Plant responses to homœopathic remedies

Summary

Over the past 50 years several experiments to demonstrate the biological effects of homœopathic potencies have been devised. All of them have had short-comings: mainly in terms of reproducibility of the method itself and the analysis of the results. This paper describes a simple biological model using the growth responses of wheat coleoptiles to various homœopathic potencies. The results described show that the method is reproducible and that biological activity can be detected at extremely high dilutions. Succussion appears to be an essential part of the preparation of a homœopathic potency. A theoretical basis for this observation is discussed.
