The more popular complementary and alternative medicine (CAM) has become, the more often it is demanded that the integration of CAM should be limited to those approaches that are scientifically proven to be effective. This paper argues that this demand is ethically and philosophically questionable. The clinical legitimacy being gained by CAM and its increasing informal integration should instead caution against upholding the biomedical framework and evidence-based medicine as conditions of acceptance. Patients’ positive experiences with CAM deserve a truly scientific (...) exploration of non-biomedical conceptualizations of health and illness. It is also problematic to request scientific evidence when there is proven resistance against CAM in research institutions, under-funding and a lack of suitable research methodologies. This is even more so, when much conventional medicine is not practiced with the same level of evidence as demanded from CAM. (shrink)
