There's no point adding stress to your already stressed-out upper respiratory system, and that's what the change in air pressure will do. Flying with cold or flu congestion can temporarily damage your eardrums as a result of pressure changes during takeoff and landing. If you must fly, use a decongestant and carry a nasal spray with you to use just before takeoff and landing. Chewing gum and swallowing frequently can also help relieve pressure.
Alternatively, make a steam bowl. To do this, fill a large bowl with hot water. Add herbs or essential oils, such as eucalyptus or rosemary, which may also relieve decongestion. Lean over the bowl and place a towel over the head. This traps the steam. Inhale the vapors for 5 minutes. If the steam feels hot on the skin, discontinue until the skin cools down.
Take two enteric-coated peppermint capsules (500 mg each) three times daily. Peppermint kills bacteria that cause bloating and relaxes gastrointestinal muscles for smoother, spasm-free digestion. The enteric coating prevents capsules from opening in the stomach and increasing discomfort by causing heartburn and indigestion. The peppermint releases and goes to work lower in the gastrointestinal tract, where gas-plagued people need it most. (See what your gas is trying to tell you.)
In her recently released book, Alchemy of Herbs: Transform Everyday Ingredients into Foods and Remedies That Heal, Registered Herbalist Rosalee De La Forêt has one mission: to teach readers how to transform everyday ingredients into natural remedies. More plainly put, she wants to show you how to heal your body with foods and ingredients you already have in your kitchen cupboard.
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
