Does marjoram effective for snoring?

The effectiveness of marjoram as a cure for snoring appears to be speculative, and not proven. The first several pages of google.com results on the subject return various commercial entities looking to sell marjoram as a snoring cure. The website http://www.buzzle.com/articles/marjoram-uses.html indicates a number of uses for marjoram, and they tend to focus on its benefit as an expectorant. This leaves open the possibility that it may aid with snoring problems by opening up the breathing passageways, but this effect would be secondary, and wouldn't overcome various other blockages leading to snoring that have more to do with sleeping position.
