类中风者，谓火中、虚中、湿中、寒中、暑中、气中、食中、恶中也，共有八种。与真
中相类而实不同也。然类中有与真中相兼者，须细察其形证而辨之。凡真中之证，必连经络
多见歪斜偏废之候，与类中之专气致病者，自是不同。然而风乘火势，邪乘虚入。寒风相
搏，暑风相炫，饮食招风，种种变证，所在多有，务在详辨精细，果其为真中也，则用前驱
风法，果其为类中也，则照本门施治，果其为真中、类中相兼也，则以两门医法合治之，斯
无弊耳。兹举类中诸证，详列于下，俾学人触目洞然也。
一曰火中。火之自外来者，名曰贼，实火也。火之自内出者，名曰子，虚火也。中火之
证，良由将息失宜，心火暴盛，肾水虚衰，不能制之，故卒然昏倒，不可作实火论。假如怒
动肝火，逍遥散。心火郁结，牛黄清心丸。肺火壅遏，贝母栝蒌散。思虑伤脾，加味归脾汤
肾水枯涸，虚火上炎者，六味地黄汤。若肾经阳虚，火不归原者，八味地黄汤，刘河间
地黄饮子并主之。此治火中之法也。或问∶火中而用桂、附者，何也？答曰∶肾阳风越，则
丹田虚冷，其痰涎上壅者，水不归原也。面赤烦躁者，火不归原也。惟桂附八味能引火归原
火归水中，则水能生木，木不生风，而风自熄矣。
二曰虚中。凡人体质虚弱，过于作劳，伤损元气，以致痰壅气浮，卒然昏倒，宜用六君
子汤主之。中气下陷者，补中益气汤主之。
三曰湿中。湿中者，即痰中也。凡人嗜食肥甘，或醇酒乳酪，则湿从内受。或山岚瘴气
久雨阴晦，或远行涉水，坐卧湿地，则湿从外受。湿生痰，痰生热，热生风，故卒然昏倒
无知也。苍白二陈汤主之。
四曰寒中。凡人暴中于寒，卒然口鼻气冷，手足厥冷，或腹痛，下利清谷，或身体强硬
口噤不语，四肢战摇，此寒邪直中于里也。宜用姜附汤，或附子理中汤加桂主之。
五曰暑中。凡人务农于赤日，行旅于长途，暑气逼迫，卒然昏倒，自汗面垢，昏不知人
急用千金消暑丸灌之，其人立苏。此药有回生之功，一切暑药，皆不及此，村落中各宜预
备。灌醒后，以益元散清之，或以四味香薷饮，去浓朴，加丹参、茯苓、黄连治之。虚者，
加人参。余详论伤暑门。
六曰气中。七情气结，或怒动肝气，以致气逆痰壅，牙关紧急，极与中风相似，但中风
身热，中气身凉。中风脉浮，中气脉沉。且病有根由，必须细究。宜用木香调气散主之。
七曰食中。醉饱过度，或着恼怒，以致饮食填塞胸中，胃气不行，卒然昏倒，宜用橘红
二两，生姜一两，炒盐一撮，煎汤，灌而吐之，次用神术散和之。其最甚者，胸高满闷，闭
而不通，或牙关紧急，厥晕不醒，但心头温者，即以独行丸攻之，药即下咽，其人或吐或泻
自应渐苏。若泻不止者，以冷粥汤饮之，即止。
八曰恶中。登冢入庙，冷屋栖迟，以致邪气相侵，卒然错语妄言，或头面青黯，昏不知
人，急用葱姜汤灌之，次以神术散调之。苏合丸亦佳。

Lei Zhong Feng (Stroke-like syndrome) refers to Huo Zhong (Fire stroke), Xu Zhong (Deficiency stroke), Shi Zhong (Dampness stroke), Han Zhong (Cold stroke), Shu Zhong (Summerheat stroke), Qi Zhong (Qi stroke), Shi Zhong (Food stroke), and E Zhong (Evil/Toxic stroke), totaling eight types. They are similar to Zhen Zhong (True Stroke) but essentially different. However, Lei Zhong may coexist with Zhen Zhong; one must carefully observe symptoms and signs to differentiate them. True Stroke syndromes invariably involve meridians, often presenting with facial deviation or hemiplegia, which naturally differs from Lei Zhong caused solely by Qi disorders. Nevertheless, wind exploits fire, pathogens enter via deficiency. Cold wind clashes, summer heat wind conflicts, diet attracts wind; various complications occur frequently. One must distinguish meticulously. If it is truly Zhen Zhong, use the previously mentioned wind-dispelling methods. If it is indeed Lei Zhong, treat according to this chapter's methods. If it is a combination of both, combine treatments from both chapters to avoid errors. Here, we list the various syndromes of Lei Zhong in detail below, so that students may understand clearly at a glance.
The first is Huo Zhong (Fire Stroke). Fire coming from outside is called "Thief" (Zei), representing Excess Fire. Fire arising from within is called "Child" (Zi), representing Deficiency Fire. Huo Zhong occurs largely due to improper lifestyle management, where Heart Fire flares up violently while Kidney Water declines, failing to control the Fire, leading to sudden collapse. It should not be treated as Excess Fire. If anger stirs Liver Fire, use Xiaoyao San. If Heart Fire is constrained, use Niuhuang Qingxin Wan. If Lung Fire is obstructed, use Beimu Gualou San. If overthinking injures Spleen Qi, use Jiawei Guipi Tang. If Kidney Water is depleted with Deficiency Fire flaming upward, use Liuwei Dihuang Tang. If Kidney Yang is deficient with Fire not returning to its source, use Bawei Dihuang Tang; Liu Hejian's Dihuang Yinzi also treats this. This is the method for treating Huo Zhong. One might ask: Why use Guizhi (Cinnamon Twig) and Fuzi in Huo Zhong? The answer is: When Kidney Yang floats away, the Dantian becomes cold and empty, causing phlegm-saliva to obstruct upwards (Water not returning to source). Red face and irritability indicate Fire not returning to source. Only Guizhi and Fuzi in Bawei can guide Fire back to its source. Once Fire returns to Water, Water generates Wood; Wood does not generate Wind, and Wind extinguishes itself.
The second is Xu Zhong (Deficiency Stroke). In cases of weak constitution, excessive labor damages Yuan Qi, leading to phlegm obstruction and floating Qi, resulting in sudden collapse. Use Liujunzi Tang as the main formula. If Middle Qi sinks, use Buzhong Yiqi Tang.
The third is Shi Zhong (Dampness Stroke). Shi Zhong is synonymous with Tan Zhong (Phlegm Stroke). People who indulge in rich, sweet foods, strong wine, or dairy products accumulate Dampness internally. Or, exposure to mountain miasma, prolonged rainy gloom, traveling through water, or sitting/sleeping on damp ground causes external Dampness invasion. Dampness generates Phlegm, Phlegm generates Heat, Heat generates Wind, leading to sudden collapse and unconsciousness. Treat with Cangbai Erchen Tang.
The fourth is Han Zhong (Cold Stroke). Sudden invasion by Cold pathogen causes cold breath from mouth and nose, cold extremities, abdominal pain, diarrhea with undigested food, stiff body, locked jaw without speech, and trembling limbs. This is Cold pathogen directly invading the interior. Use Jiangfu Tang or Fuzi Lizhong Tang plus Guizhi.
The fifth is Shu Zhong (Summerheat Stroke). Farmers working under the scorching sun or travelers on long journeys suffer from oppressive Summerheat, leading to sudden collapse, spontaneous sweating, dirty complexion, and coma. Immediately administer Qianjin Xiaoshu Wan; the patient will revive instantly. This medicine has life-restoring power, superior to all other summerheat remedies. Villages should keep it in reserve. After reviving, clear residual heat with Yiyuan San, or Siwei Xiangru Yin removing Houpo, adding Danshen, Fuling, and Huanglian. For deficiency, add Renshen. See Shangshu Men for details.
The sixth is Qi Zhong (Qi Stroke). Emotional stagnation or anger stirring Liver Qi leads to rebellious Qi and phlegm obstruction, tight jaw, resembling stroke closely. However, Stroke presents with fever, while Qi Zhong presents with coolness. Stroke pulse is floating, Qi Zhong pulse is deep. The root cause must be investigated. Use Muxiang Tiaoqi San.
The seventh is Shi Zhong (Food Stroke). Overeating/drinking or anger causes food to block the chest, Stomach Qi fails to descend, leading to sudden collapse. Use 2 liang Juhong (Tangerine Peel), 1 liang Shengjiang, and a pinch of fried salt, decoct and induce vomiting. Then harmonize with Shenzhu San. In severe cases with high chest, fullness, blockage, locked jaw, or coma with warm heart, use Duxing Wan to purge. Upon swallowing, the patient may vomit or have diarrhea and gradually recover. If diarrhea persists, drink cold rice soup to stop it.
The eighth is E Zhong (Evil/Toxic Stroke). Visiting tombs or temples, staying in cold houses allows Evil Qi to invade, causing sudden delirium, dark/blueish face, and coma. Immediately administer Congjiang Tang (Green Onion and Ginger Decoction), then regulate with Shenzhu San. Suhexiang Wan is also excellent.
