Peppermint tea is a naturally sweet, caffeine-free herbal beverage that has been enjoyed for thousands of years. Beyond its refreshing taste, this aromatic tea offers numerous health benefits backed by scientific research, including improved digestion, enhanced mental clarity, and relief from various ailments.
Peppermint (Mentha × piperita) is an aromatic herb in the mint family created from a cross between watermint and spearmint. Native to Europe and Asia, peppermint has been cultivated for its pleasant, cooling flavor and therapeutic properties for millennia.
The leaves of the peppermint plant contain several essential oils, including menthol, menthone, and limonene. Menthol is the primary compound responsible for peppermint’s distinctive cooling sensation and recognizable minty aroma.
While peppermint is commonly used as a flavoring in breath mints, candies, and other foods, many people also consume it as a refreshing tea. Although peppermint tea itself has rarely been studied scientifically, extensive research has been conducted on peppermint oil and extracts, which contain the same beneficial compounds found in the tea.
Here are 12 science-backed benefits of peppermint tea and extracts that may convince you to make this herbal beverage a regular part of your daily routine.
1. May Ease Digestive Issues
One of the most well-known benefits of peppermint is its ability to relieve various digestive complaints, including gas, bloating, and indigestion. The natural compounds in peppermint work to relax the smooth muscles of the digestive system, which can help ease discomfort and prevent painful spasms.
Animal studies have demonstrated that peppermint effectively relaxes the digestive system and may provide pain relief. The herb prevents smooth muscles from contracting excessively, which can relieve spasms throughout the gut.
A comprehensive review of nine studies involving 726 people with irritable bowel syndrome (IBS) found that those treated with peppermint oil for at least two weeks experienced significantly better symptom relief compared to those receiving a placebo. The improvements were notable across various IBS symptoms, including abdominal pain, bloating, and discomfort.
In one clinical trial with 72 IBS patients, participants taking peppermint oil capsules experienced a 40% reduction in symptoms after four weeks, compared to only 24.3% improvement in the placebo group. These results suggest that peppermint’s active compounds have genuine therapeutic effects on digestive health.
Additionally, a review of 14 clinical trials involving nearly 2,000 children found that peppermint reduced the frequency, duration, and severity of abdominal pain. This suggests that peppermint may be beneficial for digestive issues across different age groups.
Research has also shown that the scent of peppermint oil drops can reduce the incidence and severity of nausea and vomiting, particularly in people undergoing chemotherapy. While these studies examined peppermint oil rather than the tea itself, it’s reasonable to conclude that peppermint tea may offer similar digestive benefits due to its content of the same active compounds.
2. May Help Relieve Tension Headaches and Migraines
Peppermint acts as both a muscle relaxant and pain reliever, which makes it potentially effective for reducing certain types of headaches, including tension headaches and migraines.
The menthol found in peppermint oil increases blood flow and provides a cooling sensation that may help ease pain. This dual action can be particularly beneficial for headache sufferers seeking natural relief options.
In a randomized clinical study involving 35 people with migraines, applying peppermint oil to the forehead and temples significantly reduced pain levels after two hours, compared to participants who received a placebo treatment. The pain-relieving effects were substantial and clinically meaningful.
Another study found that administering peppermint oil drops into the nose reduced both the intensity and frequency of headaches. Remarkably, the treatment was found to be as effective as lidocaine, a common pharmaceutical pain reliever, without the side effects associated with medication.
While there is no direct scientific evidence that drinking peppermint tea improves headache symptoms, the aroma of the tea may help relax muscles and provide some relief. For more targeted headache treatment, applying peppermint oil topically to the temples has been proven effective.
3. May Freshen Your Breath
There’s a good reason why peppermint is one of the most popular flavoring agents in toothpastes, mouthwashes, and chewing gums. Beyond its pleasant smell and taste, peppermint possesses natural antibacterial properties that help eliminate germs responsible for dental plaque and bad breath.
In one clinical study, patients who had undergone spine surgery and received a mouth rinse containing peppermint, tea tree, and lemon oils experienced significant improvement in bad breath symptoms compared to those who did not receive the treatment. The antibacterial action of peppermint was likely a key factor in these improvements.
Another study involving female students found that those given a peppermint mouth rinse experienced noticeable improvement in breath freshness after just one week, compared to the control group who did not receive the treatment.
While scientific studies have not specifically examined whether drinking peppermint tea freshens breath, the antibacterial compounds present in the tea are the same ones shown to combat bad breath in other forms. Regular consumption of peppermint tea may therefore help maintain fresher breath throughout the day.
4. May Relieve Clogged Sinuses
Peppermint possesses a powerful combination of antibacterial, antiviral, and anti-inflammatory properties. These therapeutic qualities make peppermint tea potentially helpful for alleviating clogged sinuses caused by infections, the common cold, and seasonal allergies.
Research demonstrates that menthol, one of the primary active compounds in peppermint, improves the perception of airflow through nasal passages. While menthol may not actually increase airflow physically, it creates a sensation that makes breathing feel easier and more comfortable. The steam from hot peppermint tea can enhance this effect, providing soothing relief for congested nasal passages.
Furthermore, studies have shown that warm liquids in general, such as tea and chicken broth, can temporarily improve symptoms of sinus congestion, including runny nose, cough, and sore throat. The combination of warm liquid and peppermint’s menthol content makes peppermint tea particularly beneficial for respiratory comfort.
Though peppermint tea has not been specifically studied for its effects on nasal congestion, the available evidence strongly suggests that sipping warm peppermint tea while inhaling its aromatic steam may provide meaningful relief from sinus discomfort.
5. May Improve Energy Levels
Peppermint tea may be an effective natural way to boost energy levels and reduce feelings of fatigue, all without the caffeine found in coffee or traditional black tea.
While direct research on peppermint tea and energy is limited, studies examining the natural compounds in peppermint have demonstrated beneficial effects on alertness and fatigue reduction.
In one study involving 24 healthy young adults, participants experienced significantly less mental fatigue during cognitive testing when they were given peppermint oil capsules compared to a placebo. The participants reported feeling more alert and focused throughout the testing period.
Another study found that peppermint oil aromatherapy reduced the incidence of fatigue more effectively than a placebo treatment in patients admitted to a cardiology center. The participants who inhaled peppermint oil reported feeling more energized and less exhausted.
These findings suggest that both ingesting and inhaling peppermint compounds may help combat mental and physical fatigue. Drinking peppermint tea allows you to benefit from both routes, as you consume the tea while also inhaling its aromatic steam.
6. May Help Relieve Menstrual Cramps
Because peppermint acts as a natural muscle relaxant, it may provide relief from painful menstrual cramps. The smooth muscle-relaxing properties of peppermint can help reduce the intensity and duration of uterine contractions that cause period pain.
Although peppermint tea specifically has not been studied for menstrual pain relief, research on peppermint compounds has shown promising results. In a study involving 127 women with painful periods, peppermint extract capsules were found to be as effective as non-steroidal anti-inflammatory drugs in reducing both the intensity and duration of menstrual pain.
The women taking peppermint extract reported significant improvements in pain levels without experiencing the potential side effects associated with pharmaceutical pain relievers. This suggests that peppermint offers a natural alternative for managing menstrual discomfort.
While more research is needed to confirm whether drinking peppermint tea provides the same benefits as concentrated peppermint extracts, the muscle-relaxing properties of the tea make it a reasonable option to try for menstrual cramp relief.
7. May Be Beneficial Against Bacterial Infections
While direct research on the antibacterial effects of peppermint tea is limited, peppermint oil has been extensively studied and shown to effectively kill various types of harmful bacteria.
In one study, peppermint oil successfully killed and prevented the growth of common food-borne bacteria, including E. coli, Listeria, and Salmonella, in pineapple and mango juices. This antibacterial action suggests that peppermint could potentially help prevent food poisoning and gastrointestinal infections.
Peppermint oil has also demonstrated effectiveness against several types of bacteria that cause illnesses in humans, including Staphylococcus and bacteria linked to pneumonia. The broad-spectrum antibacterial properties of peppermint make it a valuable natural antimicrobial agent.
Additionally, studies indicate that peppermint reduces several types of bacteria commonly found in the mouth, which contributes to both fresher breath and better oral health. The antibacterial compounds in peppermint work to inhibit bacterial growth and prevent the formation of dental plaque.
Furthermore, menthol has demonstrated antibacterial activity in test-tube studies, confirming that this key peppermint compound plays an important role in fighting bacterial infections.
8. May Improve Your Sleep Quality
Peppermint tea makes an excellent beverage choice before bedtime because it is naturally free of caffeine, unlike traditional black or green teas. This means you can enjoy a soothing cup in the evening without worrying about disrupted sleep.
Additionally, peppermint’s capacity to relax muscles may help you unwind and prepare for sleep. The calming effect of sipping warm tea combined with peppermint’s natural muscle-relaxing properties creates an ideal pre-bedtime ritual.
While scientific evidence specifically linking peppermint tea to improved sleep is limited, one study found that inhaling three drops of peppermint oil per day over a seven-day period improved sleep quality in people with cancer. The participants reported falling asleep more easily and experiencing more restful sleep.
Although more high-quality studies on peppermint’s effects on sleep are needed, the combination of being caffeine-free, having a pleasant taste, and possessing muscle-relaxing properties makes peppermint tea a sensible choice for those seeking better sleep naturally.
9. May Aid Weight Loss Efforts
Peppermint tea is naturally calorie-free and has a pleasantly sweet flavor, which makes it an excellent beverage choice when you’re trying to lose weight or maintain a healthy weight. It can serve as a satisfying alternative to sugary drinks and high-calorie beverages.
While research specifically examining peppermint tea and weight loss is limited, some studies have investigated the effects of peppermint compounds on appetite and metabolism.
In one study involving 13 healthy people, taking a peppermint oil capsule resulted in reduced appetite compared to not taking peppermint. The participants reported feeling less hungry and more satisfied, which could potentially lead to reduced calorie intake throughout the day.
However, the research on peppermint and weight is not entirely consistent. One animal study showed that mice given peppermint extracts actually gained more weight than the control group, though it’s unclear whether these results would translate to humans.
More research is needed to fully understand peppermint’s effects on weight loss. Nevertheless, replacing high-calorie beverages with calorie-free peppermint tea can certainly support weight management goals as part of a balanced diet and healthy lifestyle.
10. May Improve Seasonal Allergy Symptoms
Peppermint contains rosmarinic acid, a beneficial plant compound also found in rosemary and other plants in the mint family. This compound has been linked to reduced symptoms of allergic reactions.
Rosmarinic acid may help alleviate common allergy symptoms such as runny nose, itchy eyes, sneezing, and even asthma-related symptoms. The compound works by reducing inflammation and modulating the immune system’s response to allergens.
In one study involving 29 people with seasonal allergies, those given an oral supplement containing rosmarinic acid for 21 days experienced fewer symptoms of itchy nose, itchy eyes, and other allergy-related complaints than those who received a placebo. The improvements were noticeable and consistent throughout the treatment period.
While it remains unknown whether the amount of rosmarinic acid found naturally in peppermint tea is sufficient to significantly affect allergy symptoms, there is evidence suggesting that peppermint may provide relief. In an animal study, peppermint extract reduced allergic symptoms such as sneezing and itchy nose in rats.
These findings suggest that regular consumption of peppermint tea during allergy season may help reduce the severity of symptoms, though more research in humans is needed to confirm this benefit.
11. May Improve Concentration and Mental Focus
Drinking peppermint tea may help enhance your ability to concentrate, stay alert, and maintain mental focus throughout the day. The natural compounds in peppermint appear to have positive effects on cognitive function.
While studies specifically examining peppermint tea and concentration are not available, two small studies have researched the beneficial effects of peppermint oil on cognitive performance.
In one study, 24 young adults performed significantly better on cognitive tests when they were given peppermint oil capsules compared to a placebo. The participants demonstrated improved accuracy, faster reaction times, and better overall mental performance.
Another study found that simply smelling peppermint oil improved both memory and alertness compared to ylang-ylang, another popular essential oil. The participants who inhaled peppermint reported feeling more awake and mentally sharp.
These findings suggest that the compounds in peppermint can enhance cognitive function through both ingestion and aromatherapy. Drinking peppermint tea allows you to benefit from both methods simultaneously, potentially maximizing the concentration-boosting effects.
12. Easy to Add to Your Daily Diet
One of the best things about peppermint tea is how simple it is to incorporate into your daily routine. The tea is widely available, affordable, and can be prepared in just a few minutes.
You can purchase peppermint tea in convenient tea bags, as loose-leaf tea for a more traditional brewing experience, or you can even grow your own peppermint plants at home. Fresh peppermint is easy to cultivate and can be grown in a garden or in pots indoors.
To make your own fresh peppermint tea:
- Bring 2 cups (473 milliliters) of water to a rolling boil
- Turn off the heat and add a handful of torn fresh peppermint leaves to the hot water
- Cover the container and allow the tea to steep for 5 minutes
- Strain the tea to remove the leaves and enjoy
Because peppermint tea is naturally free of caffeine, you can enjoy it at any time of day without worrying about it interfering with your sleep or causing jitters. Have a cup after meals to aid digestion, in the afternoon to boost your energy levels naturally, or before bed to help you relax and unwind.
The versatility and pleasant taste of peppermint tea make it easy to drink regularly, allowing you to potentially experience its many health benefits as part of your daily wellness routine.
Important Considerations and Precautions
While peppermint tea is generally safe for most people, there are a few considerations to keep in mind. Some individuals may experience heartburn or acid reflux after consuming peppermint, as it can relax the lower esophageal sphincter.
If you have gastroesophageal reflux disease (GERD) or chronic heartburn, you may want to avoid peppermint tea or consult with your healthcare provider before making it a regular part of your diet.
Additionally, if you are pregnant, breastfeeding, or taking any medications, it’s always wise to consult with your doctor before adding herbal teas like peppermint to your routine, as they may interact with certain conditions or treatments.
For most healthy adults, drinking 2-3 cups of peppermint tea per day is considered safe and may provide the various health benefits discussed in this article.
