The main oils of the Mentha genus that have achieved high economic importance are
cornmint, peppermint, Native spearmint, and Scotch spearmint; however, two other oils
Mentha citrata and pennyroyal are of commercial importance but to a much lesser extent.
The oil compositions of each of these six mint oils are examined separately in the order
Mentha citrata, cornmint, peppermint, pennyroyal Native spearmint, and Scotch spearmint.
A brief discussion on the cultivation and oil production precedes the review of the oil
compositions of these commercially important mints.
