Peppermint (Mentha piperita)
A sharp, cooling single oil prized for its bright minty aroma and refreshing character.
How to use it
3–5 drops brightens a room quickly; blend with lemon for a clean, energizing combination.
Always dilute 1–2% in a carrier oil; keep away from eyes and mucous membranes.
Safety in detail

Every figure above traces to a named table in one of these open-access papers. How this was built →
- Menthol — activates TRPM8, the cold-sensing nerve receptor, producing peppermint's cooling sensation without any real temperature change Andersson et al. (2004), Journal of Neuroscience
A naturally occurring hybrid of watermint and spearmint, first cultivated in 17th-century England.
What the research says
An honest read of the published research — what has actually been studied, at what stage. Not medical advice or a promise of results.
-
Enteric-coated peppermint-oil capsules have been tested in randomized trials for irritable bowel syndrome, with several showing symptom improvement. That is a specific medical formulation — not the same as diffusing or applying the oil.
Cappello et al. (2007), Digestive and Liver Disease -
Peppermint has also been compared with lavender for sleep quality in hospitalized patients — small, single-setting trials rather than broad clinical evidence.
Mahdavikian et al. (2020), Sleep Science and Practice
Evidence & sources
Peer-reviewed research on Peppermint's chemistry and safety. These describe composition and documented effects — not health or treatment claims.
-
Peppermint oil (Mentha × piperita) is characterised chiefly by menthol and menthone, with the menthol/menthone balance shifting by harvest and distillation.
Goudarzian et al. (2020), Journal of Essential Oil Bearing Plants -
Menthol activates TRPM8, the cold- and menthol-sensing nerve receptor — the mechanism behind peppermint's cooling sensation.
Andersson et al. (2004), Journal of Neuroscience
Frequently asked questions
Is peppermint oil safe for babies and young children?
No — keep peppermint and menthol away from the face and nose of infants and young children, because inhaled menthol can trigger breathing problems. Use only well-diluted and never near a small child's face. Final Report on the Safety Assessment of Mentha Piperita (2001), International Journal of Toxicology
Does peppermint oil help with IBS or digestion?
Enteric-coated peppermint-oil capsules have been studied in randomized trials for irritable bowel syndrome with some benefit — but that's a specific swallowed formulation, not diffusing or applying the oil topically. Cappello et al. (2007), Digestive and Liver Disease
Why does peppermint feel cold on the skin?
Its menthol activates TRPM8, the same nerve receptor that senses cold, so your skin registers a cooling sensation even though the temperature hasn't actually changed. Andersson et al. (2004), Journal of Neuroscience
Is peppermint oil phototoxic?
No, peppermint is not phototoxic. But it is potent and cooling — always dilute it for the skin and keep it away from the eyes and sensitive areas.
Gallery
The plant
Peppermint (Mentha piperita) is a naturally occurring hybrid of watermint and spearmint, first cultivated in England in the 17th century and now grown commercially across the world, with the Pacific Northwest of the United States and India among the most significant modern producing regions.
How it’s extracted
Young Living steam-distills the oil from the leaf, and the high menthol content is what gives it that signature icy bite — one of the most recognizable notes in any essential oil collection.
Aroma
Crisp, cooling, and unmistakably minty, sharper and more concentrated than fresh mint leaves or peppermint candy.
Traditional & everyday uses
In the diffuser: 3–5 drops alone brightens a room quickly, or blend with lemon for a clean, energizing combination.
On skin: always dilute before topical use — 1–2% is plenty, since peppermint is potent enough to cause a strong cooling or tingling sensation at higher concentrations. It’s a common note in scalp blends (see our hair growth guide) but should be kept away from the eyes and mucous membranes.
Safety note
Peppermint is not recommended near the face of infants or young children, as the menthol can affect breathing. Read more in our allergy and safety guide.
Sourcing note
Menthol content and aroma vary widely by growing region and distillation care, which is why we point specifically to Young Living rather than a generic “peppermint oil.”
Found in these blends
Peppermint is one of the oils inside 15 Young Living blends.
