A Neti Pot is a small, teapot-like device used for nasal irrigation. It helps clear nasal passages by flushing out mucus, allergens, and other debris with a saline solution. This practice can provide relief from sinus congestion, allergies, and colds. To use a Neti Pot, you fill it with a warm saline solution and tilt your head to one side. The solution flows through one nostril and out the other, effectively rinsing the nasal cavity. Regular use can promote better nasal health and improve breathing.
