Magnesium Chloride

  "There is a power and a force in magnesium that cannot be equaled anywhere else in the world of medicine. There is no substitute for magnesium in human physiology; nothing comes even close to it in terms of its effect on overall cell physiology. Without sufficient magnesium, the body accumulates toxins and acid residues, degenerates rapidly, and ages prematurely. It goes against a gale wind of medical science to ignore magnesium chloride used transdermally ( in the treatment of any chronic or acute disorder, especially cancer.
