Mouthwash 'Chlorhexidine' can kill coronavirus, says a Punjab University study

It must be mentioned that Chlorhexidine gluconate is a germicidal mouthwash that reduces bacteria in the mouth.

The study, titled "Chlorhexidine: An effective anti-Covid mouth rinse" was supported by Hyderabad Headquartered Dr. Reddy's Laboratories and Design Innovation Centre, Punjab University.

Studies have shown that the Covid-19 virus colonizes in the oral and nasal cavities. Mouth rinses can be an efficient way to reduce colonization and possibly reduce the spread of infection.

However, the study is in the preprint server and yet to be peer-reviewed.

" We found that a mouth rinse with the required concentration of Chlorhexidine killed coronavirus within 30 seconds after being exposed in a laboratory. In our current study, we used only Chlorhexidine. However, it is to be seen whether a commercial mouth wash is as effective as was found in the study because of the other ingredients found in a mouth wash. the initial results from the lab studies and need to be verified through clinical studies. " stated Dr. Ashish Jain from Dr. HSJ Institute of Dental Science and Hospital.
