Effects & Properties

Arnica's effects are due to its rich complex of active ingredients: sesquiterpene lactones such as Helenalin and dihydrohelenalin are the main active ingredients and have anti-inflammatory and antimicrobial effects. Flavonoids and phenolic carboxylic acids enhance the anti-inflammatory effect. The essential oil gives the plant its antiseptic properties. The antiseptic and anti-inflammatory effects of arnica flowers can even surpass those of some synthetic anti-rheumatic drugs.

Features: wound-healing, anti-inflammatory, pain-relieving, bruise-reducing, hemostatic, nourishing.

Applications

Arnica is one of naturopathy’s wound remedies—its uses are consistently based on this fundamental property.

Arnica for Bruises

With bruises, the tissue is compressed without damaging the skin—blood vessels rupture, blood leaks out, and swelling and pain result. Arnica helps stop bleeding into the tissue, relieves pain and reduces inflammation, and stimulates the tissue to heal. This significantly shortens the healing time.

Arnica montana for muscle soreness

Muscle soreness is caused by intense physical exertion, which creates tiny tears in the muscle fibers and triggers micro-inflammation. Arnica helps the tissue recover more quickly by reducing inflammation and promoting blood circulation. The muscle is then able to function optimally again.

Arnica for bruises

With bruises, blood has leaked into the surrounding tissue, causing discoloration, swelling, and tenderness. Arnica reduces inflammation, relieves pain, and accelerates the reabsorption of the leaked blood. Because it promotes reabsorption, the bruises fade much more quickly.

Arnica montana during childbirth

During childbirth, the mother’s body is subjected to extreme stress. Arnica can help reduce excessive bleeding, and its soothing, healing properties can help the mother recover more quickly from the physical strain. Swelling and exhaustion subside more quickly.

Arnica before and after surgery

After surgery, arnica helps stop bleeding from fresh wounds, accelerates tissue healing, and relieves pain—which prevents patients from adopting a protective posture and speeds up recovery overall. When taken before surgery, it helps the body prepare for tissue trauma.

Arnica montana for toothaches

After tooth extractions, the tissue is irritated, swollen, and painful. Arnica reduces swelling, slows secondary bleeding from the wound, and promotes wound healing. Discomfort following the procedure is significantly reduced, and healing proceeds with fewer complications.

Instructions for Use

In cases of injury, arnica is taken internally only in homeopathic or spagyric preparations is used. In acute cases, it may even be taken hourly; for chronic conditions, 3 times a day. For external use, arnica is usually applied as an alcoholic solution using wound dressings or bandages—these are changed 2 to 3 times a day.

Pregnancy & Breastfeeding

Always consult a doctor or naturopath before taking arnica internally during pregnancy. Arnica can be used externally without hesitation, provided you are not allergic to it.

Allergy to Asteraceae

Since arnica is a strong allergen, people with a known allergy to the Asteraceae family should avoid it. When using it topically, watch for allergic skin reactions—if any occur, wash it off immediately.

Häufige Fragen

What is Arnica montana (Arnica)?

Arnica montana—commonly known as arnica—is an alpine medicinal plant belonging to the Asteraceae family. It is a protected species and contains sesquiterpene lactones such as helenalin, as well as flavonoids and essential oils, as its main active ingredients. It is considered THE go-to plant for blunt injuries and is used internally in homeopathic or spagyric preparations, and externally as a tincture or ointment.

How does arnica help with bruises and contusions?

Arnica reduces inflammation, relieves pain, and accelerates the reabsorption of pooled blood. Bruises fade more quickly, swelling subsides, and tissue regenerates faster. Apply externally as a tincture or ointment directly to the affected area.

What other conditions does Arnica montana help with?

In addition to bruises and contusions, arnica is used to treat muscle soreness, as well as after surgeries and childbirth, and for toothaches following extractions. It is always used topically or in homeopathic/spagyric form.

Why shouldn't arnica be taken internally in high doses?

Arnica is mildly toxic when taken internally—in its undiluted form, it can cause heart arrhythmias, nausea, and irritation of the mucous membranes. In naturopathy, it is therefore used internally exclusively in homeopathic or spagyric forms, in which the toxic effects do not occur.
