Lea Michele uses Thieves oil, a blend of clove, lemon, cinnamon, eucalyptus, and rosemary essential oils, to help create an in-flight oasis.

Lea Michele is that person on a flight. She travels with sheet masks, dandelion tea, an air purifier around her—the whole nine. (See: Lea Michele Shares Her Genius Healthy Travel Tricks)

When we recently caught up with the Glee alum to discuss her partnership with T.J. Maxx–she's joined the brand's Maxx You Project which focuses on embracing change–we asked for all the specifics on her airplane ritual. One thing that stood out? The particular essential oil that she loves for flights: Thieves oil (Buy It, $46, youngliving.com).

Thieves oil is an essential oil blend from Young Living with clove, lemon, cinnamon, eucalyptus, and rosemary essential oils. The combination is inspired by a legend about 15th-century French grave robbers who would use essential oils to protect themselves from diseases. It has a warm, spicy scent that's reminiscent of fall baking, according to the brand.

Beyond simply smelling nice, it might even make you feel better during a flight. Eucalyptus and lemon essential oils are both associated with sinus relief. Plus, the smell of cinnamon oil might help to ease your flight anxiety—research links it to stress and anxiety relief. (If you're wondering how the heck you're supposed to use essential oils, here's a beginners' guide.)

Lea Michele's not the only celebrity who brings Thieves oil onto flights. Jenna Dewan previously told us that she does the same. "If I'm feeling like I'm getting sick or my immune system is at all compromised, I put Thieves oil under my tongue," she said. "I also use it when I travel. On every single plane, I put a little on my finger and I rub it on the air vent to purify the air. I also use it to wash my hands."

Bottom line, if you only copy one part of Lea Michele's travel kit, we say make it the Thieves oil. Anything that smells like baked goods will no doubt go a long way in a farty pressurized cabin.
