Jerald Tennant, MD gives me a fascinating lesson in how pH and illness are related to the voltage of our cells. He wrote: Healing is Voltage: The Handbook and Healing is Voltage: Healing Eye Diseases (Dr. Tennant will give a talk on voltage at Natural HealthFest at 1:00. He is also on our 9:00 Keynote Panel.) Then I talk with Alfred Johnson, DO about allergies, food sensitivities and environmental medicine. (He is also on our 9:00 Keynote Panel and giving a talk at 10:30, Hyperbaric Oxygen Treatment-Acute and Chronic Disease).
