The manifestations of Grain Jaundice (Gu Dan) include dizziness and palpitations immediately after eating, irritability, restlessness, and subsequent yellowing of the body. This condition arises from overeating after prolonged hunger, causing stomach Qi to rush upward and steam. In cases of Yangming disease (Yangming Syndrome), if the pulse is slow, food intake is difficult, and forced fullness leads to vexation and dizziness, accompanied by difficulty in urination, this indicates an impending development of Grain Jaundice. Even if purgative therapy is applied, abdominal fullness will persist; a slow pulse confirms this diagnosis.
