Pulegone is a naturally occurring organic compound obtained from the essential oils of a variety of plants such as Nepeta cataria (catnip), Mentha piperita, and pennyroyal.[3][4] It is classified as a monoterpene.

Pulegone is a clear colorless oily liquid and has a pleasant odor similar to pennyroyal, peppermint and camphor. It is used in flavoring agents, in perfumery, and in aromatherapy.

Toxicology[edit]

It was reported that the chemical is toxic to rats if a large quantity is consumed.[5] Asekun et al. found that the chemical content of Mentha longifolia L was decreased by the treatments at high temperatures, suggesting that the herb should be oven dried or thoroughly cooked before consumption.[6]

Pulegone is also an insecticide - the most powerful of 3 insecticides naturally occurring in many mint species.[7]
