According to German researchers, mouthwashes are supposed to kill coronaviruses in the mouth. But there is one catch: So far, this effect has only been shown in the laboratory.
- German researchers were able to prove in an experiment that special rinses can deactivate coronaviruses.
- "Gargling" for 30 seconds was enough to extremely reduce the viral load in the oral cavity.

The coronavirus pandemic is not over, the number of cases continues to rise worldwide. However, there is feverish research into vaccines and medical professionals are making progress in developing new drugs against the coronavirus. Many scientists are concerned with the question of how Sars-CoV-2 can best be combated. German researchers want to intercept the viruses directly at the entry point into the body *: in the mouth.
Corona: prevent infection with commercially available mouthwashes?
German researchers at the University of Duisburg-Essen and the Ruhr University Bochum came to the result in an experiment that some mouthwashes can immensely reduce the corona virus load in the mouth. Eight mouthwashes with different ingredients that are available in drugstores or supermarkets were tested for the experiment. The experiment took place in the laboratory - in the test tube and not in the human mouth. The study directors mixed the mouthwash with a substance that was modeled on human saliva. The researchers had previously prepared these with virus particles. The saliva mixture and the mouthwash were then shaken for 30 seconds in order to achieve a gargle effect .
The result: All mouthwashes tested were able to reduce the viral load. After 30 seconds of gurgling three mouth rinses, the researchers could no longer detect any coronaviruses. "Several formulations with significantly good Sars-CoV-2-inactivating properties that have been proven in the laboratory support the idea that oral rinsing could reduce the viral load in saliva and thus reduce the transmission of Sars-CoV-2, " the researchers said in their Study published in the journal "The Journal of Infectious Diseases". However, the Bochum researchers led by Toni Meister, Stephanie Pfänder and Eike Steinmann point out that this effect has yet to be confirmed in clinical studies on humans.
