Cornmint Essential Oil

Mentha arvensis

Cornmint Essential Oil


Steam Distilled Cornmint Essential Oil is somewhat similar in aroma and application to that of Peppermint Essential Oil. However, read on for important differences.

Menthol is the component that gives Peppermint and Cornmint Essential Oils their ability to make the areas of application feel cooler or fresher. Spearmint Essential Oil has far less menthol than that of Peppermint or Cornmint.

Menthol doesn't actually cool the skin, but it changes our perception so that we think that the area of application is cooler. [Source: Wikipedia. Accessed: November 5, 2023.]

Cornmint Essential Oil that has not been dementholized can contain up to 80% menthol. In comparison, Peppermint Essential Oil and dementholized Cornmint Essential Oil tends to have a menthol composition that ranges between 30-50%.

Dementholized Cornmint Essential Oil is sometimes passed off as Peppermint Oil, so it is important to be careful of where you procure your oil.

Most Cornmint Oil has been fractionated (dementholized) to remove a large percentage of the menthol. The menthol crystals fractionated from Cornmint Essential Oil are used by personal care manufacturers for use in massage formulations, pain relief blends and other applications that call for menthol.

Pure menthol forms beautiful crystals that are somewhat similar in appearance to that of quartz. Cornmint Essential Oil that has not been dementholized can crystalize at cooler temperatures. If you refrigerate your essential oils (recommended), it's best to allow your Cornmint Essential Oil to warm up before trying to use it.

Therefore, it's especially important to check the GC/MS report and seller's description to learn what the menthol composition is of the Cornmint Essential Oil that you are considering purchasing.

Cornmint Essential Oil is not as widely used within the scope of holistic aromatherapy. Peppermint Essential Oil is preferred for aromatherapy applications.

Within fragrancing, soapmaking and other applications, however, Cornmint can be a practical substitute for Peppermint Essential Oil due to its lower cost.
