Elecrodermal screening uses an electronic probe to measure the electrical resistance at numerous points on the body (primarily the hands and feet). This technology is not an instrument used to diagnose disease. It does however measure the electrical current moving through the acupuncture meridians and as such gives information about the bioenergetics of the body. An EAV machine is an instrument of physics not chemistry and as a result is not recognised by mainstream medicine.
In the 1950’s Dr Voll, a German doctor, observed that traditional acupuncture points had a lower electrical resistance than other skin points. He developed a device to measure the skin’s resistance at these points and found that each point had a standard measurement for all healthy people. He concluded that increases from this normal reading meant there was tissue inflammation associated with that point. Decreases from the normal reading indicated that there as fatigue or tissue degeneration associated with that point.
During an EAV test no formal diagnosis will be made, nor prescription drugs prescribed but the practitioner will offer an assessment of your general state and may make recommendations for dietary or lifestyle changes, nutritional, herbal or homeopathic supplements.
