Q. If I smell the cloves liquid for the dubious medicinal benefits or the mint stuff to clear the sinuses, but also have pleasure from the smell, do I make a Brachah?

A. Shulchan Aruch (O.H. 217: 2 – 3) rules that you do not recite a blessing on aromas that were created for other purposes such as masking a bad smell, even if you have intention to have pleasure from the pleasant aroma (Mishna Berurah ibid. 9)

Horav Shlomo Miller’s Shlit”a opinion is that this applies equally on scents that were created for medicinal purposes.
