 American pennyroyal essential oil is obtained from H . pulegioides by steam distillation in approximately 0 . 6 to 1 . 0 % yields . It is a pale - yellow liquid with a much harsher mint - like odor , more bitter and herbaceous than the European oil . The taste is sharp , bitter and slightly burning . 
 It is a pale - yellow - to - yellow , aromatic oil . 
 Depending on the genus , the leaves and flowering tops yield 1 to 2 % pennyroyal oil . The oil contains 80 to 96 % of the cyclohexanone and pulegone . Other constituents of pennyroyal oil include methone , pinene , octanol , piperitenone , limonene , iso - methone and acetic , butyric , salicylic and other acids . 
 The main constituents include l - alpha - pinene , l - limonene , dipentene , 1 - methy - l 3 - cyclo - hexanone , l - menthone , d - isomenthone , acids ( formic , acetic , butyric , salicylic ) and a phenol . Pulegone , the main constituent , is present in lower levels than in the European distilled oil . 
 Pennyroyal ( Hedeoma pulegeoides , Mentha pulegium ) is an example of an extremely toxic herb . The plant is a member of the mint family , Labiatae . The dried leaves and flowering tops of the plant contain from 16 % to 30 % oil , consisting of the monoterpene pulegone . The oil also contains tannins , α - and β - pinenes , other terpenes , long - chain alcohols , piperitenones , and paraffin . 
 The toxicity of pennyroyal is believed to be a result of the pulegone in the oil . Cytochrome P 450 catalyzes the metabolism of pulegone to yield the toxic metabolite menthofuran . Possibly , some of the other terpenes undergo oxidation to active metabolites as well . Menthofuran , metabolites of other terpenes , and pulegone itself deplete hepatic glutathione , resulting in liver failure . This mechanistic hypothesis is supported by the fact that administration of acetylcysteine reverses the toxicity . 
 Pennyroyal has been used as an abortifacient since the time of Pliny the Elder , an insect repellent ( the terpenes in the oil have citronellal - like properties ) , an aid to induce menstruation , and a treatment for the symptoms of premenstrual syndrome . It has also been used as a flea repellent on dogs and cats . When used as an abortifacient , the drug often causes liver failure and hemorrhage , leading to death . Pennyroyal is sometimes used with black cohosh to accelerate the abortifacient effect . Coma and death have been reported . Pennyroyal is an example of an herb that has no safe uses .
