Meet the Plants | Peppermint

September 5, 2026

Everyone knows mint. It's in the toothpaste, the gum, the mojito, and probably taking over a corner of the garden whether it was invited or not. But long before peppermint ended up in a candy cane, it was doing serious work as one of the most useful medicinal herbs on the planet, with a paper trail going back to at least 1000 BC in Egyptian, Greek, and Roman texts.

Meet Peppermint, Botanically Speaking

Here's the quick rundown:

Latin name: Mentha x piperita
Family: Lamiaceae, identifiable by its square stem and opposite leaves, and shared with rosemary, sage, and basil
Origin: Most mints originate from the Mediterranean and Asia, though some species are native to North and South America, Australia, and South Africa. Today mint is naturalized everywhere.
A hybrid by nature: Peppermint is a natural cross between spearmint and watermint (M. aquatica). That parentage gives it a much higher concentration of menthol than most of its cousins, which is exactly why peppermint largely became the mint of choice in medicine.
The mint family is huge: Over 600 plants answer to the name "mint," all tracing back to just 5 true species: Mentha arvensis, M. aquatica, M. spicata, M. longifolia, and M. suaveolens. Those 5 have interbred into roughly 11 naturally occurring hybrids, and mint hybridizes so readily (in the wild and in cultivation) that different mints planted too close together can eventually blend into one another. Bees cross-pollinate the flowers, and if those cross-pollinated seeds are left to self-sow, the resulting seedlings can be a muddled mix of both parents, distinct scents and flavors folding into something new and hard to trace back to either original. It's part of why gardeners who want to keep their varieties true tend to give each one its own pot, well separated from the rest.
Propagation: Because of that hybridizing, mint seed doesn't reliably breed true to the parent plant. To grow a specific variety, you're taking a root cutting, not planting from seed.
Growth habits: Mint prefers moist soil but will grow practically anywhere, and it's infamous for taking over a garden bed given the chance. Most people keep it contained in a pot for that reason.
A little mint folklore: The word "mint" comes from Minthe, a nymph in Greek mythology turned into a plant after a lover's quarrel. Her lover, feeling a little guilty, made her fragrant instead, so she'd release her scent every time she was stepped on.

Peppermint vs. Spearmint

Spearmint (Mentha spicata) is the gentler of the two mints: sweet, delicate, and the one most often found at the grocery store. Peppermint is more intense, pungent, and almost spicy, with a cooling bite spearmint doesn't have. That's the menthol talking, and it's also what gives peppermint most of its medicinal weight.

In the Kitchen:
Cooking with Peppermint

Mint is one of the most recognizable flavors in the world, showing up in candy, cocktails and liqueurs, cakes, iced tea, jelly, ice cream, and chocolate. It's a complementary ingredient for grain dishes, poultry, and lamb, as well as fruits and vegetables, and it's a natural instant breath freshener, which is exactly why it ended up in toothpaste and chewing gum in the first place.

Ways to enjoy peppermint in the kitchen:

Fresh or dried, steeped into hot or cold tea
Muddled into cocktails and mocktails
Folded into chocolate, ice cream, or baked goods
Whisked into dressings or blended into hummus alongside herbs like parsley or basil
Infused into honey or simple syrup for drinks and desserts, like peppermint hot chocolate or peppermint mocha shortbread cookies
Added to grain salads, roasted vegetables, or lamb dishes for a bright, cooling contrast

The Medicinal Uses of Peppermint

Peppermint's reputation as a digestive herb is well earned, but its uses reach well beyond the stomach.

Peppermint for Digestion

As an aromatic carminative, peppermint helps relax the muscles of the GI tract, easing everyday complaints like gas, bloating, stomach cramps, nausea, vomiting, and diarrhea. It's also shown real promise for more chronic gastrointestinal disorders, including Irritable Bowel Syndrome and Ulcerative Colitis. That same antispasmodic quality is what makes a cup of peppermint tea such a dependable ally after a heavy meal.

Peppermint for Pain and Tension

Menthol's cooling effect makes peppermint a genuinely useful external analgesic. Applied as a poultice at the temples or the base of the neck, it can help ease tension headaches. It's also commonly used on sore or overworked muscles, including menstrual cramps, and can help calm inflammation from insect bites, stings, poison ivy, and itchy skin.

Peppermint for Respiratory and Immune Support

Inhaled, peppermint oil can help clear nasal or sinus congestion. Peppermint also carries antimicrobial properties, showing activity against certain bacteria and fungi, and has long been used to help take the edge off fevers associated with cold and flu by helping to open pores so heat can release more easily. As a mild diuretic, it also supports the body in clearing excess fluid through urine, which can be used for supporting healthy blood pressure levels.

Peppermint for Focus and Energy

Herbalists classify peppermint as a stimulating nervine. Unlike more sedating nervines, it tends to sharpen and energize rather than calm, which makes a cup of peppermint tea a solid, caffeine-free option for cutting through a mid-afternoon slump.

Precautions

Peppermint is generally considered safe for all, especially in culinary amounts. Peppermint oil capsules, though, are a much more concentrated form of peppermint and can genuinely cause problems in excess, especially with preexisting gastrointestinal conditions, so it's worth talking to a licensed practitioner before ingesting peppermint at that concentration.

Peppermint also runs cool and drying by nature. If you already tend toward cold and dry, it may be too much on its own, though pairing it with something moistening like marshmallow root or warming like ginger can help offset that tendency.

Peppermint FAQ

What's the difference between peppermint and spearmint?

Spearmint is milder and sweeter, and the mint most commonly sold at the grocery store. Peppermint is more intense and pungent, thanks to a much higher concentration of menthol, which also gives it most of its medicinal strength.

Is peppermint tea good for digestion?

Yes. Peppermint is one of the most well-documented herbs for digestion, helping relax the GI tract to ease gas, bloating, cramping, and nausea, with research supporting its use for more chronic conditions like IBS as well.

Can peppermint keep me awake at night?

Peppermint is generally classified as a stimulating nervine, so it's often a better fit for a daytime reset than a bedtime cup, especially if you're particularly sensitive. Nonetheless, it's a surprisingly common evening tea, particularly enjoyed after dinner for its digestive benefits. We include a bit of peppermint in our calming, relaxing tea blend Dream Weaver, taking advantage of its ability to help release tension. Paired with relaxing nervines like chamomile and anise hyssop, Dream Weaver is like a deep, unwinding sigh for your nervous system. Like humans, herbs are complex. Regardless, peppermint contains no caffeine.

Is peppermint safe for everyone?

Peppermint is well tolerated by most people in food and tea amounts. The main caution is around concentrated peppermint oil, which should be used carefully and ideally under the guidance of a licensed practitioner, and around peppermint's cooling, drying nature for anyone who already runs cold and dry.
