Kills 99.94 per cent of enveloped viruses
Oral Science International (OSI) announced that COLD & FLU GUARD, a spray that forms a protective barrier in the mouth and nose, killed 99.94 per cent of enveloped viruses in a test by Microbiological Solutions Limited (MSL) UK using a validated methodology for the medical area.
COLD & FLU GUARD is a medical device, available as an oral and nasal spray in Canada and Europe, that forms a protective barrier against multiple pathogens. It contains a patented bioflavonoids formulation made of citrus extract called Flavobac. Studies conducted by independent laboratories have demonstrated the efficacy of Flavobac against the most common strains of respiratory viruses.
COLD & FLU GUARD is designed to be applied directly in the most common route of respiratory viral infection, the mouth and the nose.
“In this in-vitro study by MSL UK, COLD & FLU GUARD killed 99.94 per cent of the tested enveloped virus in <5 minutes. This new data reinforces previous antiviral studies which showed that Flavobac, a key ingredient of COLD & FLU GUARD kills human coronavirus, influenza virus, rhinovirus and the RSV, including the most difficult strains of cold and flu virus such as H5N1 (bird flu), H1N1 (swine flu), and SARS-CoV”, said Dr. Michael Glogauer, chief science officer of Oral Science International.
“These new data reinforces that COLD & FLU GUARD quickly kills enveloped viruses, making it an effective and convenient option to protect against pathogens that enter through the mouth and nose”, said Christian Sauvageau, president of Oral Science International. “We firmly believe that COLD & FLU GUARD will demonstrate the same efficacy against all cold and flu viruses, including SARS-CoV-2.”
