人口眼 斜，皆血脉受病，有筋病脉病之分，多属胃土也。《经》曰∶足阳明与手
太阳筋急，则目为僻 急不能正视，是胃上之筋病 斜也。又曰∶足阳明之脉，挟口环
唇，是胃上之脉病 斜也。以口目常动，故风生焉。耳鼻常静，故风息焉。然筋者，血
所养，脉者血之府，《经》云∶脉勿荣则筋急。兼之邪乘虚袭，中于寒则筋急引颊，口
目歪；中于风热则筋脉纵缓，或燥槁牵引，皆令 僻。然气血无病，则虽热未必
缓，虽寒未必急，其寒其热，多由气血之虚所致，故不必以偏于左者，为左寒右热，偏
于右者为右寒左热。凡拘急之所，即气血所亏之处，总之，寒者病也，热者气也。气所
不及之处，即为寒矣、病矣，岂有一经而寒热之邪并中，一病而寒热之气两殊者耶？明
乎此，则凡百病之客乎一人也。虽有症候错杂，究其原则在一也。
《灵枢》言∶足阳明之筋，颊筋有寒则急引，有热则筋弛纵，故左寒右热，则左急
而左缓，右寒左热，则右急而左缓，阳气不得宣行故也。《经》曰∶邪之所凑，其气必
虚，偏枯 僻，或左或右，血脉不周，而气不匀也。治宜补正气，行滞气，疏风气，使
气匀则风顺矣。

口眼歪斜，都是血脉受到病邪侵袭所致，有筋病和脉病的区别，大多与胃土有关。《黄帝内经》说：足阳明经和手太阳经的筋脉拘急，就会导致眼睛偏斜、紧急而不能正视，这是胃部经脉上的筋病引起的口眼歪斜。又说：足阳明经的脉道，环绕口唇，这是胃部经脉本身的病变导致的口眼歪斜。因为口和目经常活动，所以容易生风；鼻和耳经常静止，所以风邪不易停留。然而，筋是由血液滋养的，脉是血液汇聚的场所，《内经》说：如果脉中气血不能荣养，筋就会拘急。再加上邪气乘虚而入，如果中于寒邪，则筋脉拘急牵引脸颊，导致口眼歪斜；如果中于风热之邪，则筋脉弛缓松弛，或者干燥枯槁牵引，都会导致口眼歪斜。但是，如果气血没有亏损，那么即使受热也不一定弛缓，受寒也不一定拘急，其寒热表现，多是由气血虚弱所导致的，所以不必认为偏向左侧的就是左寒右热，偏向右侧的就是右寒左热。凡是出现拘急的地方，就是气血亏虚的地方。总之，寒属于病邪，热属于气分异常。气所不及之处，就是寒邪所在，也就是病变所在，难道会有一经受寒热两种邪气同时侵犯，一种病却有寒热两种不同气机表现的情况吗？明白了这个道理，那么各种疾病客居在一个人身上，虽然有症状错杂复杂，但究其根本原则在于一个“虚”字。
《灵枢》说：足阳明经的筋，颊部的筋如果有寒邪就会拘急牵引，如果有热邪就会筋脉弛缓松弛，所以左寒右热，则左侧拘急而右侧弛缓；右寒左热，则右侧拘急而左侧弛缓，这是因为阳气不能宣通运行所致。《内经》说：邪气聚集的地方，正气必然虚弱，半身不遂或口眼歪斜，或左或右，是因为血脉运行不周遍，气机不均匀。治疗应当补益正气，行滞气，疏风气，使气机均匀，那么风邪自然平息。
王节斋说：有人在饮食过饱之后，或者感受风寒，或者遭遇气恼，食物停滞在太阴脾经，胃气不能运行，片刻之间发生厥逆，昏迷不省人事，名叫食厥。如果误当作中风或中气治疗，病人会立即死亡，只能用阴阳淡盐汤催吐，食物吐出后就好了。《内经》说：上部有脉搏，下部无脉搏，法当用吐法，如果不吐则会死亡。
有的人形体肥胖，平时喜欢饮酒，忽然舌根强硬，语言不清，口眼歪斜，痰气上涌，肢体不能随意运动，这是肥胖之人容易患中气病，因为外表丰盛而内部亏虚，加上饮酒产生的湿热，病症就形成了。必须使用六君子汤，加入煨葛根、神曲，多用人参来挽回元气，所以元戎说：酒湿之病，也能造成痹症，出现口眼歪斜、半身不遂、舌强不正，完全像中风，应当泻除湿毒，不可当作风病治疗而使用发汗法。
卢砥镜说：《内经》讲，神志因思虑过度而受伤，肌肉就会消瘦脱失；意念因忧愁过度而受伤，四肢就会废用；魂因悲哀过度而受伤，筋脉就会挛缩；魄因喜乐过度而受伤，皮肤就会干枯；志因盛怒过度而受伤，腰脊就难以俯仰。过去有一位寡妇，十指拳曲挛缩，手掌沉重无法举起，肌肤疮疡斑驳，服用各种祛风药物无效，后来用舒解郁结、调和气血的方法而痊愈。
有一个久病痢疾的人忽然昏倒，眼睛向上视，脉搏杂乱无章，冷汗大泄，丹溪先生说：这是阴虚而阳气突然断绝。这是由于病后饮酒且房事内伤所致，急需治疗人参膏并灸气海穴，一会儿手部能动。又过了一会儿嘴唇动，服下三剂人参膏后苏醒，服完几斤人参膏后痊愈。凡是大病之后，以及妇女产后，多有这种症状。丹田气海与肾脉相通，人刚出生时，先天的命门之气，胞系在肚脐，所以气海、丹田，实际上是生气之源，十二经脉的根本，所以艾灸有效。
Mouth and eye deviation (facial paralysis) is caused by disease in the blood vessels, distinguished between tendon diseases and vessel diseases, mostly related to the Stomach Earth. The *Classic* states: When the tendons of the Foot-Yangming and Hand-Taiyang meridians are tense, the eyes become deviated and cannot look straight ahead; this is a tendon disease of the Stomach causing mouth and eye deviation. It also states: The meridian of the Foot-Yangming runs alongside the mouth and circles the lips; this is a vessel disease of the Stomach causing mouth and eye deviation. Because the mouth and eyes move frequently, wind is generated; because the nose and ears remain still, wind subsides. However, tendons are nourished by blood, and vessels are the residence of blood. The *Classic* says: If vessels do not provide nourishment, tendons become tense. Furthermore, when pathogens invade due to deficiency, if one is struck by cold, tendons contract and pull the cheek, causing mouth and eye deviation; if struck by wind-heat, tendons and vessels become flaccid or dry and contracted, all leading to deviation. Yet, if Qi and Blood are healthy, heat does not necessarily cause flaccidity, nor cold necessarily cause tension. The presence of cold or heat is mostly due to the deficiency of Qi and Blood. Therefore, one should not assume that deviation to the left implies cold on the left and heat on the right, or vice versa for the right side. Wherever there is tension, there is a deficiency of Qi and Blood. In summary, cold is a pathogenic factor, while heat relates to Qi dysfunction. Areas where Qi fails to reach become sites of cold and disease. Can it be that one meridian is simultaneously attacked by both cold and heat pathogens, or one disease presents with both cold and heat Qi natures? Understanding this, we see that although various diseases may afflict one person with mixed symptoms, their root principle lies in unity (deficiency).
The *Ling Shu* states: Regarding the tendons of the Foot-Yangming, cold in the cheek tendons causes contraction and pulling, while heat causes flaccidity. Thus, cold on the left and heat on the right leads to left-side tension and right-side flaccidity; heat on the left and cold on the right leads to right-side tension and left-side flaccidity, due to the failure of Yang Qi to circulate freely. The *Classic* says: Where pathogens gather, Qi must be deficient. Hemiplegia or facial deviation, whether on the left or right, results from uneven circulation of blood vessels and unbalanced Qi. Treatment should focus on tonifying righteous Qi, moving stagnant Qi, and dispersing wind Qi, so that when Qi is balanced, wind subsides.
Wang Jiezhai said: After excessive eating and drinking, if one contracts wind-cold or suffers emotional anger, food stagnates in the Taiyin Spleen, preventing Stomach Qi from descending. Suddenly, reversal occurs, leading to coma and unconsciousness, termed Food Reversal (*Shi Jue*). If mistakenly treated as Wind Stroke or Qi Stagnation, death will ensue immediately. One should only use Yin-Yang light salt soup to induce vomiting; once the food is expelled, recovery follows. The *Classic* states: If there is a pulse above but none below, vomiting is indicated; failure to vomit leads to death.
Some individuals who are obese and habitually drink alcohol may suddenly experience stiffness of the tongue base, slurred speech, mouth and eye deviation, surging phlegm-Qi, and limb immobility. This is typical of Qi Stroke in obese people, characterized by external abundance but internal deficiency, compounded by damp-heat from alcohol. Treatment requires Liu Jun Zi Tang (Six Gentlemen Decoction) added with calcined Ge Gen (Kudzu Root) and Shen Qu (Medicated Leaven), using large doses of Ren Shen (Ginseng) to rescue the Qi. Yuan Rong stated: Diseases of wine-dampness can also manifest as Bi Syndrome, presenting with mouth and eye deviation, hemiplegia, and stiff tongue, resembling Wind Stroke. One must drain damp-toxicity and must not treat it as a Wind Disease requiring sweating.
Lu Dijing said: The *Classic* teaches: Spirit damaged by overthinking leads to muscle wasting; Intent damaged by sorrow leads to limb disability; Soul damaged by grief leads to tendon spasms; Corporeal Soul damaged by excessive joy leads to dry skin; Will damaged by rage leads to difficulty bending and stretching the waist and spine. Once, a widow suffered from curled fingers and heavy palms unable to lift, with mottled skin lesions. Various wind-dispelling herbs failed. She was cured by soothing depression and regulating Qi and Blood.
A patient with chronic dysentery suddenly fainted, eyes rolling upward, pulse chaotic, and profuse sweating. Danxi said: This is Yin deficiency with sudden collapse of Yang. It resulted from sexual activity after illness. Urgently treat with Ren Shen Gao (Ginseng Paste) and moxa the Qi Hai (Sea of Qi) acupoint. Soon, hand movement returned. Then lip movement returned. After three doses of Ginseng Paste, consciousness returned; after consuming several jin, full recovery occurred. Such symptoms are common after severe illness or postpartum in women. The Dantian and Qi Hai connect with the Kidney Meridian. At birth, the Life Gate (Ming Men) is established first, and the uterus connects to the umbilicus. Thus, Qi Hai and Dantian are truly the source of generating Qi and the root of the Twelve Meridians, which explains why moxibustion is effective.
