Butler's ISBN 0763793396 978-0763793395 (2012) on Naturopathy

here, I cite from a 2012 consumer protection book's entry on naturopathy published by Jones and Bartlett Learning: 

Butler, J.T. (EdD {health ed.} UT) states in "Consumer Health: Making Informed Decisions" (2012; ISBN 0763793396 978-0763793395):

"'naturopathic medicine' or 'natural medicine' [...] according to Barrett (2003), naturopathy is largely a pseudoscientific approach.  It fails to meet the standards most people would require of the practice of medicine, including scientific evidence of effectiveness and a long period of training of practitioners based on scientific principles [...] practitioners claim that diseases are the body's effort to purify itself and that cures result from increasing the body's 'vital force' [p.114...] the notion of vitalism, also referred to as 'vital force' or 'life force', originated in ancient times and is the basis for a number of alternative therapies including naturopathy.  There is no scientific evidence supporting vitalism.  In fact, science, including organic chemistry, contradicts it [p.115...] unscientific naturopathic beliefs pose irrational challenges to proven public health measures, and irrational unscientific beliefs and practices, which are standards in the field, abound in naturopathy [p.116]."

Note: hear, hear.
