Botox could offer new hope to the three million Australians debilitated by hayfever every spring.
Australian researchers have discovered that applying a Botox gel to the nasal cavity could provide hayfever sufferers with relief for 90 days.
Professor Philip Bardin, director of sleep and respiratory medicine at Southern Health in Victoria, led a trial that found Botox could be used to block nerve endings in the nasal passage to reduce inflammation and symptoms.
"We've had very promising results using Botox as a treatment for severe asthmatics, and it is possible this new gel could give hay fever sufferers relief from symptoms for an extended period of time," Professor Bardin said.

"Botox is far from a purely cosmetic product. Increasingly we're coming to understand the tremendous clinical benefits that botulinum toxin offers. We hope this world-first trial will be the first step towards relief for millions of Australians and millions worldwide."
Southern Health is now recruiting 70 volunteers to take part in a randomised placebo controlled trial, to confirm the effectiveness of the treatment.
The treatment could replace hayfever tablets and nasal sprays in six to eight months.
