What is peppermint oil made of?

Peppermint oil is primarily composed of menthol, menthone, and other compounds such as pulegone, limonene, and beta-caryophyllene. It is extracted from the leaves of the peppermint plant (Mentha × piperita) through steam distillation. The oil's distinctive aroma and flavor are mainly attributed to its high menthol content, which also contributes to its cooling sensation. Additionally, peppermint oil contains various other terpenes and alcohols that enhance its therapeutic properties.
