My opinion is to start him on the Hulda Clark book you could purchase is Cure for all disease". It will be a 3wk process. Get the book or go on the web site. I believe it is huldaclark.com. Kids pick up parasites all the time and if he has ever or someone he knew has ever been around animals may have passed them on to him. I've been on Her program for about 1mo and a half and am improving. It will be trying to get him to eat low carb food. Fruits veggies and boiled milk. You have to make sure he keeps eating and keeps his body strong. These things can take over other wise. Boiled milk has much good vitamins and calcium we can absorb. I was allergic to milk but since i boiled it i can tolerate it.
