Both peppermint and spearmint contain menthol, but peppermint has significantly higher menthol content (40%) than spearmint (0.05%). Peppermint contains more menthol because it’s a hybrid of spearmint and watermint–it belongs to both the Mentha genus and Piperita species. Spearmint occurs naturally and belongs to the Spicata species.

Peppermint is often found in over-the-counter balms and rubs to relieve body aches. Apply peppermint oil to your temples and forehead to relieve headaches.

Spearmint leaves also have deeper set veins, and the leaf's edge is slightly more jagged. Peppermint has a distinct purple stem, so peppermint leaves typically have a purple hue. It’s challenging to differentiate spearmint and peppermint solely from appearance, so make sure to taste the leaves to tell the difference.
