Viateur, A good place to start searching the medical literature is Medline (includes mostly English language journals, but also some journals in other languages). Free access to the database can be found at pubmed (http://www.ncbi.nlm.nih.gov/pubmed/). The keyword "salep" brings up only four articles, three of them over forty years old. I would tentatively conclude that there is no medical evidence for any harmful effects of consuming salep. Certainly, it does not seem to be an active field of research, unless it is a hot topic in Turkish journals that are not indexed by medline..
