I have crohn's colitis (which is crohn's affecting my colon), I'm either allergic or non-responsive to tradtional oral RX so I had no choice but to put my skeptisism aside and try the "natural" route of which I'm glad cuz I have found a combination of products that have definitely helped (not full remisssion but much better than nothing at all) and best of all, no side effects. I also altered my diet (no more junky, processed foods, caffeine animal fats, refined sugar/artificial sweetners and I exercise regularly as well (also major help physically and emotionally in dealing with this disease). The alternatives (natruals) that I use are probiotics (primadophilus reuteri made by natures way) which are essential even if you take oral RX, fibre supplements daily and indefinitely as directed by my GI 5 yrs ago now, bee propolis (natrual anti-inflammatory which you should google for more info), omegas 3-6-9, vitamins A and C-Calcium Ascorbate (easy on the gut) both vitamins A and C are an excellent source for repairing damaged cells and such.
It's best to take a combination of things cuz it's not likely just one thing alone will be enough help and what works for some doesn't work for all so you have to try different things (giving them a chance to work as well as some things can take months before you notice improvements).
Bottom line from my experiance, I used to "go" 30+ times a day with lower back pain, blood, excess mucus and all, I now go on average 5 or less times a day, no blood, no lower back pain hardly any mucus (only on rare occassion) with formed stools...I still have frequency obviously cuz 5/day isn't normal for me (one/day was before getting sick) and urgency is also still an issue but I'll take whatever improvements I can get.
