《黄帝内经·灵枢·禁服》
除以上情况，还必须审察疾病的整个过程，辨明疾病寒热，以辨别五脏六腑的具体病变。
必审按其本末，察其寒热，以验其脏腑之病。
In addition to the above situations, it is also necessary to examine the entire course of the illness, to distinguish between coldness and heat in the illness, to distinguish the specific illnesses of the five internal organs and six viscera.
