During a previous Ask Dr. Oz show , an audience member named Amy, who suffers from sinusitis, bravely demonstrated the use of a nose bidet, or neti pot. Dr. Oz says the device can help clear mucus from your sinuses using warm saltwater. "It's actually filling up those little nooks and crannies that you have and allowing your body to evacuate that stuff so you can actually begin to function normally," he says.

Since then, Amy says she and her husband have used the neti pot every day! "It is fantastic. I have not had one sinus headache. I haven't spent any money on any cold products," she says.

Rachel, a member of the Harpo staff, benefited from the neti pot, too! "It wouldn't be an exaggeration to say that it's been life-changing for me," she says. Rachel is a lifelong allergy sufferer, but since she began using the neti pot, her symptoms have eased up. "I can breathe at night. I'm not blowing my nose, you know, 30 times a day, which is my normal state of being for the last couple years," she says. "So thank you, Dr. Oz, because it was really a huge change for me and I'm very happy."
