As Waterman says, the colloidal silver knocks off the pathogens on contact. A tablespoonful can be gargled then swallowed after exposure to a crowd or at first sign of sore throat or cough. Or a spray bottle is handy for a whiff into the mouth,might be good idea for young child, and maybe into nose. I've sprayed into eyes at a hint of an infection, and a few drops in the ear is a great remedy for swimmer's ear. And, quite off topic, I use spray one for a deodorant. Aloha, bushycat
