The centre, which is at the former Hartismere Hospital site, provides a range of holistic treatments, including acupuncture, hypnotherapy and reflexology.

As its name suggests, it aims to complement rather than replace orthodox medical treatment, sometimes taking patients who have been referred there by their GP.

"We have seen a real demand for these kind of therapies in the last few years," said homeopath and joint director Sue Saunders.

"People are taking responsibility for their own health."

Next Saturday, the centre is holding an open day to welcome anyone interested in what the therapists have to offer – whether they 'believe' in complementary medicine or not.

"The sceptical people are always the most interesting," said homeopath and joint director of the centre Lindsay Hickey.

"They are incredibly welcome – we would love to see them. The sceptical people are the most interesting converts because they tell people all about their experience."

The day will include a herb walk in the countryside around Eye, aimed at teaching people what nature has to offer and a series of taster sessions and workshops in techniques such as Indian head massage and meditation.

Health checks for blood sugar, blood pressure and mineral deficiency will also be available to visitors.

"The open day is very much about involving people rather than just talking at them," said Mrs Saunders.

"It also gives them the chance to talk to the therapists and find out what is available here."

All therapists working at The Complementary Medicine Centre are regulated by a professional board.

Their skills include aromatherapy, chiropody, herbal medicine, podiatry, and pre-conceptual care – for couples trying to have a baby.

The centre also offers daytime and evening classes including yoga and Pilates, which are becoming increasingly popular.

"Most people come to the centre through word of mouth," said osteomyologist and joint director Nic Aldous.

"If it hadn't worked for them first they wouldn't have told anyone else about it."

Entry is free to the open day, which runs from 10am to 4pm on the Hartismere Hospital site in Castleton Way.

Any proceeds raised, including money from the raffle, will go towards the East Anglian Air Ambulance.
