Colonic irrigation — also known as colonic hydrotherapy or colonics — is a professionally administered treatment that uses warm, filtered water to gently cleanse the large intestine. At Phenomenal Colonics in Belsize Park, North London, Marijke Vogel has been delivering colonic irrigation for over 25 years, with an approach that goes well beyond simple cleansing.
What Is Colonic Irrigation?
Colonic irrigation introduces warm, filtered water into the large intestine via the rectum, softening and loosening accumulated waste, gas, and mucus. The treatment takes place lying comfortably on a treatment table and lasts approximately 45 minutes to an hour. Marijke uses the open gravity system, which she manually controls throughout — adjusting flow, pressure, and herbal preparation in response to how your body is responding.
Unlike an enema, which treats only the lower portion of the bowel, colonic irrigation works along the full length of the large intestine. Furthermore, Marijke incorporates individually blended organic Demeter-certified herbal preparations into every session — chosen specifically for each client’s constitution and health picture.
Who Benefits from Colonic Irrigation?
Colonic irrigation suits a wide range of people. Most commonly, clients come because of persistent bloating, constipation, low energy, or a general sense that their digestion is not working as well as it should. Others come as part of a seasonal health maintenance routine.
Marijke takes time to understand your individual picture before every session. As a result, the treatment she delivers addresses your specific needs rather than following a fixed protocol.
Is Colonic Irrigation Safe?
When performed by a properly accredited practitioner, colonic irrigation is safe for the majority of healthy adults. Marijke holds accreditation from ARCH — the UK’s longest-established colon hydrotherapy association, regulated by the government-backed CNHC. She uses single-use disposable equipment for every session and temperature-regulated filtered water throughout.
There are some contraindications — including pregnancy, active diverticulitis, and certain bowel conditions. The colonic irrigation FAQs page covers these in detail, and Marijke is happy to discuss suitability before you book.
What Happens During a Session?
Your first session begins with a short consultation. Marijke will ask about your health history, digestive symptoms, diet, and lifestyle before treatment begins. This informs the herbal preparation she selects for your session.
During treatment you lie comfortably, fully covered. Marijke remains present throughout, providing gentle abdominal massage and adjusting the treatment as needed. Most clients find it considerably more comfortable — and more relaxing — than they expected.
