Radix) and Cao Guo is to劫 (rob/seize) Taiyin cold; Chang Shan moves rapidly, preventing the two pathogens from combining. Using Ren Shen (Ginseng Radix) and Sheng Jiang constitutes Lu Jiang Yin (Dew Ginger Drink), one to secure Yuan Qi and one to disperse pathogen, aiming to unblock the Spirit and remove filth. In summary, chronic malaria depletes Qi; any herb that strengthens Gallbladder Qi can stop malaria; it is not necessarily due to a "malaria ghost." Furthermore, if malaria pathogen lingers long and enters the Blood level, forming a Malaria Mass (Nu Mu), Bie Jia Jian Wan (Turtle Shell Decoction Pill) can be used as a decoction to invigorate blood and unblock collaterals.
Wan Mizhai treated a child of eighteen months with malaria occurring every two days, persisting despite treatment, presenting with yellow emaciation, facial edema, and abdominal distension. He cured it with Ping Mie Yang Pi Wan (Level Malaria and Nourish Spleen Pill). Ingredients: Ren Shen, Bai Zhu (Atractodis Macrocephalae Rhizoma), Fu Ling (Poria), Gan Cao (Glycyrrhizae Radix et Rhizoma), Dang Gui (Angelicae Sinensis Radix), Chuan Xiong (Chuanxiong Rhizoma), Chen Pi (Citri Reticulatae Pericarpium), Ban Xia (Pinelliae Rhizoma), Cang Zhu (Atractodis Rhizoma), Hou Po, Chai Hu (Bupleuri Radix), Huang Qin, Zhu Ling (Poria), Ze Xie (Alismatis Rhizoma), Cao Guo, Chang Shan, Qing Pi (Citri Reticulatae Pericarpium Viride), La Gui (Cinnamomi Cortex), and Bie Jia in equal parts. Prepared on the 5th day of the 5th lunar month or during specific auspicious days, boiled in wine, formed into pills the size of hemp seeds with Qu paste, taken with Chen Pi decoction.
Another child developed malaria; the physician used antimalarial drugs containing Arsenic (Pi Dan). After three courses, it transformed into Gan Malaria (Childhood Malnutrition Syndrome associated with Malaria). The father regretted the error. Wan Mizhai treated the malaria with Ping Mie Yang Pi Wan and the Gan syndrome with Ji Sheng Wan (Accumulation-Sage Pill), resulting in recovery after one month of regulation. Ji Sheng Wan ingredients: Lu Hui (Aloe), Wu Ling Zhi (Trogopterori Faeces), Ye Ming Sha (Typhlopidae Oculus), Suo Sha (Amomi Fructus Rotundus), Ju Pi (Citri Reticulatae Pericarpium), Qing Pi, Peng Zhu (Curcumae Rhizoma), Mu Xiang (Aucklandiae Radix), Huang Lian, Shi Jun Zi (Quisqualis Fructus), Ha Ma (Bufo Skin), and Zhu Dan (Porcine Bile). Mixed into paste and powdered.
Another child had malaria once daily. Wan used his family's Zhán Guǐ Dan (Ghost-Slaying Pill) to intercept it, stopping for three days before recurrence. Intercepting again, it recurred after three to four days. The father asked why. At that time, dates were ripe in July; he suspected the child ate raw dates, causing recurrence upon stopping medication. Inquiry confirmed this. They banned date consumption, first regulating with Wei Ling Wan (Stomach-Ling Pill) for three days (Ping Wei San combined with Wu Ling San), then using Zhán Guǐ Dan to intercept, resulting in cure. On the 5th day of the 5th lunar month at noon, use Huang Dan (Lead Monoxide) ground with single-clove garlic into a paste, rolled into pills by many hands. Size appropriate to the child; take at dawn on the day of fever with flowing water facing east.
Wang’s son, seven years old, suffered malaria for three years with no effect from other physicians. Wan observed pale complexion, bluish root of the nose, and firm abdominal distension. This was chronic malaria forming a mass (Pi), causing tidal fever. Treatment should tonify Spleen and dissipate masses; malaria heat would naturally resolve. Lacking nine-ribbed Bie Jia, Wang obtained some. Formula: Ren Shen, Bai Zhu, Qing Pi, Chen Pi, San Leng (Sparganii Rhizoma), E Zhu (Curcumae Rhizoma), Mu Xiang, Sha Ren (Amomi Fructus), Dang Gui, Chuan Xiong, Huang Lian, Chai Hu, Bie Jia powdered, pillified with Shen Qu paste. Taken with fried rice decoction, three times daily. Regulated for over fifty days until stable.
Li’s seven-year-old daughter initially had external contraction, transforming into malaria. Due to antimalarial interception, it transformed into dysentery. By winter, dysentery stopped, but malaria worsened. Wan observed prominent bones, sunken muscles, sparse hair, sunken eyes, sallow face, dry nose, anorexia, and preference for lotus seeds. This was internal injury Spleen deficiency Gan Lao (Consumption Syndrome). Physicians deemed it incurable, but Wan predicted recovery by spring. One course of Ji Sheng Wan resulted in health by February of the next year.
Wang’s son had malaria every three days. He took Wei Ling Wan combined with Xiao Chai Hu Tang pills. Initially every three days, then every other day, then daily. Initial onset shifted from afternoon to Chen hour (7-9 AM). Asked why frequency increased despite medication, Wan replied: This indicates the malaria is retreating. Three-day intervals indicate deep pathogen, hard to cure; daily intervals indicate shallow pathogen, easy to cure. Afternoon onset indicates pathogen in Yin level, hard to cure; morning onset indicates pathogen in Yang level, easy to cure. Shift from three days to one day, and from Yin to Yang, indicates retreat. Physician Ding laughed, claiming secret remedies. He sought treatment, unknown ingredients. Recurrence remained every three days at You hour (5-7 PM), resolving after Si hour (9-11 AM). Wan regulated him for a month until cured.
Sun Wen Yuan treated Ding’s son, two years old, with Malaria Mass (Nu Mu), upper congestion cough, afternoon fever resolving at Zi-Chou hours (11 PM-3 AM), constant crying, thrush, and weak spirit. Post-smallpox skin sores persisted. Other treatments (moxibustion, acupuncture, plasters) failed. Sun stated: Infants have fragile organs; do not attack or tonify blindly. Ren Shen and Mai Dong increase cough; moxa/acupuncture startles the spirit.
