Arnica gel comes from the Arnica Montana plant, more commonly known as Wolf’s Bane or Leopard’s Bane. This topical herb is used for treatment of bruises, inflammation, joint and muscle pains, and other problems. Arnica gel has been used for hundreds of years to heal injuries and ease pain.

Arnica can be used on its own or in combination with other remedies in first aid creams and ointments. It can be taken orally, in capsules or used topically. Arnica is toxic and should not be ingested, unless it is in the highly diluted form of a homeopathic solution.

Arnica gel is mainly used as a topical anti-inflammatory treatment, a remedy for bruises and wounds, to ease joint and muscle pains, and many others. The Arnica gel is non-greasy, or oily, and can be applied easily on the skin. It does not stain clothes and can be quickly absorbed by the skin.

It is widely known that people have been using arnica homeopathic preparations for many years as a remedy for various conditions. Several studies have found that arnica gel is no better than a placebo at pain relief. However, other studies have found that it decreased pain and stiffness in people with osteoarthritis, pain after surgery for carpel tunnel syndrome and post surgery swelling after arthroscopy. Arnica Montana extract is also known to be a good homeopathic treatment for varicose veins as well as reducing the hematoma.

Active Ingredient
The active ingredient of Arnica gel is the Arnica Montana extract. According to studies, the root of the Arnica Montana plant is rich with thymol. Thymol has been clinically proven to be effective in enlarging the blood capillaries. More blood may help an injured area heal faster.

Arnica can be bought online or directly from a homeopathic doctor.


  • Osteoarthritis pain relief – Arnica gel is good for easing pain, and works similar to ibuprofen in easing away the pain caused by osteoarthritis of hands.
  • Anti-inflammatory properties – Arnica gel not only relieves muscle and joint pains, it also acts as an ant-inflammatory. Research has shown that arnica gel has the ability to decrease the swelling of the affected area by improving the blood flow in the area. In a 2008 study published in the Journal of Complementary Medicine, arnica was compared to the painkiller diclofenac, with a standard dosage taken three times per day. Diclofenac and arnica were found to perform equally well at reducing redness, swelling and heat (all signs of inflammation) in the wound.

  • Wounds –Arnica has been used to heal wounds for centuries. While there is no lack of historical and anecdotal evidence, the results of studies on arnica healing effect have been mixed.

If you have sensitive skin, apply to a small patch, and see whether there is any reaction before using regularly. If any of these symptoms occur, discontinue immediately.
