Peppermint can help with digestive issues such as gas, bloating, and indigestion. According to animal research, peppermint soothes the digestive tract and may relieve discomfort. It also stops smooth muscles from tightening, which may help reduce stomach spasms. A meta-analysis of nine trials including 926 persons with irritable bowel syndrome (IBS) who were given peppermint oil for at least two weeks found that it gave considerably greater symptom alleviation than a placebo.

Peppermint oil capsules improved IBS symptoms by 40% after four weeks in one trial of 72 persons with IBS, compared to only 24.3 percent with a placebo. In addition, peppermint lowered the incidence, duration, and intensity of stomach discomfort in 14 clinical studies involving approximately 2,000 children. Furthermore, in a trial of 200 persons undergoing chemotherapy for cancer, peppermint oil capsules lowered the occurrence and intensity of nausea and vomiting. While no research on peppermint tea and digestion has been conducted, the drink may have comparable benefits.

Peppermint, which serves as a muscle relaxant and pain reliever, may alleviate certain forms of headaches. Peppermint oil contains menthol, which improves blood flow and creates a cooling feeling, perhaps alleviating pain. Peppermint oil applied to the forehead and temples significantly decreased pain after two hours in one randomized clinical investigation of 35 migraine sufferers compared to a placebo oil.

In another trial of 41 persons, peppermint oil applied to the forehead was shown to be as helpful as 1,000 mg of acetaminophen for headaches. While the scent of peppermint tea may help relax muscles and alleviate headache discomfort, there is no scientific proof to back this claim. Applying peppermint oil to your temples, on the other hand, may assist.

Peppermint is a popular flavor for toothpaste, mouthwashes, and chewing gum for a reason. In addition to its pleasant odor, peppermint contains antibacterial capabilities that aid in the killing of microorganisms that create dental plaque – which may help freshen your breath. In one research, persons who had spine surgery and had a rinse including peppermint, tea tree, and lemon oils reported better breath symptoms than those who did not get the oils.

In another research, schoolgirls given a peppermint mouth rinse had better breath after one week than the control group. While there is no scientific proof that drinking peppermint tea has the same impact, peppermint components have been demonstrated to enhance breath.

Peppermint possesses antibacterial, antiviral, and analgesic effects. As a result, peppermint tea may help to clear congested sinuses caused by infections, the common cold, and allergies. Furthermore, studies show that menthol, one of the active chemicals in peppermint, increases the sense of airflow in the nasal cavity. As a result, the steam from peppermint tea may make you feel as if your breathing is easier.

Warm drinks, such as chicken broth and tea, have also been reported to temporarily alleviate nasal congestion symptoms, most likely because of their vapors. Though the benefits of peppermint tea on nasal congestion have not been explored, evidence suggests that it may be beneficial.

Peppermint tea may boost energy levels and minimize weariness during the day. While no trials on peppermint tea have been conducted, research indicates that natural chemicals in peppermint may have energy-boosting properties. In one study, 24 healthy young people who were given peppermint oil capsules felt less fatigued during a cognitive test. Another study discovered that aromatherapy with peppermint oil reduced the prevalence of daytime drowsiness.

Menstrual cramps may be relieved by peppermint since it serves as a muscle relaxant. While peppermint tea has not been investigated in this regard, peppermint components have been demonstrated to alleviate symptoms. Peppermint extract capsules were shown to be equally efficient as a nonsteroidal anti-inflammatory medicine in lowering the intensity and duration of pain in one research of 127 women with uncomfortable periods. It's probable that peppermint tea will have the same effect.

While no research on the antibacterial benefits of peppermint tea has been conducted, peppermint oil has been demonstrated to successfully destroy germs. Peppermint oil was proven to kill and inhibit the growth of common food-borne germs such as E. coli, Listeria, and Salmonella in pineapple and mango juices in one research. Peppermint oil also destroys germs that cause infections in people, such as Staphylococcus and pneumonia-linked bacteria. Furthermore, research shows that peppermint decreases numerous types of germs often present in the mouth. Menthol has also been shown to have antimicrobial properties.

Because it has no caffeine, peppermint tea is an excellent choice before bed. Furthermore, peppermint's ability to relax muscles may help you relax before night. However, there is little scientific evidence that peppermint improves sleep. In one research, peppermint oil increased the number of time mice spent sleeping after being administered a sedative. However, another study discovered that menthol had no sedative effect. As a result, research on peppermint and sleep is conflicting.

Rosmarinic acid, a plant chemical found in rosemary and plants in the mint family, is present in peppermint. Rosmarinic acid has been related to a reduction in allergic response symptoms such as runny nose, itchy eyes, and asthma. In a randomized 21-day trial of 29 adults with seasonal allergies, those who took an oral supplement containing rosmarinic acid reported fewer symptoms of itchy nose, itchy eyes, and other symptoms than those who took a placebo.

While it is uncertain if the quantity of rosmarinic acid present in peppermint is sufficient to impact allergy symptoms, there is some evidence that peppermint may alleviate allergy symptoms. In mouse research, peppermint extract decreased allergy symptoms including sneezing and itching nose.

Peppermint tea is naturally calorie-free and has a delightfully sweet flavor, making it an excellent choice for weight loss. However, there haven't been a lot of studies done on the effects of peppermint tea on weight loss. A short research of 13 healthy persons found that ingesting a peppermint oil capsule lowered hunger compared to not taking peppermint. Animal research, on the other hand, found that mice fed peppermint extracts acquired more weight than the control group. More study on peppermint and weight reduction is required.

Drinking peppermint tea may help you concentrate and focus better. While no studies on the benefits of peppermint tea on focus are known, two brief studies on the positive impact of peppermint oil — taken orally or inhaled — have been conducted. In one study, 24 young, healthy participants who were given peppermint oil capsules fared much better on cognitive tests. Another study indicated that sniffing peppermint oil improved memory and alertness more than ylang-ylang, another popular essential oil.
