Onion may hold the key to beating hay fever, says a new study.
Dutch researchers say onion skins contain quercetin, a potent natural anti-histamine and anti-inflammatory shown to help hay fever sufferers.
According to the British Onion Producers' Association, onions contain three times as much quercetin as kale - the next-richest source - and 10 times as much as broccoli, reports The Daily Express.
Allergic rhinitis triggered by the pollens of specific seasonal plants is commonly known as "hay fever", because it is most prevalent during haying season.
Although hay fever can not spread from person to person the symptoms can pass from person to person and it is the biggest cause of sickleave in the US and the UK.
