Medical reserarchers in Australia are set to use botox to treat severe asthmatics.
Botox is normally used to treat wrinkles, but doctors at Melbourne's Monash Medical Centre hope injections into the voice box will help some asthmatics breathe more easily.
Asthma commonly attacks the lungs but it can also affect the voice box and traditional treatments do not help.
Professor Phil Bardin says the idea is to stop the voice box from cramping, with a selective injection that will paralyse the small muscle.
He says if it can turn patients' asthma from very severe to just mild or moderate, they will have a normal life.
