This paper explores the joint roles of law and biomedicine in constituting the boundary between legitimate and illegitimate (and genuine and 'pseudo') traditional healing. It argues that, as law and biomedicine have grown to share common understandings of the nature of knowledge, they have come to act as converging colonizing forces that displace and alter 'other' forms of knowing and ordering. Even as regulatory systems set out to recognize some forms of traditional medicine, they continue to operate on assumptions that disqualify knowledge, products, and actors, that do not resemble their biomedical counterparts. This leaves traditional healing systems potentially having to either operate outside the law or adapt to it by transforming themselves, potentially beyond the point of recognition, to fit better into the systems provided by law and biomedicine. The paper explores the series of dilemma this creates for those seeking to 'regulate better' traditional medicine.
