Are you familiar with the work of Dr. Hulga Clark, Ph.D.? She was a scientist and pioneer of revolutionary cancer research and treatment. She invented a device that was able to detect many substances that precipitate tumor formation, including chlorine, propylene glycol, isopropyl alcohol, parasites, and even mold. Her books are a little tough to take on because they are overwhelming in terms of the number of things to avoid and the lengths one must go to in order to treat food (such as with heat and vitamin C powder) to make it safe for cancer patients. But her son started a great store, drclarkstore.com, with excellent, pure products up to Dr. Clark’s standards. I love the Foodie’s Best Friend digestive enzymes https://drclarkstore.com/foodies-best-friend-digestive-enzyme-formula-500-mg-60-tapioca-capsules/, the Pearl Olive Oil Soap https://drclarkstore.com/pearl-olive-oil-soap-130-gm/, and use the Pure and Natural Shampoo https://drclarkstore.com/pure-natural-shampoo-16-oz/ for my child. She also has amazing water filters https://drclarkstore.com/searchresults.html?keywords=filter that are definitely worth a look.
