it is true about labs coming back with negative parasites results. i worked at facility, and one of my patients had a 6 inch brownish worm come out of his bladder and into his foley catheter. i collected it and sent it to the lab, but the results came back negative. all of the staff was astonished because we all know it was a parasite. at any rate, i have found wonderful results with diatomaceous earth, and now have been hearing about mms or Black-Walnut hull. does anyone have any recomendations?
