I once showed up to work sick with a VERY stuffy nose, and took non drowsy allergy pills to help. They didn’t. Instead I became loopy and could not focus on my work no matter how hard I tried. My manager put a few drops of this oil in boiling hot water and had me inhale the steam. Immediately I was cured. Now every time I start feeling a little stuffy I just drop a few drops of this oil into my shower and inhale the aroma.
