To support mountains of anecdotal evidence, there have been an increasing number of clinical trials to validate and quantify the benefits of Reiki. Below is a very partial list, to give you an idea of how this work is being approached and by whom. Due to copyright considerations, I cannot give you access to all these studies, but I’ve provided links to further information when possible.

It is abundantly clear that more, quality research is needed, and I’m working towards that goal as quickly as possible via several avenues. If you know any researchers or students of medicine or mental health looking for an incredible opportunity, please have them get in touch. I am fortunate to have a number of enthusiastic colleagues eager to shed more light on this subject for members of the medical community who are still in doubt.
