The World Health Organisation has said there is "no evidence" gargling mouthwash could protect you against coronavirus - despite claims from experts.
A report suggested the liquid could damage the bug's protective membrane and potentially destroy Covid-19 before it infects human cells.
And it prompted scientists to call for "immediate study" to find out more about the impact of mouthwash chemicals in the fight against the deadly virus.
However WHO said: "There is no evidence that using mouthwash will protect you from infection with the new coronavirus." Researchers claim more studies need to be carried out into whether mouthwash may be able to destroy the "envelope" of the virus which stops it from replicating in the mouth and throat.
