Peppermint is an herb that’s a cross between two types of mints: water mint and spearmint. The taste and smell you know from things like candies and soaps come from the concentrated oil (essential oil) inside the plant.
Ancient Greeks, Romans and Egyptians used mints, including peppermint, as medicine thousands of years ago. But peppermint wasn’t recognized as a distinct subspecies until the late 17th century.
How To Use It
You can get peppermint leaf through tea, capsules or as an extract. Peppermint oil comes in capsules and liquids. You can apply it to your skin or take it by mouth. It’s highly concentrated, so only use it with a diluted formula or a few drops at a time. It can be toxic if you take the oil at once.
