Apparatus for inducing electrically charged alignment changes in biological tissue includes a generally flat translucent cavity containing a volume of gas that includes water vapor, carbon dioxide and other similarly common molecules that is charged along one surface by a sequence of pulses of electrical charge each of a potential sufficient to excite the common molecules to a higher state. The opposite side of the cavity is then conformed for intimate contact with the skin of a person, thus communicating the right hand spin electromagnetic pulses associated with each excitation level change into the tissue. A pulsed coil is then provided in an alignment generally parallel to the plane of the cavity to polarize the clockwise electromagnetic emissions associated with the changes in the excitation states.
