Hi twogirlsdad,
Maybe you should turn your question around and ask yourself, why are you taking anecdotal evidence as your gold standard? Personal stories 1) don't tell you what the overall success rates are (an individual anecdote may be wildly unrepresentative), and 2) they rely on subjective impressions of success rather than measured improvements.
There's also a burden-of-proof issue here. Proposed therapies basically need to be assumed ineffective until proven otherwise. The fact that this therapy has not managed to generate a shred of research in its favor is a very bad sign.
