The herb Pennyroyal (Mentha pulegium, family Lamiaceae), is a member of the mint genus; an essential oil extracted from it is used in aromatherapy. Crushed Pennyroyal leaves and foliage exhibit a very strong spearmint fragrance. Pennyroyal is a traditional folk medicine, poison and abortifacient. This oil is high in pulegone, a highly toxic volatile organic compound, which harms the liver and can stimulate uterine activity.

Uses

Since the U.S. Congress passed the Dietary Supplement Health and Education Act in October 1994, all manufactured forms of pennyroyal have carried a warning label against its use by pregnant women. This substance is not regulated by the FDA.

Pennyroyal essential oil is extremely concentrated, it should not ever be taken internally because it is highly toxic; even in small doses, the poison can lead to death. Complications have been reported from attempts to use the oil for self-induced abortion. In 1978, a pregnant woman was admitted to the hospital two hours after consuming approximately two tablespoonfulls (30 ml) of pennyroyal oil; she subsequently died. The oil can be used for aromatherapy, a bath additive and as a insect repellent. There are numerous studies that show pennyroyal's toxicity to humans and animals.

Pennyroyal tea is the use of a tincture made from the herb, the tincture is widely reputed as safe to ingest in restricted quantities. It has been traditionally employed and reportedly successful as an emmenagogue (menstrual flow stimulant) or as an abortifacient. In 1994 a young woman died from an undetected ectopic pregnancy while performing a self-induced abortion using pennyroyal tea, reports say that she had consumed the tea for longer than the recommended time length of five days.
