风癫者，由血气虚，邪入于阴经故也。人有血气少，则心虚而精神离散，魂魄妄行，因
为风邪所伤，故邪入于阴，则为癫疾。又人在胎，其母卒大惊，精气并居，令子发癫。其发
则仆地，吐涎沫，无所觉是也。原其癫病，皆由风邪故也。其汤熨针石，别有正方，补养宣
导，今附于后。
《养生方》云∶夫人见十步直墙，勿顺墙而卧，风利吹人，必发癫痫及体重。人卧春夏
向东，秋冬向西，此是常法。
《养生方·导引法》云∶还向反望，不息七通。治咳逆、胸中病、寒热癫疾、喉不利、
咽干咽寒。
又云∶以两手承辘轳倒悬，令脚反在上元。愈头眩风癫。坐地，舒两脚，以绳绊
之，以大绳绊讫，拖辘轳上来下去，以两手挽绳，使脚上头下，使离地，自极十二通。
愈头眩风癫。久行，身卧空中，而不坠落。
五癫者，一曰阳癫，发如死人，遗尿，食顷乃解；二曰阴癫，初生小时，脐疮未愈，数
洗浴，因此得之；三曰风癫，发时眼目相引，牵纵反强，羊鸣，食顷方解。由热作汗出当风
，因房室过度，醉饮，令心意逼迫，短气脉悸得之；四曰湿癫，眉头痛，身重。坐热沐头，
湿结，脑沸未止得之；五曰马癫，发作时时，反目口噤，手足相引，身体皆热。
诊其脉，心脉微涩，并脾脉紧而疾者，为癫脉也。肾脉急甚，为骨癫疾。脉洪大而长者
，癫疾；脉浮大附阴者，癫疾；脉来牢者，癫疾。三部脉紧急者可治；发则仆地，吐沫无知
，若强 ，起如狂，及遗粪者，难治。脉虚则可治，实则死。脉紧弦实牢者生，脉沉细
小者死。脉搏大滑，久久自已。其脉沉小急疾，不治；小牢急，亦不可治。
风癫，是由于血气虚弱，邪气侵入阴经所致。人体如果血气不足，就会导致心虚，进而使精神离散、魂魄妄动，此时若再受到风邪伤害，邪气就会侵入阴经，从而形成癫疾。另外，胎儿在母体内时，如果母亲突然遭受大惊，精气相互搏结，也会导致孩子出生后发生癫病。其发作时表现为倒地、口吐涎沫、意识丧失。推究这种癫病的根源，都是由风邪引起的。关于治疗此病的汤药、热敷、针刺和砭石疗法，另有专门的方剂，补益调养及导引宣通的方法，现附在后面。
《养生方》说：人在行走时，看到十步之内有笔直的墙壁，不要顺着墙壁躺卧，因为风容易吹袭人体，必然会导致癫痫发作以及身体沉重。人睡觉时，春夏季节头朝东，秋冬季节头朝西，这是常规的方法。
《养生方·导引法》说：向后转头反视，保持呼吸通畅七次。可以治疗咳嗽气逆、胸中疾病、寒热交替的癫疾、咽喉不利、咽干咽冷。
又说：用双手握住辘轳柄倒挂身体，让脚反过来位于上方。可以治愈头晕目眩和风癫。坐在地上，伸直双腿，用绳子绊住脚，绑好大绳后，拉动辘轳上下运动，用双手拉紧绳子，使脚在上头在下，双脚离地，尽力做十二次。可以治愈头晕目眩和风癫。长期练习，甚至能身体悬空而不坠落。
五癫，第一种叫阳癫，发作时像死人一样，伴有遗尿，过了一顿饭的时间才缓解；第二种叫阴癫，多在婴儿出生不久，脐带伤口未愈合时，多次洗浴而感染得之；第三种叫风癫，发作时两眼互相牵引，肢体牵拉强直或反转，发出羊叫声，过了一顿饭的时间才缓解。这是由于发热出汗时当风受邪，或因房事过度、醉酒饮酒，导致心意紧迫、气短脉悸而得病；第四种叫湿癫，症状为眉骨头痛、身体沉重。是因为坐热后洗头，湿气凝结，脑部热气未止而得病；第五种叫马癫，发作时两目上翻、牙关紧闭，手足互相牵引，全身发热。
诊察患者的脉象，如果心脉微涩，或者脾脉紧而快，属于癫病的脉象。肾脉急甚，是骨癫疾。脉象洪大而长的，是癫疾；脉象浮大且按之及阴的，是癫疾；脉来坚牢的，是癫疾。三部脉象紧急的可以治愈；发作时倒地、吐沫无知、僵硬如狂，以及大小便失禁的，难治。脉虚的可以治愈，脉实的预后不良（死）。脉紧弦实牢的预后良好（生），脉沉细小的预后不良（死）。脉搏大滑的，时间久了会自行痊愈。脉象沉小急疾的，无法治愈；脉小牢急的，也无法治愈。
Wind Dian (Feng Dian, wind-induced epilepsy), arises from deficiency of blood and qi, allowing pathogenic factors to invade the Yin meridians. When a person has insufficient blood and qi, the Heart becomes deficient, leading to the dispersion of spirit and the erratic movement of hun and po souls. If subsequently injured by wind pathogens, the evil enters the Yin meridians, resulting in Dian disease. Furthermore, if the mother suffers sudden fright while the fetus is in utero, the essence and qi may congregate abnormally, causing the child to develop Dian after birth. During an attack, the patient falls to the ground, foams at the mouth, and loses consciousness. The root cause of Dian disease is attributed to wind pathogens. Decoctions, hot compresses, acupuncture, and stone therapy have separate specific formulas; methods for tonification, nourishment, and guiding/dispersing are attached hereafter.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) states: When walking, if one sees a straight wall within ten paces, one should not lie down parallel to the wall. Wind blows easily upon the body, inevitably triggering epilepsy and heaviness of the body. When sleeping, facing east in spring and summer, and west in autumn and winter, is the standard practice.
The *Yangsheng Fang · Daoyin Fa* (Guiding and Pulling Method) states: Turn the head backward to look behind, maintaining normal breathing for seven cycles. This treats cough with reversed qi, chest diseases, alternating chills and fever with Dian, throat obstruction, dryness, and coldness of the throat.
It also states: Hold the handle of a windlass with both hands and hang upside down, so that the feet are positioned above the head. This cures dizziness and wind Dian. Sit on the ground, extend both legs, and bind them with a rope. After securing the large rope, pull the windlass up and down, holding the rope with both hands so that the feet are above and the head below, lifting the feet off the ground. Perform this maximally for twelve cycles. This cures dizziness and wind Dian. With long-term practice, one may even suspend in mid-air without falling.
The Five Dians are as follows: First is Yang Dian, where during an attack the patient appears like a corpse, experiences urinary incontinence, and recovers after about the time it takes to eat a meal. Second is Yin Dian, which often occurs in infants shortly after birth when the umbilical wound has not yet healed, due to frequent bathing. Third is Wind Dian, characterized during attacks by eyes pulling toward each other, limb traction, rigidity or reversal, bleating like a sheep, and recovery after about the time it takes to eat a meal. It is caused by sweating due to heat and exposure to wind, excessive sexual intercourse, drunken drinking, leading to mental urgency, shortness of breath, and palpitations. Fourth is Shi Dian (Damp Dian), presenting with pain in the eyebrow region and heaviness of the body. It results from washing the head while hot after sitting, causing dampness to condense while brain heat persists. Fifth is Ma Dian (Horse Dian), where during attacks the eyes roll back, the jaw is clenched, limbs are pulled together, and the whole body feels hot.
Diagnosing the pulse: A faint and choppy Heart pulse, or a tight and rapid Spleen pulse, indicates Dian. An extremely urgent Kidney pulse indicates Bone Dian. A surging, large, and long pulse indicates Dian; a floating, large pulse that extends to the Yin level indicates Dian; a firm and solid pulse indicates Dian. Urgent pulses in all three positions are treatable. Attacks involving falling to the ground, foaming at the mouth with loss of consciousness, stiffness resembling mania, and fecal incontinence are difficult to treat. A deficient pulse is treatable; an excess pulse indicates death. A tight, wiry, excess, and solid pulse indicates survival; a deep, fine, and small pulse indicates death. A large and slippery pulse will resolve spontaneously over time. A deep, small, urgent, and rapid pulse is untreatable; a small, firm, and urgent pulse is also untreatable.
