WITT and colleagues, Institut fur Sozialmedizin, Epidemiologie und Gesundheitsokonomie, Charite-Universitatsmedizin, Berlin,, have found that high homeopathic potencies are different from potentized solvent.


The aim of the study was to determine whether there is a detectable difference between a high-potency homeopathic remedy and potentized solvent, using REDEM technology.


A REDEM device was used as a black box. In two experiments (3 and 4 replications) stable differences between a potentized 'mother tincture' and potentized solvent were assessed. Statistical analysis was done using ANCOVA.


Significant differences (p < 0.01) between remedy and solvent were found. Where output curves were not near 0, remedy values were higher than controls. 43% ethanol eliminated the effects, and the use of polyethylene containers reduced them.


The REDEM technology requires further investigation to determine the nature of the underlying mechanisms of the observed differences.
