The “information / resonance / biofield” family — where words stand in for a coupling model. Some hardware is real (skin-impedance meters, RF generators, reflector geometry), but the doctrines built on it — inverted “pathological frequencies,” “mortal oscillatory rates,” “scalar” and “torsion” fields, “field-information transfer,” passive “information” cards, “structured” water — are unsupported, and several contradict physics or chemistry outright.
