To the original poster: You probably know this already, but the best evidence is taken from published peer-reviewed double-blind, placebo-controlled studies, also known as Randomized Clinical Trials (RCT). The worst evidence, as you know, is anecdotal. Either there are published studies or not. If there are not, then move on. Many people here don't wait for published clinical studies because they are very anxious to become well again. That's a personal choice. Ask the website owner if they have any published RCTs, then make your decision. Best of luck to you.
