Whether it’s triggered by a cold, a sinus infection, allergies or your coworker’s perfume, being stuffed up and congested can make life miserable. Hot peppers to the rescue! Capsaicin -- the plant compound that gives hot peppers their eye-watering zing -- dilates blood vessels in the nose, helping to flush out inflammation and open clogged sinuses even faster than decongestant nasal sprays can, says Teresa Graedon, Ph.D., co-author of The People’s Pharmacy Quick and Handy Home Remedies. Two teaspoons daily is the research-proven dose -- and you can mix them with a bit of food, if you find them tough to swallow on their own. Other great congestion-relievers: 1/4 cup of hot salsa or chili-flavored chutney, or one tablespoon of hot sauce, horseradish or wasabi.
