5 Surprising Peppermint Benefits + How To Use It

by Skye Macfarlane on Apr 17, 2026 0 comments

Peppermint is one of those herbs that everyone is familiar with. You can find it in your chewing gum, your tea, your toothpaste… so it can be easy to forget that this plant has some amazing medicinal properties, beyond breath freshening. Peppermint benefits your digestive system, nervous system, and airways, and it can even affect how your brain perceives breathing. Pretty impressive for such a small plant.

What is peppermint?

Peppermint (Mentha x piperita) is a hybrid, meaning a cross between spearmint and water mint. That hybrid is what gives it its high menthol content, which is the compound responsible for that intense cooling effect and many of its functional actions in your body.

Peppermint is sharp, cooling, and has a higher amount of menthol, making it more therapeutic.

Spearmint is sweeter, softer, and more like chewing gum, but can also be utilised in clinical herbal medicine, particularly for polycystic ovary syndrome (PCOS).

Mint is a general term given to the whole plant family.

5 benefits of peppermint

1. Digestion

You know that feeling after a big meal: extra full, tight, uncomfortable? That is due to a mix of slowed gastric emptying, mild gut spasms and pressure that can occur from gas or fermentation. Peppermint (specifically menthol) acts as an antispasmodic. This means it can help relax smooth muscle in the digestive tract, reduce cramping, allow trapped gas to move freely and ultimately help improve the flow of digestion. There’s solid clinical evidence here, especially in IBS, where peppermint oil has been shown to reduce symptoms such as pain and bloating.

Peppermint doesn’t make you digest food faster; it helps to make digestion feel smoother and less uncomfortable. When you feel bloated, it is not just gas; it is also how your gut senses pressure. Peppermint has been shown to reduce visceral hypersensitivity (basically, how strongly your gut reacts to normal stretching). So the same amount of gas can occur, but with less discomfort - another example of peppermint benefits in action.

2. Oral health

Peppermint freshens your breath and gives you that clean, cooling feeling. But it’s not just masking bad breath; it’s actively working on it. Its natural compounds have antimicrobial activity, which can help reduce the bacteria linked to odour and oral imbalance - one of the lesser-known peppermint benefits beyond digestion.

This is very helpful for sore teeth and also gum health, as it activates cold receptors while reducing pain signalling. It can help create a soothing sensation, which can give immediate relief to an annoying sore or tickly throat. This is why we use peppermint in our Throat Spray.

3. Sinus comfort and breathing

This one surprises people. While peppermint doesn’t physically open your airways, it does activate cold receptors in your nose and throat that make it feel like airflow has improved, so your brain interprets breathing as easier. And when your body thinks breathing is easier, it relaxes breathing patterns, which improves comfort. This is why peppermint is so commonly used when you feel congested, run-down, or heavy-headed.

4. Nausea

Peppermint has long been used for nausea, but what’s interesting is that it can work even through smell alone. Some studies show inhaled peppermint can reduce nausea, meaning it works through both digestive and sensory pathways. Peppermint interacts with your gut, vagus nerve and your brain’s nausea centres. Menthol’s cooling effect and aroma can help modulate your sensory signals, reduce the feeling of nausea, and help to interrupt the ‘I think I am going to be sick’ feedback loop.

5. Mental clarity

Peppermint sits in that perfect middle ground when it comes to mental clarity because it is not sedating, nor is it overstimulating. Instead, it helps create a clearer head, helps to reduce mental fatigue and provides a subtle sense of alertness. So, clarity without caffeine.

Different ways to use peppermint

Here are some different ways you can utilise peppermint benefits at home.

Digestive discomfort - After a rich meal, peppermint tea is a great way to ease bloating and discomfort. It's also great because it works very quickly.

Mid-afternoon slump - Peppermint (tea or even its aroma) can be used for a mental reset without caffeine.

Travelling or feeling queasy - Peppermint can be used for nausea support (even just the smell can help).

Breath freshening - After coffee or food, using peppermint for breath and oral freshness can really help.

When you feel congested or “head heavy”, using peppermint can create that clear, open feeling.

Different forms matter too:

Taking peppermint as a tea is a great, gentle, daily way to support your health, as it’s easy to do and widely accessible.
Capsules provide targeted digestive support for really upset stomachs.
Sprays that contain peppermint are amazing for the throat, breath and upper respiratory system.
Aromatic use is a fast sensory way of feeling a bit more ‘awake’.
Peppermint oil, topically, can be really helpful for headaches or migraines, as the same cooling mechanism can help disrupt pain signalling.
