Key Constituents
The main anti-inflammatory principles; also responsible for the plant's toxicity and contact-allergy potential.
Aromatic and supporting constituents of the flower.
Present in small amounts; relevant to the caution against internal use.
The principal astringent and anti-inflammatory constituents.
Antioxidant and anti-inflammatory constituents of the bark and leaf.
Pharmacological Actions
Topical anti-inflammatory for bruising, swelling and sprains
Helenalin, the sesquiterpene lactone of Arnica montana, shows anticancer activity against multiple tumour types in vitro and in vivo, largely by covalently inhibiting NF-kappaB p65 and inducing apoptosis (preclinical).
Anti-inflammatory and antioxidant (supports irritated/atopic skin); Relief of haemorrhoid symptoms (astringent and anti-inflammatory)
Astringent for skin irritation and minor inflammation of the skin and oral mucosa (tannins), applied topically; Relief of haemorrhoid symptoms (astringent and anti-inflammatory)
Traditional & Indicated Uses
inferred from anti-inflammatory action
Antiecchymotic / vulnerary (helps disperse bruises); Topical anti-inflammatory for bruising, swelling and sprains
Arnica montana and its constituent helenalin exert anticancer activity against several tumour types in vitro and in vivo, inhibiting NF-kappaB (p65) signalling, inducing apoptosis and synergizing with other anticancer agents (preclinical).

Safety, Cautions & Contraindications
EXTERNAL USE ONLY on unbroken skin. Arnica is toxic if swallowed and can cause stomach pain, vomiting, diarrhoea, breathing difficulty, irregular heartbeat and, in serious cases, cardiac arrest; the only safe oral form is the highly diluted homeopathic preparation.
Do not apply to broken or damaged skin, open wounds, eyes or mucous membranes.
As a member of the daisy family (Asteraceae) it can cause allergic contact dermatitis; prolonged topical use can also irritate the skin.
For topical use. Do not apply to deep wounds, serious burns or severe rectal bleeding - these need medical care.

Botanical Description
Aromatic mountain perennial herb with a basal rosette of oval, hairy leaves and one or two pairs of smaller opposite leaves on an erect, softly hairy flowering stem. Each stem bears one or a few large, bright golden-yellow, daisy-like flower heads with narrow, slightly twisted ray florets.[4]
Large, multi-stemmed deciduous shrub or small tree with broad, oval, wavy-toothed leaves, asymmetrical at the base. Unusually, it flowers in late autumn to winter after the leaves have fallen, bearing clusters of small, spidery, bright yellow flowers with narrow, crinkled, ribbon-like petals. The woody seed capsule matures the following autumn and explosively ejects its seeds ('snapping hazelnut').[14]
Habitat
Grows in acidic, nutrient-poor mountain meadows, pastures and open woodland, typically at moderate to high elevations across central and northern Europe; increasingly scarce in the wild due to habitat loss and overharvesting.[4]
Native to woodland understorey and forest margins of eastern North America; widely cultivated as an ornamental and medicinal shrub.[14]
Harvesting
The flower heads are picked by hand as they open, in mid- to late summer, and dried quickly in a warm, shaded, airy place; wild populations are protected in many regions, so cultivated or sustainably wildcrafted material is preferred.[4]
Bark is stripped from branches (not the main trunk, to avoid harming the plant) and leaves are picked in summer; both are dried for use, or steam-distilled together with twigs to produce distilled witch-hazel water, the most common commercial form.[14]
Traditional Uses
Arnica flower has a long central European folk reputation, reflected in the name 'leopard's bane' and 'mountain tobacco', as a topical remedy for bruising, sprains, muscle soreness and swelling after minor injury, applied only to unbroken skin. Internal use of the whole herb has always been considered dangerous and is confined to highly diluted homeopathic preparations.[4]
Witch hazel has a long Native American and, after adoption by European settlers, worldwide reputation as a topical astringent and anti-inflammatory remedy for skin irritation, minor wounds, bruises, insect bites and haemorrhoids, and as a soothing wash for irritated skin and mucous membranes.[14]
Preparations
Standardised flower extract formulated into a cream, gel or ointment for external application to bruises, sprains and muscle soreness on unbroken skin.
Alcoholic tincture of the dried flower heads, diluted before topical application as a compress; never taken internally in this form.
Dosage
The EU herbal monograph gives cutaneous use only, in adolescents, adults and elderly - a semi-solid preparation containing 20-25% tincture applied as a thin layer 2-3 times daily, a 50% liquid-extract preparation 2-4 times daily, or 2.5 mL of a liquid preparation as an impregnated dressing 3-4 times daily. Apply to unbroken skin only. If symptoms persist after 3 to 4 days a healthcare practitioner should be consulted. Not recommended under 12 years. Never taken by mouth except as a highly diluted homeopathic preparation. Educational reference only, not a prescription.
The EU herbal monograph on Hamamelis virginiana L., cortex gives, for cutaneous use, tincture at a strength corresponding to 5-10% in semi-solid preparations several times daily, or a dry extract (5-7.7:1, ethanol 30% m/m) at a strength corresponding to 1.3% as an ointment several times daily; for anorectal use, a decoction of 5-10 g per 250 mL up to 3 times daily as impregnated dressings. For topical use only. Educational reference only, not a prescription.
