Frequently Asked Questions
How are essential oils aromatherapeutic?
Sara-Chana Silverstein, an aromatherapist and the author of Moodtopia: Tame Your Moods, De-Stress, and Find Balance Using Herbal Remedies, Aromatherapy, and More, said it best: “I don’t think essential oils are going to heal like a Prozac, but they will give people the strength to control their moods more.” While, according to scientific studies, some essential oils like lavender may have the ability to interact with the brain and the nervous system to impact mood and health, essential oils and their aromatherapeutic benefits can’t cure mental health concerns like chronic depression. But, these mood-boosting fragrance oils do have a calming effect that can ease the feel of negative emotions you may be feeling. “Forget the data. If ylang-ylang, which is usually a sexual stimulant, calms you down, then use that to make the association you need,” says Silverstein.
One of the easiest (and most pleasant) ways to achieve these benefits is through aromatherapy, where these concentrated oils are breathed in, allowing them to stimulate the olfactory system in the brain. What’s more, even if you don’t see any magical healing effects from your diffuser, it’s still going to make your space smell sublime (and many of them moonlight as home decor, too).
How do I use an essential oil diffuser?
Most essential oil aroma diffusers require only some water and a few drops of your favorite blend to turn your home or office into a stress-relieving oasis—just make sure you read your device’s instructions (each diffuser functions differently, after all!) pick up some pure essential oils while you’re at it. According to New York City-based acupuncturist, Mila Mintsis, you can tell a brand sells high-quality essential oils if it specifically says it’s considered safe for internal consumption. “It will usually say on the bottle or company’s website, and in this case, you know for a fact that the company guarantees purity and high quality of its oils,” she previously told Allure.
