Whiffing lavender oil during your next dental visit may blur the memory of your pain. Researchers at the University of Florida College of Dentistry exposed 13 men and 13 women to uncomfortable heat and pressure on muscles in the jaw and back and then had them inhale lavender or an odorless control for 10 minutes during different sessions. The lavender oil significantly reduced the memory of pain's intensity and unpleasantness. How to use it: Shake 5 to 10 drops of lavender essential oil onto a tissue; inhale freely during dental work. - Prevention (January 2005)
