Pulsed Electromagnetic Field (PEMF) Therapy is the combination of the geomagnetic field of the earth and its frequencies along with the Schumann Resonance of the Ionosphere. They are essential for life…like the food we eat, the water we drink and the air we breathe. Our devices duplicate the earth’s natural PEMF frequencies. #pemf' target='_blank'>http://healthenergies.com/services/#pemf
