Because of the adoption of pseudo-science complementary medicine is an easy target for researchers such as Edzard Ernst. There is enough quantitative science papers already written to prove the efficacy of several herbs, and nutrition has been incorporated into mainstream medicine for many years. Can anyone argue that accurate evidence based information delivered in consultation, is anything less than invaluable?
How many lives has a practitioner, imparting accurate advice at an appropriate time spared? Dietary advice for lowering cholesterol levels, high blood pressure, obesity, high sugar levels has saved how many lives? During a consultation with a naturopath many people have learned to address their stress triggers and respond accordingly.
Some naturopaths become engrossed in qualitative science where the researcher commonly searches for meaning and insights in a given situation, the data is normally given in words rather than numbers. Quantitative science on the other hand relies on objectivity where some form of measurement or quantification is made in numerical terms. Qualitative science brings knowledge into view whereas quantitative researchers take something they know about and by applying numerical measures to data and using statistical techniques to analyse the results, researchers attempt to generalise their results to a wider population.
Quantitative research is used to prove whether a treatment works or not and how far it can be extrapolated into the wider community.
Different countries have different standards, Australia has a pretty high standard (not as high as I would like) for advertising health advice and products, in Australia you must hold proof, and supply it on demand, for every piece of advice or product that you advertise, and a first offence can attract a penalty as high as a $25,000 fine and they get tough after the first offence, the Therapeutic Goods Administration has the responsibility for this.
In the USA it seems to be completely different, the Food and Drug Administration will allow anything as long as it doesn't directly harm you, this allows 'shonks' to ply their trade of deceit by advertising absolutely useless products and advice, pseudo-science screams at you from every corner. Advertisers can claim cure for something with impunity from law enforcement as long as it doesn't harm people directly.
I will finish by adding something that I found sad, but funny.
