**6. Conclusion**

Rose hip is a very fascinating medicinal plant, which deserves much attention. It can grow on very poor soil, and it is a source of very potent antioxidant and antiinflammatory agents. It is also a rich source of vitamins—especially vitamin C. Several clinical studies have established that rose hip is very effective for the treatment of osteoarthritis in humans and also in some animal models. Very important, dose dependency, one of the cornerstones when evaluating prescription medicine, has been documented for a subspecies of rose hip [60]. There are also indications that conditions such as rheumatoid arthritis, cardiovascular disease, and skin diseases including wrinkles can benefit from rose hip treatment. However, there are many different *Rosa* species that produce rose hips with varying contents of active compounds. Only careful comparative evaluation will establish which species are most promising. Currently, it seems like a certain subspecies of *Rosa canina* Lito is very promising. There is still a tremendous amount of research to be done before we have a clearer pattern. But for sure, rose hip is a medicinal plant with a long and fascinating history. When discussing anti-inflammatory diets and anti-inflammatory plants especially it is interesting to note that in osteoarthritis a subspecies of *Rosa canina* was able to reduce the consumption of rescue medication by up to 50%. This means that we can eat in a different way and possibly, spare governmental health expenditure for medicine. It has been very interesting to be part of this research.
