Arnica

How does Arnica work?

The active chemicals in arnica may reduce swelling, decrease pain, and act as antibiotics.

Are there safety concerns?

Arnica products that are put on unbroken skin seem to be safe. Don't take arnica products by mouth. Don't apply it to broken or damaged skin.

Arnica is considered a poison. When taken by mouth it can cause irritation of the mouth and throat, stomach pain, vomiting, diarrhea, skin rashes, shortness of breath, a fast heartbeat, an increase in blood pressure, heart damage, coma, and death.

Do not use arnica if:

• You are pregnant or breast-feeding.
• You are allergic to ragweed, chrysanthemums, marigolds, and daisies.
• You have irritable bowel, ulcers, Chrohn's disease, or other stomach or intestinal conditions.
• You are scheduled for surgery in the next two weeks. Arnica might increase the risk of bleeding.
