将适失宜，脾胃虚弱者，石势结滞，乘于脾胃，致令脾胃气不和，不胜于谷，故气逆而
呕。调之即愈。
将适失宜，饮食乖度，鬲内生痰热，痰热之气熏肝，肝候目，故目无所见而疼痛。
本患风劳，而服散石，风劳未尽，石势因发，解石之后，体尚虚羸，故犹挟风劳也。
服散而积饮酒，石因酒势而盛，敷散经络，故烦而发热也。
经言∶春气温和，夏气暑热，秋气清凉，冬气冰寒，此则四时正气之序也。冬时严寒，
万类深藏，君子固密，则不伤于寒。夫触冒之者，乃为伤寒耳。其伤于四时之气，皆能为病
，而以伤寒为毒者，以其最为杀厉之气也。即病者，为伤寒；不即病者，其寒毒藏于肌骨中
；至春变为温病；夏变为暑病。暑病者，热重于温也。是以辛苦之人，春夏必有温病者，皆
由其冬时触冒之所致，非时行之气也。其时行者，是春时应暖而反寒，夏时应热而反冷，秋
时应凉而反热，冬时应寒而反温，非其时而有其气。是以一岁之中，病无少长，多相似者，
此则时行之气也。
夫伤寒病者，起自风寒，入于腠理，与精气交争，荣卫痞隔，周行不通。病一日至二日
，气在孔窍皮肤之间，故病者头痛恶寒，腰背强重，此邪气在表，洗浴发汗即愈。病三日以
上，气浮在上部，胸心填塞，故头痛、胸中满闷，当吐之则愈。病五日以上，气深结在脏，
故腹胀身重，骨节烦疼，当下之则愈。
夫热病者，皆伤寒之类也。或愈或死，其死皆以六七日间，其愈皆以十日以上，何也？
巨阳者，诸阳之属也，其脉连于风府，故为诸阳主气。人之伤于寒也，则为病热，热虽甚不
死；其两感于寒而病者，必死。两感于寒者，其脉应与其病形何如？两伤于寒者，病一日，
则巨阳与少阴俱病，则头痛、口干烦满。二日，则阳明与太阴俱病，则腹满、身热、不食、
谵言。三日，则少阳与厥阴俱病，则耳聋、囊缩、厥逆，水浆不入，则不知人，六日而死。
夫五脏已伤，六腑不通，荣卫不行，如是之后，三日乃死何也？阳明者，十二经脉之长也。
其气血盛，故不知人，三日其气乃尽，故死。
其不两伤于寒者，一日巨阳受之，故头项痛，腰脊强。二日阳明受之，阳明主肉，其脉
夹鼻络于目，故身热而鼻干，不得卧也。三日少阳受之，少阳主骨，其脉循胁络于耳，故胸
胁痛耳聋。三阳经络皆受病，而未入通于脏也，故可汗而已。四日太阴受之，太阴脉布于胃
，络于嗌，故腹满而嗌干。五日少阴受之，少阴脉贯肾络肺，系舌本，故口热舌干而渴。六
日厥阴受之，厥阴脉循阴器而络于肝，故烦满而囊缩。三阴三阳，五脏六腑皆病，荣卫不行
，五脏不通则死矣。其不两感于寒者，七日巨阳病衰，头痛少愈。八日阳明病衰，身热少愈
。九日少阳病衰，耳聋微闻。十日太阴病衰，腹减如故，则思饮食。十一日少阴病衰，渴止
不满，舌干已而咳。十二日厥阴病衰，囊从少腹微下。大气皆去，病日已矣。
治之奈何？治之各通其脏脉，病日衰。其病未满三日者，可汗而已，其病三日过者，可
泄之而已。太阳病，头痛至七日以上，并自当愈，其经竟故也。若欲作再经者，当针补阳明
，使经不传则愈矣。
相病之法，视色听声，观病之所。候脉要诀，岂不微乎。脉洪大者，有热，此伤寒病也
。夫伤寒脉洪浮，秋佳春成病。寸口脉紧者，伤寒头痛。脉来洪大，伤寒病。少阴病，恶寒
身拳而利，手足四逆者，不治；其人吐利，躁逆者死。利止而眩，时时自冒者死。四逆，恶
寒而身拳，其脉不至，其人不烦而躁者死。病六日，其息高者死。伤寒热盛，脉浮大者生，
沉小者死。头痛，脉短涩者死；浮滑者生。未得汗，脉盛大者生；细小者死。诊人
大热，其脉细小者，死不治。伤寒热病，脉盛躁不得汗者，此阳之极，十死不治。未得
汗，脉躁疾，得汗生；不得汗难瘥。头痛脉反涩，此为逆，不治；脉浮大而易治；细微为难
治。
发汗若吐下者、若亡血无津液者，而阴阳自和必愈。夫下后发汗，其人小便不利，此亡
津液，勿治，其小便利，必自愈。阳已虚，尺中弱者，不可发其汗也。咽干者，不可发其汗
也。伤寒病，脉弦细，头痛而发热，此为属少阳。少阳不可发汗，发汗则 语，为属胃
。胃和则愈，不和则烦而悸。少阴病，脉细沉而微，病在里，不可发其汗。少阴病，脉微，
亦不可发汗，无阳故也。阳已虚，尺中弱涩者，复不可下。太阳病，发热而恶寒，热多而寒
少，脉微弱，则无阳，不可发其汗；脉浮，可发其汗。发热自汗出而不恶寒，关上脉细数，
不可吐。若诸四逆厥者，不可吐，虚家亦然。寒多热少，可吐者，此谓痰多也。治疟亦如
之。头项不强痛，其寸脉微浮，胸中 牢，气上冲喉咽不得息，可吐之。治伤寒欲下之
，切其脉牢，牢实之脉，或不能悉解，宜摸视手掌， 汗湿者，便可下矣。若掌
不汗，病虽宜下，且当消息，温暖身体，都皆津液通，掌亦自汗，下之即了矣。太阴之为病
，腹满吐食，不可下，下之益甚，时腹自痛。下之，胸下结牢，脉浮，可发其汗。阳明病，
心下牢满，不可下，下之遂利，杀人，不可不审，不可脱尔，祸福正在于此。
太阳与少阳并病，心下牢，头项强眩，不可下。三阳合病，腹满身重，大小便调，其脉
浮牢而数，渴欲饮水，此不可下。其汤熨针石，别有正方，补养宣导，今附于后。
《养生方·导引法》云∶端坐生腰，徐徐以鼻纳气，以右手持鼻，徐徐闭目吐气。治伤
寒头痛洗洗，皆当以汗出为度。
又云∶举左手，顿左足，仰掌，鼻纳气四十息止，除身热背痛。
如果起居调摄不当，脾胃虚弱的人，石药（矿物类药物）的势气结滞，侵犯脾胃，导致脾胃之气不和，不能运化食物，所以气机上逆而呕吐。调理得当即可痊愈。
如果起居调摄不当，饮食失去节制，膈间内生痰热，痰热之气熏蒸肝脏，肝开窍于目，所以眼睛看不见东西并且疼痛。
居住处所触犯温热之气，导致石药的势气不能宣散，内壅脏腑，与人体正气相搏结，所以心腹胀满。
原本患有风劳病，又服用发散石药的风劳未尽，石药的势气因而发作，在解除了石毒之后，身体仍然虚弱消瘦，所以仍然夹杂风劳病邪。
服用发散石药后又大量饮酒，石药因酒力而势盛，敷散于经络之中，所以心烦而且发热。
经书上说：春天气候温和，夏天气候暑热，秋天气候清凉，冬天气候冰寒，这是四时正气的正常次序。冬天严寒，万物深藏，君子固密腠理，就不会受寒邪伤害。那些触犯冒犯寒邪的人，才会得伤寒病。凡是受到四时不正之气的侵袭，都能致病，但其中以伤寒为最毒，因为它是杀伤力最强的邪气。感邪后立即发病的，称为伤寒；没有立即发病的，其寒毒潜伏在肌骨之中；到了春天变为温病；到了夏天变为暑病。暑病比温病的热势更重。因此，辛勤劳作的人，在春夏季节必定会有温病发生，这都是因为冬天时触犯寒邪所致，并非时行之气。所谓时行之气，是指春天应当温暖却反而寒冷，夏天应当炎热却反而寒冷，秋天应当凉爽却反而炎热，冬天应当寒冷却反而温暖，即非其时而有其气。因此在一岁之中，病人无论老少，病情大多相似，这就是时行之气。
所谓伤寒病，起自风寒，侵入腠理，与人体精气交争，导致营卫痞塞阻隔，周身气血运行不通。患病一到两天，邪气在孔窍皮肤之间，所以病人头痛、恶寒、腰背强直沉重，这是邪气在表，洗浴发汗即可痊愈。患病三天以上，邪气浮越在上部，胸心填塞，所以头痛、胸中满闷，应当用吐法治疗即可痊愈。患病五天以上，邪气深结在脏，所以腹胀、身重、骨节烦痛，应当用下法治疗即可痊愈。
所谓热病，都属于伤寒的范畴。有的痊愈，有的死亡，死亡的都在六七天之间，痊愈的都在十天以上，为什么呢？巨阳经（太阳经）是诸阳经的统领，它的脉连于风府穴，所以作为诸阳主气。人感受寒邪，就会得热病，热势虽然严重也不会死；如果是两感于寒（表里两经同时受邪）而发病的，必定死亡。两感于寒的病人，其脉象和病症表现是怎样的呢？两伤于寒，第一天，则巨阳经与少阴经同时发病，出现头痛、口干、心烦胀满。第二天，则阳明经与太阴经同时发病，出现腹满、身热、不能进食、胡言乱语。第三天，则少阳经与厥阴经同时发病，出现耳聋、阴囊收缩、四肢厥冷，水浆不进，神志昏迷，第六天死亡。五脏已经受伤，六腑不通，营卫不行，在此之后三天才死亡，为什么呢？阳明经是十二经脉之长，其气血旺盛，所以神志昏迷，经过三天其气耗尽，所以死亡。
那些不是两感于寒的，第一天巨阳经受邪，所以头项痛、腰脊强直。第二天阳明经受邪，阳明经主肌肉，其脉夹鼻络于目，所以身热、鼻干、不能安卧。第三天少阳经受邪，少阳经主骨，其脉循胁络于耳，所以胸胁痛、耳聋。三阳经络都受病，但未传入内脏，所以可以通过发汗治愈。第四天太阴经受邪，太阴脉布于胃，络于咽喉，所以腹满、咽喉干燥。第五天少阴经受邪，少阴脉贯肾络肺，系舌本，所以口热、舌干而渴。第六天厥阴经受邪，厥阴脉循阴器络于肝，所以心烦胀满、阴囊收缩。三阴三阳、五脏六腑都病了，营卫不行，五脏不通就会死亡。那些不是两感于寒的，第七天巨阳经病势衰退，头痛稍好。第八天阳明经病势衰退，身热稍退。第九天少阳经病势衰退，耳聋稍微能听见声音。第十天太阴经病势衰退，腹部减除如常，开始想吃饭。第十一天少阴经病势衰退，口渴停止，不再胀满，舌干已缓解并开始咳嗽。第十二天厥阴经病势衰退，阴囊从少腹微微下垂。大气邪气都已去除，病一天天好了。
如何治疗呢？治疗应分别疏通各脏的经脉，病势一天天衰退。病未满三天的，可以通过发汗治愈；病超过三天的，可以通过泄下治愈。太阳病，头痛持续七天以上，本来就会自愈，因为该经的气血运行周期已结束。如果想要防止病传变到下一经，应当针刺补益阳明经，使经脉不传变就能痊愈。
诊断疾病的方法，是观察面色、听声音、查看病变部位。诊察脉象的要诀，难道不微妙吗？脉象洪大的，有热，这是伤寒病。伤寒脉象洪浮，秋季适宜（指脉证相符），春季容易成病。寸口脉紧的，是伤寒头痛。脉来洪大的，是伤寒病。少阴病，恶寒、身体蜷缩且腹泻，手足四肢厥冷的，属不治之症；其人上吐下泻、烦躁逆乱的，死亡。腹泻停止但头晕，时常自觉昏蒙的，死亡。四肢厥冷，恶寒且身体蜷缩，脉象摸不到的，人不烦躁但躁动的，死亡。患病六天，呼吸高促的，死亡。伤寒热盛，脉象浮大的生，沉小的死。头痛，脉短涩的死；浮滑的生。未得汗，脉盛大的生；细小的死。诊察人大热，脉细小的，死，不可治。伤寒热病，脉盛躁且不得汗的，这是阳气极盛，十死无救。未得汗，脉躁疾的难治，得汗的能生；不得汗的难以痊愈。头痛脉反涩的，此为逆证，不可治；脉浮大的易治；细微的难治。
经过发汗或吐下，或者亡血无津液的，只要阴阳自和必愈。如果在攻下后又发汗，病人小便不利，这是亡失津液，不要治疗，如果小便利，必定自愈。阳气已虚，尺中脉弱的，不可发汗。咽干的，不可发汗。伤寒病，脉弦细，头痛且发热，这属于少阳病。少阳病不可发汗，发汗则谵语，这属于胃家实。胃气和则愈，不和则心烦心悸。少阴病，脉细沉而微，病在里，不可发汗。少阴病，脉微，也不可发汗，因为没有阳气。阳气已虚，尺中脉弱涩的，也不可用下法。太阳病，发热而恶寒，热多寒少，脉微弱，这是无阳，不可发汗；脉浮的，可发汗。发热自汗出且不恶寒，关上脉细数，不可用吐法。如果是各种四肢厥逆者，不可用吐法，体虚之人也是如此。寒多热少的，可用吐法，这是因为痰多。治疗疟疾也如此。头项不强痛，寸脉微浮，胸中有物阻塞，气上冲喉咽不得呼吸，可用吐法。治疗伤寒想要用下法的，切其脉牢，牢实之脉，或者不能全部理解，宜触摸手掌，手掌出汗湿的，就可以用下法了。如果手掌不出汗，病虽宜下，暂且斟酌，温暖身体，等到津液通畅，手掌自然出汗，再用下法即可解决。太阴病，表现为腹满、吐食，不可用下法，用下法则病情加重，时常腹痛。如果用下法，胸下结块坚硬，脉浮的，可发汗。阳明病，心下硬满，不可用下法，用下法则导致腹泻，杀人，不可不审慎，不可轻率，祸福正在于此。
太阳与少阳并病，心下硬满，头项强痛眩晕，不可用下法。三阳合病，腹满身重，大小便正常，脉浮牢而数，口渴想喝水，这不可用下法。汤熨、针石等其他方剂，以及补养、宣导等方法，现在附在后面。
《养生方·导引法》说：端正坐好，腰部挺直，慢慢地用鼻子吸气，用右手捏住鼻子，慢慢地闭目呼气。治疗伤寒引起的头痛凛凛恶寒，都以出汗为限度。
If daily life is not regulated properly, in individuals with weak Spleen and Stomach (Spleen and Stomach deficiency), the momentum of mineral drugs (Shi Shi) becomes stagnant and attacks the Spleen and Stomach, causing disharmony of their Qi. Consequently, they cannot tolerate food, leading to rebellious Qi and vomiting. With proper regulation, recovery occurs.
If daily life is not regulated properly and dietary habits are excessive, phlegm-heat generates in the diaphragm. The Qi of phlegm-heat steams the Liver. Since the Liver opens into the eyes, vision is lost accompanied by pain.
Exposure to warm environments causes the momentum of mineral drugs to fail to disperse, internally obstructing the Zang-Fu organs. Struggling with normal Qi, this results in abdominal distension and fullness.
In cases where Wind-Lao (Wind consumption) was originally present, dispersing mineral drugs were taken. If the Wind-Lao is not fully resolved, the momentum of the mineral drugs erupts. After resolving the mineral toxicity, the body remains emaciated and weak, thus still harboring the pathogen of Wind-Lao.
After taking dispersing mineral drugs, if one drinks excessively, the momentum of the mineral drugs intensifies due to alcohol, spreading through the meridians and collaterals, causing irritability and fever.
The Classics state: Spring Qi is mild, Summer Qi is hot, Autumn Qi is cool, Winter Qi is cold; this is the sequence of the Righteous Qi of the four seasons. In winter, severe cold causes all things to hide deeply. If a gentleman guards closely, he will not be injured by cold. Those who violate and encounter it contract Cold Damage (Shang Han). Any invasion by the Qi of the four seasons can cause disease, but Cold Damage is considered the most toxic because it is the most lethal Qi. Those who fall ill immediately after infection are diagnosed with Cold Damage; those who do not fall ill immediately harbor the cold toxin within the muscle and bone. In spring, this transforms into Warm Disease (Wen Bing); in summer, it transforms into Summer Heat Disease (Shu Bing). Summer Heat Disease has heat that is heavier than that of Warm Disease. Therefore, hardworking people inevitably suffer from Warm Disease in spring and summer, caused by encountering cold in winter, not by the epidemic Qi. Epidemic Qi refers to situations where spring should be warm but is cold, summer should be hot but is cold, autumn should be cool but is hot, and winter should be cold but is warm—having the Qi of another season at the wrong time. Thus, throughout the year, patients of all ages suffer from similar illnesses; this is the Epidemic Qi.
Cold Damage disease originates from Wind-Cold, entering the Cou Li (interstices), struggling with Essence-Qi, causing stagnation and blockage of Ying (Nutritive) and Wei (Defensive) Qi, obstructing circulation. On the first or second day, the pathogen is between the orifices and skin, causing headache, aversion to cold, and stiffness/heaviness in the waist and back. This is pathogen in the exterior; bathing and inducing sweat leads to cure. On the third day or more, the Qi floats upward, filling the chest and heart, causing headache and chest fullness; purging (vomiting) leads to cure. On the fifth day or more, the Qi knots deeply in the Zang organs, causing abdominal distension, heaviness of the body, and painful joints; purgation leads to cure.
Heat diseases belong to the category of Cold Damage. Some recover, some die; death usually occurs between the sixth and seventh days, while recovery takes ten days or more. Why? Ju Yang (Tai Yang/Greater Yang) belongs to all Yang meridians, its vessels connect to Feng Fu (GV16), making it the master of Yang Qi. When humans are injured by cold, they develop heat disease; even with severe heat, they do not die. However, those suffering from "Liang Gan" (simultaneous injury of two meridians, typically exterior and interior) by cold will die. What are the pulse and symptoms of Liang Gan? On the first day, Ju Yang and Shao Yin (Lesser Yin) are both diseased, causing headache, dry mouth, and vexatious fullness. On the second day, Yang Ming (Bright Yang) and Tai Yin (Greater Yin) are both diseased, causing abdominal fullness, body heat, anorexia, and delirious speech. On the third day, Shao Yang (Lesser Yang) and Jue Yin (Terminal Yin) are both diseased, causing deafness, retraction of the scrotum, and cold limbs. If water and grain cannot enter and consciousness is lost, death occurs on the sixth day. After the five Zang organs are damaged, the six Fu organs are blocked, and Ying and Wei Qi do not circulate, death occurs three days later. Why? Yang Ming is the leader of the twelve meridians. Its Qi and Blood are abundant; thus, loss of consciousness persists for three days until its Qi is exhausted, leading to death.
For those not suffering from simultaneous injury: On the first day, Ju Yang receives the pathogen, causing head/neck pain and stiff spine/waist. On the second day, Yang Ming receives it; Yang Ming governs flesh, its vessels run along the nose and connect to the eyes, causing body heat, dry nose, and inability to sleep. On the third day, Shao Yang receives it; Shao Yang governs bones, its vessels follow the costal region and connect to the ears, causing chest/costal pain and deafness. If the three Yang meridians are diseased but have not entered the Zang, sweating can cure it. On the fourth day, Tai Yin receives it; Tai Yin vessels distribute to the stomach and connect to the throat, causing abdominal fullness and dry throat. On the fifth day, Shao Yin receives it; Shao Yin vessels pass through the Kidney, connect to the Lung, and tie to the root of the tongue, causing oral heat, dry tongue, and thirst. On the sixth day, Jue Yin receives it; Jue Yin vessels follow the genitalia and connect to the Liver, causing vexatious fullness and scrotal retraction. When the three Yin and three Yang, five Zang and six Fu are all diseased, Ying and Wei Qi stop, and the five Zang become blocked, leading to death. For those not suffering from simultaneous injury: On the seventh day, Ju Yang disease declines, headache lessens. On the eighth day, Yang Ming disease declines, body heat subsides. On the ninth day, Shao Yang disease declines, hearing slightly improves. On the tenth day, Tai Yin disease declines, abdomen reduces to normal, appetite returns. On the eleventh day, Shao Yin disease declines, thirst stops, no more fullness, dry tongue resolves, coughing begins. On the twelfth day, Jue Yin disease declines, scrotum descends slightly from the lower abdomen. The great pathogenic Qi departs, and the disease heals day by day.
How to treat? Treat by unblocking the meridians of each organ; the disease declines day by day. If the disease is less than three days old, sweating cures it; if over three days, purgation cures it. Tai Yang disease with headache lasting seven days or more will naturally heal as the meridian cycle ends. To prevent transmission to the next meridian, needle and tonify Yang Ming so transmission does not occur, ensuring cure.
The method of diagnosing involves observing color, listening to voice, and viewing the site of disease. The essentials of pulse diagnosis are subtle. A洪大 (Hong Da/Surging and Large) pulse indicates heat, characteristic of Cold Damage. A 洪浮 (Hong Fu/Surging and Floating) pulse in Cold Damage is favorable in autumn but prone to illness in spring. A tight pulse at Cun Kou indicates Cold Damage headache. A surging pulse indicates Cold Damage. In Shao Yin disease, aversion to cold, curled body, diarrhea, and cold limbs indicate untreatable condition; vomiting, diarrhea, restlessness, and rebellion indicate death. Cessation of diarrhea with dizziness and frequent fainting indicates death. Cold limbs, aversion to cold, curled body, absent pulse, and restlessness without vexation indicate death. High breathing on the sixth day of illness indicates death. In severe Cold Damage heat, a floating and large pulse indicates survival; sinking and small indicates death. Headache with short and choppy pulse indicates death; floating and slippery indicates survival. Without sweat, a surging and large pulse indicates survival; small and thin indicates death. In severe heat, a small pulse indicates untreatable death. In Cold Damage heat disease, a surging, restless pulse without sweat indicates extreme Yang, ten deaths out of ten. Without sweat, a restless pulse is difficult to treat; with sweat, survival is possible; without sweat, recovery is hard. Headache with reverse choppy pulse is adverse and untreatable; floating and large is easy to treat; fine and small is difficult.
After sweating, vomiting, or purging, or in cases of blood loss and fluid depletion, if Yin and Yang harmonize spontaneously, healing occurs. If purgation is followed by sweating and urination is difficult, this is fluid depletion; do not treat. If urination is free, self-healing occurs. If Yang is already deficient and Chi position pulse is weak, do not sweat. If the throat is dry, do not sweat. In Cold Damage, a string-tight and fine pulse with headache and fever indicates Shao Yang disease. Shao Yang disease must not be sweated; sweating causes delirium, indicating involvement of the Stomach. If Stomach Qi harmonizes, healing occurs; if not, vexation and palpitations arise. In Shao Yin disease, a fine, sinking, and faint pulse indicates interior disease; do not sweat. If the pulse is faint, do not sweat, as there is no Yang. If Yang is deficient and Chi pulse is weak and choppy, do not purge. In Tai Yang disease, fever with aversion to cold, more heat than cold, and weak pulse indicates absence of Yang; do not sweat. If the pulse is floating, sweating is permissible. Fever with spontaneous sweating and no aversion to cold, with a fine and rapid pulse at Guan position, contraindicates vomiting. For various cases of cold limbs, vomiting is contraindicated, as is for deficient individuals. More cold than heat may allow vomiting if due to excess phlegm. Treatment of Malaria follows similarly. If head/neck are not stiff, Cun pulse is slightly floating, there is obstruction in the chest, Qi rushes to throat preventing respiration, vomiting is indicated. To determine if purgation is suitable in Cold Damage, feel the pulse: if firm and solid, or unclear, check the palm. If the palm is sweaty, purgation is appropriate. If the palm is dry, although purgation might be indicated, wait, warm the body, ensure fluids circulate, and once the palm sweats, then purge. Tai Yin disease presents with abdominal fullness and vomiting food; do not purge, as it worsens the condition and causes periodic abdominal pain. If purged, hardness below the chest occurs; if pulse is floating, sweating is indicated. Yang Ming disease presents with hardness/fullness below the heart; do not purge, as it causes diarrhea and death; caution is essential.
When Tai Yang and Shao Yang diseases combine, with hardness below the heart, stiff/headache/dizziness, purgation is contraindicated. In San Yang combination disease, abdominal fullness, body heaviness, normal bowel/bladder function, and floating/firm/rapid pulse with thirst for water contraindicate purgation. Other methods like decoction warming, acupuncture, stone therapy, nourishment, and guidance are attached hereafter.
The *Yangsheng Fang · Daoyin Fa* states: Sit upright with straight waist, slowly inhale through the nose, hold the nose with the right hand, close eyes slowly, and exhale. This treats Cold Damage headache and chills, aiming for sweating.
It also states: Raise left hand, stomp left foot, palm up, inhale through nose forty times, then stop. This removes body heat and back pain.
