Mentha pulegium, commonly (European) pennyroyal, also called squaw mint, mosquito plant and pudding grass, is a species of flowering plant in the family Lamiaceae native to Europe, North Africa, and the Middle East. Crushed pennyroyal leaves exhibit a very strong fragrance similar to spearmint. Pennyroyal is a traditional culinary herb, folk remedy, and abortifacient. The essential oil of pennyroyal is used in aromatherapy, and is also high in pulegone, a highly toxic volatile organic compound affecting liver and uterine function.
