I have been taking a 450mg valerian root capsule each night before bed for the past week and it has led to a marked improvement in my IBS-C symptoms. It might be due to the fact that valerian has a slowing/calming effect on the body and has allowed my digestive system to relax somewhat. The one night I missed a dose, my crampy/gurgly symptoms started coming back during the day, so I am positive that it's the valerian that is helping.
