(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
In recent years it has become increasingly evident that the toxicity produced by a variety of compounds can be attributed to their metabolites. Simple dose-toxicity studies of a metabolite will help to elucidate its toxic effect, but it is not possible to quantify its role in the toxicity produced
BACKGROUND
Hepatic and neurologic injury developed in two infants after ingestion of mint tea. Examination of the mint plants, from which the teas were brewed, indicated that they contained the toxic agent pennyroyal oil.
METHODS
Sera from each infant were analyzed for the toxic constituents of
Essential oils from mint plants, including peppermint and pennyroyal oils, are used at low levels as flavoring agents in various foods and beverages. Pulegone is a component of these oils. In a 2-year bioassay, oral administration of pulegone slightly increased the urothelial tumor incidence in
