You are not the first to wonder that! Back in the early 90s some scientists actually tried it on people with severe AIDS http://www.rci.rutgers.edu/~piecze/Lancet.PDF http://www.rci.rutgers.edu/~piecze/Lancet.PDF - some seemingly improved, but the trial was too small and preliminary to be conclusive. When they published those results, there was a huge backlash about ethical concerns and the research got shut down. I took a class taught by Dr. Pieczenik about 5 years ago and he still believed this idea would work if it was allowed to proceed.
