Been down this path for 15 yrs now so researched a lot. I would consider a professional homeopath. These children typically have significant gut issues, so before you start detoxing, you want to be sure their gut/organs are well supported first. I know homeopathic medicine has reversed autism in children, even those who were nonverbal. Many dont realize our original hospitals were all Homeopathic medicine. Real medicine. I use it regularily to treat my family and also our animals. My passion is spreading the good word of this powerful medicine. We moms/dads have to take back control of our childrens health. Clean food is also critical to recovery. God bless all these autistic and sick children. I hope they can all be healed someday soon. ❤️
