Arnica montana is a flowering plant that contains a variety of compounds — some of which may be helpful, but others that can be poisonous and, for this reason, it is considered a dangerous plant.
Nevertheless, arnica has been used by some as an oral homeopathic preparation (i.e., at an extreme dilution that contains little to no arnica) to prevent bruising after surgery. It is also applied topically as a gel, ointment, cream or spray to treat bruising, swelling, and pain. However, as explained in our article, the clinical evidence is not compelling for any oral or topical use.
