Arnica Plant Healing Properties

The plant contains essential oil, phenolic substances, flavonoids, and tannin. It has remarkable stimulating properties on the heart and blood circulation. However, it is highly poisonous to the nervous system, and its internal use is no longer recommended. Arnica must be considered a toxic plant.

Externally applied, as a TINCTURE, on the skin, it has excellent vulnerary and anti-inflammatory properties, a traditional remedy for bumps, bruises, sprains, and hematomas. It is also used for furuncles and abscesses.

ARNICA TINCTURE is prepared with 20 grams of dry flowers and roots, steeping them for 15 days into 100 ml of 90% ethyl alcohol to prepare an alcoholic cold extract. The Cold extract can also be prepared with oil.


This plant can only be used in an external application since it has toxic effects on the nervous system when taken internally.

How to use Arnica

  • Tincture. Soak a compress with drops of arnica tincture dissolved in water, then apply to the affected skin area. A pure (undissolved) tincture can irritate the skin.
