This is not my first dance with Silver Sol. I heard of it by accident, but it is a "keeper" in my home and I recommend others keep it too. WHY? It knocks out cold and other germs. I have used it topically on the dog and cat for various skin Abrasions and such. I have dabbed it on paper towels and cotton balls to put lightly on eyes (when they are closed) or in droppers to put tiny bits in eyes for "pink eye". (Disclaimer: I am not a doctor or nurse, but I will try any and everything to help myself and my family. We have found this to be effective, but you try for yourself or ask your own medical professionals.) This is NOT COLLOIDAL SILVER, but SILVER SOL or Hydrosol. This is a great brand, although I have used the American Biotech brand and have that in our cabinet, too. AND PLEASE try the American Biotech brand of Silver Sol gel/lotion/cream. I swear that will probably heal any skin condition
