The study was published in the Journal of Medical Virology that included testing oral and nasal rinses’ effect on inactivating the human coronavirus 229e (a strain of coronavirus that causes the common cold)
The baby shampoo solution, “which is often used by head and neck doctors to rinse the sinuses,” the researchers noted in a news release regarding the findings, was particularly effective; the solution inactivated “greater than 99.9% of human coronavirus after a two-minute contact time,” they said.
What about the mouthwash?
Mouthwash is also extremely effective as well.
"Many inactivated greater than 99.9% of virus after only 30 seconds of contact time and some inactivated 99.99% of the virus after 30 seconds.”
They did not test this approach on the novel coronavirus strain also known as COVID-19 but did say the genetic makeup of COVID-19 is genetically similar to the other human coronaviruses they tested and therefore had hypothesized that it could lead to similar results.
At the end of the day, the study led them to believe that an oral rinse can reduce the viral load and can inhibit the production of viruses in the cells.
These are common household items many people already have at home and can begin using to help decrease their chances of falling ill with the virus.
