Beware your intake of colloidal silver. Once a common ingredient in nosedrops, colloidal silver has been largely discarded due to its disastrous cumulative effect. Large doses administered over a period of time can cause Argyria, an irreversible condition which turns the skin a dead gray. Sufferers resemble walking corpses.
Colloidal silver is still available, mostly as a disinfectant but also amazingly as a dietary supplement, despite the warnings of people such as Rosemary Jacobs, who was prescribed colloidal silver nosedrops at the age of 14 and who still suffers the consequences some 6 decades later.
