Arnica refers to a family of perennials that grow in the Northern Hemisphere. It has a long history as a medicinal herb. However, its safety for some applications has been questioned.
Accepted Uses for Arnica
The most accepted approach to Arnica is to use it as the active natural ingredient in a cream, gel, oil, ointment or tincture. "Arnica bruise cream" is then rubbed on painful areas such as bruises or sprains, sore muscles or rheumatic joints. A tincture or oil could be applied with a bandage or rubbed on.
For example, the Web MD site mentions both Arnica and witch hazel as external treatments for bruises.
The important feature is that the Arnica ointment should only be applied to undamaged skin; it should not be allowed contact with a cut, scrape or rash.
Even those not allergic to Arnica might develop a rash after prolonged use. This would indicate that treatment should stop, at least until the rash clears up.
As noted, some people are allergic to Arnica. Obviously they should avoid using it in any form.
Controversial Uses for Arnica
Arnica is used in some homeopathic remedies. While homeopathy has achieved some level of acceptance, some medical practitioners would doubt whether any homeopathic remedy is effective.
However, some people would use Arnica in higher concentrations than found in homeopathic preparations. The major controversy is that it is not considered safe for human consumption. Symptoms of Arnica overdose include dizziness, high blood pressure, irregular heart rate, tremors and vomiting. It can be fatal.
As is common for controversial treatments, whether in regular or natural medicine, the key advice is "seek and follow the advice of a licensed health care practitioner". An oral form of Arnica might not be available by prescription, depending on the jurisdiction.
Arnica in the Wild
The most common member of this family is Arnica montana. It is native to Eurasia and is found in temperate Northern regions in North America also. At least eight varieties of Arnica alpina, as well as other relatives, are found in sub-Artic regions. They grow in a variety of conditions, with a non-exclusive preference for slopes and hillsides, sandy or gravel soil and good drainage.
The yellow-and-orange flower rises about 25 to 50 cm above the ground on a circular stem that has "sparse" hairs. The leaves only grow near the ground.
