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.
Pharmacological Actions
Andrographolide, the principal diterpene lactone of Andrographis paniculata, suppresses proliferation and induces apoptosis across breast, lung, colon, cervical, hepatic and haematological cancers via NF-kappaB and PI3K/Akt inhibition (preclinical).
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
Andrographolide (from Andrographis paniculata) acts as a chemopreventive and antitumour agent against breast, lung, colorectal, cervical, prostate and hepatocellular cancers and leukaemia, inducing apoptosis and inhibiting NF-kappaB and PI3K/AKT signalling (preclinical).
Symptomatic relief of the common cold and acute upper respiratory tract infection (reduces symptom severity and duration)
Immunostimulant / immune support

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
Avoid in pregnancy and when trying to conceive: high doses have shown reproductive toxicity in animals and the herb has a traditional reputation as an abortifacient.
High doses have caused nephrotoxicity and reproductive toxicity in studies; use standardized products at recommended doses and avoid prolonged high-dose use.
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.
External Ids
Botanical Description
Erect, branching annual herb with a slender, quadrangular (square-sectioned), dark green stem. The leaves are opposite, lance-shaped and glabrous, with a short stalk. Small, two-lipped, white flowers with purple-pink markings are borne in loose, spreading axillary and terminal racemes. The whole plant, and especially the leaves, is intensely and characteristically bitter.[11]
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]
Habitat
Native to India and Sri Lanka and widely distributed through South and Southeast Asia, growing wild in plains, hillsides, roadsides and cultivated fields; also grown commercially as a medicinal crop.[11]
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]
Harvesting
The aerial parts (leaves and tender stems) are cut just before or at the onset of flowering, when andrographolide content is typically highest, and dried in shade to preserve the bitter diterpenoid lactones.[11]
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]
Traditional Uses
Andrographis, the 'king of bitters', is a cornerstone bitter tonic of Ayurvedic and traditional Chinese medicine (Chuan xin lian), used for fevers, colds, sore throat, infections and liver complaints. This traditional reputation for treating the common cold and upper respiratory infections is now supported by clinical trials of standardised extracts.[10, 12]
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]
Preparations
Dried aerial parts infused or lightly decocted in hot water as a very bitter traditional fever and cold remedy.
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
Clinical trials for upper respiratory infection commonly use extracts standardised to around 60-120 mg andrographolide daily, in divided doses, for up to 5-7 days. Educational reference only, not a prescription.
The WHO monograph on Herba Andrographidis gives, by indication - for the common cold, 1.5-3.0 g of the powdered crude drug three times daily, after meals and at bedtime; for pyrexia, a decoction from 3 g of the crude drug twice daily; for diarrhoea, a decoction from 3-9 g as a single dose as needed, or two 500 mg tablets four times daily. Note that the EMA HMPC assessed this herb and issued a public statement rather than a monograph, so there is no EU posology. Educational reference only, not a prescription.
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.
