People have long known that silver could be used as a purifying and preserving agent. Ancient Greeks stored water in silver pitchers and early American pioneers would place silver dollars in bottles of milk to prevent spoilage. Even laboratory workers placed dimes in petri dishes to sterilize them. Silver is a catalyst that stops microbes from utilizing enzymes that allow them to metabolize oxygen, literally suffocating the little invaders. This action has made colloidal silver an effective ally in the fight against over 650 disease causing organisms.
Colloidal silver is also an agent that aids in the regrowth of injured tissues.
It has been useful in cases of severe burns and broken bones. Elderly people have noted positive effects on healing. There is also promising research in progress that colloidal silver may be used to help cancer patients. Colloidal silver is considered to be extremely nontoxic and safe for human consumption. It may not be recommended along with intravenous EDTA chelation becauase EDTA absorbs metals from the blood, making colloidal silver useless.
