Researchers at Cardiff University have been investigating the impact of chemicals found in common mouthwashes in the fight against coronavirus – with encouraging results
Mouthwash could be a key tool in the battle against the coronavirus, according to new research.
Professor Valerie O’Donnell is co-director of the Systems Immunity Research Institute at Cardiff University, and has been researching the power of mouthwash to help fight the disease.
Cetylpyridinium chloride – a key ingredient in many types of mouthwash – has been studied by scientists to uncover the effectiveness in helping stop the spread of coronavirus.
The chemical has raised hopes due to the “virucidal effect” that it has to kill 99.9% of pathogens and bacteria in the mouth.
Professor O’Donnell told The Daily Telegraph: “Our view is that the in vitro studies (including this one and also two other recent studies which showed the same for Listerine and PVP-I) are highly encouraging but so far, in vivo studies have not been published.
“The human oropharynx will be constantly producing virus so we don’t know how long the effect would persist for – this is the main question.
“Recent studies in test tubes have as much as possible tried to mimic the conditions in the throat, but of course this isn’t the same as in vivo.”
