I have always burned incense around the house but recently decided to kick that as that was the last thread tying me to combustion. I'm using my Underdog aromatherapy cup for the first time and all I have is cedar wood e.o. which smells great but I'm going to try some others in the near future. What's your favorite e.o. or e.o. blends to use in your vape's aromatherapy cup around the house?
