Try it if: Your symptoms include having a clogged or runny nose.
How it works: When you use a neti pot (sold at drugstores and health-food stores), you pour a warm saline solution (one teaspoon of sea salt per pot of water) into one nostril and allow it to drain out the other nostril. “The rinse removes pollen, dust, or other allergens from your nose before your immune response really kicks in,” says Roberta Lee, vice chair of integrative medicine at the Beth Israel Medical Center, in New York City. Use once or twice daily until symptoms subside.
Good to know: Lean over a sink to catch drips. “At first you may feel a bit uncomfortable,” says Holly Lucille, a naturopathic doctor in Los Angeles.
