Do people have any experience or knowledge around parasites? Do you recommend a precautionary parasite removal on a regular basis. The amish Do it every 6 months. A friend of mine had gall stones and the doctor said the gall bladder has to go. He did some research and found it can be related to parasites. Took some magic anti parasitic (wasn't cheap, about 200 bucks so far) and had hundreds of parasites exiting via the ass over a couple of weeks. Largest was 8 inches. Many more were smaller. Makes me want to take an anti parasitic just to be safe.
