The invention relates to a method of increasing organic cell regeneration in a region of a subject. Cellular tissue in the region is subjected to a constant electromagnetic (EM) field of less than 1 mT and having a radiation frequency between 7Hz and 8Hz with an EM field generating device. If the subject region is dehydrated or includes unregulated minerals apt to disturb the resonance of water subjected to the EM field, a resonance medium is located substantially at or adjacent the region, wherein the resonance medium comprises a composition which is adapted to resonate at the frequency of an electromagnetic field. The composition is a biologically active composition containing at least one hyd rated mineral, wherein the mineral is hydrated by regulated water maintained in a constant spatial structure or by regulated water incorporated in a non - destructible matrix. A corresponding system and resonance medium are also disclosed,
