Arnica is well known for its external uses under various pharmaceutical preparations against bruises, blows, bruises but do not be fooled if you discover the fallow grass, the plantain of the Alps, the tobacco of the Vosges or the mountain arnique, its other names, in nature, it is very toxic.

Arnica, against bruises and bumps

Arnica montana is a perennial plant of the family Asteraceae, measuring 40 to 60 cm high which grows mainly in mountain meadows (up to 2400 m altitude) to the acid soils of the Vosges, the Alps, and the Jura. These conditions are difficult to apply to the cultivation of Arnica montana for production, which makes the pharmaceutical industry overexploit its wild development.

Arnica montana against bruises, bumps, blows

It is characterized by a single upright stem, hairy, emerging from a rosette of leaves at the base, carrying one or two pairs of opposite lanceolate leaves, with very pronounced veins. At its end is developed in June and July, one or more golden yellow heads of 7-8 cm in diameter, giving off an aromatic and pungent odor rich in thymol.

The flowers of Arnica montana contain, in addition to this aromatic essence, carotenoid pigments, sesquiterpenic lactones (helenaline), flavonoids (spinacetin, hispidulin), coumarins (umbelliferone, scopoletin).

In internal use, arnica is dangerous because ingestion of all parts of the plant can cause an alteration of the nervous system, resulting in headaches, cold sweats, heart palpitations, breathing difficulties and abdominal pain.

The medicinal properties of arnica

Although the properties of arnica were discovered in the Middle Ages, the preparation of the Arnica tincture as it is still used today dates back to the 18th century.

Used only externally, Arnica montana stimulates the circulatory and nervous system, giving it anti-ecchymotic (anti-bruising) and antiphlogistic (anti-inflammatory) properties, but is only used on lesions without open wound.

Against bruises, sprains, muscular and articular pains, the external application of arnica is very effective and can quickly resorb hematomas.

Against gum inflammation and mouth ulcers, arnica-based mouthwashes provide relief.
