In conjunction with its growing popularity, complementary and alternative medicine (CAM) in the United Kingdom has witnessed increasing professionalization, partly prompted by the landmark Parliamentary Inquiry that reported in November 2000. Professionalization has become a significant strategy for practitioner associations and a key focus for the government, media, and patient groups. It is being driven by concern over the interests of patients and consumers, and in relation to the possible integration of certain forms of CAM into publicly funded healthcare. It is, moreover, being reconfigured in explicitly national terms. This paper draws on research into practitioner associations representing nine CAM modalities in the UK—aromatherapy, Chinese herbal medicine, chiropractic, crystal healing, feng shui, ‘lay’ homeopathy, medical homeopathy, osteopathy, and Radionics—, examining the recent wave of professionalization in relation to Foucault's concern with ‘techniques of the self.’ It highlights the contrasting experience of an association of Chinese herbalists seeking statutory self-regulation (SSR) and an association of chiropractors that was instrumental in securing SSR for chiropractic.
