Function of bone marrow
Liver governs storing blood, kidney governs clearing blood, and spleen governs producing blood. Bone marrow is the source of hematopoiesis. We are probably composed of 60- 10 trillion cells, and each cell relies on blood to transport nutrients, oxygen and metabolize garbage and waste gas. Chinese medicine says: the eye is treated with blood, the palm is treated with blood, which means treating with blood is enough to treat with blood. No matter how good food is without blood, it can't be delivered to cells, and cells will get sick if they don't get nutrition.
The quality of bone marrow is the key to maintain the normal health index of cells in blood. Solved the problem of human blood source, two typical cases.
