Essential Oil – Calamintha
Botanical Information
Calamintha (Calamintha officinalis) belongs to the Lamiaceae (Labiatae) family and is an upright, bushy perennial herb that typically grows to about one metre in height. It has square stems, soft oval leaves with serrated edges that are greyish-green underneath, and small pale purple flowers. The entire plant emits a strong aromatic fragrance that is particularly attractive to cats. It is also known by several names, including Calamintha clinopodium, Melissa calamintha, calamint, common calamint, mill mountain, mountain balm, mountain mint, basil thyme, French marjoram (oil), wild basil (oil), and catnip (oil).
Distribution and Traditional Uses
Calamintha is native to Europe and parts of Asia, particularly the Himalayan region. It has become naturalised throughout North America and South Africa and is cultivated for essential oil production in Mediterranean countries, the former Yugoslavia, Poland, and the United States.
Several closely related species exist worldwide, including Lesser Calamintha (Calamintha nepeta), which has a stronger aroma and is often used interchangeably with common calamint. It is also closely related to catmint or catnip (Nepeta cataria), with which it shares many similar characteristics. It should not be confused with winter savory or summer savory, which are different plants.
Traditionally, Calamintha has been valued as a herbal remedy for nervous disorders, digestive complaints, menstrual discomfort, colds, chills, and muscle cramps. Catmint remains recognised in the British Herbal Pharmacopoeia as a traditional remedy for flatulent colic in children and for the common cold.
Essential Oil and Characteristics
Calamintha essential oil is obtained through steam distillation of the flowering tops. The oil is a pale yellow liquid with a strong herbaceous, woody aroma and a pungent scent that somewhat resembles pennyroyal.
Chemical Composition
The essential oil contains citral, nerol, citronellol, limonene, and geraniol, together with other naturally occurring aromatic compounds. The substance responsible for attracting cats is metatabilacetone, which typically represents 3–5% of the oil. The exact composition varies depending on the plant’s origin.
Therapeutic Benefits
Calamintha essential oil possesses local anaesthetic, antirheumatic, antispasmodic, astringent, carminative, diaphoretic, emmenagogue, febrifuge, nervine, sedative, and tonic properties.
In aromatherapy, it has traditionally been used to help relieve chills, cold joints, muscular aches, rheumatism, colic, flatulence, and nervous dyspepsia. It is also valued for promoting relaxation and may help reduce insomnia, nervous tension, and stress-related conditions.
Safety and Precautions
Calamintha essential oil is generally considered non-irritating and non-sensitising when properly diluted. However, it may produce toxic effects when used in high concentrations. Because of its active constituents, it should be used only in moderation and avoided during pregnancy.
Industrial Uses
Calamintha essential oil has limited commercial applications. Traditionally, it has been used in the United States as a wild cat lure because of its cat-attracting compounds. It is also occasionally incorporated into fine perfumery for its distinctive herbaceous aroma.
