answer:Essential oils IMHO are a slippery form of aroma therapy. I blend my own body oils for body and hair that I use at bedtime or after bath and there are specific fragrances that I do believe promote a relaxation response. Lavender, jasmine, chamomile, and sandal wood are my favs. Essential oils are used in bath oils, candles, soaps and some people will put a drop in each nostril to help them chill out. I find using them to be mostly relaxing but I do know if you rub the oils on very vigorously you can “wake up” your skin and feel energized. How you employ them makes all the difference.
