German scientists proved mouthwashes have effect against coronavirus


A team of German scientists has claimed that Sars-Cov-2 viruses can be “inactivated” using commercially available mouthwashes. This was demonstrated in cell culture experiments by virologists from Ruhr-Universität Bochum together with colleagues from Jena, Ulm, Duisburg-Essen, Nuremberg and Bremen. “Gargling with mouthwash cannot inhibit the production of viruses in the cells, but could reduce the viral load in the short term where the greatest potential for infection comes from, namely in the oral cavity and throat,” said study researcher Toni Meister from Ruhr-Universitat Bochum in Germany. All of the tested preparations reduced the initial virus titer, the study said.


Three mouthwashes reduced it to such an extent that no virus could be detected after an exposure time of 30 seconds. However, mouth rinses are not suitable for treating Covid-19 infections or protecting yourself against catching the virus. The Bochum group is examining the possibilities of a clinical study on the efficacy of mouthwashes on Sars-Cov-2 viruses, during which the scientists want to test whether the effect can also be detected in patients and how long it lasts. Clinical studies are in progress.
