here, I cite from a recent blog post by scientist Larry Moran on his Sandwalk blog here on blogspot:
"I really don't know much at all about the differences between 'naturopathic medicine' and quackery [...until I] look[ed] at an authoritative source, the Canadian College of Naturopathic Medicine right here in Toronto [...from their definition] now I know the difference between naturopathy and other forms of non-evidence based medicine (i.e. alternative medicine, quackery). There isn't any."
Note: yes! I must credit the Richard Dawkins Foundation web page for this lead.
