Additional Information

Quick Facts about arnica gel (arnicare):

Arnica is a plant with yellow, daisy-like flowers and is part of the sunflower family (Asteraceae).  The plant is found mainly in North America and is known for its large yellow or orange flowers and soft, hairy leaves.  

What are the proposed benefits of Arnica?

Arnica plant extract is added to a gel or cream (Arnicare).  Most people use this medicinally to help heal bruises and burns, and to relieve the pain caused by osteoarthritis. It is also used as an herb to flavor beverages, candy, and other foods. Using arnica as a medicine or ingesting arnica in foods is generally considered safe. However, when taken in large amounts it can result in symptoms such as vomiting, diarrhea, and a fast heartbeat with possible increased risk of bleeding.  

What are the cautions with using Arnica ?

When topical products with arnica, such as Arnicare, are applied to intact, healthy skin for short periods, it has minimal toxicity. For example, using a concentrated arnica product over long periods can result in rashes, and other skin damage. Arnica is also available as homeopathic products in very small amounts, so these preparations are not likely to cause side effects when taken as directed. 

Individuals taking anticoagulants (also known as “blood thinners”), aspirin, or certain supplements, should use caution when considering arnica-containing products. Arnica can reduce the body’s ability to form blood clots which can increase the risk of bleeding. Additionally, arnica is also not recommended for use during pregnancy or while breastfeeding. As always, discuss all medications and supplements with your physician before taking them to avoid unpleasant or dangerous side effects.

Lastly, if you find someone has eaten a small amount of arnica or had a dosing mishap with an arnica supplement, do not panic. Give them some water to drink. If problems start or you have questions, call the Missouri Poison Center right away at 1-800-222-1222. Remember, the poison center is open all day, every day for poisoning emergencies and questions.
