Implications of contaminants to scientific research in homoeopathy

Abstract

Abstract3 sets of potentized hydroalcoholic solutions were analyzed by ultraviolet spectroscopy in order to observe changes due to the dynamization process. For the sets prepared in pharmacies, the spectra from dynamized solutions were different from those of inert solutions; for the set prepared under more rigorous conditions of cleanness, no significant difference could be noted. These results indicate the presence of contaminants in commercial homoeopathic medicines. We discuss the implications of this for scientific research.
