"Why would you take Oxypowder or colosan instead of cascara sagrada."
Because cascara sagrada is more like a laxative where it irritates your colon and forces it to expel all the gunk. Oxypowder will be easier on your system plus it will also help to oxidize the mucoid plaque in the colon. If you do the Oxypowder than you won't need to do the P&B shakes either.
