Another word for the EPFX is energetic medicine. The EPFX is not to be used as a diagnostic tool because the results from the test, that appear in the test matrix, are based on an interpretation of your energy. The EPFX is used for stress reduction. Why stress reduction? Because stress is what causes physical problems. The EPFX has been designed as a stress reduction and pain management system because the inventor, Professor Bill Nelson, understands the innate intelligence of the human body. The human body has the complete potential to heal itself.
