As far as I know, no peer-reviewed article has been published on the successful treatment of nausea with green apples.
There is a 1998 study published by A. Hirsch and C. Kang in an obscure journal, Headache Quarterly, about the use of the scent of green apples to diminish migraine headache pain. It didn't work in all 50 subjects -- 35 of the subjects didn't like the smell and reported no significant difference in pain.
@Surface Interval: I wouldn't be too quick to write off the study.Considering 2 of my migraine triggers are light and smell and "they" say the scent of the apple didn't help over half of the participants...I have to decline your nonscientific study.
But I will see if my son can do his science experiement on it next year! (But not on me!)
The authors hypothesized that if certain smells could trigger migraines, then perhaps other smells might reduce migraine pain. Since there were reports in the literature of green apple aroma reducing anxiety, Hirsch decided to test whether the smell might reduce migraine pain. 50 chronic headache sufferers (frequent migraines?) participated in the at-home trial which focused on the next 3 migraines that they experienced.
For headache #1, participants were instructed to rate the headache on a 1-10 scale, lie down in a dark quiet room for 10 minutes, and then rate the headache again.
For headache #2, they were asked to rate the headache and then smell a vial of green apple odorant, rating the smell either "pleasant" or "unpleasant." While smelling the vial, they were told to lie down in a quiet dark room for 10 minutes. After the 10 minute period, they were asked to, once again, rate the headache pain. For headache #3, subjects repeated the instructions for headache #1.
For the 15 participants who found the green apple smell "pleasant," all reported significant reduction of headache pain after smelling the odorant for that 10 minute period. Weird, huh? There's definitely a psychological component of pain that might be accessible to unconventional treatment.
The take-home message for me is that it might be worthwhile to identify a unique smell that you find "pleasant" (not necessarily the odor of green apples) and expose yourself to that smell after the onset of your next headache. It just might make you feel better.
