I think this is one of the finest and most trusted companies around. I've read that Dr. Clark thinks they are a good company as well as MH. Their herbs are of highest quality and their knowledge is gold. I did the Bowel Cleanse kit and was really happy with the results. I would only imagine their full kit is as good as the kit I did. I can't afford that much money right now.. but I hope to do it in the future.
