Arnica Effects

Healers have used arnica montana since the 1500s, according to the University of Maryland Medical Center (UMMC), and many still use it today. Topical applications such as gels, creams and ointments prepared with arnica come in herbal and homeopathic forms. Homeopathic arnica also comes as sugar-based pellets that are dissolved under the tongue. Though homeopathic arnica and topical herbal remedies are generally considered safe, it's advised to consult your health care professional before using arnica in any form.

Eases Bruising and Swelling

Practitioners often consider arnica the remedy of choice for bruising and trauma. Take homeopathic arnica as soon as possible after an injury to prevent swelling and discoloration. Apply topical arnica to affected areas to prevent or reduce edema, but do not use it if you have an open wound. Arnica also minimizes pain and swelling due to sprains or strains.

Calms Aches, Pains and Arthritis

Homeopathic arnica taken after an extensive workout may prevent the development of sore muscles. Arnica has a demonstrated anti-inflammatory effect, the Memorial Sloan-Kettering Cancer Center says. Arnica gel, cream or ointment may ease the discomfort associated with sore muscles or inflamed joints.

Aids in Post-Surgical Care

Arnica may lessen bleeding after surgery, decrease wound pain and increase healing. Sloan-Kettering says clinical trials show a beneficial effect of arnica on postoperative pain and swelling. The center also notes anti-microbial activity as shown during in vitro studies.

Side Effects

Serious side effects may occur with internal use of arnica, so only the homeopathic forms, which are highly diluted, are safe for oral use. Ingestion of the herb irritates mucous membranes and may cause dizziness, vomiting, heart irregularities and tremors, the UMMC warns. In rare instances or with prolonged use, topical applications may cause skin irritations. Sloan-Kettering advises that arnica may have a contradictory effect on the actions of antihypertensive, anticoagulant and antiplatelet drugs.
