I love to use peppermint and eucalyptus to open up the sinuses and for relieving headaches. And many of my clients love the scent of lavender and lemon which seems to help them relax and “settle into” the massage. I have recently begun questioning the integrity of the oils that I have been using, and have made the switch to buying doTerra oils. I have discussed this with my GP and she advised that I stay away from the blends, but that the single oils are of good quality. Do you know anything about the company and its founders? I have heard they are Mormon and use some of the proceeds for charities.”
