Way before there was Dr. Lee Merritt there was Dr. Hulda Clark. She was way ahead of her time and figured out the parasite/cancer connection before anyone talking about it now. I highly suggest you read a book or two of hers to fully understand the protocols. She used vibrations to kill parasites which was also used by Royal Rife aka The Rife Machine. In regards to using a pre/pro biotic, it will not hurt to use that as well once you have killed off the parasites. You, among most Americans, probably have Leaky Gut as well do to our American diets. Pre & Probiotics can help repair gut flora.
