💙 WHAT EXACTLY IS ARCH — AND WHY DOES IT MATTER?
You may have seen the ARCH logo on a colon hydrotherapist’s website, social media page or displayed in their clinic — but what do those four letters actually represent?
ARCH stands for the Association of Registered Colon Hydrotherapists.
Established in 1987, ARCH was created to bring professionally trained colon hydrotherapists together within an association committed to promoting high standards of professional practice, safety, education, care and ethics.
Nearly 40 years later, those principles remain at the heart of everything ARCH represents.
💙 But what does that mean for you, the public?
Choosing a complementary therapist involves trust. You want reassurance that the person you are placing your care in has appropriate training, works professionally and responsibly, understands safety and recognises when treatment may not be appropriate.
ARCH provides a professional framework for its registered members, with clear standards of practice, conduct and ethics that members are expected to uphold.
📚 ARCH also encourages ongoing education and continuing professional development, because becoming qualified is only the beginning. Knowledge and professional practice continue to evolve — and therapists should evolve with them.
🤝 ARCH provides a register of therapists who have met the association’s membership requirements and committed to working within its professional standards, helping members of the public make a more informed choice when looking for a colon hydrotherapist.
Behind the scenes, ARCH supports its members with professional guidance, education and a community where knowledge and experience can be shared.
So when you see those four letters — ARCH — they represent far more than simply belonging to an association.
They represent a commitment to:
💙 Professionalism • Education • Safety • Care • Ethics
ARCH — More Than Four Letters.
💙 A community built on safety, standards, care and ethics.
