Very solid book examining the scientific evidence on a number of different alternative therapies. The conclusion? Chiropractic and herbal medicines can be helpful, but are not demonstrably more helpful that evidence-based, modern medicine, and are sometimes more dangerous. Everything else (reflexology, homeopathy, iridology) is pretty much bunk.
Perhaps the best parts of the book are the explanations of why alternative medicines are appealing (they give hope and their practitioners are better at marketing) and why the appear to work (time, placebo effect, and using alternatives after modern medicine).
Very helpful as I explore and struggle with why alternative medicines are so appealing to faith communities.
