Bought some peppermint oil at the farmers market in Flagstaff two weeks ago. I use it as a spot treatment for acne and to open up my airway when I sleep. But the biggest change I have seen with it is when I gave some to my friend right before bed who has a severe chronic case of snoring. I didn’t hear a peep from him all night! So we tried it again the next night with the same result. Love this stuff.
