I make them myself! I buy the best peppermint essential oil I can find and I have some aromatherapy rollers on Amazon.
Then I add 5 to 10 drops of the oil to the bottle, top it off with almond oil or something like that and then put on the roller top. Put on the lid, and shake it and then remove the top. Roll it on your hand and check the scent, opening it up if the roller needs more and then I roll it on my forehead and temples when needed.
And I might have migraines then because I can’t stand light when the headaches strike.
