During the private 45-minute procedure, clients relax as a soothing stream of warm water flows through the intestine's labyrinthine passageways, scouring every inch of its walls for excess bits of waste. The safe, gravity-fed open system employed ensures that more water isn't forced into the body than is necessary, and works in tandem with an ultraviolet water-purification system that provides innards with only the cleanest aquatic scrubdown.

Colonic Center of America

Colonic Center of America's team of therapists attends to clogged interiors in a comfortable setting with its gentle, FDA-approved cleansing-hydrotherapy treatment. The center uses the LIBBE system, which can be operated privately or with the assistance of a therapist. Sessions take place in private rooms, and clients don appropriate draping to maintain comfort and peace of mind. The filtration system removes all traces of offensive odors, ensuring a sanitary experience. Before treatments, clients are advised to drink plenty of filtered water, eat organic vegetables and fruits, and avoid swallowing marbles.
