Kiss,
I read Listen to Your Gut, by Jini Patel Thompson, a lady who has managed her IBD without drugs.
She talks about aloe vera. She recommends George's Roadrunner Aloe Vera because it's supposed to have the thing that can cause diarrhea removed from it.
It didn't cause me to have diarrhea; however, that's never been a problem for me anyway. The best thing is, it's really cheap! I bought a large bottle for around $6. Bad news, it didn't seem to help me. But, everyone's different.
HTH,
Beth
