The cleanest way to describe colonics is you literally lie on a table with a tube inserted in your rectum and water constantly flows inward until you can't hold it in anymore. Most people can only hold the water for less than a minute and you continually take the water in and then release for an entire session usually lasting around 40-50 minutes. My tech adds Sea Salt and that really helps with the release of toxins. My goal is to clean out as much as possible and get to the root of my Candida Overgrowth which is in the cecum. Hope this not too much info!
