Mouthwash could potentially be used to fight coronavirus, according to a new study.
A non-peer-reviewed study from Cardiff University showed "promising signs" that mouthwashes containing at least 0.07% cetypyridinium chloride (CPC) were able to kill the coronavirus.
In the study, scientists mimicked the environment of a person's naso/oropharynx passage and used various mouthwash brands.
The study supports similar research published last week.
Dr. Nick Claydon, a specialist periodontologist, said he believed the research was "very valuable."
"If these positive results are reflected in Cardiff University's clinical trial, CPC-based mouthwashes such as Dentyl used in the in-vitro study could become an important addition to people's routine, together with hand washing, physical distancing, and wearing masks, both now and in the future."
