There was a post asking pretty much the same thing on the Crohn's Disease forum a few months ago. The answer was pretty much a resounding lack of enthusiasm. Put it this way, if there are "multitudes" out there who have been cured by it, they are not rushing here to tell their online friends about it. My guess is - pure guesswork ! - it may provide some symptomatic relief, sometimes. But one sunny day somewhere does not make a drought.
FYI, there is a post on the CD forum, just a few days back, about the FDA shutting down their website, on the basis that its claims are sufficient to make it a drug, and it is not licensed or tested in any way.
