This inhaler is good at times of colds and stuffiness. If you are extremely sensitive to smells, take a whiff of this and it will let your mind think about something other than that which just passed by you--either someone who hasn't had showering opportunity or strong cologned man or perfumed lady.  Wonderful Essential Oil Blend of Eucalyptus, Lemon, Peppermint and Rosemary. My one sister cannot enter a new building for about 2 years...time for the new smells to lessen.  She can't stand most perfumes and colognes or certain isles in the grocery store with many chemicals in them.  When it gets very bad, these things affect her as if intoxicated.  She sniffs of this inhaler to enable her to get to her medication.  She also keeps it on her person, so it is handy.
