Cornmint Essential Oil
Steam Distilled Cornmint Essential Oil can contain up to 80% menthol. However, most Cornmint Oil has been fractionated (dementholized) to remove a large percentage of the menthol. The resulting dementholized oil, therefore, is not commonly used within holistic aromatherapy. Peppermint Oil is preferred for aromatherapy applications.
Within fragrancing and soapmaking applications, however, Cornmint can be a practical substitute for Peppermint Oil due to its lower cost.
Cornmint Essential Oil is sometimes passed off as Peppermint Oil, so it is important to be careful of where you procure your oil.
