London: Researchers have found a possible cure of hay fever that is plagued by itchy eyes and a runny nose in summer. The sufferers may find relief in a powder produced from pine trees.
The cellulose nasal spray forms a barrier over the membrane, lining the nose and filtering out allergens like tree and flower pollen.
Scientists at the University of Gothenburg in Sweden said they have proven that the spray does reduce symptoms of hay fever, otherwise known as seasonal allergic rhinitis, especially among children.
“The cellulose powder has no adverse effects, and this fact makes it a particularly attractive treatment for children,” a newspaper quoted associate professor Nils Aberg, as saying.
“It is used increasingly in many countries, but there is until now no scientific study proving the efficacy of the cellulose powder in children during the pollen season,” added Aberg.
The research was carried out at Queen Silvia Children``s Hospital in Gothenburg during the birch pollen season in spring 2009.
The study was published in the journal Pediatric Allergy and Immunology.
