All I can find from the makers is it has 100 ingredients, I didn't see where I could get the list, but mostly because the page I was on was so full of misinformation and hype I couldn't take it any more.A few board messages I found by googling mentioned fiber and senna. Both of these things are available pretty cheap in a lot of places.Most colon cleanser products do not do anything to clean the colon, but contain ingredients to make you poop. Senna, cascara, aloe latex, and others are stimulatory laxatives. Some have lots of fiber in them but no laxatives. Some have a lot of osmotic agents in them.All will make you poop. Usually if you put cleanser on the label you can charge more money than one would pay for the same thing called laxative or fiber supplement.K.
