ABC of complementary medicine: What is complementary medicine?

Abstract
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.
