Lucinda is correct, it is an antiinflammatory... but the probiotics I can help you with. According to a study done on
www.VSL3.ca for UC is it sought that Asacol (Pentasa, salofalk...sister drugs) and high count probiotics are a good combination to keep flares in check.
I am on the VSL and so far hasn't done a whole lot but it helps. Everyone should be on some sort of probiotic, is natural and helps the digestive system and wards off yeast and some other autoimmune disorders.
Best kind are the refridgerated kind or even Activia yogurt if you can have that. Good luck.
