Electrodermal screen (EDS) ‘is a form of computerized information gathering which is based on physics, not chemistry. A blunt, non-invasive electric probe is placed at specific points on the patient’s hands, face or feet, corresponding to acupuncture points at the beginning or end of energy meridians.
