Discover how this plant, appreciated for its medicinal properties, can be an ally for your well-being

Arnica is an herbaceous plant belonging to the Arnica genus, known for its vibrant yellow flowers and its traditional use in folk medicine. Originally from the mountainous regions of Europe and North America, it is highly valued for its medicinal properties and various health applications, such as use in cases of bruises, inflammations and wounds.

This effectiveness is due to its anti-inflammatory capacity, which, according to the article Arnica montana L. – a plant of healing: review, published in the Journal of Pharmacy and Pharmacology, is derived from compounds found in the plant, called “sesquiterpene lactones”.

Arnica is widely known for its analgesic effect, making it a popular choice for relieving muscle and joint pain. When applied topically, its anti-inflammatory properties help reduce pain and stiffness, providing quick relief from bruises, strains and injuries.

In addition to relieving pain, arnica is famous for its healing properties. It stimulates blood circulation in the area to which it is applied, promoting cell regeneration and helping to accelerate the healing of cuts, scratches and bruises.

Furthermore, according to the study “Complementary Therapies in Medicine”, carried out by experts from the Department of Environmental Health Sciences at the University Hospital Freiburg, in Germany, the herb also has great potential for healing laser-induced burns. Despite this, research data highlights that more in-depth assessments are still needed.

Arnica’s anti-inflammatory properties aren’t just limited to muscle pain. It is also effective in combating inflammation in different parts of the body. Using arnica compresses can help reduce swelling and discomfort caused by joint inflammation, such as arthritis and tendonitis. To do this, you can prepare an arnica infusion, moisten a clean cloth and apply it to the affected area.

Arnica can stimulate blood circulation, which is beneficial for overall health. Good circulation is essential to ensure that nutrients and oxygen reach all cells in the body, contributing to the health of tissues and organs. By massaging your skin with an arnica oil or ointment, you not only benefit from the plant’s properties, but also improve circulation in the area.

According to data from a study by the University of São Paulo (USP), in Ribeirão Preto, published in the magazine Fapesp (Fundação de Amparo à Pesquisa do Estado de São Paulo), using arnica helps to relieve itching caused by insect bites. . The researchers decided to understand why the plant has this effect and found three substances with pharmacological activity that explain the result: two anti-inflammatories and an analgesic, proven in vitro, directly in proteins.

The research also identified what each part of the plant produces and discovered that the roots and leaves produce anti-inflammatory substances, while the analgesic is only present in the root. Despite this, the researchers do not recommend ingesting the herb under any circumstances, highlighting that, in this case, further reviews are indicated.

Arnica can be used in a variety of ways depending on the desired benefit. The most common forms include:

• Ointments and gels: to relieve pain, swelling and bruising, apply a thin layer to the affected area, massaging gently;
• Compresses: for inflammation, moistening a cloth with an arnica infusion and applying directly to the area can provide relief.

Despite its benefits, arnica has some important contraindications, especially for oral use and in specific cases of sensitivity. Some examples include:

• Oral use: it is completely contraindicated due to its toxic compounds, such as sesquiterpene lactones;
• Sensitive skin: people with sensitive skin should avoid using arnica, as it can cause allergic reactions, such as itching, redness and contact dermatitis;
• Open wounds: Arnica should not be applied to open wounds. Although it has healing properties, application to skin with deep cuts or abrasions can cause irritation and delay the healing process;
• Pregnancy and breastfeeding: The use of arnica during pregnancy and breastfeeding is not recommended. There is not enough evidence about the safety of the plant during these periods;
• Children: children are more susceptible to adverse reactions and poisoning; therefore, the use of the herb is not recommended for them;
• Prolonged use: Prolonged use of arnica in topical applications can cause skin irritation, such as peeling and inflammation. Therefore, it is recommended to use the plant in moderation and always respect the instructions for use of each product.
