A colon cleanse refers to methods used to flush waste from the large intestine. Commercial colon cleanses, including colonic irrigation and herbal cleanse kits, have no proven health benefits.

The fastest natural constipation relief comes from warm water, prunes, and correcting your toilet position. For most adults, increasing fiber to 22–34 g/day, drinking 8–10 glasses of water daily, and walking 20–30 minutes resolves occasional constipation.
