In addition to the article by Dr Premchand here is a useful summary of some relevant studies into the health benefits of prunes that have been published in the medical literature.

Inflammatory bowel disease (IBD) is the name given to a collection of otherwise unexplained symptoms relating to a disturbance of the digestive system, and which includes ulcerative colitis (UC) and Crohn’s disease (CD). It is a recurrent chronic disorder, and neither the process by which it originates and develops nor the precise effects of the disease on the body are completely known, however it is thought that they involve both genetic and environmental factors. 

There is general agreement amongst health professionals that a healthy diet, regular exercise, a good intake of water and less stress will all contribute to self-managed digestive health, but what if you are finding it difficult to get the right balance of these factors? Fibre is not a new phenomenon, and there has long been an awareness that unrefined foods can help to promote health and longevity. Research has been ongoing, but despite this more and more fibre-depleted foods have found their way into our diets. Your lifestyle, age and health issues may mean that maintaining a well balanced diet and being active are not always possible.
