This work addresses the most puzzling question of Homoeopathy: wherein lies the (clinically undeniable) medicinal value of substances potentised beyond Avogadro limit.It attempts to find the scientific basis of homoeopathy- logically, theoretically and experimentally.First, a theoretical model of induced structure is arrived at as a logical compulsion from a close analysis of properties of water. Then, an analysis is done for a simplified model, which hints at dielectric dispersion spectrum as the likely key to identify potentised substances and finally, an experimental...
