Classifying knowledge used in complementary medicine consultations: a qualitative systematic review.

Background: Complementary Medicine (CM) is widely used internationally but there is limited understanding of the forms of knowledge CM practitioners use in their clinical practice and how they use this knowledge in interactions with patients. This review aims to synthesise the existing evidence on the forms of knowledge that are mobilised, and the role of this knowledge in the interactions between practitioners and patients during CM consultations. It considered a diverse range of CM practice areas to develop a classification of CM practitioners' knowledge use in consultations.
