Sapporo Breweries, working with scientists at Sapporo Medical University, claim that a beer ingredient called "humulone" was found to be an effective guard against the RS virus, which can cause severe forms of pneumonia and bronchitis in kids, reports AFP.
Jun Fuchimoto, a researcher from the company, said in a press release: “The RS virus can cause serious pneumonia and breathing difficulties for infants and toddlers, but no vaccination is available at the moment to contain it."
The RS virus spreads in the winter and can also cause cold-like symptoms in adults.
Fuchimoto said such small quantities of humulone were present in beer that someone would have to drink around 30 cans (12 oz) to have any virus-fighting effect.
“We are now studying the feasibility of applying humulone to food or non-alcoholic products. The challenge really is that the bitter taste is going to be difficult for children.”
The research also found that humulone reduced inflammation caused by infection from the RS virus.
