While you may have heard that gargling with apple cider vinegar has a similar effect, you should probably steer clear of this tactic for now, says Dr. Comer. “There is little doubt that apple cider vinegar has antibacterial and possibly antifungal properties in lab studies, but whether or not this translates into helping viral or bacterial sore throats is unknown,” he explains. “Additionally, there are potential significant issues to extended use of vinegar with the tooth enamel—vinegar is acidic, and repeated use can damage tooth enamel.”
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.
Believe it or not, your toothbrush may be perpetuating—or even causing—your sore throat. Bacteria collect on the bristles, and any injury to the gums during brushing injects these germs into your system. As soon as you start feeling ill, throw away your toothbrush. Often that’s enough to stop the illness in its tracks. “Changing your toothbrush is often recommended for patients with bacterial throat infections to eliminate the spread of infection,” Dr. Abramowitz says.
Gargle with a small cup of acidic lemon juice to kill odor-causing bacteria. Then eat a bit of plain unsweetened yogurt, which contains beneficial lactobacillus bacteria. These so-called probiotics compete with and replace the reeking bacteria. (They also make you prettier—check it out!) The lemon-yogurt combo instantly neutralizes odor and lasts 12 to 24 hours.
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.
