Several studies show breathing in essential oils could benefit your health—but only if done right.
Essential oils have grown into a $1.5 billion business. The plant-extracted, highly concentrated oils have historically been used in beauty and cleaning products—but now research proves that when inhaled properly, they can also be beneficial to ones health, says Brent Bauer, M.D., Director of the Complementary and Integrative Medicine program at the Mayo Clinic.
Studies have found that essential oils can both protect your long-term health and alleviate symptoms of common ailments. They can help in decreasing stress levels, easing pain, enhancing mood, increasing energy, decrease cravings and help nausea. Essential oils have also been shown to kill flu, E. coli, and cancer cells.
The uses of essential oils and aromatherapy come with a warning however, "Whatever is powerful enough to exert a beneficial effect in the body is powerful enough to exert a negative effect," says Bauer. Essential oils release volatile organic compounds (VOCs), off-gases often linked to paints and pesticides. (Some VOCs are more hazardous than others, and "volatile" just means a substance can evaporate.) So while, for instance, moderate exposure to essential oils can be heart-healthy, prolonged exposure can pose cardiac risks.
The key is staying within a 15-to 60-minute sweet spot—never breathe in essential oils for more than one hour at a time. Always follow the instructions on the bottle, and if you are taking any medications or suffer from a chronic health condition, ask your doctor before you start practicing aromatherapy. Just as with any other medicine, essential oils must be used correctly to yield huge health rewards.
Before You Buy...
Follow these tips to make sure you purchase genuine products:
- Beware the blanket aromatherapy label, often slapped on diluted oils laced with synthetic fragrances.
- Look for 100 percent pure and organic oils free of fillers, pesticides, and synthetic chemicals.
- If a label says therapeutic grade or steam distilled, even better.
- Most essential oils have long shelf lives—more than a year if stored in a cool, dry place.
A diffuser is the most effective way to unleash essential oils into the air, but if you don't have one (they run from $25 to $200), you can drip oil into a bowl of steaming hot water. In either case, use one or two drops of one oil at a time. Stand a few feet away and take 10 deep breaths, then breathe normally. If you stick within the safe time limit and open a window when you're done, you can practice aromatherapy every day. Aromatherapy is not for everyone, and a no-no if you're pregnant, so check with your doctor to see if aromatherapy is right for you before you begin.
