Results of a clinical trial were completed in December 2015 for Gulf War illness to study an "innovative detoxification program." The trial is described at the US NIH clinical trial study website.
What was the test program? It was the Hubbard Detoxification Method, developed by the founder of Scientology, L. Ron Hubbard. It's also used by the Church of Scientology as an introductory service, and believed by Scientologists to be the only way to deal with the long-term effects of "toxic exposure."
