《黄帝内经·素问·疟论》
岐伯回答说：疟疾开始发作的时候，先起于毫毛竖立，继而呵欠连连，乃至寒冷发抖而使上下颌止不住撞击，腰背都很疼痛。当寒冷过去之后，接着又是全身内外发热，头痛有如将要破裂，口很渴喜欢喝冷饮。
岐伯对曰：疟之始发也，先起于毫毛，伸欠乃作，寒栗鼓颔，腰脊俱痛；寒去则内外皆热，头痛如破，渴欲冷饮。
Qi Bo answered: When malaria first occurs, it first causes the fine hairs to stand up, then makes people yawn repeatedly, then gives people chills that make their upper and lower jaws uncontrollably knock against each other, and the waist and back will also be aching. When the chills pass, then the whole body from inside to outside will feel feverish, the head will ache as if it will burst, and the patient will have a dry mouth and feel like drinking cold drinks.
