It was demonstrated (by the MFL method) in experiments the collective dynamical structural states of the liquid medium are the basis of the biological activity of homeopathic preparations (HP). The dynamical structure of water and HP determines the specific structure of the proton potentials in these media and the EM radiation of very low level and uniform spectrum. The vibration structure in medium (specific molecular dynamics, proton potential structure and spectrum of very low level eradiation) have fractal organization--spectrum of processes from high-frequency region (intramolecular vibrations) to low-frequency region (creation and destruction of clatrates) consists of consequence of corresponding regions with the repetition of frequency correlation in every region.
