凡是伤寒转变为疟疾的，是因为病初愈后，外邪尚未消散，脏腑真气尚且虚弱，又因劳累过度，导致阴阳二气相互争斗。阴气偏胜则出现发冷，阳气偏胜则出现发热。阴阳之气偏盛偏衰，就表现为忽冷忽热、发作有定时。一天发作两次的，出汗后必然痊愈。如果伤寒经过八九日，出现发热多而发冷少的情况，病人没有呕吐，大小便正常，这是将要自愈的迹象。或者出现阳明病的症状，烦躁发热、出汗，在傍晚时分（日晡）发热的，脉象浮的应当用解表法，脉象实的应当用攻里法。又有妇女热邪陷入血室，发热并且交替出现寒战的情况，应当详细辨别。
歌诀说：像疟疾一样的膀胱经证可用桂枝汤治疗；大小便正常且不呕吐的可用半夏、麻黄、桂枝；阳明腑实证需攻下，脉浮者需发汗；热邪入血室的，用小柴胡汤效果奇特。
所谓“似疟”，又称“疟状”，指发作和停止都有定时，不像典型的寒热往来那样或疏或密、或作或止没有规律。凡是感冒的人，忽然觉得毛发寒冷、大腿颤抖、筋骨关节拘挛、全身震颤、恶心不想吃东西，这种寒冷难以抵御，不久后又转而发热，这就是温疟。不必认为疟疾的脉象一定是弦脉，无论是洪数、紧实、虚缓还是刮涩，都可能是疟疾的表现，只要通过外在症状来辨别即可。用药固然有固定的法则，但小柴胡汤根据前述原则斟酌加减，也是灵活的方法。虽然血虚也能产生寒热，瘀血败血也会引起寒热，阴阳相争，虽然这一证候各有对应的方剂，但其中应当以川芎作为佐药。太阳经的似疟证，脉象洪大浮取，给予桂枝汤；若大小便正常，不呕吐，一天发作一两次，给予桂枝麻黄各半汤；其脉象微缓微浮，则是将要痊愈的征兆。阳明经的似疟证，烦躁发热出汗，傍晚发热，脉象浮虚，给予桂枝汤；脉象实，给予承气汤。妇女热邪陷入血室，血液必定凝结，表现如疟疾状的，以小柴胡汤主治。疟疾后出现的寒热，或者是潮热，看到病愈后精神昏沉的，调理各种疟疾通用二陈汤。发热多的，加川芎、前胡；发冷多的，加川芎、草果。

常山饮，此药南来，取效甚多，亦不吐人。（出自《保生返回论》）
药材：常山（二两，细锉）、鳖甲（醋炙紫色令净，二两）、芍药（三两，锉）、黄连（一两）、黄芩（一两）、柴胡（去苗，秤，二两）、甘草（一两，炙）、青蒿子（一两半，如无用茵陈蒿）。以上为粗末。每次服用五大钱，水二盏，乌梅半（个）两，同以慢火煮至一盏，滤去药渣，露一宿，于发作前一日进一服，于发作前一时再进一服，即愈。
Those whose typhoid fever transforms into malaria do so because, after the initial illness has subsided, external pathogens have not yet dissipated and the true qi of the internal organs remains deficient. Subsequent overexertion causes a struggle between yin and yang. When yin prevails, chills occur; when yang prevails, fever occurs. The predominance of either yin or yang results in alternating chills and fever with regular intervals of remission. If it occurs twice a day, sweating will lead to resolution. If, after eight or nine days of typhoid fever, there is more heat than cold, no vomiting, and normal bowel and bladder function, self-healing is anticipated. Alternatively, if symptoms of Yangming disease appear—such as irritability, fever, sweating, and afternoon (Ri Bu) fever—a floating pulse indicates the need for exterior-releasing methods, while a solid pulse indicates the need for interior-purging methods. In women, if heat enters the Blood Chamber (Xue Shi), causing fever with alternating chills, careful differentiation is required.
The verse states: For malaria-like conditions involving the Bladder meridian, Guizhi Tang (Cinnamon Twig Decoction) can be used; if bowel/bladder functions are normal and there is no vomiting, Banxia (Pinellia Rhizome), Mahuang (Ephedra Herb), and Guizhi (Cinnamon Twig) may be used; for Yangming excess requiring purgation, exterior release is needed for a floating pulse; for heat entering the Blood Chamber, Xiaochaihu Tang (Minor Bupleurum Decoction) yields miraculous results.
"Malaria-like" (Si Nüe), also known as "malaria pattern," refers to episodes that start and stop at fixed times, unlike typical alternating chills and fever which may vary in frequency or duration without regularity. In cases of common cold where one suddenly feels cold hair, trembling thighs, muscle and joint spasms, whole-body tremors, nausea, and loss of appetite, followed by intense chills that cannot be resisted and then turning into fever, this is termed Warm Malaria (Wen Nüe). One should not assume that all malaria presents with a string-taut (Xian) pulse; whether the pulse is surging-rapid (Hong Shu), tight-solid (Jin Shi), deficiency-slow (Xu Huan), or scraping-rough (Gua Se), it may indicate a malaria pattern, distinguished by external signs. While there are standard treatments, modifying Xiaochaihu Tang (Minor Bupleurum Decoction) according to these principles is also a flexible approach. Although blood deficiency can generate chills and fever, and stagnant blood can also cause them, and despite different formulas for each aspect of yin-yang conflict, Chuanxiong Rhizome (Chuanxiong) should generally serve as an assistant herb.
For Taiyang (Greater Yang) malaria-like patterns with a surging-floating pulse, administer Guizhi Tang (Cinnamon Twig Decoction); if bowel/bladder functions are normal, no vomiting, and attacks occur once or twice daily, Guizhi Mahuang Ge Ban Tang (Cinnamon Twig and Ephedra Half-Decoction) is indicated; a slightly slow and slightly floating pulse suggests impending recovery. For Yangming (Bright Yang) malaria-like patterns with irritability, fever, sweating, and afternoon fever, a floating-deficient pulse warrants Guizhi Tang (Cinnamon Twig Decoction), while a solid pulse warrants Chengqi Tang (Bowel-Purging Decoction). For women with heat entering the Blood Chamber, blood coagulation likely occurs, presenting like malaria; Xiaochaihu Tang (Minor Bupleurum Decoction) is the primary treatment. For post-malaria chills and fever, or tidal fever, accompanied by lethargy after recovery, Erchen Tang (Two-Aged Decoction) is universally applicable for regulating various malaria types. Add Chuanxiong Rhizome (Chuanxiong) and Qianhu (Peucedani Radix) for more heat; add Chuanxiong Rhizome (Chuanxiong) and Caoguo (Tsaoko Fruit) for more cold.
