Silver is a natural element that can be found in whole grains, edible and medicinal mushrooms, mammalian milk, spring water, sea water and tap water. Used medicinally for more than 2,000 years, silver has played an integral role in safeguarding human health. 

Silver is well known to be a broad spectrum antimicrobial agent, but has also been reported that is has anti-viral, anti-inflammation, anti-biofilm activities and enhanced wound healing.  Some studies suggest that the particle size, shape, surface charge, surface coating, solution chemistry, and solubility affect silver’s toxicity.
