What are the benefits of mint?
Mint cools, calms the digestion, and gently lifts the mind — one of Persia's most loved everyday remedies.
Peppermint (Mentha piperita) and spearmint (Mentha spicata) are among the best-studied herbs for irritable bowel syndrome, and both show promise for tension headache and mental freshness. In Persia, nāʿnāʿ is part of daily life — in tea, salads, and yogurt drinks.

What the studies found›
Spearmint tea has improved cognitive scores in older adults.
How our understanding evolved
- Ancient Egypt
Mint mentioned in the Ebers Papyrus for digestive complaints, among the oldest medical texts known.
- Classical Greece
Mint's name traced to the myth of the nymph Minthe; the plant becomes a staple flavoring and digestive aid.
- Classical and medieval Persia
Mint enters daily food and medicine as a 'cooling' herb, used in yogurt drinks, soups, and tea.
- 1970s–1980s, enteric-coated capsule development
Researchers develop delayed-release peppermint oil capsules designed to reach the intestine intact, avoiding stomach irritation.
- 2014, Khanna et al. meta-analysis
A pooled analysis of trials confirms enteric-coated peppermint oil eases IBS symptoms more than placebo.
- Today
Mint remains both a kitchen staple worldwide and a studied treatment specifically for IBS and tension headache.
What does the research say?
Overall strength of the research behind this answer: Moderate Research. The detail lives in the sections below — jump straight to the part you need.
Background: what it is and why it matters›
The leaves of Mentha plants — used fresh, dried, as tea, and as a special enteric-coated oil capsule for IBS.
Peppermint is itself a natural hybrid of spearmint and water mint, while spearmint is a distinct species with its own, gentler aromatic profile.
Menthol, mint's signature cooling compound, is what activates the same skin and mouth receptors responsible for the sensation of coolness.
It offers dependable relief for IBS bloating and cramping, plus a gentle lift for focus.
Because it works through smooth-muscle relaxation in the gut, it targets one of the most common and disruptive everyday digestive complaints.
Its long history of safe, constant use in food makes it an easy herb to lean on without much risk.
Persian Perspective›
Persian kitchens and medicine reach for mint constantly — stirred into doogh, paired with yogurt, folded into soups, and brewed as a cooling summer tea.
Ancient Egyptian medical texts, including the Ebers Papyrus, mention mint for digestive complaints, and Greek mythology ties the plant to the nymph Minthe.
Classical Persian medicine considered mint 'cooling' in its energetic character, useful for calming excess heat in the stomach and the mind alike.
Where tradition and science agree
- Both tradition and modern trials point to the gut as mint's strongest, most reliable domain — a food and remedy for easing an unsettled stomach.
- Both treat mint as something to use often and casually — folded into daily food — rather than as an occasional, dose-measured medicine.
Where tradition and science differ›
- Persian tradition uses mint as one general cooling, digestive herb; modern research distinguishes peppermint and spearmint as having somewhat different, more specific effects — peppermint for gut symptoms, spearmint showing more interest for cognition and hormonal research.
- The clinical-grade evidence for IBS uses a specific enteric-coated capsule designed to release oil in the intestine rather than the stomach — a delivery method traditional tea or fresh leaf does not replicate.
How to use this information›
- Tuck fresh mint into salads, yogurt, or soups.
- Sip peppermint tea after meals when you feel bloated.
One small step today: Add fresh mint to today's yogurt, tea, or salad.
Mint is Persia's small daily gift — cool, calming, and always within reach.
FAQs›
Peppermint or spearmint?
Peppermint for gut, spearmint for cognition and hormones.
Why does peppermint sometimes make heartburn worse?
Peppermint relaxes the same valve at the top of the stomach that is supposed to keep acid down, so in people prone to reflux it can let more acid rise. If that's you, spearmint or another calming herb like chamomile may suit you better.
Can I just chew regular peppermint gum instead of using oil capsules?
It's a pleasant habit, but it isn't a substitute — the IBS evidence is specifically for enteric-coated capsules designed to reach the intestine intact. Gum and tea are gentler, general digestive aids rather than a tested IBS treatment.
Safety
- Enteric-coated oil should not be chewed.
If a symptom is new, severe, or persistent — or you are pregnant, on medication, or managing a chronic condition — please speak with a qualified clinician who knows you. Read Safety First.
