Definitions and terms

Complementary medicine refers to a group of therapeutic and diagnostic disciplines that exist largely outside the institutions where conventional health care is taught and provided. Complementary medicine is an increasing feature of healthcare practice, but considerable confusion remains about what exactly it is and what position the disciplines included under this term should hold in relation to conventional medicine

In the 1970s and 1980s these disciplines were mainly provided as an alternative to conventional health care and hence became known collectively as “alternative medicine.” The name “complementary medicine” developed as the two systems began to be used alongside (to “complement”) each other. Over the years, “complementary” has changed from describing this relation between unconventional healthcare disciplines and conventional care to defining the group of disciplines itself. Some authorities use the term “unconventional medicine” synonymously. This changing and overlapping terminology may explain some of the confusion that surrounds the subject.

We use the term complementary medicine to describe healthcare practices such as those listed in the box. We use it synonymously with the terms “complementary therapies” and “complementary and alternative medicine” found in other texts, according to the definition used by the Cochrane Collaboration.
