Why Choose An Open System Colon Hydrotherapy Device

Often dubbed the “Rolled Royce” in colon hydrotherapy, the Open System Colon Hydrotherapy Device has many more benefits when compared to a closed system. As a Colon Hydrotherapist registered with I-ACT, the International Association of Colon Hydrotherapy, here are a few reasons why I use this (and only this!) system for all of my clients at Refresh Health.

  • It’s much more comfortable since it has a smaller rectal tube.
  • An open system is much safer and more gentle because it’s gravity-fed (meaning no pressure!).
  • Since it's gravity-fed, it also helps with peristalsis (the muscle movement that allows food to easily go through your digestive tract).
  • It’s more effective than other systems since the water runs continuously, which, again, gets things moving!
  • Since fecal matter doesn’t actually come out of the tube, this system allows you to pass everything (even large stools!), so you feel fully emptied,
  • The open system allows for optimal privacy since you easily insert the smaller rectal tube yourself as opposed to the therapist doing it.
  • It eliminates the need for any massage with colonics to get things moving due to its effectiveness at softening the stool and triggering peristalsis.
  • The maximum time on an open system is 45 minutes, which prevents too much water from being absorbed or worked through the kidneys.
  • You can actually urinate during your colonics appointment! This is crucial for many patients since colonics cause the body to absorb plenty of water, which can lead to significant discomfort (and an urgent need for the bathroom!), especially in the last few minutes of your session.
