[52] [77] [81] Silver is not an essential mineral in humans; there is no dietary requirement for silver, and hence, no such thing as a silver "deficiency". [52] There is no evidence that colloidal silver treats or prevents any medical condition, and it can cause serious and potentially irreversible side effects, such as argyria .
Colloidal silver consists of flecks of silver suspended in a viscous liquid known as a colloid, Erin D. Michos, an associate professor of medicine at Johns Hopkins School of Medicine, tells Mic.
Argyria and staining: Ingested silver or silver compounds, including colloidal silver, can cause a condition called argyria, a discoloration of the skin and organs.In 2006, there was a case study of a 17-year-old man, who sustained burns to 30% of his body, and experienced a temporary bluish-grey hue after several days of treatment with ...
Silver is used in some medical appliances because of its anti-microbial nature, which stems from the oligodynamic effect. Chronic ingestion or inhalation of silver preparations (especially colloidal silver) can lead to argyria in the skin and other organs. This is not life-threatening but is considered by most to be cosmetically undesirable.
An equilibrium dispersion of colloidal silver with dissolved silver ions can be used to purify drinking water at sea. [3] Silver is incorporated into medical implants and devices such as catheters . Surfacine ( silver iodide ) is a relatively new antimicrobial for application to surfaces.
Silver nanoparticles (AgNPs) act primarily through a process known as oxidative dissolution, wherein Ag+ ions are released through an oxidative mechanism. AgNPs have potentially vast applications within the fields of medicine, science, and food and drug industries due to their antimicrobial properties, low cytotoxicity in humans, and inexpensive cost.
