My husband, my 3 sons and myself have been using collidal silver for over 10 years. We have used it successfully to treat and cure all of the following; planters warts, acne, sore throats, eye infections, burns, skin infections, sinus nfections, and the flu. I am happy to report, that none of us have turned "blue". The only side effect that I can say we have experienced is "good health". Thank You Utopia for providing a product that works and a company we can trust!
