Researchers in Australia are preparing a medical trial to find out if Botox injections could be used as a treatment for asthma.
The landmark experiment will see botulinum toxin type A injected into the vocal cords of 30 asthma sufferers at Monash University in Melbourne.
Medical experts believe the treatment could help patients to breathe easier, as a previous study found many severe asthmatics suffer problems with their voice box as well as their lungs.
"We won't cure asthma, but it may be possible for us to relieve people's symptoms to the extent where their severe asthma turns into a mild or moderate disease," the Monash Medical Centre's Phil Bardin told the Herald Sun.
Asthma, a condition that causes tightness in the chest and shortness of breath, is thought to affect 5.4 million people in the UK.
Botox is most commonly used as an anti-wrinkle treatment, but has been trialled for numerous medical purposes in recent years.
