Peppermint plant Mentha piperita is a perennial herb that is a cultivated hybrid of M. aquatica and M. spicata which are other varieties of the mint family. Mint is naturalised in Europe and North America and is also cultivated throughout the world; more recently the essential oil comes mainly from the USA, although it is also produced in Europe, Russia and Morocco. Production of peppermint mainly occurs for the flavouring and toothpaste industries. Peppermint essential oil has been used as a medicinal and culinary herb for thousands of years, particularly as an infusion for digestive disorders. Peppermint essential oil is a top aromatic note of a strong, fresh, mint aroma with a melting sweet undertone. It blends well with citrus oils, eucalyptus, lavender, lemon and rosemary, and with strongly sweet florals and spices.
