ARCH the UK’s largest association for colon hydrotherapists

ARCH is the UK’s oldest and largest association for colon hydrotherapists, setting standards, promoting the industry and offering support for over 200 therapists nationwide.

ARCH is a community of like-minded people, run by members, for members, for the benefit of both therapists and their clients alike. We set standards that set ARCH therapists apart, and we work hard to promote, and occasionally defend, colon hydrotherapy in the media.

More importantly, we look after each other. ARCH offers a professional approach from approachable professionals, giving our therapists all the advice and guidance they need across every area of their business, from challenging cases to CPD courses.

We are active and dynamic in our drive to grow colon hydrotherapy in the UK, and to bring it into the mainstream so that more and more people can enjoy the many health and wellbeing benefits of the treatment.

Over the next few pages, we’ll show you why you should join ARCH and how to go about joining, as well as giving you some examples of ARCH in action in the media and through our charity work on subjects close to our heart.
