This is amazing for kids ear infections and pink eye! This year we had so many family members that were sick with the cold and flu. My two youngest daughter's got ear infections and pink eye at the same time. I wish I knew about colloidal silver when they were babies. It would have saved my daughters from all the homeopathic things I've tried to do for ear infections that failed. I have not seen anything....and I mean anything work as fast as this colloidal silver spray. I sprayed 1 pump in both my daughters ears and the infection was gone by the next day. I also sprayed this in their eyes when they had pink eye. The pink eye took a little longer to cure, but I used it 2-3 times. A day for about 3 days and the pink eye was cured. I pray that I'm never without this product. I think it is so convenient to have it in a spray bottle.
