Todd, we tried the zeolite with my father with no positive results. I wouldn’t waste my money. I would suggest, however, you contact the Centre for Natural Healing in Oregon. (http://www.centrehealing.com) They came very highly recommended to me by a friend in the natural healing world because they have a good track record with cancer patients. We’ve had two consults with Jonathan Treasure, and he’s been a really good resource. My Dad can’t (or won’t) swallow capsules so we can’t totally follow their prescribed protocol, but we are doing some of it. Tell him Julie Wright sent you if you call….good luck to you!
