Haven't there been some experimental treatments with parasitic worms, on the theory that an autoimmune reaction is involved (some remarkable remissions) or is that for another intestinal disorder?
I think it is HMSO's or homeostatic soil organisms (not really worms) and probiotics that Jordan Rubin used in overcoming the disease, along with a specific diet (really a very good sound diet). I'm going to read The Maker's Diet again. I went on the 40-day program he suggested; but I don't have ulcerative colitis. The book just rang true to me, and I would feel better if I would just stick to it closer all the time.
The worms are 'helmenthic therapy'. Look up Dr. Joel Weinstock. It is being used in Europe.
