涂蔚生曰∶周梦觉之疟疾症治，固已精美完善。然考其所本，多半出自仲景。不过仲景简而赅，而梦觉繁而
详。实则本仲景之法以为治，即无不治之疟，亦无治不能愈之疟。盖疟，系风寒由外之油膜，以入内之油膜者。而
仲景之治疟，则根据少阳以为治，必使邪之由外而入者，仍由外而出。今人不查此中原理，动以截止为能事，每至旋愈
旋复，即以其不能根本解决也。予每以仲景之法治疟，凡遇疟之一二剂不能全愈者，必劝其多服数剂，使其卒归于
愈，愈而不复。今将其原文摘入，虽为治疟者之备考，夫亦曰存古云耳。
张仲景曰∶疟脉自弦，弦数者，多热；弦迟者，多寒；弦小
紧者下差。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，以饮食消息之。
唐容川曰∶《内经》言疟邪藏于风府，旁连募原。募即膜也，膜之原在脐下，即三焦之连网矣。三焦、膀胱
皆肾之府，三焦为阳府，而化水行于里，则为小便；膀胱为阴府，而化气于表，则为卫气。《内经》就疟所发言，
责在卫气，故邪在太阳之风府。仲景就疟之所留言，故责在三焦膜原。是以疟症，未有小水清利者，三焦之决渎病也。
仲景以少阳立论，其义在此，正与《内经》互相发明。后人不知三焦，至谓仲景之证与《内经》不合，谬矣。
张仲景曰∶病疟以月一日发，当十五日愈。设不瘥，当月尽解。如其不瘥，当云何？曰此结为 瘕，名曰疟母。
当急治之，宜鳖甲煎丸。

诸药煎为丸如梧子大，空心服七丸，日三服（《千金》用鳖甲十二片，又有海藻三分，大戟一分。无鼠妇，赤硝二味）
唐容川曰∶夫疟邪本伏于营血之中，卫气会而始发，故久则营血结聚而为疟母。卫气不通，而为留痰。是血
为疟母之主，痰属卫气所生，乃疟母之兼有者也。故治疟母，以攻利营血为主，而行痰降气为辅。知此则知仲景此
方，破血之药，所以独多，总是治营以通卫也。
涂蔚生曰∶各家之对于疟症，所以先寒后热，以及结成疟母
之理，虽不乏精细辨论，而能理由充足，不致令人疑虑者，殊少其人。以余度之，疟症即系邪气伏居少阳油膜之
上，而下焦化生之气，亦必须循油膜上行而外达，以为护卫。今以邪气之阻，不得外达，而为护卫，故始而恶寒
特甚。迨至邪正交战既久，纷争已毕，终系邪气势弱，而正气势强。孰知正气愈郁结，而勃发愈猛，故继而发热特
甚。设使邪随汗出，则疟可冀愈。否则，病患设为健壮，化生正气迅利，则正气之团结亦速，出与邪争亦急。今病
者之体有强弱，化生之气有迟缓，故疟有一日一发，间日一发。营血之行，以卫气为转移，今卫气屡为邪气郁阻，
而营血不能随其郁阻，经火炼以为郁滞，而为疟母焉。夫疟母名者，以邪气纵随正气纷争尽出。而此血之凝滞，
与邪伏居油膜无异，仍可使疟疾发生焉。故主鳖甲 虫大黄桃仁等味，攻血者，以攻利之。浓朴葶苈等味，理气
者，以疏散之。然犹虑邪未尽除也，仍用柴胡桂枝以解之，人参以托之。血虚受伤也，兼用阿胶白芍以固之。余
则清热涤水之味，务使其邪气尽除，不至血痰交结而为疟母焉。此说此见，不知有合圣意否，尚希国内高明医士
随时教正是幸。
张仲景曰∶阴气孤绝，阳气独发，则热而少气、烦冤，手足热而欲吐，名曰瘅疟。若但热不寒者，邪气内藏于
心，外舍分肉之间，令人消瘦肌肉。
唐容川曰∶阴气指少阴心肾也。心肾之阴虚，故热而少气，心中烦冤。邪气能入于心，而内藏于心，皆少阴阴
气孤绝之证也。阳气指太阳膀胱也，水中之阳，化气为热，以卫周身。今独有阳气则纯热，合于阳明，则为手足热。
合于三焦，则欲呕。外合于腠理分肉之间，则令肌肉消烁。治少阴，宜鸡子黄汤。治太阳，宜白虎汤。后世如清
瘟败毒饮一方，可以兼治。
按《史记·仓公传》风瘅客脬，言瘅邪客居膀胱。此瘅疟亦发于膀胱，与牡疟正相对，牡疟是邪在心也。
张仲景曰∶温疟者，其脉如平，身无寒但热，骨节烦疼。时
呕，白虎加桂枝汤主之。
白虎汤加桂枝
知母（一钱） 石膏（一钱） 甘草（一钱） 粳米（一钱） 桂枝（七分）
唐容川曰∶身无寒但热，为白虎汤之正证。加桂枝者，以有骨节烦疼症，则有伏寒在于筋节，故用桂枝以逐
之也。
张仲景曰∶疟多寒者，名曰牡疟，蜀漆散主之。

Zhou Mengjue said: Scholars study for ten years and probe into principles for another ten years, believing themselves to have mastered the essence of medicine. Yet when they treat patients, their actions often contradict reality; they either blame pharmacies for selling fake drugs or attribute the illness to its genuine causes. It is useless to argue with them strongly; let us try testing them by treating malaria. Malaria is a superficial and obvious disease, most capable of verifying a physician's competence. Those who use harsh drugs to forcibly stop symptoms and achieve success by luck are not discussed here. If one has a dignified formation and an upright army, winning every battle, then one can hang a medical pot in the city and carry a medicine basket in the countryside; if treatments prove ineffective and prescriptions are changed repeatedly, even discarding ancient texts as chaff and vainly reading ten thousand volumes, the hard work at the cold window and lamp desk would have wasted ten years. The Classic says: "Pathogenic factors lodge in the Fengfu point (Wind Palace acupoint), descend along the spine, and their qi ascends, emerging from the Quepen point (Missing Basin acupoint) after nine days." Reading this scripture, I understood why the pulse in malaria is wiry (Xian). Inside the body shell but outside the viscera lies the half-exterior half-interior region, where pathogens reside; thus the pulse should be wiry, similar to Shaoyang diseases. Therefore, wind has no fixed palace; the site of invasion becomes the palace, such as the occipital bone. The meridians of the three Yangs all ascend to the head. The Yangming meridian runs from the hairline to the forehead and skull; when pathogenic factors merge with Yangming, it causes headache, severe aversion to cold, and later fever, constituting Yangming malaria. The Shaoyang meridian ascends to the temporal angle and descends behind the ear; when pathogens merge with Shaoyang, it causes headache, mild aversion to cold, mild fever, and fear of people, constituting Shaoyang malaria. As for the Taiyang meridian, it enters the brain from the vertex, emerges separately down the neck, passing exactly through Fengfu; thus it causes headache, heavy waist, heavy body, and cold starting from the back. Hence, invasions of the Yang meridians are mostly Taiyang malaria, affecting the occipital bone. The meridians of the three Yins all originate from the Foot-Taiyang bladder meridian, ascending through the inner knee and thigh into the abdomen. When pathogens merge with Taiyin, it causes weak legs, loss of appetite, and alternating chills and fever, constituting Taiyin malaria. The Jueyin liver meridian enters the pubic region and surrounds the genitalia; when pathogens merge with Jueyin, it causes weak legs, lower abdominal fullness, and difficult urination, constituting Jueyin malaria. Regarding the Shaoyin kidney meridian, it runs straight up the posterior aspect of the thigh along the spine, right at Fengfu; thus it causes weak legs, severe vomiting, and alternating chills and fever with more heat than cold. Hence, invasions of the Yin meridians are mostly Shaoyin malaria. When pathogens invade the Yang, yang qi gradually enters the yin division, descending one segment daily; its movement is slow. Thus, attacks occur later each day and are hard to cure. When pathogens invade the Yin, yin qi turns into the yang division, descending two segments daily; its movement is fast. Thus, attacks occur earlier each day and are easy to cure. The treatment method is: if malaria is in the three Yang meridians, treat according to the three Yang meridians; if in the three Yin meridians, treat according to the three Yin meridians. If the wiry pulse transforms into a deficient pulse with sweating, only assist the healthy qi, and the pathogen will eliminate itself. Then, warming and tonifying both yin and yang will surely yield immediate results. The Essentials state: "Malaria involves the three Yang or the three Yin, with distinct symptoms, consistent with the Treatise on Cold Damage." Knowing how to treat cold damage allows one to know how to treat malaria. I say that merely knowing how to treat cold damage is insufficient for treating malaria. One must understand cold damage and know that pathogens lodge in Fengfu to sufficiently treat malaria. What is common with cold damage is the symptoms; what differs is the pulse. The pulse in cold damage changes with yin and yang shifts; the pulse in malaria is characterized by a single "wiry" quality throughout. Understanding how to treat cold damage leads to thorough knowledge of the principles of yin-yang victory and defeat, the timing of pathogen-healthy qi battles, and the pathways of the viscera. Physicians wishing to verify their own cultivation should start by trying to treat malaria.

Tu Weisheng said: Zhou Mengjue's syndrome differentiation and treatment of malaria are indeed exquisite and complete. However, examining his sources, they are mostly derived from Zhang Zhongjing. It is simply that Zhang Zhongjing was concise and comprehensive, while Zhou Mengjue was detailed and elaborate. In essence, by following Zhang Zhongjing's methods, there is no malaria that cannot be cured, nor any case that cannot recover. Generally, malaria is caused by wind-cold entering from the external oil membranes into the internal oil membranes. Zhang Zhongjing's treatment of malaria is based on the Shaoyang meridian, ensuring that pathogens entering from the exterior exit via the exterior. Modern practitioners, unaware of this principle, often focus on abruptly stopping symptoms, leading to recurrence because the root cause is not resolved. Whenever I use Zhang Zhongjing's methods to treat malaria, if one or two doses do not fully cure it, I advise the patient to take several more doses until recovery is complete and sustained. I have excerpted the original text here as a reference for those treating malaria, preserving ancient methods.
Zhang Zhongjing said: The pulse in malaria is naturally wiry. Wiry and rapid indicates much heat; wiry and slow indicates much cold; wiry, small, and tight suggests purgation is better. Wiry and slow can be treated with warming; wiry and tight can be treated with sweating or acupuncture; floating and large can be treated with emesis; wiry and rapid indicates wind-heat, which should be managed through dietary adjustments.
Tang Rongchuan said: The Neijing states that malaria pathogens hide in Fengfu and connect to the Mu Yuan (Membrane Source). Mu means membrane; the source of membranes is below the navel, which is the connecting network of the San Jiao (Triple Burner). Both San Jiao and Bladder are the residences of the Kidney. San Jiao is the Yang residence, transforming water that flows internally to become urine; Bladder is the Yin residence, transforming qi externally to become Wei Qi (Defensive Qi). The Neijing attributes malaria to Wei Qi issues, hence the pathogen is in the Taiyang meridian's Fengfu point. Zhang Zhongjing's commentary focuses on the San Jiao Membrane Source. Therefore, in malaria symptoms, clear urination is absent due to San Jiao dysfunction. Zhang Zhongjing's theory based on Shaoyang aligns with the Neijing. Later generations ignored the San Jiao, mistakenly claiming Zhang Zhongjing contradicted the Neijing.
Zhang Zhongjing said: If malaria starts on the first day of the lunar month, it should heal in fifteen days. If not healed, it should resolve by the end of the month. If still not healed, what then? Answer: This forms a mass called "Malaria Mother" (Nuo Mu). It requires urgent treatment with Biejia Jian Wan (Softshell Turtle Pill).
Biejia Jian Wan (Softshell Turtle Pill)
Trionycis Carapax et Plastron (Bie Jia, 1 qian, roasted), Belamcandae Rhizoma (She Gan, 1 qian), Scutellariae Radix (Huang Qin, 1 qian), Bupleuri Radix (Chai Hu, 1 qian), Psoraleae Fructus (Shu Fu, 1 qian), Zingiberis Rhizoma (Gan Jiang, 1 qian), Rhei Radix et Rhizoma (Da Huang, 1 qian), Cinnamomi Ramulus (Gui Zhi, 7 fen), Asteris Herba (Shi Wei, 1 qian, de-haired), Magnoliae Officinalis Cortex (Hou Po, 1 qian), Campsis Radix (Zi Wei, 1 qian), Pinelliae Rhizoma (Ban Xia, 7 fen), Ecorii Colla (E Jiao, 1 qian), Paeoniae Radix (Shao Yao, 1 qian), Moutan Cortex (Dan Pi, 1 qian), Echinospermi Semen (Jin Chong, 1 qian), Lepidii Semen (Ting Li, 1 qian), Ginseng Radix (Ren Shen, 1 qian), Dianthi Herba (Qu Mai, 1 qian), Vespa Nidus (Feng Ke, 1 qian), Natrii Nitras (Chi Xiao, 1 qian), Scarabaeus (Qiang Lang, 1 qian, roasted), Persicae Semen (Tao Ren, 2 qian).
Grind the above twenty-three ingredients into powder. Take one dou of ash from the kitchen stove and five sheng of clear wine. Boil until half the wine remains, add the softshell turtle carapace, and boil until it dissolves like glue. Strain the juice, add the other medicines, and decoct to form pills the size of mulberry seeds. Take seven pills on an empty stomach, three times a day. (Note: Qianjin Fang uses twelve pieces of Bie Jia, plus 3 fen of Sargassum and 1 fen of Euphorbia. No Shu Fu or Chi Xiao.)
Tang Rongchuan said: Malaria pathogens lie dormant in Ying Blood (Nutritive Blood). They manifest when Wei Qi meets them. Over time, Ying Blood coagulates to form Malaria Mother. Blocked Wei Qi generates phlegm. Thus, blood is the main component of Malaria Mother, while phlegm, generated by Wei Qi, is secondary. Treatment focuses on resolving blood stasis, assisted by moving phlegm and directing qi downward. Understanding this reveals why Zhang Zhongjing's formula contains many blood-breaking herbs: it treats Ying to unblock Wei.
Tu Weisheng said: Various schools debate the mechanism of initial chills followed by fever and the formation of Malaria Mother, but few provide convincing explanations. I speculate that malaria pathogens lodge on the Shaoyang oil membranes. Qi generated by the Lower Jiao must ascend along these membranes to reach the exterior as defense. Pathogens block this ascent, causing severe initial chills. After prolonged struggle between pathogen and healthy qi, the pathogen weakens and healthy qi strengthens. However, the more constrained the healthy qi, the more violently it erupts, causing intense subsequent fever. If pathogens exit with sweat, malaria may heal. Otherwise, if the patient is robust and generates healthy qi quickly, the conflict is urgent. Variations in daily or alternate-day attacks depend on the patient's constitution and qi generation speed. Ying Blood flow follows Wei Qi. When Wei Qi is blocked, Ying Blood stagnates, forming Malaria Mother. Even if pathogens exit, the blood stasis remains like dormant pathogens, allowing recurrence. Thus, Bie Jia, Jin Chong, Da Huang, and Tao Ren attack blood stasis. Hou Po and Ting Li regulate qi. Chai Hu and Gui Zhi release the exterior, while Ren Shen supports. E Jiao and Bai Shao nourish blood. Other clearing and draining herbs ensure pathogens are eliminated without forming Malaria Mother. I hope this view aligns with sage wisdom and welcomes correction from esteemed physicians.
Zhang Zhongjing said: When Yin qi is isolated and Yang qi alone flares, fever occurs with shortness of breath, vexation, hot hands and feet, and nausea, named Dan Malaria (Febrile Malaria). If there is only heat without cold, the pathogen hides internally in the Heart and externally in the muscle spaces, causing muscle wasting.
Tang Rongchuan said: Yin qi refers to Shaoyin Heart and Kidney. Yin deficiency causes fever, shortness of breath, and mental vexation. Pathogens entering the Heart indicate Shaoyin Yin isolation. Yang qi refers to Taiyang Bladder. Water-derived Yang transforms into heat to defend the body. Unchecked Yang causes pure heat; merging with Yangming causes hot limbs; merging with San Jiao causes vomiting; merging with skin and muscles causes wasting. Treat Shaoyin with Ji Zi Huang Tang (Chicken Egg Yolk Decoction); treat Taiyang with Baihu Tang (White Tiger Decoction). Later formulas like Qingwen Baidu Yin can treat both.
According to Records of the Grand Historian, wind-dan lodges in the Bladder. Dan Malaria also originates in the Bladder, opposite to Mu Malaria (Cold Malaria), which involves the Heart.
Zhang Zhongjing said: Wen Malaria (Warm Malaria) presents with a normal pulse, no chills but fever, painful joints, and occasional vomiting. Baihu Jia Guizhi Tang (White Tiger Plus Cinnamon Twig Decoction) is indicated.

Anemarrhenae Rhizoma (Zhi Mu, 1 qian), Gypsum Fibrosum (Shi Gao, 1 qian), Glycyrrhizae Radix et Rhizoma (Gan Cao, 1 qian), Oryza Sativa (Jing Mi, 1 qian), Cinnamomi Ramulus (Gui Zhi, 7 fen).
Tang Rongchuan said: Fever without chills is the primary indication for Baihu Tang. Gui Zhi is added for painful joints, indicating latent cold in the sinews/joints, which Gui Zhi expels.
Zhang Zhongjing said: Malaria with predominant chills is named Mu Malaria (Cold Malaria), treated with Shuqi San.
