Skeptic Club - CAM

As part of the Budapest Skeptic Club Gábor Hraskó holds a lecture under the title "Alternative thoughts". The Skeptic Society published its manifesto on alternative medicine ten months ago. Alternative, natural, complementer, holistic - or as it is called by the official regulation - non conventional therapies. What is the common in these practices? Why do skeptics criticise them? Should they? How? What is the legal and social position of these practices in Hungary?
