maybe we could use the pulp/fiber from the juicer and add it to water?

if you want to cleanse your colon you need to do something like fiber or an alternative would be Oxypowder . It is about $40 for a bottle but totally worth it. The Master-Cleanse and juicing will do some colon cleansing, but nothing nearly as effective as fiber or oxy, or even colonics. I also like enemas for colon cleansing. there are many types. I do organic coffee to cleanse the liver. But you can do just warm water, garlic, baking soda, and so on. Just depends on what your goals are. I do one enema a week for maintance, and Oxypowder when if I get constipated. Liver Flushes are important too,. There are so many options !! So what are you trying to achieve is the real question?
