Cinnamon is good for so many things besides making Snickerdoodle Cookies, etc. If you have the sniffles, it can be used to make cinnamon tea to relieve congestion. It also helps ease diarrhea and nausea, and it helps to metabolize fats. All you have to do is make the tea with one teaspoon cinnamon, one cup boiling water, and let steep for 15 minutes. However, women who are pregnant should not use large amounts of cinnamon.
