夏日伤暑，秋必病疟。疟之发以时者，此是邪客于风府，循膂而下。卫气一日一夜常大
会于风府，其明日日下一节，故其作也晏。此先客于脊背也，每至于风府则腠理开，腠理开
则邪气入，邪气入则病作，此所以日作常晏也。卫气之行风府，日下一节，二十一日下至尾
，二十二日入脊内，注于伏冲之脉，其气上行九日出于缺盆之中，其气既上，故其病稍早
发。其间日发者，由邪气内薄五脏，横连募原，其道远，其气深，其行迟，不能日作，故间
日蓄积乃作。夫卫气每至于风府，腠理而开，开则邪入焉。其卫气日下一节，其气之发也，
不当风府，其日作者奈何？然风府无常，卫气之所应，必开其腠理，邪气之所舍，则其病已
风之与疟也，相与同类，而风独常在也，而疟特以时休何也？由风气留其处，疟气随经
络沉以内薄，故卫气应乃作。阳当陷而不陷，阴当升而不升，为邪所中，阳遇邪则卷，阴遇
邪则紧，卷则恶寒，紧则为栗，寒栗相搏，故名疟。弱乃发热，浮乃汗出，旦中旦发，暮中
暮发。夫疟，其人形瘦，皮必栗。
病疟，以月一日发，当以十五日愈。设不愈，月尽解。

凡疟先发如食倾，乃可以治之，过之则失时。
夏季感受暑邪，到了秋季就会发生疟疾。疟疾发作时间有定时的，这是因为邪气客居于风府穴，沿着脊柱向下行。卫气在一天一夜中常在风府穴大会合，第二天卫气下行一节脊椎，所以疟疾的发作时间就越来越晚。这是因为邪气先客居在脊背，每当卫气运行到风府穴时，腠理（皮肤毛孔）就会开泄，腠理开泄则邪气乘虚而入，邪气入内则疾病发作，这就是为什么每天发作的时间都逐渐推迟的原因。
卫气运行经过风府，每天下行一节，二十一天后下行至尾骶部，第二十二天进入脊柱内部，注入伏冲脉（深层经脉），其气向上运行九天，出于缺盆穴（锁骨上窝）之中，因为气已经上行，所以发病时间逐渐提前。
如果疟疾是隔日发作的，是因为邪气内迫五脏，横向连及募原（脏腑间的膜原），路径遥远，邪气深藏，运行迟缓，不能每日发作，所以隔日蓄积力量后才发作。每当卫气运行到风府穴，腠理开泄，开泄则邪气侵入。卫气每天下行一节，邪气发作时并不一定正对风府穴，那为什么有的疟疾每天发作呢？然而风府穴的位置并非固定不变，卫气所应之处，必然导致腠理开泄，邪气所停留的地方，病就会发作。风邪与疟邪同类，但风邪常常存在，而疟邪却定时休止，为什么呢？因为风邪留滞于体表，而疟邪随经络深入体内，所以只有当卫气运行与之相会时才发作。阳气应当下降而不降，阴气应当上升而不升，被邪气所中，阳气遇邪则收缩，阴气遇邪则紧缩，收缩则恶寒，紧缩则战栗，寒战相互搏结，所以称为疟疾。虚弱则发热，浮越则汗出，早晨受邪早晨发作，傍晚受邪傍晚发作。患疟疾的人，形体消瘦，皮肤必定战栗。
患疟疾，如果在农历初一发病，应当在十五天痊愈；如果不好转，到月底也会解除。
足太阳经疟疾，使人腰痛头重，寒气从背部升起，先恶寒后发热，口渴，渴止后出汗，难以治愈，应刺委中穴出血。
足少阳经疟疾，使人身体懈怠疲倦，恶寒不严重，发热也不严重，厌恶见人，见到人内心恐惧不安，发热多且出汗严重，应刺足少阳经穴位。
足阳明经疟疾，使人先恶寒，瑟瑟发抖，寒冷持续很久才发热，热退后出汗，喜欢见到阳光或火气，感到舒适，应刺足阳明经脚背上的穴位。
足太阴经疟疾，使人心情不悦，喜欢叹气，食欲不振，多有寒热出汗，病发时容易呕吐，吐完后病情减轻，应立即取穴治疗。
足少阴经疟疾，使人呕吐严重，寒热持续时间久，发热多而恶寒少，想关闭门窗独处，病情难以停止。
足厥阴经疟疾，使人腰痛，小腹胀满，小便不利，像癃闭（排尿困难）的样子但不是真正的癃闭，频繁想小便，心中恐惧，气不足，肠中郁闷不适，应刺足厥阴经穴位。
肺疟，使人心中寒冷，寒冷严重时发热，容易惊恐，好像看到了什么幻象，应刺手太阴肺经、手阳明大肠经穴位。
心疟，使人心中烦闷严重，想要喝冷水，且寒冷多而发热不严重，或者发热严重，应刺手少阴心经穴位。
肝疟，使人面色青苍，喜欢叹气，状态好像死人一样，应刺足厥阴肝经见血。
脾疟，使人迅速感到寒冷，腹中疼痛，发热时肠中鸣响，鸣响后出汗，应刺足太阴脾经穴位。
肾疟，使人洒洒然畏寒，腰脊疼痛且转动困难，大便困难，头晕目眩，手足寒冷，应刺足太阳膀胱经、足少阴肾经穴位。
胃疟，使人即将发病时，容易饥饿但不能进食，吃了东西后感觉支撑胀满，腹部膨大，应刺足阳明胃经、足太阴脾经横行的血脉出血。
肺脏患病引发的疟疾，症状忽来忽去，使人心中寒冷，寒冷严重时发热，容易惊恐，好像看到了什么，这是肺疟的症状。如果一个人原本说话声音洪亮，突然变得恍惚不清，拖长气息用力才能说出话，反而不同于常人，呼唤他共同说话，他直视却不回应，虽然说是没病，但形势表明寿命不会长久。这就是肺病的声音征候。观察病症，表里相应，根据病因审察治疗，才不会失误。
心脏患病引发的疟疾，使人心中烦乱，病欲饮清水多，寒少热甚。如果一个人本来性情温和文雅，突然反常，或者话没说完就停下，用手剔脚趾甲，这久必死，灾祸虽未降临，但被称为“行尸”。这是心病的声音征候，虚证则补益，实证则泻除，不可治者，明察之。
肝脏患病引发的疟疾，使人面色青苍，气息喘闷，颤抖动摇，状态像死人一样。如果一个人本来很少悲伤愤怒，忽然嗔怒，言语反常，时而宽松时而急促，话没说完，手向眼睛方向动作，好像在思考什么，如果不立即生病，灾祸必将到来。这是肝病的声音征候，此人如果是虚证，则为寒风所伤；如果是实证，则为热气所损。阳证则泻之，阴证则补之。
脾脏患病引发的疟疾，使人寒冷时腹中痛，发热时肠中鸣响，鸣响后出汗。如果这个人本来很少喜怒，忽然反常，喜欢无节制地笑，对着空气傻笑，不回答别人，这是脾病的声音征候。不超过十天半月，灾祸必至。
肾脏患病引发的疟疾，使人凄凄然畏寒，腰脊疼痛且转动困难，大便涩滞，身体抖动不定，手足寒冷。如果一个人本来不喜欢也不愤怒，忽然口吃且好怒，反于常性，这是肾已受伤，虽然尚未发觉，但这是征兆。看见人还没说话就先开口笑，然后闭口无声，举手遮挡极腹部，这是肾病的声音征候。虚实表里，浮沉清浊，应当以此察之，据此治之。
疟疾的脉象自然呈弦脉，弦数脉多热，弦迟脉多寒。弦小紧脉，可用下法；弦迟脉，用温药治愈；脉数而紧，可发汗，适宜针灸；脉浮大，不可针灸，可用吐法。
凡是疟疾刚发作，大约一顿饭的时间，才可以治疗，过了这个时机就失去了最佳治疗时间。
Summer injury by heat (Shu) leads to malaria in autumn. Malaria with fixed timing of onset is due to pathogenic factors lodging at Fengfu (GV16), descending along the Du Meridian. Wei Qi (Defensive Qi) gathers at Fengfu once a day and night; the next day it descends one vertebral segment, hence the delayed onset. This indicates pathogens initially lodged in the back. When Wei Qi reaches Fengfu, the interstices (Cou Li) open; upon opening, pathogens enter, causing disease manifestation, explaining the daily delay in onset.
Wei Qi moves down one segment daily via Fengfu, reaching the coccyx on the 21st day, entering the spine interior on the 22nd, and pouring into the Fu Chong Mai (Deep Thoroughfare Vessel). Its qi ascends for nine days, emerging from Quepen (ST12). Since the qi has ascended, the onset becomes earlier.
Intermittent malaria occurs because pathogens press inward against the Zang organs and connect horizontally to the Mu Yuan (Diao Membrane). The path is long, the qi deep, and movement slow, preventing daily attacks; thus, it accumulates power over two days before manifesting. Whenever Wei Qi reaches Fengfu, interstices open, allowing pathogen entry. Although Wei Qi descends daily, onset does not always align with Fengfu. Why do some cases occur daily? Fengfu is not fixed; where Wei Qi responds, interstices open, and where pathogens lodge, disease arises. Wind pathogens and malaria pathogens are similar, yet wind persists while malaria pauses. This is because wind remains superficial, whereas malaria pathogens sink deeply along meridians, acting only when Wei Qi arrives. Yang should descend but fails; Yin should ascend but fails. Struck by pathogens, Yang contracts causing aversion to cold, Yin tightens causing shivering. Cold and shivering contend, named "Malaria." Weakness leads to fever, floating leads to sweating; morning strike causes morning onset, evening strike causes evening onset. Malaria patients are emaciated with shivering skin.
If malaria begins on the first day of the lunar month, it should heal by the 15th. If not, it resolves by month's end.
Taiyang Malaria causes lower back pain, heavy head, cold rising from the back, initial chills followed by fever, thirst, and sweating after thirst ceases. It is difficult to cure; bleed Weizhong (BL40). Shaoyang Malaria causes body fatigue, mild chills and fever, aversion to people, inner fear, abundant heat and sweat. Puncture Shaoyang points. Yangming Malaria causes initial chills, trembling, prolonged cold before fever, sweating after heat subsides. Relief comes from sunlight or fire. Puncture Yangming points on the dorsum of the foot. Taiyin Malaria causes depression, frequent sighing, anorexia, frequent chills/fever/sweating. Nausea occurs at onset, subsiding afterward. Treat immediately. Shaoyin Malaria causes severe vomiting, prolonged chills/fever, more heat than cold, desire to stay indoors alone. Hard to stop. Jueyin Malaria causes lower back pain, abdominal fullness, dysuria resembling Gong (strangury) but not true Gong, frequent urination, fear, Qi deficiency, intestinal oppression. Puncture Jueyin points.
Lung Malaria causes heart cold, severe chills with intermittent fever, fright, visual hallucinations. Puncture Hand Taiyin and Hand Yangming points. Heart Malaria causes severe mental restlessness, desire for cold water, more cold than heat, or severe heat. Puncture Hand Shaoyin points. Liver Malaria causes pale/greenish complexion, sighing, appearance like death. Bleed Jueyin points. Spleen Malaria causes rapid chills, abdominal pain, bowel sounds during heat, sweating after sounds cease. Puncture Taiyin points. Kidney Malaria causes shivering, painful stiff lower back, difficulty defecating, dizziness, cold extremities. Puncture Foot Taiyang and Foot Shaoyin points. Stomach Malaria causes hunger without ability to eat, postprandial distension and abdominal enlargement. Bleed transverse vessels of Foot Yangming and Taiyin.
Malaria caused by Lung disease features fluctuating symptoms, heart cold, severe chills with fever, fright, hallucinations. If a person with normally loud voice suddenly speaks faintly, dragging breath, and ignores calls despite appearing healthy, life is short. This is the vocal sign of Lung disease. Observe exterior-interior correspondence, treat according to origin.
Malaria caused by Heart disease features mental distress, desire for cold water, less cold, severe heat. If a gentle person suddenly acts erratically, stops mid-sentence, picks toenails, they will likely die soon ("Walking Corpse"). Deficiency requires tonification, excess requires purging. Incurable cases must be clearly identified.
Malaria caused by Liver disease features greenish complexion, panting, tremors, death-like state. If a calm person suddenly becomes angry, speaks abnormally, gestures toward eyes, disaster looms. Deficiency from cold wind requires tonifying Yin; Excess from heat requires draining Yang.
Malaria caused by Spleen disease features abdominal pain in cold, bowel sounds and sweating in heat. If a balanced person suddenly laughs excessively at nothing, ignoring others, disaster comes within ten days. This is the vocal sign of Spleen disease.
Malaria caused by Kidney disease features shivering, painful stiff back, constipation, tremors, cold limbs. If a calm person suddenly stammers and gets angry, or smiles before speaking then closes mouth silently while guarding abdomen, Kidney is injured. Assess emptiness/fullness, exterior-interior, floating/sinking, clear/turbid to treat.
Malaria pulse is naturally Wiry (Xian). Wiry-rapid indicates heat; Wiry-slow indicates cold. Wiry-small-tight allows purgation; Wiry-slow responds to warming herbs. Rapid-tight allows diaphoresis and acupuncture. Floating-large prohibits acupuncture; induces vomiting instead.
Treat malaria within the time of one meal after onset; otherwise, the opportunity is lost.
