Review of Senna Tea

Ok, I'll edit this later and post a pic of the brand of Senna tea that I bought, but I'd honestly rather deal with magnesium citrate than this tea. I took it around 6:30 PM last night and I followed the instructions on the box to a T. It said that it would take between 6 to 12 hours to set in. It is almost 10 in the morning. It took almost 16 hours to set in. When I take something that says laxative on the box, I want it to work faster than that. Overall, I'd probably take this tea again, but I'd have to have something to do that would make me want to delay my bowel movements.
