The winter holidays are such a feast for the senses: not just our tastebuds, but also our eyes, ears, and olfactory system. This time of year, our public spaces are full of bright lights, festive music, and perfumed everything. Unfortunately, those expensive store-bought candles, diffuser oils, and room sprays are often made with synthetic ingredients that aren’t a healthy choice, no matter how much they promise to imbue us with the spirit of evergreen forests, candy canes, and homemade pumpkin pie. Diffusing natural essential oils—at home, at work, or in your car—is a wonderful alternative to scent your space with seasonal aromas. We love these three time-tested, holiday-inspired, DIY essential oil blends!
