To reduce the tickle in your throat, try an astringent gargle -- such as tea that contains tannin -- to tighten the membranes. Or use a thick, viscous gargle made with honey or honey and apple cider vinegar. Seep one tablespoon of raspberry leaves or lemon juice in two cups of hot water; mix with one teaspoon of honey. Let the mixture cool to room temperature before gargling.
If part of the reason you’re breathing through your mouth is because your nose is clogged, use an over-the-counter medicated decongestant nasal spray or drops to open up airways, such as Afrin or Vicks. “Nasal decongestants work well at eliminating congestion in your nose and drying mucus out,” Dr. Abramowitz says. “This can help you feel better and also decrease postnasal drip.”
This natural sweetener may work just as well for a cough as over-the-counter medicines. That could be especially helpful for children who aren’t old enough to take those. But don’t give it to an infant or a toddler younger than 1. There’s a small risk of a rare but serious kind of food poisoning that could be dangerous for them. And while you may have heard that “local” honey can help with allergies, studies don’t back that up.
