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.
Historically the source of aspirin's chemical inspiration; provide the plant's analgesic and anti-inflammatory activity, buffered by co-occurring mucilage and tannins.
Antioxidant constituents contributing to the plant's anti-inflammatory and gastroprotective effects.
Contribute to astringency and the characteristic sweet almond-like fragrance.
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).
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.
Generally safe in normal culinary and medicinal doses. Avoid in salicylate sensitivity or aspirin allergy. Not recommended for children with viral illnesses (Reye's syndrome risk, as with other salicylate-containing plants). Avoid during pregnancy and breastfeeding.
Duke (2002) rates meadowsweet as ++ and notes analgesic, antiulcer, antirheumatic, astringent, and anti-aggregant activities at the experimental level (score 1). The plant is historically significant as a precursor to aspirin — salicylate compounds in meadowsweet were originally used to derive acetylsalicylic acid. Unlike aspirin, meadowsweet's salicylates are combined with protective mucilaginous compounds that may reduce gastric irritation. Duke notes that individuals with aspirin (salicylate) sensitivity should avoid meadowsweet; the plant also has anticoagulant properties that may interact with blood-thinning medications (Duke, 2002).
External Ids
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]
Tall, moisture-loving perennial herb with pinnately compound leaves, dark green above and whitish-downy beneath, the leaflets sharply toothed. Dense, fluffy, creamy-white flower clusters with a strong, sweet, almond-like fragrance are borne atop reddish, grooved stems.[1]
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]
Grows in damp meadows, marshes, riverbanks, ditches and wet woodland margins; native to Europe and temperate Asia, favouring moist, nutrient-rich ground.[1]
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]
The flowering tops, leaf and stem are cut in summer as the flowers open, when the characteristic salicylate content is highest, and dried in a warm, shaded, airy place.[1]
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]
Meadowsweet is historically significant as the plant from which salicylic acid derivatives (the chemical basis of aspirin) were first isolated, and has long been used in European folk medicine as an anti-inflammatory, analgesic and gastroprotective remedy for feverish colds, rheumatic and joint pain, and digestive complaints such as acid reflux and indigestion - notably, its natural mucilage is thought to buffer the gastric irritation associated with isolated salicylates.[1, 4]
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.
Dried flower, leaf and stem infused in hot water as a traditional anti-inflammatory and digestive tea.
Tincture (1:5) of the dried aerial parts; single dose 2-4 ml, daily dose 6-12 ml per the EU herbal monograph. Educational reference only, not a prescription.
Concentrated extract studied in vitro and in vivo for anti-inflammatory and gastroprotective activity.
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 gives a single dose of 1.5-6 g of the comminuted herb as an infusion, for a daily dose of 2-18 g, in adults and elderly; a powdered herbal substance at 250-500 mg per dose (250-1500 mg daily) and a 1:5 tincture at 2-4 mL per dose (6-12 mL daily) are also listed. Contraindicated in hypersensitivity to salicylates. For rheumatic-type complaints, not to be used for more than 4 weeks. Not recommended under 18 years. Educational reference only, not a prescription.
