evidence: Everything You Need To Know About Edible Silver Foil [...] Yes! Pure edible silver foil was deemed safe for consumption by the European food-safety certification agency, TÜV Rheinland. That said, one has to be sure that the edible silver they obtain is pure. There are plenty of vark products being sold that contain other elements such as copper, aluminum, lead, nickel, and others non-approved metals. Our edible silver foil is made only of 100% pure silver in its inert form so it is absolutely safe to ingest. [...] Edible silver foil is made by pounding non-ionic bioactive pieces of silver into paper-thin sheets. Silver sheets are placed between pages of booklets. The exact materials used in these booklets differ, however. The traditional practice is to use the intestinal lining from a recently slaughtered cow, sheep, or ox because of its elasticity (it won’t puncture when hammered) but other methods are now being used to ensure the silver remains vegetarian. In Indian markets, you might find it pounded between old phone books. Another, more common practice is to use parchment paper.
