n this book, we will use the term ‘Integrative Medicine practitioner’ to denote a practitioner who is qualified in western medicine and at least one other form of complementary medicine (typically this is often nutritional medicine, acupuncture, an/or mind–body medicine). We will use the term complementary medicine’ to denote those systems of medicine and therapies that lie utside of conventional (western) medicine, which onetheless can be complementary to orthodox medical care. It is of course recognised that in defining it as such, we are taking a somewhat Western-centric approach and that in some countries, forms of ‘complementary medicine’ such as Chinese medicine would not be considered ‘complementary’. The term ‘complementary medicine practitioner’ will be used to denote a healthcare practitioner, whose primary qualification is in a form of complementary medicine and who is not qualified in Western medicine.
