《黄帝内经·素问·风论》
综上所述，风邪是引起各种疾病的首要因素，风邪侵入人体薄弱的地方就会发生变化，能够引起其它各种疾病，风邪致病没有一定常规，但其病因都是因为有风邪的入侵。
故风者，百病之长也，至其变化，乃为他病也，无常方，然致有风气也。
To sum up, wind evil is the leading factor in causing various illnesses; changes occur when wind evil invades vulnerable areas of the human body, which can cause various other diseases; there is no fixed rule for wind evil causing disease, but the cause of the illness is always the invasion of wind evil.
