Some info:
The modern era of silver began in 1893 when C.Vion nageli reported the first systematic investigation into the lethal effects of metals (especially silver) towards bacteria and lower life forms. From 1900 to the beginning of the antibiotic era-circa 1940- silver was one of the mainstays of medical practice in europe and america. colliodal silver became the choice of medical practitioners and was used to treat literally hundreds of ailments, including lung infections such as pneumonia, TB, pleurisy, gonorrea, syphilis, cuts, leg ulcers, eczema, impetigo,typhoid, tonsilitus, and many more.

however, with the coming of the antobiotic era and because colloidal silver became increasingly expensive to manufacture, it fell to disuse- it being replaced by first sulfur drugs, then penicillin and since then by hundreds of specialised antibiotics (which drug companies made millions from because they could patent the drug but not the use of silver) under the onslaught of antibiotic warfare,the second half of the 20th century witnessed the seeming eradication, or at least control, of most of mankinds ancient plague scouges.
yet by the 1990s the picture began to change! this is because more and more germ species previously controlled by antibiotics began to develop ways to combat antibiotics. This in turn gave rise to so called super germs, such as killer E. coli, flesh eating Strep a bacteria, multiple antibiotic resistant TB bacteria and chloroguine-resistant malarial parasites. Fortunatly, the timely re-emergence of colloidal silver due to new technology and much reduced costs in production, may prove to be one of the best remedies we have to protect ourselves.
It kills MRSA and Anthrax also.
My mum had a bad infection in her jaw recently, even after the dentist took the tooth out there was pain and swelling, she was given antibiotics, (2 lots) but it was no good.
She took colloidal silver as instructed on the bottle and is now pain free and no swelling.
