As the Chinese medical adage goes, “The spleen and stomach are the foundation of postnatal life and the source from which qi and blood are produced.” When the spleen and stomach are strong, the essence of food and drink can be transformed and transported, nourishing the organs and filling the body with vital energy. When they are weak, mild symptoms include poor appetite, abdominal bloating, fatigue, and loose stools. In more severe cases, the body cannot produce enough qi and blood, and all manner of illnesses can arise.
