Arnica

Arnica is used for bruises, sprains, and dislocations, rheumatism, as well as skin inflammation.

Arnica has also been proven effective for the common cold, cough, bronchitis, fever, sore throat, and a tendency to infection. However, it is no longer recommended for these conditions due to its dangerous side effects. Modern use is limited to external applications. Unproven uses in folk medicine include heart problems, chest pain, hardening of the arteries, severe uterine bleeding, fatigue, boils, insect bites, and inflamed veins. Do not take Arnica internally; an overdose can cause serious heart problems. External use is considered safe under all medical conditions. Repeated contact with Arnica, or cosmetics containing Arnica, can cause itching, blisters, ulcers, and dead skin. However, such side effects are unlikely when the herb is applied at standard potencies for limited periods of time. No drug interactions have been reported.
