It is not necessary to cleanse the colon by enema or any other means. Even if you do that, the bacterial population re-establishes itself in 14-48 hrs. You are wasting your time and money. Eat healthy and have regular bowel movements. No need for anything else.

Enema is unable to cleanse the entire colon, it works only on the lower left side of the colon. It’s meant to be used as needed for people with constipation.
