Depression is often associated with a number of chronic diseases. Diabetes is one such disease where patients are at a higher risk of developing depression. Treatment strategies surrounding depression therefore have not only to consider the defects to the insulin system, but also any underlying mood disorders. Evidence suggests that certain phytochemicals may be useful in the treatment of depression. The rose hip tree, also called the dog rose, may be one such treatment. In one study, researchers administered post-flowering rose hip extract to diabetic mice and then exposed them to experimental stress to induce despair. The results of the study showed that the rose hip extract was able to significantly reduce the depressive-like symptoms in the animals and was also able to attenuate the reductions in memory that accompany this behaviour. Rose hip extracts may therefore be a useful treatment against mood disorders, and could potentially be used to treat depression associated with chronic diseases such as diabetes.
