On our Science page, there is research by universities, hospitals, and the government showing solid copper kills bacteria and viruses on contact in minutes and suggesting how to stop a cold and other illnesses.
Copper has been used for thousands of years for purifying water and disinfecting wounds, but only recently have scientists figured out ways it may work. A leading theory is that when copper touches a microbe, the high electrical conductance of the copper pops tiny holes in the outer membrane of the microbe cell and kills it quickly.
Researchers have identified over 100 microbial pathogens that are killed by copper, including cold and flu viruses, MRSA, E.coli, C.diff, VRE, and Krebsiella. The CDA said so far no micro-organisms have been found that are not killed or inactivated by copper.
Many hospitals have tested solid copper as a replacement for touch-surfaces such as patient bed rails, tray tables, chair arms, doorknobs, faucets, etc. In the wards tested, hospital-acquired infections have dropped dramatically.
Copper’s effect on cold viruses suggests a new way to stop colds, by rubbing solid copper briefly and gently in the inner nostril where cold viruses tend to multiply before producing full-blown symptoms. Focus group results indicate using StayWell's Copper Germ Stopper is a safe and effective way to stop or prevent a cold long term.
