《黄帝内经·素问·逆调论》
营气虚弱则皮肉麻木不仁，卫气虚弱就会出现肢体不能举动，如果营气、卫气都虚弱，就会出现皮肉既麻木不仁又不能举动沉重。
荣气虚则不仁，卫气虚则不用，荣卫俱虚，则不仁且不用，肉如故也。
If Qi is deficient, the flesh will be numb and unconscious, and if Weiqi is deficient, limbs will not be able to move. If both Qi and Weiqi are deficient, the flesh will be numb and unconscious, but also unable to move heavily.
