Silver in the yarn is highly germicidal, quite harmless to humans and absolutely non-toxic. Rather than in a chemical compound, all virus, fungus, bacterium, streptococcus, staphylococcus, and other pathogenic organisms are killed in three or four minutes upon contact. There are no side affects whatsoever from the melting concentrations.
