The utilization of alternative medical therapies and practitioners has increased dramatically in the U.S. in the last two to three decades. This trend seems paradoxical when one considers the rapid advances taking place in biomedical knowledge and technology during this same time period. Observers both inside and outside of the medical profession have attempted to explain the rising popularity of alternative medicine by proposing that it signals a growing sense of dissatisfaction and disenchantment with professional biomedical practices on the part of the lay public. This paper challenges this thesis and offers an alternative explanation, arguing that the rise of alternative medicine is a consequence of the success and expanding influence of biomedicine rather than its failure and declining authority. The argument presented draws primarily on Ulrich Beck's "risk society" perspective and theory of "reflexive modernization," with specific attention to his analysis of the "reflexive scientization" process. The application of this perspective allows us to understand the emergence and development of alternative medicine as an unanticipated consequence of the process of reflexive biomedicalization in the late modern era.
