戴人路经古亳，逢一妇，病喜笑不止，已半年矣。众医治者，皆无药术矣。求治
于戴人。戴人曰∶此易治也。以沧盐成块者二两，余用火烧令通赤，放冷研细；以河水一大碗
，同煎至三、五沸，放温分三次啜之；以钗探于咽中，吐出热痰五升；次服大剂黄连解毒汤
是也。不数日而笑定矣。《内经》曰∶神有余者，笑不休。此所谓神者，心火是也。火得风而成
焰，故笑之象也。五行之中，惟火有笑矣。
遂平李官人妻，病咽中如物塞，食不下，中满，他医治之不效。戴人诊其脉曰∶
此痰隔也。《内经》曰∶三阳结为隔。王启玄又曰∶格阳云阳盛之极，故食格拒而不入
。先以通经散，越其一半；后以舟车丸下之，凡三次，食已下；又以瓜蒂散再越之，健啖如昔日矣。
戴人女僮至西华，目忽暴盲不见物。戴人曰∶此相火也。太阳阳明，气血俱盛。
乃刺其鼻中攒竺穴与顶前五穴，大出血，目立明。
夫小儿悲哭，弥日不休，两手脉弦而紧。戴人曰∶心火甚而乘肺，肺不受其屈，
故哭。肺主悲。王太仆云∶心烁则痛甚。故烁甚悲亦甚。今浴以温汤，渍形以为汗也。肺主
皮毛，汗出则肺热散矣。浴止而啼亦止。乃命服凉膈散加当归、桔梗，以竹叶、生姜、朴硝
同煎服，泻膈中之邪热。
李氏一小儿，病手足搐搦，以示戴人。戴人曰∶心火胜也，勿持捉其手，当从搐
搦。此由乳母保抱太极所致。乃令扫净地以水洒之，干，令复洒之，令极湿；俯卧儿于地上
，良久，浑身转侧，泥 皆满；仍以水洗之，少顷而瘥矣。
戴人在路过古亳地时，遇到一位妇女，她患有喜笑不止的病证，已经持续半年了。其他医生治疗过，都无计可施。于是向戴人求治。戴人说：“这病容易治疗。”他用成块的沧盐二两，用火烧至通红，放凉后研成细粉；取一大碗河水，与盐同煎，煮沸三到五次，待温度适宜后分三次服用；然后用钗子探入咽喉催吐，吐出热痰五升；接着服用大剂量的黄连解毒汤。没过几天，她的笑声就停止了。《内经》说：“神有余的人，会笑个不停。”这里所说的“神”，指的是心火。火遇到风就会形成火焰，所以笑的形态就像火焰一样。在五行之中，只有火对应着笑。
遂平县李官人的妻子，患病感觉咽喉中有异物堵塞，饮食难下，胸脘痞满胀闷，其他医生治疗无效。戴人诊察她的脉象说：“这是痰隔病。”《内经》说：“三阳经气郁结会导致膈塞。”王启玄又说：“格阳是指阳气盛极，所以食物格拒不能进入。”先用通经散涌吐一半的痰涎；后用舟车丸泻下，共进行三次，食物得以咽下；再用瓜蒂散再次涌吐，患者恢复如往日般健食。
戴人的女仆到了西华县，眼睛突然暴盲，看不见东西。戴人说：“这是相火为患。”太阳经和阳明经气血俱盛。于是针刺她鼻中的攒竹穴以及头顶前五穴，放出大量血液，眼睛立刻复明。
有个小儿悲哭，整天不停，两手脉象弦而紧。戴人说：“心火旺盛而克制肺金，肺脏受不了这种委屈，所以哭泣。肺主悲。王太仆说：‘心火灼烁则疼痛剧烈。’所以灼烁严重，悲伤也严重。现在用温水洗澡，通过浸渍身体来发汗。肺主皮毛，出汗后肺热就消散了。停止洗澡后啼哭也就停止了。然后命令服用凉膈散加当归、桔梗，用竹叶、生姜、朴硝同煎服用，以泻除膈中的邪热。
李家的一个小孩，患手足抽搐痉挛的病，带给戴人看。戴人说：“这是心火胜克所致，不要强行控制他的手，应当顺应他抽搐的动作。”这是由于乳母怀抱保护过度造成的。于是让人扫净地面洒水，干了再洒，直到非常湿滑；让小儿俯卧在地上，过了很久，全身转动，泥水沾满全身；然后用清水冲洗，过了一会儿就好了。
While passing through Guobo, Dairen encountered a woman suffering from uncontrollable laughter for half a year. Other physicians had treated her without success. She sought treatment from Dairen. Dairen said, "This is easy to treat." He took two liang of block-form Cangyan (Halite), heated it in fire until red-hot, allowed it to cool, and ground it into fine powder; mixed it with one large bowl of river water, boiled it three to five times, let it cool to a warm temperature, and administered it in three doses; then used a hairpin to stimulate the pharynx to induce vomiting, expelling five sheng of hot phlegm; subsequently administered a large dose of Huanglian Jiedu Tang (Coptis Decoction for Detoxification). Within a few days, her laughter subsided. The *Neijing* states: "When Shen (Spirit) is in excess, there is incessant laughter." The "Shen" referred to here is Heart Fire. Fire becomes flame when encountering wind, thus the image of laughter resembles flame. Among the Five Elements, only Fire corresponds to laughter.
The wife of Official Li in Suiping County suffered from a sensation of obstruction in the throat, inability to swallow food, and abdominal fullness. Other treatments were ineffective. Dairen palpated her pulse and said, "This is Phlegm Obstruction (Tan Ge)." The *Neijing* states: "The binding of the Three Yang meridians leads to obstruction." Wang Qixuan further explained: "Ge Yang refers to extreme Yang excess, causing food to be rejected and unable to enter." First, Tongjing San (Unblocking Meridines Powder) was used to induce vomiting of half the phlegm; then Zhouche Wan (Boat and Cart Pill) was used to purge downwards, repeated three times, allowing food to pass; finally, Gudi San (Melon Seed Powder) was used again to induce vomiting, restoring her appetite as before.
Dairen's female servant suddenly went blind upon arriving in Xihua. Dairen said, "This is due to Ministerial Fire." The Taiyang and Yangming meridians have abundant Qi and Blood. Therefore, he punctured the Cuanzhu (BL2) acupoint in the nose and the five acupoints on the vertex, releasing a large amount of blood, and her vision immediately recovered.
A child cried bitterly day and night without cessation, with wiry and tight pulses in both hands. Dairen said, "Heart Fire is excessive and overacts on Lung Metal. The Lung cannot endure this oppression, hence the crying. The Lung governs grief. Wang Taipu stated: 'When Heart Fire scorches, pain is severe.' Thus, severe scorching leads to severe grief. Now, bathe him in warm water to induce sweating by soaking the body. The Lung governs the skin and hair; sweating dissipates Lung heat. Once bathing stopped, the crying also ceased. Then, order the administration of Liange San (Cooling Diaphragm Powder) added with Danggui (Angelica Sinensis) and Jiegeng (Platycodon), decocted with Zhuye (Bamboo Leaf), Shengjiang (Fresh Ginger), and Puxiao (Natrii Sulfas), to drain the pathogenic heat from the diaphragm.
A child of the Li family suffered from convulsions and spasms of the hands and feet, which Dairen examined. Dairen said, "This is caused by excessive Heart Fire. Do not forcibly restrain his hands; instead, follow the direction of the spasms." This condition resulted from the wet nurse holding and protecting the infant too tightly. Dairen ordered the floor to be swept clean and sprinkled with water; once dry, sprinkle again until extremely wet; place the infant prone on the ground, and after a long while, as the child turns and rolls, mud covers the whole body; then wash with water, and shortly thereafter, the condition resolved.
