Answering my own question to Firekeeper, the latest I can find is that National Institutes of Health lists a total of six double-blind clinical trials on the effectiveness of Reiki for specific conditions*. Three of those trials are recruiting patients, and three are complete. Of the completed trials, I've not figured out how to find results yet, but found positive comments by the principal investigators from two of the trials. I think they're still crunching data, so don't start cheering yet.
Last thread I found on the topic of studies was in 2002, so hopefully this is new news for some folks.
What I find encouraging is that NIH initially funded four studies a couple years ago, then saw fit to fund two more.
Anyone from outside the U.S. want to chime in if their countries are doing controlled studies?
Blessings,
Aronaya
