经曰∶风为百病之长，清净则肉腠闭拒，虽有大风苛毒，弗之能害。否则天有八风，乘
虚感袭。又曰∶贼风虚邪，避之有时。贼风者，如立春日起，肝木王七十二日，西风为贼邪，金克木也；立夏
日起，心火王七十二日，北风为贼邪，水克火也；立秋日起，肺金王七十二日，南风为贼邪，火克金也；立
冬日起，肾水王七十二日，西南风为贼邪，土克水也；三、六、九、十二月，脾土每季王一十八日，东风为贼
邪，木克土也。此对冲之风，最能伤人，然中气足，腠理密者，始能无害。其所以受邪致病者皆怯弱之体，故
风邪得以乘之。或有不慎而感受者，顿然头痛鼻塞，呵欠喘急，身热脉浮者是也。盖肺主皮毛，风入皮毛，多
为咳嗽，其指纹红紫而长，外感候也。复有伤风自利，腹胀而手足冷者，脾怯也，当与和脾而兼发散。有潮热
多睡，气粗呕吐，乳食不消，大便黄白而嗽者，脾肺受寒，不能受纳而吐也。若伤风多泪，胁痛目肿而咳者，
兼肝证也；舌苦面赤，汗流而嗽者，兼心证也；面黄唇肿，少食恶心，兼脾证也；面白眶肿，上气喘急，为肺
本病也；嗽而腰疼者，兼肾证也。

《黄帝内经》说：风是引发各种疾病的先导，如果人体保持清净状态，肌肉纹理和腠理就会闭合抵御外邪，即使遇到猛烈的大风和剧毒，也不能伤害人体。如果不注意保养，自然界八方之风就会趁着人体虚弱之际侵袭机体。又说：贼风虚邪，应当根据时节加以躲避。所谓贼风，是指在立春之后，肝木当令的七十二天内，西风成为贼邪，因为金克木；在立夏之后，心火当令的七十二天内，北风成为贼邪，因为水克火；在立秋之后，肺金当令的七十二天内，南风成为贼邪，因为火克金；在立冬之后，肾水当令的七十二天内，西南风成为贼邪，因为土克水；在农历三、六、九、十二月，脾土在每个季节的最后十八天当令，此时东风成为贼邪，因为木克土。这种对冲的风，最能伤害人体，但如果中气充足、腠理致密的人，才能免受其害。之所以受到邪气致病，都是因为体质怯弱之人，所以风邪得以乘虚而入。或者有人不慎感受了风邪，突然头痛鼻塞，打哈欠，呼吸急促，身体发热，脉象浮数，这就是伤风的表现。因为肺主皮毛，风邪侵入皮毛，多引起咳嗽，小儿指纹红紫且长，这是外感证的征象。又有伤风导致腹泻，腹胀且手足发冷的，这是脾气虚弱，应当用调和脾胃兼以发散风邪的方法治疗。有出现潮热、嗜睡、气粗呕吐、乳食不消化，大便黄白相间并伴有咳嗽的，这是脾肺受寒，不能受纳食物而导致的呕吐。如果伤风后流泪多，胁痛目肿并咳嗽的，是兼有肝证；舌苔苦、面色赤红、出汗并咳嗽的，是兼有心证；面色发黄、嘴唇肿胀、食欲减退、恶心的，是兼有脾证；面色苍白、眼眶肿胀、上气喘急的，是肺的本病；咳嗽且腰痛的，是兼有肾证。

The *Yellow Emperor's Inner Canon* states: Wind is the leader of all diseases. If one maintains purity and stillness, the flesh and pores will close and resist, so that even strong winds and severe toxins cannot cause harm. Otherwise, the eight winds of heaven will invade while taking advantage of deficiency. It is also said: One should avoid thief wind and empty evil at appropriate times. "Thief wind" refers to specific seasonal winds that become pathogenic due to the five-element overcoming relationship: during the seventy-two days after the Beginning of Spring when Liver Wood is dominant, the West Wind becomes a thief evil because Metal overcomes Wood; during the seventy-two days after the Beginning of Summer when Heart Fire is dominant, the North Wind becomes a thief evil because Water overcomes Fire; during the seventy-two days after the Beginning of Autumn when Lung Metal is dominant, the South Wind becomes a thief evil because Fire overcomes Metal; during the seventy-two days after the Beginning of Winter when Kidney Water is dominant, the Southwest Wind becomes a thief evil because Earth overcomes Water; in the third, sixth, ninth, and twelfth lunar months, Spleen Earth is dominant for eighteen days each season, and the East Wind becomes a thief evil because Wood overcomes Earth. These opposing winds are most harmful to humans, but those with sufficient Middle Qi and dense pores can remain unharmed. Those who fall ill from these pathogens do so because they have weak constitutions, allowing Wind Evil to take advantage of them. For instance, if one carelessly contracts wind, sudden headache, nasal congestion, yawning, rapid breathing, fever, and a floating pulse may occur. Since the Lung governs the skin and hair, wind invading the skin and hair often causes coughing; in children, a red and purple fingerprint extending long indicates an external contraction syndrome. There are also cases where wind injury leads to spontaneous diarrhea, abdominal distension, and cold hands and feet, indicating Spleen Deficiency; treatment should harmonize the Spleen while dispersing the exterior. Cases presenting with tidal fever, excessive sleepiness, coarse breathing, vomiting, indigestion of milk and food, yellowish-white stools, and coughing indicate Cold affecting the Spleen and Lung, leading to inability to receive and transform, resulting in vomiting. If wind injury is accompanied by excessive tearing, hypochondriac pain, swollen eyes, and coughing, it involves the Liver syndrome; bitter taste, reddish face, sweating, and coughing involve the Heart syndrome; yellowish face, swollen lips, poor appetite, and nausea involve the Spleen syndrome; pale face, swollen eye orbits, upper body asthma, and rapid breathing indicate the primary disease of the Lung; coughing with lower back pain involves the Kidney syndrome.
