they can and do give proper medical advice on the medical products they are selling but at the same time they are selling homeopathic products and other magic pills, powders and devices from the same counter. This seems conflict of interest / ethics. I am not sure why pharmacies are not regulated but that is the way it is in Austria.
It's unfortunately surprisingly common for doctors and nurses to recommend all kinds of quack treatments in Austria. The pharmacies are not the only profiteers of these scams.
