Peppermint For Digestion & Against Nausea

Peppermint is often enjoyed to aid digestion, and sometimes as a remedy for nausea, but what does the science say about these uses?

Peppermint and digestion

In short: it works! (but beware)

Most studies on peppermint and digestion, that have been conducted with humans, have been with regard to IBS, but its efficacy seems quite broad:

❝Peppermint oil is a natural product which affects physiology throughout the gastrointestinal tract, has been used successfully for several clinical disorders, and appears to have a good safety profile.❞

~ Dr. Chumpitazi et al.

However, and this is important: if your digestive problem is GERD, then you may want to skip it:

❝The univariate logistic regression analysis showed the following risk factors: eating 1–2 meals per day (OR = 3.50, 95% CI: 1.75–6.98), everyday consumption of peppermint tea (OR = 2.00, 95% CI: 1.14–3.50), and eating one, big meal in the evening instead of dinner and supper (OR = 1.80, 95% CI: 1.05–3.11).

The multivariate analysis confirmed that frequent peppermint tea consumption was a risk factor (OR = 2.00, 95% CI: 1.08–3.70).❞

~ Dr. Jarosz & Dr. Taraszewska

Peppermint and nausea

Peppermint is also sometimes recommended as a nausea remedy. Does it work?

The answer is: maybe

The thing with nausea is it is a symptom with a lot of possible causes, so effectiveness of remedies may vary. But for example:


Peppermint is useful against wide variety of gastrointestinal disorders, including IBS, but very definitely excluding GERD (in the case of GERD, it may make things worse)

Peppermint may help with nausea, depending on the cause.

Where can I get some?

Peppermint tea, and peppermint oil, you can probably find in your local supermarket (as well as fresh mint leaves, perhaps).
