《黄帝内经·素问·诊要经终论》
太阴经脉衰绝的时候，腹胀闭塞，呼吸不利，常欲嗳气，并且呕吐，呕则气上逆，气上逆则面赤，假如气不上逆，又变为上下不通，不通则面色发黑，皮毛枯樵而死了。
太阴终者，腹胀闭，不得息，善噫善呕，呕则逆，逆则面赤，不逆则上下不通，不通则面黑，皮毛焦而终矣。
When the Tai Yin channel declined, the abdomen was swollen and closed, breathing was difficult, belching often, and vomiting. Vomiting, then the qi went up, and the qi went up, and the face was red. If the qi did not go up, it became unconnected up and down. If it was not connected, the complexion was black, and the fur was dead.
