In defence, many practitioners argue that research methods dissect their practice in a reductionist manner and fail to take into account complementary medicine's holistic nature leading to invalid evaluation.
Summary points
Complementary medicine has a different philosophy from conventional medicine, presenting challenges to research methodology
Rigorous evaluation of complementary medicine could provide much needed evidence of its effectiveness
Good design of randomised controlled trials will avoid invalid results and misrepresentation of the holistic essence of complementary medicine
Practitioners need to be recognised as a component in or contributor to complementary treatment
Both specific and non-specific outcome measures with long follow up are needed to adequately encompass the essence of complementary medicine
