A method and a system are provided for subjecting organic cells in a region of a subject to an extremely low frequence magnetic field. At least one resonance medium is operably connected to a generator. The generator produces a sinusoidal non-harmonic current signal, having a predetermined frequency of substantially between 7.5Hz and 7.9Hz and a electromagnetic radiation of substantially between 0.7mT and 3mT. The resonance medium is energised by the signal and located adjacent organic cellular tissue in the region for a predetermined period, whereby organic cells in the region are subjected to a constant magnetic field of less than 1 mT and having a frequency of substantially between 7.5Hz and 7.9Hz for the predetermined period.
