《伤寒论·辨阳明病脉证并治法》
脉沉主里，可知其病在里，却反而用发汗法治疗，汗出津液外泄，津伤肠燥成实，所以大便硬结难以解出。津液外越而虚，津伤肠燥成实，时间一长，就会发生谵语。
沉为在里，而反发其汗，津液越出，大便为难，表虚里实，久则谵语。
Deep pulse means the disease is inside, but instead it is treated with diaphoresis. Sweat and body fluid are lost, body fluid damages the intestines and dryness becomes serious, so the stool is hard and difficult to pass. Body fluid becomes more and more empty, body fluid damages the intestines and causes dryness, and gibberish occurs after a long time.
