There are many different types of mint, but the healthful benefits of peppermint are typical of this aromatic herb. Peppermint was traditionally known for its ability to relieve indigestion and gastrointestinal distress. After-dinner mints evolved from the ancient custom of concluding feasts with a sprig of mint to soothe the stomach. Now we know that mint contains antioxidants that can help prevent cancer, heart disease and other chronic diseases. The menthol found in mint is a natural ingredient used to treat emphysema, and menthol vapors help relieve congestion.
Peppermint tea is a tonic for bad breath, earache, fever, gallstones, hives, heartburn and nausea.
Don't try ingesting peppermint oil, however. It is highly toxic, even in very small amounts. Spearmint offers many of the same health benefits but is used more often in cooking. The sweet, sharp flavor of this mint is popular in sauces accompanying lamb, and the mint julep is a classic summer drink of the American South. Middle Eastern and Asian cuisines use mint more widely because it complements the pungent spices of Eastern dishes.
