Cecil's probably already answered this one, but...

…I can’t find it anywhere.

Why does menthol feel like it “cools” your mouth down? Poorly worded, I know, but you all get the gist.

Try this one out. http://boards.straightdope.com/sdmb/showthread.php?threadid=4775 You have to wade through some smartass antics (usually better than answer) but you’ll get there.

This seems like spouting. I don’t believe word of it.

Specifically, what makes MINT (peppermint, spearmint, trebuchetmint, I don’t care) so “cooling”? The thread had a lot of suppositions, like ‘heat’ and ‘lack of heat’ but they all seemed like copouts.

I really couldn’t care less about what the chemical compounds are; I’d like to know why it is that menthol (mint, eucalyptus, etc.) makes your mouth feel “colder” when you suck air or drink a cold beverage afterwards.

For the record, I understand that mint doesn’t make you feel cooler. It merely presents the topical sensation of coolness. But why?

Impressive Arnold Winkelried! I looked in a few global search engines because the question intrigued me but couldn’t find squat. I’m not the OP but thanks!

Thanks Arnold! Exactly the answer I was looking for!
