Peppermint Travel Pillow

I found this in "The art of Aromotherapy", this can help with motion sickness in the car. Make a soft neck cushion and fill it with:

1/4 cup peppermint
1 tablespoon mint-scented pelargonium (mint scented flower)
1 tablespoon lemon verbena
1/4 cup lavender
1 tablespoon of crushed lemon zest
