Abstract: A field-effect harmonizer for biosystems and substances with a wide application range in a plurality of shapes and sizes from packaging for perfumery products, water, foodstuffs, alcoholic products, and medications to chambers and facilities for healthcare and biotechnology problem solving. The invention generates fields with a positive impact on living organisms including human bodies and on substances, comprising a disc with 23.5 or more GB of G. Vorsunov's biologically active films (BAF) or a disc with film plates affixed thereof, obtained from the discs that had been recorded with BAF, or from several such plates compiled in stacks, or from other data carriers storing information in a quality fashion and in an amount sufficient for launching positive changes in biosystems, located on any surface covered with a light-reflecting material made of aluminum foil, mirror, or polished metal, etc., to reflect the field to the biosystem.
