This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Peppermint, scientifically known as Mentha piperita, is a hybrid mint, a cross between watermint and spearmint. It is widely recognized for its aromatic properties and is commonly used in culinary, medicinal, and cosmetic applications. Peppermint is valued for its essential oils, which contain menthol, a compound known for its cooling sensation and therapeutic benefits.

Medicinal Uses of Peppermint
Peppermint has been extensively studied for its potential health benefits. It is commonly used in complementary medicine to alleviate symptoms such as nausea, vomiting, and anorexia, particularly in patients undergoing chemotherapy. A study demonstrated that peppermint extract significantly reduced these symptoms in breast cancer patients undergoing chemotherapy, suggesting its efficacy as a supportive treatment1. Additionally, peppermint oil has been investigated for its role in managing irritable bowel syndrome (IBS). While some studies have shown improvements in IBS symptoms with peppermint oil treatment, results have been mixed, indicating the need for further research6 7 10.
Agricultural and Biochemical Attributes
Peppermint is also significant in agriculture due to its essential oil production. Research has shown that nitrogen supplementation can enhance the growth, physiological functioning, and biosynthesis of specialized metabolites in peppermint plants. This optimization can lead to increased essential oil and menthol yield, which are valuable in the global market2. The application of peppermint in aquaculture has also been explored, where dietary peppermint extracts have been shown to improve growth performance and immune parameters in fish species such as Caspian brown trout and Caspian white fish3 5.
Effects on Animal Health
In addition to its use in human health, peppermint has been studied for its effects on animal health. For instance, dietary peppermint extract has been found to improve egg production and quality in laying hens, as well as enhance antioxidant capacity and alter cecal microbiota4. These findings suggest that peppermint can be a beneficial dietary supplement in poultry farming.

Adverse Effects of Peppermint
Mild Adverse Events: In a study on patients with irritable bowel syndrome (IBS), peppermint oil was associated with mild adverse events, although the specifics of these events were not detailed2.
Potential Allergic Reactions: While not explicitly mentioned in the studies, essential oils, including peppermint, can sometimes cause allergic reactions, especially in individuals with sensitivities to plants or essential oils4.
Gastrointestinal Effects: Although peppermint is often used to alleviate gastrointestinal symptoms, it can sometimes cause heartburn or discomfort in some individuals, particularly when consumed in large amounts or in concentrated forms like peppermint oil capsules2.

How has Peppermint Improved Patient Outcomes?
Nausea and Vomiting
Peppermint extract significantly reduced the severity of nausea, vomiting, and anorexia in breast cancer patients undergoing chemotherapy4. Similarly, peppermint oil reduced the frequency and severity of nausea, vomiting, and retching in cancer patients receiving chemotherapy9.
Pain and Sleep Quality
Inhalation of peppermint essence significantly reduced pain and improved sleep quality in patients after open-heart surgery3. This suggests that peppermint can be beneficial in postoperative care to enhance recovery and comfort.
Digestive Health
Peppermint oil has been used to treat irritable bowel syndrome (IBS), showing improvements in abdominal pain, discomfort, and IBS severity, although not significantly different from placebo in some studies2 5 7. Additionally, peppermint drops improved bowel function after cesarean sections by reducing the time to first bowel sounds and gas passage8.
Pressure Injury Prevention
Peppermint gel was effective in preventing pressure injuries in patients with head trauma in neurosurgical ICUs, significantly reducing the incidence rate compared to a placebo10.
Postoperative Recovery
While peppermint essential oil did not significantly reduce nausea severity compared to acupressure, it did improve nausea scores compared to a control group in patients recovering from laparoscopic cholecystectomy1.

Peppermint Mechanisms of Action
Analgesic Mechanisms
Cooling Effect: Peppermint oil, when applied topically, creates a long-lasting cooling sensation by altering calcium channels in cold receptors, which can help alleviate headaches1.
Inhibition of Muscle Contraction: It inhibits serotonin and substance P-induced smooth muscle contractions, contributing to its analgesic properties1.
Increased Blood Flow: Topical application increases skin blood flow, which may also play a role in its pain-relieving effects1.
Neurotoxicity and Contact Toxicity
Pesticidal Action: Peppermint oil exhibits neurotoxic and contact toxic effects against mites, causing dehydration and death through a process of excite-spasm-dehydration-chalasia-die2.
Other Effects
Dysmenorrhea Relief: Peppermint oil has been shown to reduce pain intensity and duration in primary dysmenorrhea, likely due to its analgesic effects mediated by temporary protein receptors4.
IBS Symptom Relief: While peppermint oil did not significantly reduce abdominal pain response in IBS patients compared to placebo, it did improve secondary outcomes like abdominal pain, discomfort, and IBS severity10.

Common Complaints Associated with Peppermint Use
Gastrointestinal Issues: While peppermint oil is often used to alleviate symptoms of irritable bowel syndrome (IBS), it can also cause mild gastrointestinal side effects. In a study, adverse events were more common in patients using peppermint oil, although these were generally mild6.
Skin Reactions: Topical application of peppermint oil can be effective for conditions like chronic pruritus, but it may cause skin irritation in some individuals, especially if not properly diluted1.
Neurological Effects: In the context of nausea and vomiting, peppermint oil’s effects can sometimes be attributed to psychological impacts rather than physiological changes, as seen in a study on nausea and vomiting in pregnancy5.
