You put a salt and warm water mixture in something that looks like a little teapot. Then pour it through one nostril and let it drain out the other. You have to practice a little, but once you get the hang of it, it can ease allergy or cold symptoms and may even help you get rid of a cold quicker. Just make sure you use distilled or cooled boiled water and keep your neti pot clean.
Soak feet nightly in 1 part vinegar and 2 parts water to eliminate odoriferous bacteria. Or take a daily foot bath in strong black tea (let it cool first) for 30 minutes. Tea's tannins kill bacteria and close the pores in your feet, keeping feet dry longer; bacteria tend to thrive in moist environments. You'll see results in a few days to a week. One caution: Do the soak only when your feet are free of cuts.
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.”
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.
