Oh, Frankincense and Lavender! If I had 3 I would add Cool Azul! HAHA! Frankincense does so many wonders: reduces stress, supports immune system, skin, hormone levels…the list goes on! I need Lavender for calmness! And Cool Azul, well, if you are on an island working, you definitely need something for your sore muscles and tension! I LOVE THEM ALL!
