夫冒风、时气、温病、伤寒，三日以里，头痛身热恶寒，可用通圣散、益元散
各五、七钱，水一大碗，入生姜十余片，葱白连须者十余茎，豆豉一撮，同煎三、五沸，去滓，稍热，先
以多半投之；良久，用钗子于咽喉中探引吐了，不宜漱口；次用少半，亦稍热投之，更用葱
醋酸辣汤投之，衣被盖覆，汗出则愈矣。如遇世乱，《内经》曰∶岁火太过，炎暑流行，火
气太盛，肺金受邪，上应荧惑，大而明现，若用辛凉之剂解之，则万举万全也。若遇治世人安，
可用升麻汤、葛根汤、败毒散，辛温之剂解之。亦加葱根白、豆豉，上涌而表汗。《内经》
曰∶因其轻而扬之。扬者，发扬也。吐汗发扬寒热之邪。既吐汗之后，必大将息，旬日
之后，其邪不复作也。又一法，或于无药之处，可用酸齑汁一大碗，煎三、五
，去菜叶，猛服讫；少间，用钗子咽喉中探引吐了，如此三次；后煎葱酸辣汤投之，以衣被
盖覆，汗出则解。《内经》曰∶酸苦涌泄为阴。涌者，吐也。伤寒三日，头痛身热，是病
上也。在上者，固宜涌之，然后以淡浆粥养之，一、二日则愈矣。
又一法，可用不卧散解之，于两鼻内闻之，连嚏喷三、
二十次，以衣被盖覆。用此药时，当于暖室中，嚏罢，以酸辣浆粥投之，汗出如洗。嚏喷者
，用吐法也。此法可与双解散为表里也。
又有导引一法，可于一闲处用之。先教病患盘脚而坐，次用两手交十指，攀脑后风池风府，
二穴乃是风门也；向前叩首，几至于地，如此连点一百二十数；急以葱醋粥辛辣汤投之，汗出立解。
伤寒、温疫、时气、冒风、中暑，俱四时不正之气也。人若初感之，皆头痛、恶寒、身热，
及寒热往来，腰脊强，是太阳经受之也。《内经》曰∶可先治外而后治内。先用生姜、葱白、豆豉煎双解
散，上涌及汗出则解。如不解者，至五、六日，或不大便，喘满 语实热，两手脉沉，可用
调胃、大、小承气汤下之，慎不可用银粉、巴豆霜、杏仁、芫花热药，下之则必死。此先治
外，而后治内也。如大汗
之后，慎不可食葵羹、藿菜及羊、猪、鸡、犬、鱼、兔等肉。惟不先明，必致重困，后必难
治也。伤寒七、八日，发黄有斑，潮热腹满者，或痰实作止，虽诸承气汤下过者，仲景曰∶寸口脉浮滑者，可用
瓜蒂散吐之。然伤寒寸口脉浮滑者可用，杂病寸口脉沉者可吐。叔和云∶寸脉沉兮胸有痰
。启玄子曰∶上盛不已，吐而夺之是也。
火邪，是由少阳相火所主导的。其症状包括：各种突然发生的死亡、发热恶寒、疼痛剧烈发作、转化为水肿、面色发黄身体萎软、排泄脓血、赤白痢疾、痈肿疽毒、丹毒疮疡疹子、小儿疳积腹泻、腹胀、突然腹泻如水样、心胸中烦热，严重时出现鼻塞鼻出血、胸胁部疼痛、耳聋口苦舌干，以及脏毒下血、米谷不消化、肠鸣切痛、消渴伴上气喘促，这是肺金受病。
可用方剂：凉膈散、黄连解毒汤、泻心散、神芎丸、八正散、调胃散、调胃承气汤。
燥邪，是由阳明燥金所主导的。其症状包括：各种气机郁滞、肠胃干燥枯竭、皮肤皱裂脱屑、胁肋疼痛、寒性疟疾、喘咳、腹中肠鸣、急泻便溏、胁肋突发剧痛、不能翻身侧卧、咽喉干燥面部如蒙尘垢、肌肉消瘦面色枯槁，以及男子疝气、妇人少腹痛、赤白带下、疮疡痤疮疖肿、喘咳潮热、大便涩滞干燥，以及马刀挟瘿等疮疡，这是肝木受病。
可用方剂：神功丸、脾约丸、麻仁丸、润体丸、四生丸。
寒邪，是由太阳寒水所主导的。其症状包括：各种寒冷湿痹、肘臂拘挛紧急、秋季湿气多时引发的寒咳、痰厥心痛、心中悸动不安、胸胁胃脘疼痛无法进食、吃完后不觉得饿、呕吐泄泻物腥臭秽浊、屈伸不便、上下二便失禁、目盲、坚硬痞块、面色黑晦、口渴想喝冷水且体内积水、足部浮肿、阴囊收缩、四肢冰冷、指甲青紫，这是心火受病（注：此处原文逻辑为寒邪伤阳导致心火衰微或心阳不振之象，虽言心火为病，实指寒盛伤阳）。
可用方剂：姜附汤、四逆汤、二姜汤、术附汤、大已寒丸、理中汤。
对于冒风、时气、温病、伤寒，在发病三日以内，出现头痛、身热、恶寒的症状，可以使用通圣散、益元散各五到七钱，加水一大碗，放入生姜十余片、带根的葱白十余茎、豆豉一撮，一同煎煮三至五次沸腾，滤去药渣，稍加热，先服用大半碗；过一段时间后，用发钗在咽喉中探引催吐，不宜漱口；接着服用剩下的小半碗，也稍加热后服用，再用葱醋酸辣汤送服，盖上衣被，出汗后即可痊愈。如果遇到世道混乱，《内经》说：岁火太过，炎暑流行，火气太盛，肺金受邪，天上对应荧惑星大而明亮，此时若用辛凉的药物来解表，则万无一失。如果遇到治世安宁，可以使用升麻汤、葛根汤、败毒散，这些是辛温的药物来解表。也可以加入葱根白、豆豉，通过涌吐和发汗的方法解表。《内经》说：因其轻而扬之。扬者，发扬之意。通过涌吐和发汗来发散寒热之邪。在涌吐和发汗之后，必须注意调养，十天之后，邪气就不会再复发了。另一种方法，如果在没有药物的地方，可以用酸醋汁一大碗，煎煮三至五次沸腾，去掉菜叶，猛喝下去；过了一会儿，用发钗在咽喉中探引催吐，如此三次；之后再煎葱醋酸辣汤送服，盖上衣被，出汗即可解除。《内经》说：酸苦涌泄为阴。涌者，即吐。伤寒三日，头痛身热，这是病邪在上焦。病在上焦，本来适宜用涌吐法，然后用淡浆粥来滋养，一两天就好了。
又一种方法，可以使用不卧散来解表，将其粉末吸入两个鼻孔内，连续打喷嚏三二十次，然后盖上衣被。使用此药时，应当在温暖的房间中进行，打完喷嚏后，用酸辣浆粥送服，出汗如雨。打喷嚏，是使用涌吐法的一种表现。这种方法可以与双解散互为表里。
还有一种导引法，可以在空闲的地方使用。先教患者盘腿而坐，然后两手交叉十指，攀抓脑后的风池穴和风府穴，这两个穴位乃是风门所在；向前叩首，几乎接近地面，如此连续点首一百二十次；急忙用葱醋粥辛辣汤送服，出汗后立即解除。
伤寒、温疫、时气、冒风、中暑，都是四季中不正之气。人如果刚感受这些邪气，都会出现头痛、恶寒、身热，以及寒热往来、腰脊强直，这是太阳经受邪。《内经》说：可以先治外而后治内。先用生姜、葱白、豆豉煎煮双解散，通过涌吐和发汗来解除。如果不解除，到了第五六天，或者不大便、喘满、谵语、实证热证，两手脉象沉，可以使用调胃承气汤、大承气汤、小承气汤来攻下，千万不要用银粉、巴豆霜、杏仁、芫花等热药攻下，否则必死。这是先治外，而后治内的方法。在大汗之后，千万不可吃葵菜羹、藿香菜以及羊、猪、鸡、狗、鱼、兔等肉类。如果不事先明白这一点，必定导致病情加重，后来就难治了。伤寒七八日，出现发黄有斑、潮热腹满的情况，或者痰实发作停止，虽然已经用过各种承气汤攻下，张仲景说：寸口脉浮滑的，可以用瓜蒂散来催吐。然而伤寒寸口脉浮滑的可以用此法，杂病寸口脉沉的可吐。王叔和说：寸脉沉说明胸中有痰。启玄子说：上盛不已，应当用吐法来夺其邪。
Fire pathogen is governed by the Ministerial Fire of Shaoyang (Lesser Yang).

Its manifestations include various qi stagnation and depression, dryness and depletion of the intestines and stomach, wrinkling and peeling of the skin, hypochondriac pain, cold malaria, asthma and cough, borborygmus in the abdomen, urgent diarrhea with loose stools, sudden severe pain in the hypochondrium making turning difficult, dry throat, dusty face, muscle wasting with poor complexion, hernia in men, lower abdominal pain and red/white leukorrhea in women, sores, acne, furuncles, asthma with tidal fever, dry and constipated stool, and sores like "horse knife" and "clenched goiter", indicating liver wood pathology.
Available formulas: Shengong Wan (Divine Merit Pill), Pi Yue Wan (Spley Restriction Pill), Maren Wan (Hemp Seed Pill), Runti Wan (Moisten Body Pill), Sisheng Wan (Four Generations Pill).
Cold pathogen is governed by the Cold Water of Taiyang (Greater Yang). Its manifestations include various cold-damp bi syndrome, spasm and stiffness of elbows and arms, cold cough due to autumn dampness, phlegm-jue heart pain, palpitations in the heart, pain in the chest, hypochondrium, and epigastrium preventing eating, lack of appetite after eating, vomiting and diarrhea with foul-smelling excreta, difficulty in flexion and extension, incontinence of urine and feces, blindness, hard masses, sallow/dark complexion, thirst craving cold water with fluid retention, swollen feet, retracted scrotum, cold limbs, cyanotic nails, indicating heart fire pathology (due to cold damaging yang).
Available formulas: Jiangfu Tang (Ginger and Aconite Decoction), Sini Tang (Reverse the Yin Decoction), Erjiang Tang (Two Gingers Decoction), Zhufu Tang (Atractylodes and Aconite Decoction), Da Yihan Wan (Great Cold-Resolving Pill), Lizhong Tang (Regulate the Middle Decoction).
For conditions such as wind-capture, seasonal qi disorders, warm diseases, and cold damage within three days of onset, presenting with headache, fever, and aversion to cold, Tongsheng San (Unimpeded Holy Powder) and Yiyuan San (Benefit Origin Powder) can be used, five to seven qian each, boiled in one large bowl of water with over ten slices of fresh ginger, over ten stalks of green onion whites with roots, and a pinch of fermented soybeans. After boiling three to five times, strain the dregs, warm slightly, and administer more than half first; after some time, induce vomiting by probing the throat with a hairpin, without rinsing the mouth; then administer the remaining small portion, also warmed, followed by green onion vinegar spicy soup, cover with blankets, and cure upon sweating. If encountering chaotic times, as stated in *Neijing*: when annual fire is excessive, hot summer heat prevails, fire qi is too strong, and lung metal is attacked, corresponding to the bright appearance of Mars; using acrid-cool agents to resolve it ensures success. In peaceful times, Shengma Tang (Cimicifuga Decoction), Gegen Tang (Pueraria Decoction), and Baidu San (Defend Against Poison Powder), which are acrid-warm agents, can be used to resolve the exterior. Adding green onion roots/whites and fermented soybeans allows for resolving via vomiting and sweating. As *Neijing* states: "Treat light pathogens by dispersing them." Dispersing means uplifting. Vomiting and sweating disperse cold and heat pathogens. After vomiting and sweating, strict rest is required; after ten days, the pathogen will not recur. Another method: if no medicine is available, use one large bowl of sour vinegar juice, boil three to five times, remove vegetable leaves, drink rapidly; after a while, induce vomiting by probing the throat with a hairpin, repeat three times; then drink green onion vinegar spicy soup, cover with blankets, and cure upon sweating. As *Neijing* states: "Acid and bitter promote upward and downward discharge, belonging to Yin." Upward refers to vomiting. Cold damage within three days with headache and fever indicates pathogen in the upper jiao. Pathogens in the upper jiao should be treated with vomiting, followed by nourishment with thin rice gruel; recovery occurs in one or two days.
Another method: use Buwo San (Do Not Sleep Powder) by insufflating powder into both nostrils, inducing thirty to twenty sneezes, then cover with blankets. Use this medicine in a warm room; after sneezing, drink spicy sour rice gruel, sweating profusely. Sneezing is a form of vomiting therapy. This method corresponds internally and externally to Shuangjie San (Double Resolution Powder).
Another guiding exercise method can be used in a quiet place. Teach the patient to sit cross-legged, interlock fingers, grasp the Fengchi (Wind Pool) and Fengfu (Wind Court) acupoints at the back of the head, which are gates of wind; bow forward until nearly touching the ground, repeating one hundred and twenty times; immediately drink spicy green onion vinegar porridge, and recover upon sweating.
Cold damage, warm plague, seasonal qi, wind-capture, and heatstroke are all improper qi of the four seasons. Initial infection presents with headache, aversion to cold, fever, alternating chills and fever, and stiff waist/spine, indicating Taiyang channel involvement. As *Neijing* states: "Treat the exterior first, then the interior." First use Shuangjie San (Double Resolution Powder) decocted with ginger, green onion whites, and fermented soybeans to resolve via vomiting and sweating. If unresolved, on day five or six, with constipation, asthma/fullness, delirium, excess heat, and deep pulses in both hands, use Tiaoweichengqi Tang (Regulate the Stomach and Direct Downward Decoction), Dachengqi Tang (Major Direct Downward Decoction), or Xiaochengqi Tang (Minor Direct Downward Decoction) to purge. Strictly avoid silver powder, croton seed frost, apricot kernels, and genkwa root (hot purgatives); purging with these leads to death. This is treating the exterior first, then the interior. After heavy sweating, strictly avoid mallow soup, huoxiang vegetables, and meats of sheep, pig, chicken, dog, fish, rabbit. Ignorance of this leads to severe distress and difficult treatment later. On day seven or eight of cold damage, with jaundice, spots, tidal fever, and abdominal fullness, or intermittent phlegm-excess, even if previously purged with Chengqi Decoctions, Zhang Zhongjing states: if Cun Kou pulse is floating and slippery, Gouti San (Melon Seed Powder) can be used to vomit. However, for cold damage, floating-slippery Cun Kou pulse allows this; for miscellaneous diseases, sinking Cun Kou pulse allows vomiting. Wang Shuhe said: "Sinking Cun pulse indicates phlegm in the chest." Qixuanzi said: "Excessive upper fullness requires vomiting to drain the pathogen."
