Recent studies support the role of peppermint in many conditions. However, more research is necessary to understand its exact mechanisms and safety.
This article discusses the potential health benefits of peppermint, including their evidence and limitations.
Essential oils
Although research suggests essential oils may have some health benefits, it is important to remember that the Food and Drug Administration (FDA) does not monitor or regulate the purity or quality of these oils.
Also, clinical studies usually use essential oils or other remedies under professional medical guidance. As a result, the same methods may not be appropriate or safe when used at home.
Before using essential oils, supplements, or other home remedies, always make sure to:
- talk with a healthcare professional
- research the quality of a particular brand’s products
- do a patch test before applying them to the skin
- dilute an essential oil with a carrier oil before applying it to the skin
- never swallow essential oils or place them in the mouth, as this can be poisonous

A small 2016 study including people with oral mucositis, a type of mouth inflammation, shared that using chamomile and peppermint mouthwash decreased symptoms and complications.
A 2020 animal study also suggested that peppermint essential oils may help reduce or prevent signs of asthma in mice. However, experts do not usually recommend essential oils for many people with asthma, as they may trigger asthma attacks. More research involving humans is also necessary.
6. Naturally freshens breath

Also, peppermint flavors may help mask unpleasant mouth odors and provide a fresh sensation. The cooling effect of peppermint may also provide a temporary feeling of freshness. Edible peppermint products include peppermint tea, chewing gum, and mints.

- E. coli
- Listeria
- Salmonella
- Staphylococcus
These bacteria can all cause serious infections in humans.
Peppermint may also help prevent or clear fungal infections, such as those caused by Candida fungus strains.
However, peppermint alone may not treat infections — especially if they are serious. Always talk with a doctor if you have questions about treating infection and follow their advice.

Participants who inhaled peppermint oil also reported better moods and reduced mental fatigue after the cognitive tasks.
Further research is necessary
While some studies show the health benefits of peppermint, further research is necessary to confirm its effectiveness for different conditions. Current research is limited, and effects may vary depending on specific circ*mstances, such as how you take peppermint.
Each person may react to peppermint differently, and side effects and allergic reactions can occur.
Always talk with your doctor before using peppermint or other supplements to treat a condition.
Summary
Peppermint has many potential health benefits supported by current research, such as:
- aiding digestion
- relieving headaches and menstrual cramps
- supporting digestion
- improving energy
- freshening breath
However, in many cases, further studies are necessary to confirm the safety and effectiveness of peppermint products.
Always talk with a doctor before using peppermint products or other natural remedies. Also, contact a doctor if you are considering using natural remedies to treat a health condition.
