Colon Hydrotherapy makes me a little nervous. Just because for me, I don't want anything going in that hole. I have also heard many horror stories of inexperienced hydrotherapist's. However, I would also be very hesitant on doing the "At Home Enemas," while they are beneficial and cut down on the "embarrasment factor," I don't think they would be more beneficial than a product.
On the plus side, It's very encouraging to see the youth taking such an interest in their health. Most twenty somethings would be closed out to the idea of colon cleansing.
