Definition
Noun: 1. An essential oil distilled from the leaves of the pennyroyal plant (Mentha pulegium or Hedeoma pulegioides), characterized by a strong, mint-like aroma. It has been used historically in traditional medicine and as a fragrance in products like soaps.
Usage
- Pennyroyal oil is known for its potent, minty scent.

Examples

Advanced Usage
