 Overview Information

Arnica is an herb that grows mainly in Siberia and central Europe, as well as temperate climates in North America. The flowers of the plant are used in medicine.

Arnica is most commonly used for pain caused by osteoarthritis, sore throat, surgery, and other conditions. Arnica is also used for bleeding, bruising, swelling after surgery, and other conditions, but there is no good scientific evidence to support these uses. Arnica can also be unsafe when taken by mouth.

In foods, Arnica is a flavor ingredient in beverages, frozen dairy desserts, candy, baked goods, gelatins, and puddings.

In manufacturing, Arnica is used in hair tonics and anti-dandruff preparations. The oil is used in perfumes and cosmetics.


 How Does It Work?

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

 : Uses & Effectiveness 

 Possibly Effective for:


© Osteoarthritis

Early research shows that using an Arnica gel product (A. Vogel Arnica Gel, Bioforce AG) twice daily for 3 weeks reduces pain and stiffness and improves function in people with osteoarthritis in the hand or knee. Other research shows that using the same gel works as well as the painkiller ibuprofen in reducing pain and improving function in the hands.


 Possibly Ineffective for:


© Reducing Pain, Swelling, and Complications of Wisdom Tooth Removal

In most research, taking Arnica by mouth does not seem to reduce pain, swelling, or complications after wisdom tooth removal. One early study suggests that taking six doses of homeopathic Arnica 30C might reduce pain, but not bleeding.


 Insufficient Evidence for:


© Bleeding

Early research suggests that placing 5 drops of a homeopathic Arnica preparation under the tongue three times per day might reduce blood loss following surgery for breast cancer. But problems with the design of this study limit the reliability of these results.


© Bruises

Most research shows that taking homeopathic Arnica by mouth or applying Arnica to the skin does not reduce bruising after surgery. But several conflicting studies shows benefit.


© Vision Problems due to Diabetes

Early research shows that taking homeopathic Arnica by mouth for 6 months reduces vision problems in people with vision loss due to diabetes.


© Muscle Soreness after Exercise

Most research shows that taking homeopathic preparations of Arnica by mouth does not prevent muscle soreness after exercise. It's unclear if applying Arnica to the skin after exercise prevents muscle soreness. Some research shows benefit. But other research shows that applying Arnica to the skin can worsen muscle pain after exercise.


© Swelling after Surgery

The effects of Arnica on swelling when applied to the skin after surgery is unclear. Some research shows a slight benefit. But other research shows that applying Arnica doesn't reduce swelling after surgery.


© Pain after Surgery

Most research shows that taking homeopathic Arnica by mouth slightly reduces pain after surgery. In some cases, homeopathic Arnica has been used together with an Arnica ointment from 72 hours after surgery for 2 weeks. But not all research has been positive.


© Stroke

Early research shows that taking one tablet of homeopathic Arnica 30C under the tongue every 2 hours for six doses does not benefit people who have had a stroke.


© Acne



© Chapped Lips



© Insect Bites



© Painful, Swollen Veins near the Surface of the Skin.



© Sore Throats



© Other Conditions


More evidence is needed to rate the effectiveness of Arnica for these uses.


 : Side Effects & Safety 

Arnica is POSSIBLY SAFE when taken by mouth in the amounts commonly found in food or when applied to unbroken skin short-term. The Canadian government, however, is concerned enough about the safety of Arnica to prohibit its use as a food ingredient.

Amounts that are larger than the amount found in food are LIKELY UNSAFE when taken by mouth. In fact, Arnica is considered poisonous and has caused death. When taken by mouth it can also 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, organ failure, increased bleeding, coma, and death.

Arnica is often listed as an ingredient in homeopathic products; however, these products are usually so dilute that they contain little or no detectable amount of Arnica.

Ø Special Precautions & Warnings:


© Pregnancy and Breast-Feeding

Don't take Arnica by mouth or apply to the skin if you are pregnant or breast-feeding. It is considered LIKELY UNSAFE.


© Allergy to Ragweed and Related Plants

Arnica may cause an allergic reaction in people who are sensitive to the Asteraceae/Compositae family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many others. If you have allergies, be sure to check with your healthcare provider before applying it to your skin. Do not take Arnica by mouth.


© Broken Skin

Don't apply Arnica to damaged or broken skin. Too much could be absorbed.


© Digestion Problems

Arnica can irritate the digestive system. Don't take it if you have irritable bowel syndrome (IBS), ulcers, Crohn's disease, or other stomach or intestinal conditions.


© Fast Heart Rate

Arnica might increase your heart rate. Don't take Arnica if you have a fast heart rate.


© High Blood Pressure

Arnica might increase blood pressure. Don't take Arnica if you have high blood pressure.


© Surgery

Arnica might cause extra bleeding during and after surgery. Stop using it at least 2 weeks before a scheduled surgery.



 Moderate Interaction

Be cautious with this combination:


©  Medications that Slow Blood Clotting (Anticoagulant/Antiplatelet Drugs) Interacts with Arnica

Arnica might slow blood clotting. Taking Arnica along with medications that also slow clotting might increase the chances of bruising and bleeding.

Some medications that slow blood clotting include:

- Aspirin;

- Clopidogrel (Plavix);

- Diclofenac (Voltaren, Cataflam, Others);

- Ibuprofen (Advil, Motrin, Others);

- Naproxen (Anaprox, Naprosyn, Others);

- Dalteparin (Fragmin);

- Enoxaparin (Lovenox);

- Heparin;

- Warfarin (Coumadin);

- and Others.



The following dose has been studied in scientific research:

Ø  Applied to the Skin:


© For Osteoarthritis

An Arnica gel product with a 50 gram/100 gram ratio (A. Vogel Arnica Gel, Bioforce AG) has been rubbed into the affected joints two to three times daily for 3 weeks
