The essential oil of pennyroyal is considered toxic. Death has been reported after the consumption of small amounts. A characteristic noted in most cases of pennyroyal overdose is a strong minty smell on the patient's breath.
A possible role for N- acetylcysteine (NAC) in the management of pennyroyal overdose has been suggested. However, this application has not been confirmed by animal or human studies.
The essential oil of pennyroyal may act as an emmenagogue (menstrual flow stimulant) and induce abortion. However, it may do so at lethal or near- lethal doses, making this action unpredictable and dangerous. Future research to determine the safety and efficacy of the less toxic parts of the pennyroyal plant on the menstrual cycle is needed before a recommendation can be made.
