Before you store listerine, take the findings of a recent study with salt grains – at least until the results come out in a human clinical trial, some experts told Fox News.
In a new study conducted by researchers with the Penn State College of Medicine and recently published in the medical journal Medical Virology, Mountwash and Oral Rinse may “inactivate” the human coronavirus, the authors speculated that these common dental hygiene products may slow down. Can help. The only spread of the novel coronavirus.
“We made it clear that this is not the solution … but the data suggest a strong possibility of low transmission,” lead study author Craig Meyers, a specialty professor of microbiology and immunology and obstetrics and gynecology, told Fox News.
However, the authors of the study did not test the new coronavirus, SARS-CoV-2, while conducting their research, analyzed the human coronavirus – a generic cold-surgeon known as 229e, for SARS-CoV- Is equal to “. 2, the study authors are leading the argument for a comparable argument to the results.
For the study, researchers tested a variety of oral and nasopharyngeal rinses – including a 1% solution of baby shampoo, netty pot, peroxide throat-cleanser, and mouthwash, listerine antiseptic, Oragel antiseptic rinse and Crest Pro – health. Others – to determine how well they deactivated the 229e strain.
Using Mohsin after practice is effective on this blood pressure, the study claims
Human volunteers were not used; 229e coronaviruses were grown in human liver cells in the lab for 30 seconds, one minute and two minutes before immersion in various solutions.
Baby shampoo solution, “used by head and throat doctors to rinse the sinuses.” “After 99 minutes of contact time, more than 99.99% of human coronavirus” inactivated the solution, they said.
Tested mouthwash and oral rinses were also effective, they found: “After 0 seconds of contact time, many people became inactivated by more than 99.99% of the virus and some deactivated the virus after 99 seconds. Is. ”
Leading study author Craig Meyers, a distinguished professor of microbiology and immunology and obstetrics and gynecology, said the results showed that using these common over-the-counter products could reduce the amount of virus (viral load) in an infected person’s mouth. When caring for a minor patient or visiting a dentist, the novelty helps to reduce the spread of the virus in specific cases.
‘Interactive’ by Human Coronavirus Mothwash, Original Rinse: Study
But some experts who were not involved in the study warned that the findings should not be over-interpreted, emphasizing the need for clinical trials to show similar results in humans (in fact, many have started recruiting.)
In addition, while mouthwash can theoretically reduce the viral load in the oral cavity and throat for a short period of time, while dental products cannot prevent the virus from copying into cells inside the body, many experts talking to Fox News noted.
“Professor of Infectious Diseases at the Vandbilt University Medical Center and Medical Director of the National Foundation for Infectious Diseases, Dr. “It’s one thing to show something in the lab, it’s another thing to show something in humans,” said William Schaefner. ”Fox News. “We need data and people first [before] Makes these recommendations among the people. ”
In addition, Schaefner said, “mouthwash does not go back into my throat or under my nose or into my trachea” or some parts of the upper respiratory tract where experts say mimic the novel’s virus. “It can be of little use in understanding,” Scheffner said of rinsing with a mouthwash to reduce the spread of the virus, “but I hope it will be very modest.”

“We know that mouthwashes such as chlorhexidine and listerine can reduce the number of bacteria in the human mouth when used properly (or as suggested, in the case of chlorhexidine). However, we do not know whether it is possible to reduce the number of viruses in a clinical setting, and thus, all types of healthcare providers should continue to do their best, ”such as washing your hands, wearing masks and social distance, Fort News Said Wale Larry Fitzshu, associate professor and interim chairman of the pathology department at Rutgers New Jersey Medical School and Rutgers Robert Wood Johnson Medical School.
“It is important to remember that this study was not on human subjects, but was performed in a test tube; It is difficult to know whether this study is medically relevant and practical, ”she added. “Ideally, you want to see if these people can be reproduced; This has not been done. Also, this was done on a single cell line that is different from SARS-CoV-2, so no one can assume that what human coronavirus has done on the cell line will be just as effective against SARS-CoV-2. “

Dr. John Fischer, Chief Medical Officer of the Health Care Website WebMD. “I know everyone wants to find a cure, but mouthwash is not,” John Woote told Fox News. “COVID-19 is a respiratory virus and not all over-the-counter mouthwash fights the virus in the body. That’s not how they work. ”
Echoing others, Vault also pointed out that the study did not involve humans or that they were studying new viruses.
“There was also rinsing [up to] Two minutes. It’s more time than most people realize or can do in practice, “he noted.
“I don’t want people to think they can rinse their mouths with all kinds of chemicals and then they’ll be safe – because that’s not the case. And we don’t want people to reassure their own mouthwash, possibly hurting.
In an email to Fox News, Meyers, lead author of the Penn State College of Medicine study, said his team “first said that a clinical trial was needed” to prove similar results in people, not just a laboratory. .
“Research doesn’t start with human volunteers, but in the lab. You first need to demonstrate on the lab bench and in the tissue culture cabinet that there is potential for a positive health effect. Once that research foundation is displayed you can try going into human tests. I believe those who are making statements with this kind of final matter are short-sighted that this rinse will not help. “People who lack an understanding of the research process,” he said, noting the fact that clinical trials are working on the subject, “showing that many experts seem to be there. [a] Significant promise. ”

“Does the use of mouthwash eliminate the need to wear masks and social distance, certainly not, but will add another layer to this defense. Are there warnings, yes, but there are potential benefits, yes. All research and tests always have warnings. If everyone sits around and worries about warnings, ignores the available data and possibilities, “he added, his team’s findings also encourage past research into how oral rinses and mouthwashes can be able to reduce the viral load on humans. Were watching. Corona virus. He specifically drew attention to a study outside of Germany that was published in the journal Inf.
“Also, studies suggest that anyone should do anything unusual but do something that is part of normal oral hygiene,” he said. “It was clear to us that this is not a solution … but indicates a strong possibility of reducing data transition.”
