The relationship between the liver and the spleen involves two aspects, digestion and blood circulation. The liver governs dredging and dispersing and regulates the ascending and descending activities of spleen-qi and stomach-qi, which is beneficial to the transportation and transformation of the spleen. The spleen governs the transportation and transformation of food nutrients that are transformed into blood to nourish the liver, which is beneficial to the dredging and dispersing functions of the liver. If the liver fails to dredge and disperse and invades the spleen, it will cause dysfunction of the spleen, clinically leading to hypochondriac pain, abdominal distension and loose stool, etc.
