I knew menstruation was important to a woman's health, but I never knew that even without providing nourishment in pregnancy, the blood from our cycles may save lives. Apparently, research is being conducted in India, Japan, and America, scientists have found adult stem cells in menstrual blood. If this blood is banked perhaps it can help people. What a thing that would be for something we would dispose of on sanitary products (which are not biodegradable) would better serve our society. It's a beautiful thing indeed! Women feel empower, you can bring on new life as well as saving lives with your cycles.
