mix the essential oils with 1 tablespoon of base carrier oil before

Support your head on a bath pillow or a rolled up towel and close your eyes and inhale. Concentrate on your breathing and empty your mind of worries. the therapeutic properties of the essential oils will soothe away your stress. After 15-20 minutes, emerge relaxed and wrap yourself in a large warm towel.
