I can vouch on personal experience this shite works. If I get just a hint of a sore throat that always seems to precede a cold, I load up on the silver, the echinacea, zinc and oil of oregano (which will put you on the rag, though I don't think I do that anymore), and I don't catch the cold if I get to it in time.
