My otolaryngologist (a.k.a. - ENT) uses a mint infused nasal spray to lubricate my nose. I once asked him to show me the spray bottle and the ingredients includes peppermint. Similarly, one of my regular nasal sprays I use home contains rosewater as one of its ingredients.
If I enjpy the smell of the mint or rose water while I'm using the spray, do I need to make a bracha (borei minei bsamim)? The primary purpose is not for smelling the spice in there; the smelling is secondary to my use of the spray.
