Although the herb itself is poisonous, when used in commercially prepared diluted doses, arnica can be used to help treat a whole host of ailments for your pet. Arnica gets its healing properties from the substances found within the herb itself: helenalin, flavonoids, and phenolic acids. It is said to reduce swelling and inflammation by increasing blood flow to the affected tissue and draining fluid away from it. It does this by encouraging capillaries (tiny blood vessels) to open up, and by increasing lymphatic drainage.
Although scientific studies proving the effectiveness of arnica as a treatment for any medical condition are few and far between, it has been used in homeopathy and western herbal practices for many years to treat both humans and animals. It is best used in conjunction with conventional medical treatments, such as antibiotics and anti-inflammatories, and you should always seek advice from your veterinarian before using it to treat your pet.
What Is Arnica Used For?
Arnica is thought to be useful in treating a myriad of conditions that cause swelling, bruising, pain, and inflammation in your pet.
- Closed-tissue injuries
- Muscle aches
- Emotional trauma
- Post-surgical pain and swelling
- Hair loss
- Heart conditions
As arnica has anti-inflammatory properties, it is most commonly used to treat pain, as well as bruising (bruising is caused when trauma causes tiny blood vessels in the skin to burst). The effects of arnica on improving blood circulation to the affected area and increasing lymphatic drainage mean that it can speed up the healing process, as well as help manage chronic pain.
Some evidence exists to suggest that when used post-surgery, arnica may enhance the effects of veterinary-prescribed anti-inflammatory medications, or provide suitable alternative post-operative pain relief. So, if your dog is due to have surgery, it may be worth considering using arnica to help aid the healing process.
It’s important to remember that arnica is best used as a supplement to conventional veterinary-prescribed medications. If you do want to use arnica to treat your pet, then make sure you seek advice from your veterinarian first.
