Hananja has worked at the Archway Clinic since it opened in 1995, running three clinics a week. She has practiced Herbal Medicine extensively both in this country and in Switzerland, working in private practice, in clinics and in hospitals for over 20 years.

Born in Holland, Hananja was immersed in herbal medicine from an early age as both her grandmother and mother employed this traditional medicine to treat the family's illnesses. The step to professional study followed early, and she qualified first as a Naturopath in 1982 and then as a Medical Herbalist in 1990. Hananja has lectured and written regularly on herbal medicine, and as her professional standing has grown she is in increasing demand as a guest lecturer on her particular interests, gynaecology and paediatrics.

Hananja's practice marries science with tradition, using the knowledge gained from new research to enhance the established traditions of herbal medicine, including the crucial importance of nutrition to health. Her clinics draw patients, men and women, adults and children with a wide range of complaints. She is also seeing a growing number of patients with gynaecological problems referred to her by GPs and hospital consultants.
