Hi just thought I'd let you all with IBS-C, know that I have been using a natural laxative named Colon Max, which I purchase from Advanced Naturals. Over the years I have tried many laxatives both prescription and over the counter, but have found this product very good. I do not get any griping pain. It contains Magnesium, Marshmallow, Slippery Elm, Cape Aloe, Rhubarb and Triphala. It comes in capsule form, and I now open them up and find that half of the powder is plenty to make my bowels work the next day. We are all different but I take my dose about 3pm and go to the toilet after breakfast the next day. I would recommend that you don't have to go out the next day until you have found the correct dose that works for you. I hope this this helps some of you find relief.
