I tried RenewLife's CleanseMore the other day and it was great. It contains magnesium, cape aloe, rhubarb root, slippery elm, marshmallow root, and triphala. The magnesium (I think) even made a headache I was experiencing at the time subside. (I made my own Intestinal Formula #1 and it was strong with the senna and other laxatives but CleanseMore is more gentle, yet effective.)
BTW, thanks for sharing all of the great information!
