A pill made from rose-hip extract has been found to reduce the severity of pain of osteoarthritis sufferers by an amazing 90 percent.
Human trials suggest a wonder supplement called Gopo - named after a key ingredient of the plant - could provide a breakthrough for six million Britons whose lives are blighted by joint pain.
Pills containing the supplement are now available in the UK for the first time - for just 15 pence each, the Daily Express reported.
Scientists said that they have proved the herbal remedy possesses special properties which can alleviate the condition in the hand especially.
Danish researchers found the specially cultivated compound reduced nagging pain in nine out of 10 of the 30 people who took part in clinical trials.
Debilitating stiffness in finger and thumb joints - the calling card of osteoarthritis - can make tasks like opening jars, holding cutlery and tying shoelaces near to impossible.
The results of investigations carried out at Frederiksberg University in Copenhagen show the natural extract could offer the closest thing to a cure.
The pill gave round-the-clock relief, and sufferers were a third less likely to use conventional painkillers after taking the supplement.
Rose-hip, also known as rose haw, is the fruit of the rose plant and is commonly used for jam, jelly, syrup, soup, wine and marmalade.
It contains high levels of vitamin C and lycopene, a powerful antioxidant that helps lower cholesterol.
Gopo was discovered more than 20 years ago in Denmark. The compound is extracted using a special patented process after drying rose-hips.
The findings are published in the Open Journal of Rheumatology and Autoimmune Disease.
