12 Science-Backed Benefits of Peppermint Tea and Extracts
Peppermint tea is naturally sweet and free of caffeine and calories. It may also be linked to several health benefits and could help improve digestive issues, boost concentration, relieve migraines, and freshen your breath.
Peppermint (Mentha × piperita) is an aromatic herb in the mint family that is a cross between watermint and spearmint (1Trusted Source).
Native to Europe and Asia, it has been used for thousands of years for its pleasant, minty taste and health benefits.
Peppermint is used as a flavoring in breath mints, candies, and other foods. Additionally, many people consume peppermint as a refreshing, caffeine-free tea.
Peppermint leaves contain several essential oils including menthol, menthone, and limonene (2).
Menthol gives peppermint its cooling properties and recognizably minty scent.
While peppermint tea is often drunk for its flavor, it may also have several health benefits. The tea itself has rarely been studied scientifically, but peppermint extracts have.
Here are 12 science-backed benefits of peppermint tea and extracts.
Peppermint may relieve digestive symptoms, such as gas, bloating, and indigestion.
Animal studies indicate that peppermint relaxes your digestive system and may ease pain. It also prevents smooth muscles from contracting, which could relieve spasms in your gut (3Trusted Source).
A 2014 review of nine studies in 726 people with irritable bowel syndrome (IBS) treated with peppermint oil for at least 2 weeks concluded that peppermint provided significantly better symptom relief than a placebo (4Trusted Source).
In one study in 72 people with IBS, peppermint oil capsules reduced IBS symptoms by 40% after 4 weeks, compared to only 24.3% with a placebo (5Trusted Source).
Additionally, in a review of 14 clinical trials in nearly 2,000 children, peppermint reduced the frequency, length, and severity of abdominal pain (6Trusted Source).
Furthermore, another study showed that the scent of peppermint oil drops reduced the incidence of nausea and vomiting and decreased the severity of nausea in people undergoing chemotherapy (7Trusted Source).
While no studies have examined peppermint tea and digestion, it’s possible that the tea could have similar effects.
Peppermint oil has been shown to relax muscles in your digestive system and improve various digestive symptoms. Therefore, peppermint tea may provide similar benefits.
The menthol in peppermint oil increases blood flow and provides a cooling sensation, possibly easing pain (9Trusted Source).
In one 2010 randomized clinical study in 35 people with migraines, peppermint oil applied to the forehead and temples significantly reduced pain after 2 hours, compared to a placebo (10Trusted Source).
Another study found that administering peppermint oil drops into the nose reduced the intensity and frequency of headaches and was as effective as lidocaine, a common pain reliever (11Trusted Source).
While the aroma of peppermint tea may help relax muscles and improve headache pain, there is no supporting scientific evidence to confirm this effect. However, applying peppermint oil to your temples may help.
While no evidence exists that peppermint tea improves headache symptoms, research suggests that peppermint oil reduces tension headaches and migraines.
There’s a reason why peppermint is a common flavoring for toothpastes, mouthwashes, and chewing gums.
In addition to its pleasant smell, peppermint has antibacterial properties that help kill germs that cause dental plaque, which may improve your breath (12Trusted Source).
In one study, people who had undergone spine surgery and had received a rinse made with peppermint, tea tree, and lemon oils experienced improvement in bad breath symptoms compared to those who did not receive the oils (13Trusted Source).
In another 2013 study, female students given a peppermint mouth rinse experienced an improvement in breath after 1 week, compared to the control group (14Trusted Source).
While there is no evidence from scientific studies that drinking peppermint tea has the same effect, the compounds in peppermint have been shown to improve breath.
Peppermint oil has been shown to kill germs that lead to bad breath. Peppermint tea, which contains peppermint oil, may help improve breath as well.
Peppermint has antibacterial, antiviral, and anti-inflammatory properties. Because of this, peppermint tea may alleviate clogged sinuses due to infections, the common cold, and allergies (15Trusted Source).
Additionally, some older research demonstrates that menthol — one of the active compounds in peppermint — improves the perception of airflow in your nasal cavity. Therefore, steam from peppermint tea may help you feel as though your breathing is easier (16Trusted Source).
Furthermore, warm liquids, such as chicken brothand tea, have been shown to temporarily improve symptoms of sinus congestion such as a runny nose, cough, and sore throat in some older studies (17Trusted Source).
Though peppermint tea has not been studied for its effects on nasal congestion, evidence suggests that it may be helpful.
While there is limited evidence that drinking peppermint tea may help unclog your sinuses, a warm beverage containing menthol — such as peppermint tea — may help you breathe a little easier.
Peppermint tea may improve energy levels and reduce fatigue.
While there are no studies on peppermint tea specifically, research demonstrates that natural compounds in peppermint may have beneficial effects on energy.
In another study, peppermint oil aromatherapy was found to reduce the incidence of fatigue more effectively than a placebo in people admitted to a cardiology center (19Trusted Source).
Peppermint oil has been shown to relieve mental and physical fatigue in some studies, but research specifically on peppermint tea is lacking.
While peppermint tea has not been studied to that effect, compounds in peppermint have been shown to improve symptoms.
In one study in 127 females with painful periods, peppermint extract capsules were found to be as effective as a non-steroidal anti-inflammatory drug in reducing the intensity and duration of pain (20Trusted Source).
Though additional research is needed, it is possible that peppermint tea could have similar effects.
Drinking peppermint tea may reduce the intensity and length of menstrual cramps since peppermint helps prevent muscle contractions. However, more research is needed.
While there are no studies on the antibacterial effects of peppermint tea, peppermint oil has been shown to effectively kill bacteria (21).
Peppermint oil also kills several types of bacteria that lead to illnesses in humans, including Staphylococcus and pneumonia-linked bacteria (23Trusted Source).
Additionally, studies indicate that peppermint reduces several types of bacteria commonly found in your mouth (12Trusted Source).
Furthermore, menthol has also demonstrated antibacterial activity in some older test-tube studies (24Trusted Source).
Studies confirm that peppermint effectively inhibits several types of bacteria, including those that cause food-borne illnesses and contagious illnesses
Peppermint tea is an ideal choice before bed, as it’s naturally caffeine-free.
What’s more, peppermint’s capacity as a muscle relaxant may help you relax before bedtime (15Trusted Source).
That said, there is not much scientific evidence that peppermint enhances sleep.
However, one study found that inhaling three drops of peppermint oil per day over a 7-day period improved sleep quality in people with cancer (25Trusted Source).
Still, more high quality studies on the effects of peppermint on sleep are needed.
Little scientific evidence suggests that peppermint tea is beneficial for sleep. However, it’s a caffeine-free beverage that may help you relax before bedtime.
Peppermint tea is naturally calorie-free and has a pleasantly sweet flavor, which makes it a smart choice when you’re trying to lose weight.
However, there is not much research on the effects of peppermint tea on weight.
On the other hand, an animal study showed that mice given peppermint extracts gained more weight than the control group (27Trusted Source).
Therefore, more research is needed on peppermint and weight loss.
Peppermint tea is a calorie-free beverage that may help satisfy your sweet tooth and reduce your appetite. However, more studies on peppermint and weight loss are needed.
Rosmarinic acid is linked to reduced symptoms of allergic reactions, such as runny nose, itchy eyes, and asthma (29).
In one 2004 study in 29 people with seasonal allergies, those given an oral supplement containing rosmarinic acid for 21 days had fewer symptoms of itchy nose, itchy eyes, and other symptoms than those given a placebo (30Trusted Source).
While it’s unknown whether the amount of rosmarinic acid found in peppermint is enough to affect allergy symptoms, there is some evidence that peppermint may relieve allergies.
In fact, in one older study in rats, peppermint extract reduced allergic symptoms, such as sneezing and itchy nose (31Trusted Source).
Peppermint contains rosmarinic acid, which has been shown to reduce allergy symptoms, such as sneezing and runny nose. However, evidence on the efficacy of peppermint tea against allergy symptoms is limited.
Drinking peppermint tea may help improve your ability to concentrate and focus.
While studies on the effects of peppermint tea on concentration are unavailable, two small studies have researched this beneficial effect of peppermint oil, taken by ingestion or inhalation.
In one study, 24 young adults performed significantly better on cognitive tests when they were given peppermint oil capsules (18Trusted Source).
Peppermint oil, found in peppermint tea, may help increase alertness and memory, which may
