Reiki

So many strange concepts. People need to do some serious, well-funded, widespread research on these things. Most of the research that is done currently is too small scale to prove or disprove anything conclusively. eg:

"There have been reports of positive effects of Reiki treatment in papers published in some medical journals promoting alternative medicine. Proposed benefits include relaxation and increased immunity, reduced heart rate, improved blood pressure, reduced pain, anxiety and depression.[10]. As these results can be attributed to the placebo effect, further studies need to be done to determine the effectiveness of Reiki [11]."

Although, I'd say that the placebo effect was ki related anyway.
