Oil of pennyroyal, derived from the Mentha pulegium plant, is a potent essential oil with a strong, minty aroma. It contains pulegone, a monoterpene ketone, which is responsible for its characteristic scent and potential medicinal properties. Historically used for respiratory issues and digestive problems, it is now recognized for its potential toxicity, particularly when ingested, and is not recommended for internal use. The oil's strong scent and potential health risks have led to its classification as a hazardous substance, with warnings against ingestion and proper handling to prevent adverse effects.
