I have read a lot about the benefits of Colosan (I have no vested interest in the product, am ust impressed by a few people who've recommmended it-and what I have read).
Colonics can be very helpful for people who are into cleansing, juicing and such simply because the toxins the body is now able to release are not able to leave the body fast enough, and then recirculate--this is a situation parasites like. The thing with Colosan is, that it easily and without any harsh substance dissolves the waste that is built up in the colon. And best of all -so I read- there is no "urgency" to the process. No having to get to a bathroom quick. Also, no cramping, as with some of the herbs. It's a thought, anyway. Check it out.
