10 Potent Peppermint Essential Oil Uses for Health

Mentha piperita, or the peppermint plant,  has been used for centuries as a medicinal herb and in cooking.  Peppermint is found in many cleaning products, teas, candies, and stomach medicines today.  Peppermint oil is also steam extracted into essential oil from the leaves for its health benefits.  Experts in essential oils always have this powerful oil on hand.   Here are 10 potent peppermint essential oil uses.  You will most certainly find a use for it right away.

Peppermint Constituents

Peppermint essential oil contains many beneficial compounds.  These include:

  • menthol

Choosing peppermint oil that uses steam distilled and pure guarantees it has only pure peppermint.  Many “natural” oils have chemical solvents in them.

How Does Mint Work (26)?

Because peppermint has many components, it has many actions at play.  Here are a few.

Menthol activates TRPM8: a voltage-gated ion-channel protein : this allows entry of calcium ions on sensing the change in temperature.

Whenever there is a drop in temperature, the voltage on TRPM8 changes so that it allows calcium ions to flow into the nerve cell. This triggers the current to flow from the membrane of the nerve cell and you then sense coolness.

By bringing down the perceived temperature, peppermint helps to bring down inflammation.

Menthol’s pain-relieving and alertness properties are associated with its ability keeping neuronal sodium ion channels healthy as well.

Menthol likely can exert its effects directly on the central nervous system.

  • Asthma

My friend and wise colleague, Calene Van Noy, RD described peppermint well:

One memorable time, Peppermint oil came to the rescue was when my 12 yr old son started dry heaving at Yellowstone while we walked along the boardwalk among the hot-springs that smelled strongly of sulphur.  I was thinking – no way I want my son to throw up amongst all the visitors right on the boardwalk – so I quickly pulled my peppermint out of my handy essential oil key-chain and with a couple breaths of it -he was fine. Phew- disaster averted. We’ve also diverted the car-sickness disaster a few times as well – don’t leave on a car-trip without it!


Research studies use doses of 90 mg or 0.2-0.4 ml of oral peppermint.  Topical peppermint is applied per drop to affected areas.

Certified Pure Therapeutic Grade (CPTG) peppermint essential oil has the following main constituents: menthol, menthone, alpha pinenes and beta pinenes, menthyl acetate, plus many other healthful components. Interestingly, linalool is also rich in lavender, which has calming effects too.  Click here for ways to get CPTG oils.
