Method for giving a substance (101), particularly water, receptive and/or transmissive properties that allow the substance (101) to be treated by a signal and/or to transmit a signal, particularly a signal acquired by intercepting an electromagnetic field originating from a source substance, comprising the step of subjecting the substance (101), by means of a transmitter (102), to an electromagnetic field and/or a sound (104) emitted at one or more frequencies included in a predetermined frequency spectrum for a predetermined period so that the initially non-receptive and/or non-transmissive substance (101) has receptive and/or transmissive properties.
