Many of my customers that suffer from headache report relief with my simple blend. I have tested many more complicated blends but like this one has been the best by far. It's made with pure Essential oils of Peppermint and Eucalyptus, To use, just roll on and rub lightly into the temples and the base of skull. Or, roll on on a cotton ball or tissue and inhale for a 15-30 seconds. it's best if you use at first sign of headache. It can also be diffused in your favorite diffuser or nebulizer. We also stock a larger 30ml bottle for your conveniece.
