或问∶不语，有心脾肾三经之异；又风寒客于会厌，亦令不语，何以辨之？愚谓心者，
君主之官，神明出焉。若心经不语，必昏冒全不知人，或兼直视、摇头等症，盖心不受邪，
受邪则殆，此败症也。若胞络受邪，则时昏时醒，或时自喜笑。若脾经不语，则人事明白，
或唇缓，口角流涎，语言謇涩。若肾经不语，则腰足痿痹，或耳聋遗尿，以此为辨。至若风
寒客于会厌，不过喊风声哑之属，口能收，舌能转，枢机皆利，但不发音耳，可用辛散而安
中风者，真中风也。类中风者，似中风而非中风也。然真中有兼类中者，类中有兼真中
者，临证最难分别，不可无法以处之。大法中风之证，有中腑、中脏、中血脉之分，前论已
详言矣。惟类中与真中，最宜分别，不可不审。真中风者，中于太阳，则与伤寒外感传经相
符。若中血脉，必有偏枯 斜之证，中脏虽为在里，亦必兼有经络偏枯之证。若类中者，寒
则厥冷、呕泻而暴痛也；暑则赤日中行而卒倒也；湿则痰涎壅盛而闭塞也；火则面赤、烦渴
、唇燥而便闭也；食则因于过饱，而胸胀满闷也；气则因于盛怒而闭塞无音也；恶则因登冢
入庙，冷屋栖迟，而卒然头面青黯也；虚则面色 白、鼻息轻微也。见证各殊，与真中
之偏枯、 斜自是不同。其间或有相同者，乃真中、类中相兼也。症既相兼，必须一一辨明
，察其多寡兼并之处，辨其标本缓急之情，审度得宜，用古人经验良方，随手而起矣。
有人问：失语，有心、脾、肾三经的不同；另外风寒侵袭会厌，也会导致失语，如何辨别呢？我认为心是君主之官，精神意识由此产生。如果是心经受邪导致的失语，必然伴有神志昏迷、完全不知人事的症状，或者兼有直视、摇头等症，因为心本不受邪，受邪则危险，这是败坏的证候。如果是心包络受邪，则时而昏迷时而清醒，或者时而自行喜笑。如果是脾经受邪导致的失语，则神志清楚明白，或者口唇松弛，口角流涎，语言蹇涩不利。如果是肾经受邪导致的失语，则腰足痿软痹痛，或者耳聋遗尿，以此作为辨别依据。至于风寒侵袭会厌，不过是发出喊声时声音嘶哑一类，口能闭合，舌能转动，气机枢纽通畅，只是不能发出声音罢了，可以使用辛温发散的药物来治疗。
中风病，是指真中风。类中风病，是指像中风但不是中风。然而真中风中可能兼有类中风的证候，类中风中也可能兼有真中风的证候，临证时最难区分，不能没有方法来处理。大凡中风的证候，有中腑、中脏、中血脉的区别，前面的论述已经详细说过了。只有类中风与真中风，最应当分别，不可不审慎。真中风，是邪气中于太阳经，则与伤寒外感传经的规律相符。如果中于血脉，必然有半身不遂、口眼歪斜的症状；中于脏腑虽然病位在里，但也必然兼有经络偏枯的症状。如果是类中风，寒邪所致则四肢厥冷、呕吐腹泻且突发疼痛；暑邪所致则在烈日下行走而突然昏倒；湿邪所致则痰涎壅盛且闭塞不通；火邪所致则面红、烦渴、嘴唇干燥且大便闭结；食积所致是因为过饱，导致胸腹胀满闷堵；气滞所致是因为大怒而导致闭塞无声；恶毒（或指秽浊之气）所致是因为登上坟墓进入庙宇，在阴冷的屋子逗留，而突然头面部青暗；虚证所致则面色苍白、鼻息微弱。见证各不相同，与真中风的偏枯、口眼歪斜自然不同。其中或许有相同的症状，那是真中与类中相兼的情况。症状既然相兼，必须一一辨明，观察其多寡兼并之处，辨别其标本缓急的情况，审度得当，使用古人经验良方，就能随手奏效了。
A question arises: Aphasia (loss of speech) differs among the Heart, Spleen, and Kidney meridians; furthermore, Wind-Cold invading the epiglottis also causes aphasia. How can these be distinguished? I hold that the Heart is the Sovereign Official, from which Spirit (Shen) emerges. If aphasia results from the Heart meridian being affected, there must be complete coma and unconsciousness, or accompanied by symptoms such as staring fixedly and shaking the head. This is because the Heart does not easily accept pathogenic factors; if it does, the condition is perilous, representing a critical failure syndrome. If the Pericardium (Bao Luo) accepts the pathogen, the patient may alternate between coma and consciousness, or laugh spontaneously at times. If aphasia results from the Spleen meridian, the patient remains mentally clear, but may present with flaccid lips, drooling from the corner of the mouth, and slurred speech. If aphasia results from the Kidney meridian, there will be flaccidity and numbness in the waist and feet, or deafness and urinary incontinence; these serve as the basis for differentiation. As for Wind-Cold invading the epiglottis, this merely belongs to cases of hoarseness when shouting. The mouth can close, the tongue can move, and the pivot mechanism remains unobstructed; only sound production is impaired. Such cases can be treated with acrid-diffusing methods.
Zhong Feng (Stroke), refers to True Stroke. Lei Zhong Feng (Stroke-like Syndrome) refers to conditions resembling stroke but are not true stroke. However, True Stroke may have concurrent Lei Zhong features, and Lei Zhong may have concurrent True Stroke features. Differentiating them clinically is most difficult, so methods must be established to handle them. Generally, Zhong Feng syndromes are divided into involvement of the Fu organs, Zang organs, and Channels and Collaterals, as detailed in previous discussions. It is crucial to distinguish carefully between Lei Zhong and True Stroke. True Stroke involves invasion of the Taiyang channel, consistent with the transmission patterns of external contraction Cold damage (Shang Han). If it affects the channels and collaterals, there must be hemiplegia (Pian Gu) and facial deviation (Xie Bi). Although involvement of the Zang organs implies an interior location, it must also be accompanied by signs of channel/collateral hemiplegia. In contrast, Lei Zhong caused by Cold presents with cold extremities, vomiting, diarrhea, and sudden pain; caused by Summerheat, it presents as sudden collapse while walking under the scorching sun; caused by Dampness, it presents with excessive phlegm-saliva accumulation and obstruction; caused by Fire, it presents with red face, irritability, thirst, dry lips, and constipation; caused by Food Retention, it results from overeating leading to chest fullness and stuffiness; caused by Qi Stagnation, it results from extreme anger leading to obstruction and silence; caused by Malicious/Noxious influences (such as visiting tombs or temples, or lingering in cold houses), it presents as sudden cyanosis of the head and face; caused by Deficiency, it presents with pale complexion and faint nasal breathing. These manifestations differ distinctly from the hemiplegia and facial deviation of True Stroke. Where symptoms may appear similar, it indicates a combination of True and Lei Zhong. When symptoms combine, each must be clearly differentiated. One must observe the predominance and co-occurrence of factors, discern the root and branch, and the urgency and slackness of the condition. With proper assessment, applying time-honored effective formulas will yield immediate results.
