Peppermint and Christmas

I don't know other people are curious or not why most of new receipt on Christmas season always have peppermint: peppermint drink, peppermint candy, peppermint cupcake/ cake... etc. Perhaps, I don like it that's why i always notice about it. "why is peppermints associated with Christmas?" I had surf internet few times but still no answer. when i can't find thing that i'm looking for it make me more curious about it.
(smiling myself) this series make remember my master classmate who said i'm a curious person. I always wonder and want to know everything around me.
