New Research on Colloidal Silver - A one year long study completed at Harvard and Cambridge Universities shows that CS is effective as an anti-viral, anti-fungal, anti-bacterial and natural antibiotic. This study showed CS to be effective in humans with sinus infections, respiratory infection, bronchitis, strep throat, retro-viral infections, thrush (yeast), ear infections, fungal infections, urinary tract infections, and conjunctivitis. No failures were reported in this study. CS performed better than the five major classes of Antibiotics in killing bacteria. Testing is on-going. http://www.leaflady.org/immune_system_health.htm
