Have you tried marjoram oil yet? So good! It has awesome calming properties and has a positive and soothing effect on the nervous system. I love the smell too, very unique but
Try it topically in carrier oil pre or post workout massage to help soothe muscles.
Also, from @doterra, try bringing this one to your next yoga class. Add a little to the back of your neck before entering shavasana, for a deeper meditation.
