Usually, alternative medicine is a harmless distraction. And some treatments actually do offer benefits. But going outside modern medical practice also carries dangers.
"Alternative medicine is not so much about the treatments we discuss in this book," the authors write, "but about the therapeutic relationship.

To bring all treatments in line with rigorous science, an "excellent relationship" between doctor and patient is a good place to start.
