Colon hydrotherapy, massage therapy, lymphatic drainage, and holistic healing modalities to help you look and feel your best. Colon hydrotherapy, also known as a colonic or colon irrigation treatment, is a safe, effective method of removing waste and toxicity in the large intestine without using drugs. By introducing warm, filtered water into the colon, waste is softened and loosened, resulting in evacuation through natural peristalsis. This process is repeated a few times during a session.
