《黄帝内经·素问·脉解》
所谓客于孙脉则发生头痛、鼻塞和腹部胀肿的，是由于阳明胃经与太阴脾经之气并行于皮肤肌腠之间，迫于阳明的孙络和太阴的经脉。迫于阳明之孙络，就出现头痛、鼻塞的症状；迫于太阴脾经，就出现腹部肿胀的症状。
所谓客孙脉则头痛、鼻鼽、腹肿者，阳明并于上，上者则其孙络太阴也，故头痛、鼻鼽、腹肿也。
The so-called pain in the head, nasal congestion and abdominal distension when there is a guest in the Sunluo is due to the fact that the qi of the Yangming stomach meridian and the Taiyin spleen meridian run parallel between the skin and muscles, forcing the Yangming's Sunluo and Taiyin's The meridians. Forced by the Sunluo of Yangming, there are symptoms of headache and nasal congestion; forced by the Taiyin spleen meridian, there are symptoms of abdominal distension.
