"Without the ability to achieve -50mV and the necessary raw materials to make new cells you cannot maintain your health, and you will suffer aging and chronic disease. You also are unable to repair injuries, so they can also lead to chronic disease. You don't need drugs to heal. You need to make new cells that work to heal. To make good cells you need voltage and a good diet. You also need to remove toxins from your body that damage cells and make you obese. "
