Medicinal Herb: Arnica montana
(Arnica montana L.)
Arnica, Leopard’s bane, mountain tobacco, mountain arnica, common arnica, wolfsbane.
Arnica is a perennial plant generally found in mountainous areas of Canada, the northern United States, Russia and Europe. The plant reaches a height of 30 to 60 cm (12 to 24 inches) and generally contains from one to nine large, daisy-like flower heads, which bloom during the summer months and when dried, are the primary parts used medicinally .
Arnica (Arnica montana) is very popular. Germany alone has manufactured more than 100 drug preparations containing this herb. Applied topically as a cream, ointment, liniment, salve, or tincture, arnica has been used by both Europeans and Native Americans to soothe muscle aches, reduce inflammation, and heal wounds.
While arnica has also been used internally as an herbal remedy for certain heart disorders, it should only be used in this way under the supervision of a healthcare provider. In fact, arnica in herbal form is primarily restricted to topical (external) use only, because it can cause serious side effects when it is used internally. Homeopathic arnica may be prescribed internally by a qualified homeopath or medical herbalist.
The phytochemistry of arnica is complex and wide ranging and includes flavonoid glycosides, terpenoids, amines and fatty acid components. Other components found in arnica include the bitter compound arnicin, caffeic acid, carotenoids (alpha- and beta-carotene, cryptoxanthin, lutein), phytosterols, resin, tannins, lignans, and anthoxanthine .
The plant extracts have been reported to possess antibacterial, antitumor, antioxidant, anti-inflammatory, antifungal and immunomodulatory activity [2,3].
Medicinal Uses and Indications
Arnica has been used for centuries in traditional herbalism as a remedy for trauma-, strain- and/or inflammation-related conditions of the locomotor system and is one of the natural remedies most often used for rheumatologic conditions as well as a treatment for acne, boils, bruises, rashes, and wounds. 
Arnica is used topically for a wide range of conditions including bruises, sprains, muscle aches, wound healing, acne, superficial phlebitis, rheumatic pain, inflammation from insect bites, and swelling due to fractures.
An experienced clinician may recommend arnica as an herbal remedy for senile heart, angina, or coronary artery disease.
Homeopathic preparations are also used to treat sore muscles, bruises, and other conditions associated with overexertion or trauma. Homeopathic doses are very diluted and generally considered safe for internal use when taken in accordance with the directions on the product labelling.
Application in Herbal Medicine:
Reduce pain and swelling.
Promotes the healing of wounds, bruises, and irritation. Caution: Use only very diluted tincture externally as it can cause inflammation and blistering when applied.
In countries where Arnica is indigenous, it has long been a popular remedy. In the North American colonies the flowers are used in preference to the rhizome. They have a discutient property (capable of dissipating diseased matter). The tincture is used for external application to sprains, bruises, and wounds, and as a paint for chilblains when the skin is unbroken. Repeated applications may produce severe inflammation. It is seldom used internally, because of its irritant effect on the stomach. Its action is stimulant and diuretic, and it is chiefly used in low fevers and paralytic affections.
Arnica is also used sometimes to relieve abdominal pains, when used as a poultice.
