I know through much personal experience that colloidal silver is very effective and safe, and have also read many reports from many others who also find it to be very good as well.

I personally have not had a cold or a flu for several years now ever since I began faithfully using colloidal silver and zinc acetate lozenges. This is remarkable because my exercise program is to surf in the mornings before going in to work - and I go out almost every day, even if there have been rainstorms.

Runoff from the rains causes the ocean to become quite polluted. Many surfers far younger than I will not go in the water for at least 72 hours after the rain; and they frequently suffer from sinus infections.

I have not had a sinus infection for years, which I attribute largely to my use of colloidal silver.
