Your comments are in the spirit of common sense. Good to see!
From my experience in practice, I always have to keep in mind that the waste build-up and toxic/parasitic conditions began when the liver develops a sluggish production of bile. A good herbal liver tonic in conjunction with parasitic herbs will work with a 1 week on, 1 week off, 1 week on program. Many people from South America come to me for treatment after contracting intestinal parasites with complete success. It's fun to watch the "miracle" workings of herbs and the body's natural processes.
And as already mentioned, no need for drastic fastings or extreme diets They only end up weakening the body. We have to remember that you can't starve a parasite by fasting.
