The peppermint plant is a hybrid of water mint and spearmint and was first described by Carl Linnaeus in 1753. A high menthol content—like that found in the doTERRA Peppermint essential oil—distinguishes the best quality Peppermint oil from other products. The sharp, sweet scent of Peppermint essential oil can create an exhilarating, stimulating environment during physical activity.
