Fresh, invigorating, almost magical in its simplicity—mint is undoubtedly one of the most consumed aromatic plants in the world. But behind this familiar taste lies a true natural pharmacopoeia.
A plant of a thousand faces
Mint (genus Mentha) encompasses over 25 species and hundreds of hybrids. The most common for infusions are peppermint (Mentha × piperita), known for its intense taste and rich menthol content, and spearmint (Mentha spicata), which is milder and slightly sweet. Moroccan mint, used in mint tea, is a particularly fragrant spearmint hybrid.
All varieties share common properties but with different intensities. In infusions, peppermint dominates the Western market, while spearmint reigns in the Arab and Mediterranean world.
Menthol: the molecule with superpowers
Mint's aroma and effects are primarily due to menthol, a natural cyclic alcohol that makes up 40 to 55% of peppermint essential oil. It creates that recognizable sensation of freshness—not by actually lowering temperature, but by activating the TRPM8 thermosensitive receptors in our skin and mucous membranes.
But menthol is not alone: the plant also contains menthone, menthofuran, rosmarinic acid, and numerous flavonoids like luteolin and apigenin, all endowed with anti-inflammatory and antioxidant properties.
Benefits of mint infusion
→ The great champion of digestion
This is undoubtedly where mint shines brightest. Its active compounds act as antispasmodics on the smooth muscles of the intestines, reducing cramps, bloating, and spasms. A meta-analysis published in the Journal of Clinical Gastroenterology concluded that peppermint oil was significantly more effective than a placebo in relieving the symptoms of irritable bowel syndrome (IBS).
A simple cup after a meal is enough to stimulate bile production, promote gastric emptying, and reduce mild nausea. A gentle, fast, and delicious remedy.
→ Potent anti-nausea
Mint has been used for centuries against motion sickness, pregnancy nausea (under medical supervision), and post-chemotherapy nausea. The mere inhalation of vapors from a hot cup of mint already provides relief to many patients. Aromatherapy studies have confirmed this anxiolytic and antiemetic effect.
→ Natural decongestant
Menthol has a direct action on respiratory tract receptors: it slightly dilates the bronchi, thins mucus, and facilitates breathing. During a cold, a hot peppermint infusion is more than just comfort—it's a real therapeutic gesture.
→ Cognitive stimulant
Several studies have shown that the aroma of mint improves cognitive performance: increased alertness, enhanced short-term memory, and improved concentration. A cup of mint in the morning or before an important meeting? Yes, indeed!
→ Anti-inflammatory and antioxidant action
The rosmarinic acid contained in mint is a powerful antioxidant, capable of neutralizing free radicals and inhibiting pro-inflammatory enzymes. In vitro studies also show interesting antimicrobial properties, useful for combating certain oral pathogens.
How to prepare a perfect mint infusion?
Use simmering, not boiling, water (85–90°C) to preserve delicate flavors. Steep for 5 to 10 minutes depending on your taste. For a fresh infusion from dried leaves, use 1 teaspoon per cup. For fresh leaves, gently crush them between your fingers before steeping to release essential oils.
Mint pairs divinely with lemon, honey, ginger, or even cucumber when served cold. For an oriental touch, mix it with green tea for an authentic Moroccan mint tea.
Precautions to know
Peppermint is not recommended for infants and young children (menthol can cause laryngospasm). It should also be avoided in cases of severe gastroesophageal reflux (as it relaxes the esophageal sphincter). When in doubt, the milder spearmint is always a safe alternative.
