The general health-and-vitality promise that placed the device in the period’s market for renewed vigor. The I-ON-A-CO’s advertising was headed ‘New Road to Good Health’ and told readers the appliance would ‘restore the Ionaco user to perfect health,’ explicitly without bathing, dieting, drugging, psychologizing, exercising, faith-curing, or manipulating. This is the disease-free, restored-vitality pitch that the archive treats as a life-extension claim in its dietetic-and-vitalist subset: the device was sold to a lay public as the route to a healthier life through a single passive appliance. Classified testimonial: the supporting evidence was user endorsement assembled for advertising, with no controlled measurement. It is refuted. The device delivered only a weak induced field with no demonstrated physiological effect, no controlled benefit was ever shown, and organized medicine rejected it. Note that the cited sources support a restored-health and renewed-vitality pitch rather than any specific quoted lifespan figure; the longevity reading is the archive’s placement of the case in the vitalist tradition, not an attributed lifespan claim by Wilshire.
