AN oil discovered in New Zealand mussels by Scots scientists in the 1980s could offer new hope to millions of asthma sufferers.

A study, led by Professor Timothy D Mickleborough at Indiana University, USA, found the oil from mussels reduced dependence on inhalers by 83% and improved the lung function of asthmatics who suffer from exercise-induced attacks by 59%.

The oil, called PCSO-524, was first discovered by Dr Sheila Gibson and used to treat arthritis-related inflammation at Glasgow's Victoria Infirmary in 1980. Lyprinol, which contains the oil, is used to support joint health and reduce inflammation. Mr Mickleborough said: "These findings are a real breakthrough."
