What's Wrong with Alternative Medicine?

If unconventional therapies like acupuncture can make patients feel better by bringing them a vague sense of well being, why not let them? Some scientists say we shouldn't.
It's safe to say that most everyone allows for some form of mysticism in their lives. If you'll permit the oversimplification, one can imagine a spectrum of tolerance: At one extreme we have those who welcome with indiscriminate, crystal-clutching gusto the spiritual, the transcendent, and the utterly bogus. At the other end stand the most fanatical of skeptics, the ones who revel not so much in ruining your fun as nuking it from orbit in an eye-rolling fit of vitriolic contempt.
