 "(R)-(+)-Pulegone, the major monoterpene component of the abortifacient mint oil, pennyroyal oil, is metabolized by hepatic microsomal monooxygenases of the mouse to a hepatotoxin. The formation of a toxic metabolite is apparently mediated by cytochromes P-450 of the phenobarbital class inasmuch as phenobarbital pretreatment of mice increases, whereas beta-naphthoflavone pretreatment decreases, the extent of hepatic necrosis caused by pulegone. Furthermore, two inhibitors of cytochromes P-450, cobaltous chloride and piperonyl butoxide, block toxicity. An analog of (R)-(+)-pulegone that was labeled with deuterium in the allylic methyl groups was found to be significantly less hepatotoxic than the parent compound. The results indicate that oxidation of an allylic methyl group is required for generation of a hepatotoxic metabolite. Menthofuran was identified as a proximate toxic metabolite of (R)-(+)-pulegone, and investigations with (R)-(+)-pulegone-d6 and 18O2 strongly indicate that menthofuran is formed by a sequence of reactions that involve: 1) oxidation of an allylic methyl group, 2) intramolecular cyclization to form a hemiketal, and 3) dehydration to form the furan." \\

+"Pennyroyal continues to be an herbal toxin of public health importance... We report four cases of pennyroyal ingestion. One patient died, one received N-acetylcysteine, and two ingested minimally toxic amounts of pennyroyal and were not treated with N-acetylcysteine. In the fatal case, postmortem examination of a serum sample, which had been obtained 72 hours after the acute ingestion, identified 18 ng of pulegone per mL and 1 ng of menthofuran per mL. In a serum sample from the patient treated with N-acetylcysteine, which had been obtained 10 hours after ingestion, the menthofuran level was 40 ng/mL.... \\

-"Hydrodistillation of the aerial parts of Mentha pulegium L., collected from the wild and recorded for the first time from different locations in the higher Himalayas, Jammu and Kashmir, India, provided refreshing pale-coloured essential oils with a characteristic minty flavour. Essential oils from different locations were qualitatively similar and were found to be a complex mixture of at least 45 compounds, of which 24 were identified. Eight compounds accounted for about 87-98% of the oil and were characterized as pulegone (65.9-83.1%), menthone (8.3-8.7%), isomenthone (3.8-4.0%), neo-menthol (0.7-1.3%), pulegol acetate (0.1-1.2%), piperitone (1.3-.2%), γ-terpinene (0.9-1.2%), β-caryophyllene (0.1-0.9%) and β-caryophyllene oxide (0.3-1.9%) by capillary GC, GC–MS, 1H-NMR and 13C-NMR." \\
