未备。惟缪氏解用白虎以治暑证，而又初病即杂以牛膝、首乌等阴分之药，皆未可为轨则也。胎疟之称，尤为

裴兆期治一人，疟久不已。发时，必燥渴恣饮，更呕哕膨胀，面色黄瘁，此湿盛为疟之候也。医不审，日
以补中汤加知母、麦冬、乌梅、花粉等类治之益剧。裴以苍术三两，半夏、茯苓、泽泻、浓朴、陈皮、砂仁、
黄连各五钱作丸，每服二钱，日再进，旬余而安。夫服润剂而渴增，服燥药而渴反止，何也？流湿以润燥也。
凡久疟之人，必多黄涎恶水，聚于中宫，中宫湿甚则生热，热甚则生燥，所以作渴而多饮。流其湿则热不生，
热不生而燥自润矣。古人不我欺也。
黄锦芳治罗姓妇人疟疾，每于夜静即发，热多寒少，饮食如故，口渴不呕，热退无汗，发则喃喃错语，脉
则枯涩已极。知是邪入血分，若不从阴提出，必致阴分耗竭，致成不救。用当归二钱，川芎五分，熟地二钱，
知母一钱酒炒，红花五分，升麻三分，于未发时煎服，四五剂而愈。
陆六息体伟神健，从来无病。因忧劳而病疟，饮食减少，肌肉削瘦，形体困倦，时时嗳气，其候一日轻，
一日重，缠绵三月，大为所苦。此饥饱劳佚所感，受伤在阳明胃之一经。饮食减而大便艰涩者，胃病而运化之
机迟也。肌肉削瘦者，胃主肌肉也。形体困倦者，胃病而约束之机关不利也。时时嗳气者，胃中不和，而显晦
塞之象也。至于一日轻，一日重者，亦阳明胃经之候。经曰∶阳明之病，恶人与火，闻木声则惕然而惊。又曰∶
阳明之病，喜见火，喜见日月光。此正更实更虚之妙义，而与日轻月重之理相通者也。盖得病之始，邪气有余，
故恶人、恶火、恶木音者，恶其助邪也。及病久则邪去而正亦虚，故喜火、喜日月光者，喜其助正也。甲丙戊
庚壬，天时之阳，乙丁己辛癸，天时之阴。疟久食减，胃中正气已虚，而邪去未尽，是以值阳日助正，而邪
不能胜则轻，阴日助邪，而正不能胜则重也。今吃紧之处，全以培养中气为主。盖人虽一胃，而有三脘之分。
上脘象天，清气居多；下脘象地，浊气居多；而能升清降浊者，全赖中脘为之运化。病者，下脘之浊气，本当
下传也，而传入肠中则艰，不当上升也。而升至胸中甚易，以中脘素受饮食之伤，不能阻下脘浊气上乾清道耳。
故中脘之气旺，则水谷之清气上升于肺，而灌输百脉。水谷之浊气下达大肠，从便溺而消，胸中何窒塞之有哉？
所用六味丸，凝滞不行之药，大为胃病所不宜。今订理中汤一方，升清降浊为合法耳。
（前文内容）未记载完备。只有缪氏主张用白虎汤来治疗暑证，但在发病初期就混杂使用牛膝、首乌等属于阴分的药物，这些做法都不能作为准则。（“胎疟”这一称呼，更是世俗的说法，连魏君这样贤能的人都对此感到困惑，真是浅陋啊。）
裴兆期治疗一位患者，患疟疾日久不愈。发作时，必定烦躁口渴且大量饮水，随后出现呕吐呃逆、腹部胀满，面色萎黄憔悴，这是湿邪盛极导致疟疾的征候。医生没有仔细审察病情，每天使用补中益气汤加入知母、麦冬、乌梅、天花粉等药物治疗，结果病情反而加重。裴兆期用苍术三两，半夏、茯苓、泽泻、厚朴、陈皮、砂仁、黄连各五钱制成丸药，每次服用二钱，每天两次，十几天后病情安定。为什么服用滋润的药物而口渴增加，服用燥湿的药而口渴反而停止呢？这是因为通过利湿来达到润燥的效果。凡是患久疟的人，体内多有黄痰和恶臭的水液积聚在中焦脾胃，中焦湿气过重则产生热邪，热邪过盛则导致津液干燥，所以出现口渴且多饮的症状。疏通湿气则热邪不生，热邪不生则干燥自然得到滋润。古人确实没有欺骗我们。
黄锦芳治疗一位罗姓妇女的疟疾，每当夜深人静时发作，发热多而恶寒少，饮食正常，口渴但不呕吐，热退时无汗，发作时胡言乱语，脉象枯涩到了极点。判断为邪气侵入血分，如果不从阴分引出邪气，必然导致阴分耗竭，最终造成无法救治的局面。于是使用当归二钱，川芎五分，熟地黄二钱，知母一钱（酒炒），红花五分，升麻三分，在疟疾发作前煎服，四五剂后痊愈。
陆六息身体魁梧，精神健旺，向来没有疾病。因为忧愁劳累而患上疟疾，饮食减少，肌肉消瘦，形体困倦乏力，时常打嗝，症状表现为一天轻、一天重，缠绵三月，深受其苦。这是由于饥饱失调和劳逸不当所感，受伤部位在阳明胃经。饮食减少而大便干结难解，是因为胃病导致运化功能迟缓。肌肉消瘦，是因为胃主司肌肉。形体困倦，是因为胃病导致约束身体的机能不利。时常打嗝，是因为胃中不和，显现出气机壅塞的现象。至于症状一天轻、一天重，也是阳明胃经的病候。《内经》说：阳明病，厌恶人与火光，听到木器敲击的声音就会惊恐不安。又说：阳明病，喜欢见火光，喜欢见日月光。这正是虚实交替变化的精妙含义，与白天轻、晚上重的道理相通。大概患病之初，邪气有余，所以厌恶人、厌恶火光、厌恶木声，是厌恶它们助长邪气。等到病久，邪气已去但正气也虚弱，所以喜欢火光、喜欢日月光，是喜欢它们扶助正气。甲、丙、戊、庚、壬是天时的阳日，乙、丁、己、辛、癸是天时的阴日。疟疾日久饮食减少，胃中正气已经虚弱，而邪气尚未清除干净，所以在阳日正气得到天时之助，邪气不能战胜正气则症状减轻；在阴日邪气得天时之助，正气不能战胜邪气则症状加重。现在紧要之处，完全以培养中气为主。虽然人体只有一个胃，但有上脘、中脘、下脘三个部分的区别。上脘象征天，清气居多；下脘象征地，浊气居多；而能够升清降浊的，全赖中脘进行运化。病人的情况是，下脘的浊气本应当向下传导，但传入肠道则困难，不应当向上逆行，却很容易升至胸中，这是因为中脘平时受到饮食损伤，不能阻挡下脘浊气上犯清道。所以如果中脘之气旺盛，那么水谷的清气就能上升于肺，并灌输到全身血脉。水谷的浊气下达大肠，随大小便排出，胸中怎么会有窒塞的感觉呢？之前使用的六味地黄丸，是凝滞不行的药物，非常不适合胃病。现在重新拟定理中汤一方，以升清降浊为正确的治法。
(The preceding content) was not recorded in full. Only Miao advocated using Baihu Tang (White Tiger Decoction) to treat Summerheat syndromes, yet mixed herbs of the Yin aspect such as Achyranthis Bidentatae Radix (Niuxi, 牛膝) and Polygoni Multiflori Radix (Shouwu, 首乌) into the treatment from the onset of the disease. These practices cannot serve as standards. The term "Fetal Malaria" (Tai Nue, 胎疟) is even more of a vulgar notion; that even Wei, a virtuous scholar, was confused by it shows how shallow this view is.)
Pei Zhaoqi treated a patient who had suffered from malaria for a long time without resolution. Upon attack, the patient would invariably experience dryness and thirst, drinking copiously, followed by vomiting, hiccups, and abdominal distension, with a sallow and emaciated complexion. This is a sign of malaria caused by excessive Dampness. The physician failed to examine the condition carefully and prescribed Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) supplemented with Anemarrhenae Rhizoma (Zhimu, 知母), Ophiopogonis Radix (Maidong, 麦冬), Mume Fructus (Wumei, 乌梅), and Pseudostellariae Radix (Huafen, 花粉) daily, which only exacerbated the condition. Pei prescribed pills made of Atractylodis Rhizoma (Cangzhu, 苍术) three taels, and Pinelliae Rhizoma Preparatum (Banxia, 半夏), Poria (Fuling, 茯苓), Alismatis Rhizoma (Zexie, 泽泻), Magnoliae Officinalis Cortex (Houpo, 浓朴), Citri Reticulatae Pericarpium (Chenpi, 陈皮), Amomi Fructus (Sharen, 砂仁), and Coptidis Rhizoma (Huanglian, 黄连) each five qian. Each dose was two qian, taken twice daily. After more than ten days, the patient recovered. Why does thirst increase when taking moistening agents, but cease when taking drying agents? It is because draining Dampness achieves the effect of moistening. In cases of chronic malaria, there are often yellow phlegm and foul fluids accumulating in the Middle Jiao (Central Palace/Spleen-Stomach). When Dampness in the Middle Jiao is severe, Heat is generated; when Heat is severe, Dryness arises, leading to thirst and excessive drinking. By draining the Dampness, Heat is not generated; once Heat is absent, Dryness naturally resolves. The ancients did not deceive us.
Huang Jinfang treated a woman surnamed Luo for malaria. The attacks occurred every night when it was quiet, with more heat than chills. Her diet remained normal, she felt thirsty but did not vomit, and there was no sweat upon the subsidence of fever. During attacks, she spoke deliriously, and her pulse was extremely withered and choppy. He determined that the pathogenic factor had entered the Blood aspect. If the pathogen were not drawn out from the Yin, it would inevitably lead to the exhaustion of Yin fluids, resulting in an incurable state. He used Angelicae Sinensis Radix (Danggui, 当归) two qian, Chuanxiong Rhizoma (Chuanxiong, 川芎) five fen, Prepared Rehmanniae Radix (Shudi, 熟地) two qian, Anemarrhenae Rhizoma (Zhimu, 知母) one qian (stir-fried with wine), Carthami Flos (Honghua, 红花) five fen, and Cimicifugae Rhizoma (Shengma, 升麻) three fen. This was decocted and administered before the onset of the attack. After four or five doses, she was cured.
Lu Liuxi was robust and vigorous, having never been ill. Due to worry and overwork, he contracted malaria. His food intake decreased, muscles wasted away, his body felt heavy and fatigued, and he frequently belched. His symptoms fluctuated, being mild one day and severe the next, lingering for three months, causing him great suffering. This was caused by irregular diet and improper rest/exertion, injuring the Yangming Stomach Meridian. Decreased appetite and hard, difficult bowel movements indicate that stomach disease has slowed down the mechanism of transportation and transformation. Muscle wasting indicates that the Stomach governs the muscles. Bodily fatigue indicates that stomach disease has impaired the mechanisms that constrain the body. Frequent belching indicates disharmony in the Stomach, manifesting as a sensation of obstruction. As for the fluctuation between mild and severe days, this is also a manifestation of the Yangming Stomach Meridian. The Classics state: "Yangming disease involves aversion to people and fire, and hearing the sound of wood causes sudden fright." It also states: "Yangming disease likes fire, and likes sunlight and moonlight." This reflects the subtle meaning of alternating excess and deficiency, consistent with the principle of being milder during the day and heavier at night. Initially, when the disease began, the pathogenic factor was in excess; thus, aversion to people, fire, and wooden sounds stemmed from their perceived ability to aid the pathogen. Later, when the disease had lasted long, the pathogen had receded but the healthy Qi was also deficient; thus, liking fire and sunlight stemmed from their perceived ability to support the healthy Qi. Jia, Bing, Wu, Geng, Ren are the Yang days of heaven and earth; Yi, Ding, Ji, Xin, Gui are the Yin days. With prolonged malaria and reduced eating, the healthy Qi in the Stomach is already deficient, while the pathogen is not yet fully cleared. Therefore, on Yang days, the healthy Qi is assisted by heavenly Yang, so the pathogen cannot overcome it, resulting in milder symptoms; on Yin days, the pathogen is assisted by heavenly Yin, so the healthy Qi cannot overcome it, resulting in heavier symptoms. The current critical point lies entirely in cultivating the Middle Qi. Although there is only one Stomach, it is divided into the Upper, Middle, and Lower Guan (orifices/sections). The Upper Guan corresponds to Heaven, containing mostly clear Qi; the Lower Guan corresponds to Earth, containing mostly turbid Qi; and the ability to ascend the clear and descend the turbid relies entirely on the Middle Guan for transportation and transformation. In this patient, the turbid Qi of the Lower Guan should normally descend, but transmission into the intestines is difficult. It should not ascend, yet it easily rises to the chest because the Middle Guan has historically been injured by dietary factors and cannot block the turbid Qi of the Lower Guan from invading the Clear pathways. Therefore, if the Qi of the Middle Guan is prosperous, the clear Qi of water and grain ascends to the Lung and irrigates all vessels. The turbid Qi of water and grain descends to the Large Intestine and is eliminated through urination and defecation. How could there be any sensation of chest obstruction? The previously used Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) consists of cloying and stagnant medicines, which are highly unsuitable for stomach disease. I have now revised the prescription to Lizhong Tang (Regulate the Middle Decoction), which correctly ascends the clear and descends the turbid.
