Are menthol crystals edible?

Does anyone know where I can get edible menthol crystals?

Pure menthol can be harmful. If you dilute it significantly in other food items, it's edible, but you wouldn't want to eat the pure crystals on their own.

They can be purchased from Terra Spice, and you could try Le Sanctuaire; they used to carry them, though they don't seem to be listed on their site right now.

Type "menthol crystals" in google, all kinds of sources (mainly herbal store type places) will come up. I think I paid something like $5 for an oz. three or four years ago. You'll use tiny grains at a time, an oz. is a hefty supply.
