They also contain high levels of vitamin C (1700 – 2000 mg per 100 g dried fruit) and have been used to treat and prevent asthma and colds.
And now a recent study has found an extract from the seeds and shells of rose hips have anti-inflammatory properties.
A study published in 2005 in the Scandinavian Journal of Rheumatology details the research into testing of rose hips to treat osteoarthritis. This study included 80 participants, all over 35 years of age and all with osteoarthritis of the knee or hip. The participants were required to stop any use of glucosamine, chondroitin, and any steroid at least 6 weeks prior to beginning the trial.
During the first 3 months of the randomized, double-blind study, half of the group received 2.5 grams rose hips extract twice a day or a placebo. The treatment was stopped for 14 days and then the groups were reversed for another 3 months. The participants completed questionnaires at three weeks and at the end of the 3 month period to evaluate their level of pain, stiffness and overall desease severity. They also recorded their use of NSAIDs and pain relievers.
After three months the group using the reported significantly less stiffness, disability and overall disease severity. They also recorded a 51% decrease in use, the pain reliever most commonly used by the entire study population.
Pain levels were also lower in the rose hip group after 3 weeks; however, after three months the pain levels were not statistically different.
In another 6 month study, 74 rheumatoid arthritis sufferers, mostly women, tested the rose hip supplement LitoZin. Half of the group received the supplement while the other half received a placebo. They all continued taking their usual medication.
The LitoZin group reported a 25% improvement in activity with a decrease in the number of joints causing pain or discomfort of 40%.
