When you're on your way to work, and I-77 looks more like a used-car lot than an actual route of travel, try some aromatherapy. That's the practice of smelling -- or rubbing on your skin -- plant-based essential oils. Among their purported attributes, these oils are supposed to help you relax -- something that's hard to do in bumper-to-bumper traffic. Recognizing the stress of the daily commute, some companies have started making essential oil vaporizers that plug right into a car's cigarette lighter. Just put in a few drops of essential oil, buckle your seat belt, and take off on your journey to refreshment. You can find essential oils in most health-food stores, or contact www.naturalhealers.com.
