Irritable Bowel Syndrome Treatment

I have to give this one a nay. I have in the past been able to take this herb with no problems as a sleep aid, but ever since my gastrointestinal problems got worse, I can't take Valerian without experiencing an IgE response. I can't see how this would possibly be healing to the gut given that reaction, and I would use it with extreme caution if you do have similar problems.
