张仲景说：伤寒病经过三四天，邪气尚未传入里部，邪气位于上部，使用瓜蒂散催吐即可痊愈。怎么可以等待发汗呢？又说：伤寒六七天，胸中微有痞塞感，不想说话，心中烦闷懊恼、头晕目眩，没有可下的证候，张仲景使用栀子豉汤催吐，立刻见效。又比如突然中风，人事不知，也不需发汗，喉中有痰鸣声，使用稀涎散催吐，也可以。又有小儿惊风潮搐，手足抽搐拘挛，使用验命散催吐。又说：风头痛，经书说如果不吐出痰涎，时间久了会导致失明且无法治疗，使用瓜蒂散催吐，吐三次即愈。又比如突发咳嗽，风痰上壅，咽喉噎塞不利，使用茶调散催吐。
还有阳痫久治不愈，尚未形成痴呆，使用导涎散催吐。阴痫，使用二圣散催吐。
还有饮食肥甘厚味的人，多吃生冷鱼脍，食物停滞胸中不下，化生寄生虫伏于胸中，胸膈不适，吞咽困难，使用藜芦散催吐。
还有久病患者胁痛，各种药物不能治愈，使用独圣散加蝎梢半钱催吐。
人刚患伤食，或因冷身导致腹部闷乱，身体发热，见食物则呕吐，使用赤小豆散催吐。
有人问：筋病为什么要用吐法？回答说：木郁达之，所谓“达”，就是使其条达舒展的意思。或者又有因打扑坠堕受伤，先用金花散催吐，后用承气汤泻下。所谓“承”，就是顺应的意思。
偏枯证，就是半身不遂，使用追风散催吐。如果中风后有眼疾，眼睛半明，可以救治，使用防风汤催吐。
各种风病引起的肢体摇动强直，人事不知，就可以使用悬豆膏，引出痰涎后立刻见效。
胸膈满闷，背痛或臂痛，可先用祛风汤催吐，后服用乌药散。疠风或疮疡恶疮，就使用二圣散催吐，后服用苦参丸。
各种厥气导致的厥中风，不省人事，就使用神圣散膏，从鼻腔灌入，吐出痰涎后立刻见效。
破伤风，牙关紧急，角弓反张，就给予神圣散催吐，随后发汗、泻下也有效，三种方法都使用。
又有人患蛟龙瘕痛，久治不愈想死，使用球糖膏催吐，吐出物体形状像蜥蜴，长七八寸，立刻痊愈。
吐法，是上古高明医生使用的。如今平庸低劣的医生，只看各方，不懂治法，不认识病源，就不施行圣人的法则，离圣人之道太远了。能不恐惧吗？
Zhang Zhongjing stated: In cold damage (Shanghan) after three or four days, if the pathogenic factor has not yet transmitted to the interior and remains in the upper jiao, use Gouti San (Melon Seed Powder) to induce vomiting for recovery. How can one wait for sweating? He also stated: In cold damage after six or seven days, if there is slight fullness in the chest, reluctance to speak, mental restlessness and oppression (Ao Nao), dizziness, and no signs indicating purgation, Zhang Zhongjing used Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction) to induce vomiting, with immediate effect. Similarly, in sudden wind-stroke where consciousness is lost, sweating is not required; if there is phlegm-rattling sound in the throat, use Xixian San (Sputum-Dissipating Powder) to induce vomiting, which is also effective. For pediatric convulsive disorders with tidal spasms and limb flexion/spasm, use Yanming San (Life-Verifying Powder) to induce vomiting. Regarding wind-induced headache, the classics state that if phlegm-drool is not vomited out, blindness may occur eventually and become incurable; use Gouti San to induce vomiting, recovering after three doses of vomiting. In cases of sudden cough with wind-phlegm obstructing upwards, causing throat blockage and difficulty in swallowing, use Chatiao San (Tea-Regulating Powder) to induce vomiting.
For Yang epilepsy that persists without cure but has not yet developed into dementia, use Daoxian San (Phlegm-Guiding Powder) to induce vomiting. For Yin epilepsy, use Ersheng San (Two Sages Powder) to induce vomiting.
For individuals consuming rich foods and raw fish/sashimi excessively, leading to food stagnation in the chest, transformation of parasites lodging in the chest, chest-diaphragm discomfort, and dysphagia, use Lilu San (Veratrum Powder) to induce vomiting.
For chronic patients suffering from hypochondriac pain unresponsive to various medicines, use Dusheng San (Single Sage Powder) added with half a qian of Scorpion tail (Xie Shao) to induce vomiting.
For epileptic seizures occurring irregularly with loss of consciousness, use Bansheng Banshu Tang (Half-Raw Half-Cooked Decoction) to induce vomiting.
For "An Feng" (hidden wind disease) persisting without cure, where the patient returns to normal after an episode, use Yujin San (Curcuma Powder) to induce vomiting.
For malaria persisting without cure, with irregular chills and fever, use Changshan San (Changshan Powder) to induce vomiting.
For "Jiaolong Jia" (abdominal mass resembling a dragon) causing pain and abdominal distension resembling Gu toxicity, use Qiutang San (Ball-Sugar Powder) to induce vomiting.
When initially suffering from food stagnation, or experiencing abdominal stuffiness and confusion due to cold exposure, with body heat and vomiting upon seeing food, use Chixiaodou San (Red Bean Powder) to induce vomiting.
For women suffering from tendon spasm and bone pain, use Shenyingsan (Miraculous Response Powder) to induce vomiting.
Someone asked: Why induce vomiting for tendon diseases? The answer is: "Wood depression should be dispersed." The term "disperse" here means allowing it to flow freely and smoothly. In cases of trauma from falls or blows, first induce vomiting using Jinhua San (Golden Flower Powder), then purge downwards using Chengqi Tang (Inheriting Qi Decoction). The term "Cheng" implies following or accommodating.
For Pian Ku syndrome (hemiplegia), use Zhuifeng San (Wind-Chasing Powder) to induce vomiting. If post-stroke eye disease occurs with partial vision restoration, it can be treated using Fangfeng Tang (Saposhnikovia Decoction) to induce vomiting.
For pediatric upper wheezing and tidal fever, first use Weijin San to induce vomiting, then use Zhen Ting San to purge downwards, yielding immediate results.
For treating mania and insanity persisting without cure, use Sansheng San (Three Sages Powder) to induce vomiting, followed by strong purgation.
For wind syndromes causing tremors, shaking, stiffness, and loss of consciousness, apply Xuandou Gao (Hanging Bean Paste); once phlegm is expelled, immediate effect is seen.
For chest-diaphragm fullness and oppression, back pain, or arm pain, first use Qufeng Tang (Wind-Expelling Decoction) to induce vomiting, then take Wuyao San (Lindera Powder). For Leprosy or malignant sores, use Ersheng San to induce vomiting, then take Kushen Wan (Sophora Pill).
For various Jue syndromes and wind-stroke resulting in loss of consciousness, apply Shensheng San Gao (Divine Sage Paste) into the nasal cavity; vomiting out phlegm yields immediate results.
For Tetanus (Po Shang Feng) with lockjaw and opisthotonos, administer Shensheng San to induce vomiting; subsequent sweating and purgation are also effective. All three methods should be employed.
Another case involved severe abdominal pain from "Jiaolong Jia" persisting until near death; using Qiutang Gao induced vomiting of an object resembling a lizard, 7-8 cun long, resulting in immediate recovery.
The vomiting method was used by high physicians of ancient times. Today, mediocre practitioners merely look at prescriptions, do not understand treatment principles, fail to recognize disease origins, and thus do not practice the methods of the Sages, drifting far from their teachings. Should one not fear this?
