How does colloidal silver kill bacteria?
Are there any side effects of using colloidal silver?
Yes, there can be side effects of using colloidal silver, particularly if it is ingested in large quantities. Excessive use of colloidal silver can cause a condition called argyria, which results in a bluish-gray pigmentation of the skin and mucous membranes. It can also cause neurological problems if ingested in very high doses, and may interact with certain medications.
