Are there any natural ways to treat ischemic bowel disease?

Some: Keep hydrated. Stop smoking. Use fiber. But otherwise no - we can make it better but cannot cure it without surgery.

I'll try to explain: Ischemic disease is from the build up of sludge or blockages in the arteries of the body over a lifetime. This happens in all of the arteries, the heart, the intestines, the legs etc. Too much blockage leads to too little blood flow and produces symptoms of pain etc. First step in therapy is hydration, but, there is a mechanical blockage that is not able to be reversed by anything we now know.
