Is Peppermint Tea Good for Cortisol?

Partly—peppermint tea may help you unwind as part of a calming routine, but it is not proven to lower cortisol. A cup of peppermint tea can be a pleasant caffeine-free choice when made from peppermint alone. It should not replace evaluation or treatment for high cortisol.

Can peppermint tea lower cortisol?

There is no reliable clinical evidence that peppermint tea lowers cortisol in people. Enjoying it during a quiet break may help you feel more relaxed, but feeling calmer does not establish that your cortisol level has changed.

Cortisol is a hormone involved in the body’s response to stress. It also helps regulate processes such as blood sugar and metabolism. Its level normally changes throughout the day, so one feeling or symptom cannot tell you whether it is high.

If you are looking at the best drinks for high cortisol, treat peppermint tea as a comforting beverage rather than a way to correct an abnormal hormone level. A clinician can help determine whether testing or follow-up is appropriate.

How might peppermint tea help you relax?

The potential benefit is the routine, not an established cortisol-lowering action of peppermint. Pausing, sitting comfortably and drinking something warm may give you an opportunity to slow down during a stressful day. The taste and aroma may also make that break more enjoyable if you like peppermint.

Plain peppermint tea is naturally caffeine-free. Choosing it instead of a caffeinated drink may be useful if caffeine makes you feel jittery or interferes with your sleep. Check the label on blends: peppermint combined with black or green tea can contain caffeine.

Relaxation and cortisol are related to the body’s stress response, but they are not interchangeable measurements. A soothing cup does not necessarily change cortisol enough to affect a test result or a medical condition.

What does the evidence say about peppermint tea and cortisol?

There are no studies provided that establish an effect of peppermint tea on cortisol. That means there is no reliable basis for recommending a particular amount, brewing strength or schedule to lower it.

Evidence about other peppermint preparations would not automatically apply to peppermint tea. Peppermint oil, concentrated extracts and peppermint aroma differ from a brewed beverage in what people are exposed to and how they use it. Results from laboratory or animal research would also need to be confirmed in people before they could support a health claim.

Similarly, a report that someone feels less stressed after drinking peppermint tea would not by itself show that their cortisol fell. To answer that question, researchers would need to measure cortisol in an appropriate human study. For now, enjoy peppermint tea for its flavor or as a routine you find relaxing, not for a proven hormone effect.

How can you use peppermint tea safely?

Choose a plain peppermint tea bag or a product labeled as peppermint herbal tea, and prepare it according to the package directions. Let it cool enough to drink comfortably. If you prefer a blend, check its ingredients for caffeine or other herbs you may need to avoid.

You can include peppermint tea in a break that also makes room for activities you find calming, such as taking a walk or putting your phone away. There is no established time of day when peppermint tea is more effective for cortisol, so choose a time that suits you.

There is also no established dose for lowering cortisol. More or stronger tea has not been shown to produce a greater hormone benefit. If it causes discomfort, stop drinking it and ask a healthcare professional for advice.

Who should be careful, and when should you see a doctor?

Peppermint may aggravate heartburn or reflux in some people. If you have gastroesophageal reflux disease (GERD), notice symptoms after drinking peppermint tea, or have a gallbladder condition, ask a healthcare professional whether it is suitable for you.

If you are pregnant or breastfeeding, or want to give peppermint tea regularly to a child, check with a clinician first; safety information for regular medicinal use is limited. If you take medication, ask a pharmacist or clinician about your circumstances, especially before using concentrated peppermint products. Do not stop or change prescribed medication to try peppermint tea.

See a clinician if you have a high cortisol test result or concerns such as unexplained weight gain around the trunk, easy bruising, wide purple stretch marks or increasing muscle weakness. These signs can have different causes and need assessment rather than self-diagnosis. If you take corticosteroid medication, tell your clinician and do not stop it abruptly.
