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.
It was reported that the chemical is toxic to rats if a large quantity is consumed.[5][6]
Pulegone is also an insecticide − the most powerful of three insecticides naturally occurring in many mint species.[7]
As of October 2018, the FDA withdrew authorization for the use of pulegone as a synthetic flavoring substance for use in food, but that naturally-occurring pulegone can continue to be used.[8]
