The best defense against swine flu, or any flu, is the age old remedy of colloidal silver. The metal silve r in its colloidal state can be safely consumed and used in the body. Bacteria and viruses cannot develop resistance to colloidal silver. Silver disables a vital enzyme and mechanism in all bacteria and pathogens so that they cannot survive. It is good to take a few teas poons of colloidal silver daily to maintain health. More coll oidal silver should be taken if experiencing illness.
