Cayenne pepper can be used as a natural remedy for nosebleeds by helping blood to clot. To use it for a nosebleed, pinch the nostrils for 3-5 minutes while keeping the head upright. Then use a Q-tip coated with cayenne pepper to apply it directly inside the nose at the source of the bleeding. Cayenne pepper's blood-clotting abilities can help stop bleeding from any source. Closing air vents in an unfinished basement, except when the space is in use, can help save power during winter months by preventing warm air from escaping through uninsulated walls.
