My niece (9 yrs old) got food poisoning eating at a local festival on Friday night. I gave her a teaspoon of colloidal silver 2x and that was it. By Saturday afternoon, she was eating and felt 100% better. "m new to the colloidal silver "thing". I never really believed it would work and now I can't be without it. I advise everyone to get this product. I am 100% satisfied !!!!!!!!!
