The test was only done on 28 people and only 8 showed some improvements. The Improvements where self reported. What I wonder is the statistical error on such a small study. From this small study they are generalising to say that it is "exciting" and "dramatic"!

Usually a small study like this is done as a test of safety and potential benefit as a precursor to a larger more comprehensive study. I think its exciting and dramatic that there were enough initial positive results to move on to a better study.

Also interesting is the fact that the results are in the range that would be expected by the placebo effect.
