Read the link Hanna gave you, its the best way to learn what its all about.

I would not recommend combining P&Bs with the Oxypowder . I do think that doing the Oxypowder first, then using P&Bs for a couple of weeks after would be an excellent way to cleanse. There are so many options in colon cleansing, it usually depends on what your issues are to decide what will work best. Those with more than one problems may have to do more than one cleanse.

Constipated, clogged colon~Use magnesium based product like Oxypowder

Little or very weak perstalsis~Use a stimulant herbal laxitive like Intestinal Formula#1 or LLB

Regular BMs, but tend to be small and narrow~Try P&B shakes or other fiber based cleanse
