Hi I am a sufferer of Ulcerative Colitis for a couple of years now. Very depressing not just for myself but also all the others that were a lot worse than me. I found good concise details on what treatments did and did not work very hard to come by. Because of this I have created a free website where i have listed (http://****.com/conditions/1/ulcerative-colitis) and where other can list their own details http://whatwillworkforme.com.
And as for what worked for me, it was wild oregano oil. It wasn't a cure but it keeps it at bay (see the first link for more details).
Hope this helps someone :)
