CAM used widely outside the U.S.

The term "traditional medicine" is used differently in the U.S. and abroad.

In the U.S. we often refer to allopathic or orthodox (aka conventional) medicine as traditional, but WHO uses traditional medicine as a term of art.

In fact, this is from an article entitled TCM:

Abstract

The use of Traditional/Complementary Medicine (T/CM) is widespread in developing countries and is steadily increasing across the developed world. The World Health Organisation (WHO) estimated that "In many countries, 80% or more of the population living in rural areas are cared for by traditional practitioners. About half the populations of developed countries regularly use T/CM. The United States of America's expenditure on T/CM increased from $13 billion to $38 billion per year in 1990-7. The same trend is seen in Australia and in the United Kingdom. By 1993, it was estimated that Australians were spending almost twice as much on complementary medicines (CM) ($AU621 million yearly) than their contributions to pharmaceuticals. Recent government estimates revealed that each year 57% of Australians use some form of CM. A survey in Southampton (with a population of (200,000) revealed that about 4 million pounds were spent a year on T/CM outside the National Health Service. At least 40% of general practices in the UK provide some complementary services. In China, T/CM accounts for 30-50% of the total medicine consumption while in Hong Kong, 60% of the population has consulted TM practitioners at one time or another.

So you say traditional, I say non-traditional: it's all a matter of perspective.
