The uses of arnica and its benefits

As we mentioned, the use of arnica, which is similar in its appearance to the daisy, dates back to ancient times. Generation after generation has used it to treat bruises and muscle aches.

Below, we’ll offer you details regarding the properties and health benefits of arnica.

Arnica is a plant from Europe that has beneficial health properties.

1. It helps to relieve pain

Arnica is popular for its anti-inflammatory properties. This is because, according to a review published in The Journal of Pharmacy and Pharmacology, it contains several chemical compounds, including flavonoids and phenolic acids. Because of this, it supposedly decreases inflammation and relieves pain.

Also, research published in The Cochrane Library on the topical use of herbs to treat osteoarthritis showed that arnica extract gel can produce effects similar to those provided by ibuprofen. Ibuprofen is a non-steroidal anti-inflammatory drug useful for the pain of people with osteoarthritis.

However, it is worth noting that studies are inconclusive regarding the effectiveness of the plant’s pain-relieving properties. Also, there is no detailed and accurate information regarding the current dose.

2. It helps to reduce bruising

Bruises appear as a result of a blow or trauma to any part of the body. They originate when blood vessels on the surface closest to the skin break as a result of the impact.

Arnica could help to reduce these marks thanks to its anti-inflammatory effects. In this regard, a review published in the American Journal of Therapeutics indicates that this plant would be more effective than a placebo for the treatment of various conditions. For example, post-traumatic and post-operative pain, edema, and bruises.

On the other hand, a study published in The British Journal of Dermatology showed that 20% arnica gel was more effective than 5% vitamin K and a placebo given to people with small hematomas created by the use of lasers.

3. It helps prevent hair loss

In addition to the benefits mentioned above, arnica may have properties to promote hair growth and prevent hair loss. It seems that the use of the oil of this plant helps reduce irritation and inflammation of the scalp.

In this case, several sources of anecdotal data validate the effectiveness of the use of arnica for this purpose and in popular in hair care routines. However, there is very little scientific documentation of it.

The main uses of arnica and how to prepare it

One of the most popular uses of arnica for its benefits is topical. However, you can also use it to prepare infusions. We’ll tell you how to prepare both of these two options.
