Treatments claiming to detect, channel, balance or apply an unmeasured life force, magnetic fluid, electromagnetic field, color or light in order to heal, rather than a manual technique, water, a compounded remedy or a cutting operation. This includes the historical magnetic-fluid tradition (animal magnetism, mesmerism) and its device-based descendants (Perkins Patent Tractors, faradic battery, galvanism (medical), electrotherapeutics, electrohomeopathy), modern energy-field and life-force practices (reiki, energy medicine, crystal healing, bioresonance therapy), light- and color-based claims (chromotherapy, blood irradiation therapy), and device-based field or radiation claims (magnet therapy, radionics). A treatment whose defining agent is water immersion, direct manual pressure or manipulation, or an ingested or applied compound, even when marketed with energy-related language, is grouped elsewhere.
