Peppermint is a cooling herb best known for its active compound menthol. It has some of the strongest clinical evidence in the herb category: enteric-coated peppermint oil is well-supported for IBS, and topical application rivals over-the-counter options for tension headaches. Use it diluted and keep it away from young children.

Works For
| Use | Strength | What the evidence says |
|---|---|---|
| IBS symptoms | ●●●●○ | Cochrane review and meta-analyses support enteric-coated peppermint oil for abdominal pain, bloating, and overall IBS symptom severity |
| Tension headaches | ●●●●○ | Topical peppermint oil (with ethanol) comparable to acetaminophen in several RCTs (Gobel et al., Cephalalgia) |
| Nausea | ●●●○○ | Positive results in some aromatherapy trials (post-op and chemo nausea); evidence mixed overall |
| Nasal congestion | ●●○○○ | Menthol creates a sensation of increased airflow but may not increase objective nasal patency |
| Antimicrobial (lab) | ●●○○○ | Active against several bacteria and fungi in vitro; meaningful human trial data is limited |
Forms & Preparations
| Peppermint tea | Steep dried leaves 5–10 min; gentle for everyday digestion and relaxation |
|---|---|
| Essential oil (topical) | Always dilute in a carrier oil (e.g. jojoba, coconut) before skin contact; for temples and neck tension |
| Enteric-coated capsules | Specifically for IBS; enteric coating bypasses the stomach and prevents reflux side effects |
| Fresh leaves | Add to water, smoothies, or salads; gentle culinary use |
| Aromatherapy / inhaled | A few drops on a tissue or in a diffuser; for nausea and stuffiness |
About Peppermint
Peppermint (Mentha piperita) is a hybrid herb cultivated for its high menthol content. Menthol activates cold-sensitive receptors (TRPM8 channels) in the skin and mucous membranes, producing the characteristic cooling sensation without actually lowering temperature.
Its strongest clinical evidence is for IBS: a Cochrane review and several meta-analyses conclude that enteric-coated peppermint oil capsules meaningfully reduce abdominal pain and global IBS symptoms compared to placebo. The enteric coating matters because it allows the oil to reach the intestines intact instead of being absorbed in the stomach (which also prevents the common side effect of heartburn).
For tension headaches, a topical formulation of peppermint oil in ethanol applied to the forehead and temples has shown efficacy comparable to acetaminophen in randomized trials. Peppermint oil is on the FDA's "generally recognized as safe" (GRAS) list at culinary amounts, and the NIH NCCIH classifies it as having some positive evidence for IBS and headache.
