Spearmint
(Mentha Spicata)

Also called Pennyroyal (not to be confused with European Pennyroyal - see warning below). Hardy perennial that will grow to about 24 inches high. Has aromatherapeutic properties, as well as making a great seasoning and tea. Prefers moist soil and full sun.

A slightly less potent variety than peppermint, this strain is carminative (medication that prevents the formation of gas in the alimentary tract or eases its passing). Taken after dinner, it aids digestion and relieves flatulence.

Warning: Do not pick wild - use only identified mints. European Pennyroyal, a close cousin, has been known to induce comas and convulsions.
