History of Use
Before the invention of antibacterial soap, colloidal silver was used and as a disinfectant. It is still most commonly used to kill bacteria. Silver is effective at both preventing and combating bacterial illnesses and infections because it does not corrode. In ancient times silver was used in wound dressings and it was frequently used for the same purposes in America following the Civil War. Before the invention of the refrigerator, it was common practice to drop a silver coin into a container of milk as a preservative because silver was known to prevent the growth of algae, bacteria and other undesirable organisms. Dating back to ancient times, silver was also a popular remedy to stop the spread of diseases. Its use as a natural antibiotic continued all the way until the 1940s, when modern antibiotics arrived, but has become popular again along with lifestyle trends that promote natural organic food.
