Complementary medicine and the placebo effect is the theme , and part of the
might be to examine how different countries are tackling it . this has
still be whole, can not be too fragmented , it is not possible to dive
deep up in one MA thesis .
I think its needed to be aware of the red thread , which is complementary medicine and Placebo effect, then everything else, all references to related and
discussion about it. Do not have anything inside that does not benefit the discussion . If Discussion of pharmaceutical related then it is ok, for example if used To clarify the relative position of complementary medicine or something .

Here are some sources i want in the paper (with the other 11 you will find):
