arnica

Arnica is a plant with yellow flowers. These flowers can be dried and used medicinally, especially as a lotion or ointment that's also known as arnica.

Using arnica on sore muscles or injuries — or taking arnica tablets for muscle pain — is considered an herbal or homeopathic remedy. The usefulness of arnica isn't proven by conventional medicine, but many people use it for bruising or soreness. The plant itself is native to cool areas of the Northern Hemisphere, and arnica includes dozens of different species. While arnica is a Latin word, its origin isn't known.
