L.O.
I would never trust something like that and it appears many others agree. Our bodies were created to "cleanse" itself so we are responible of getting the best fuel (food) to allow it to do what it was designed to do. Fiber is a key element. I use the Reliv products and they have been poven to be effective. The Fiberstore product is probably the best in the world - it is patented food product with soluable and insoluable fiber. I no longer suffer with hemorrhoids and I credit this product.
