When the Blood is plentiful and nourished, the body is healthy! Digestion, immunity, and mental function are strong. When you eat to nourish the Blood, you're eating to please the functioning of the Spleen system. In Chinese medicine, the Stomach and Spleen are the root of our health, in western terms it is like saying that everything starts in our gut. The better our digestion, the stronger and better the flow of our Blood and energy (Qi) are.
