I recently started diffusing essential oils in the home. Not only is it satisfying, it's fun to use. The variety of essential oils is vast and practical. One can get calming, uplifting, cleansing, sensual. It may sound hoaxy. But the oils really can lift the mood or calm the mind (in my experience).
Even as a young child, I never liked the chemical scent of air fresheners. But essential oils are a different story. They are genuine organic oils (by organic, I mean not man made -- but some are certified organic too).
