《黄帝内经·素问·气交变大论》
岐伯说：风是生于东方的，风能使木气旺盛，木气的特性是柔和地散发，它的生化作用是滋生荣盛，它行使的职权是舒展阳气，宣通筋络，它所行时令是风，它的异常变化是发散太过而动荡不宁，它的灾害是摧残散落。
岐伯曰：东方生风，风生木，其德敷和，其化生荣，其政舒启，其令风，其变振发，其灾散落。
Qi Bo said: wind is born in the east, and can make the wood qi prosperous, and the nature of wood qi is to gently disperse, its biochemical function is to give birth to prosperity, and the authority it exercises is to extend the yang qi and spread the channels and collaterals. The time it governs is wind, its abnormal change is excessive dispersion and agitation, and its disaster is destruction and dispersion.
