*electrodermal screening, when used as a 'global diagnostic' is considered quite the pseudodiagnostic. Skin impedance can be used to calculate body composition, legitimately. The extension into 'organs', 'toxins' and the like is pure FANTASY.
001. Blair Watson, "former secretary of the BC Naturopathic Association", states in "Electrodermal Screening" [2013 archived here]:
"many Canadian natural health providers use electrodermal screening (EDS) to gather bioenergy feedback and find energy imbalances that may be symptoms of disease. Some naturopaths also use the devices to test for sensitivities to certain foods and other substances. How effective is electrodermal screening? Dr. Tom Glew, a naturopath who uses EDS in his Vancouver practice explains, 'electrodermal screening has been developing and evolving for at least 50 years [...] electrodermal screening is a useful adjunctive tool in the hands of a skilled practitioner. It helps determine functional imbalances or disturbances in the health of any patient and often finds the cause of an illness when conventional testing methods are unable to do so.”
yeah, right. Now, at ND Glew's web page, we learn that he is an NCNM graduate [2014 archived here]. And, of course, it is NCNM that teaches that the abjectly science-exterior in fact survives scientific scrutiny. So, is it not surprising that the ND doing pseudodiagnostics was miseducated? ND Glew uses Prognos EDS [2014 archived here].
