Lesser calamint is a small minty herb from the Mediterranean. In Italy it is called nepitella or mentuccia romana. Cooks there add it to mushrooms, artichokes, beans and lamb.
The plant is a mint relative, not a true mint. Its leaves smell of mint and oregano at once. You will find it as a dried kitchen herb, a loose tea, and a strong essential oil.
Here is the honest verdict on the evidence. As a food herb, it is eaten widely and suits most people. As a remedy, there are almost no human studies, and long use in cooking does not prove it treats anything or that the concentrated oil is safe.
No one has shown how lesser calamint works in people. There are no human trials to explain.
What exists is laboratory work on the essential oil. In test tubes, the oil slows the growth of some bacteria and fungi. Whether that happens inside your body is not established.
In isolated animal gut tissue, mint-type compounds can relax muscle. That is the usual story offered for why a minty tea may ease a tight, gassy belly. It remains a lab finding, not a proven effect in you.
The warm tea itself may do some of the work. Warm fluid after a heavy meal can feel settling on its own.
Lesser calamint is sold in a few plain forms. The kitchen forms are the mild ones.
- Fresh sprigs, mostly at Italian markets and in gardens. - Dried leaf, sold as a cooking herb. - Loose dried herb for tea, sometimes blended with other mints.
The distilled forms are much stronger.
- Essential oil, sold for scent and for cleaning products. - Hydrosol (the scented water left after distilling), used on skin and linen.
The essential oil is the form behind the safety warnings on this page.
Capsules and standard extracts are rare. Where they exist, the label often does not state the pulegone content.
Lesser calamint has a long record in Italian and wider Mediterranean cooking. Roman and later Italian writers mention a mint-like herb of this kind. Nepitella stayed a standard partner for wild mushrooms and artichokes.
European folk use ran alongside the cooking use. People drank the leaf as a warm tea after heavy food. It was also taken for wind, mild stomach cramps and chesty colds.
Dried bunches were hung in cupboards to keep insects off stored cloth and grain. Country healers sometimes used a wash of the herb on sore skin. These accounts describe what people did in the past, not what you should do now.
Stop and see a doctor if a stomach problem lasts more than two weeks, or if it comes with weight loss, vomiting or blood.
Get urgent medical help if you notice any of these after taking the herb or oil:
- Yellow skin or yellow eyes - Dark urine or pale stools - Pain in the upper right side of your belly - Repeated vomiting or deep tiredness - A seizure, confusion or fainting - Swelling of the lips or tongue, a rash, or trouble breathing
If anyone swallows the essential oil, call your poison centre or emergency number straight away.
In the EU, including Italy, lesser calamint is an ordinary food herb and may be sold as a tea. It is not approved as a medicine, so sellers cannot claim it treats disease.
Pulegone is capped in food and drink flavourings under EU rules. In the United States, the FDA withdrew approval for pulegone as a synthetic flavouring in 2018.
