About ten years ago, I purchased a homemade pillow filled with some kind of beans or peas and all sorts of soothing herbs, including menthol. It was sold at a crafts fair in a big city near here. You could pop it into the microwave for a minute or so and then put it around your neck. It felt heavenly. I would love another one of these, but I have no idea where to find one. Has anyone seen these?
