Key Constituents
Principal wound-healing and anti-inflammatory constituents of the flower.
Antioxidant flavonoids and carotenoids give the flower its orange-yellow colour and contribute to its antioxidant activity.
Minor aromatic and resinous constituents of the flower head.
The antimicrobial and anti-inflammatory principles of the root; the eudesmane core and the alpha,beta-methylene-lactone ring are essential for the antimicrobial activity.
A fructan polysaccharide abundant in the root (the genus Inula gives inulin its name).
Pharmacological Actions
Calendula officinalis extracts show cytotoxic antitumor, pro-apoptotic and antimetastatic activity across many cancer cell lines and in animal models (preclinical).
Anti-inflammatory - sesquiterpene lactones (alantolactone, isoalantolactone) inhibit NF-kB and MAPK signalling and pro-inflammatory cytokines; total sesquiterpene lactones eased arthritis in animal models (potential in rheumatoid arthritis)
Antimicrobial, notably anti-staphylococcal (membrane-damaging) and anti-mycobacterial (active against Mycobacterium tuberculosis in vitro); supports respiratory and skin infection
Traditional & Indicated Uses
inferred from anti-inflammatory action
A Calendula officinalis (LACE) aqueous extract inhibits proliferation (70-100%) of leukemia, melanoma, breast, prostate, lung and colon cancer cell lines via G0/G1 arrest and caspase-3 apoptosis and inhibits melanoma growth in nude mice; a systematic review documents its cytotoxic and antimetastatic antitumour activity (preclinical).

Safety, Cautions & Contraindications
Generally very safe for topical use. May cause contact dermatitis in rare cases (Asteraceae family allergy). Internal use is safe in normal doses. Avoid during pregnancy at therapeutic doses (uterine stimulant potential). Generally safe during breastfeeding for topical use.
Duke (2002) rates calendula (Calendula officinalis) and notes anti-inflammatory, wound-healing (vulnerary), antifungal, and antispasmodic activities at experimental levels. Commission E (KOM) approves calendula flower for wound healing and anti-inflammatory uses, both topically and as a gargle. The plant contains flavonoids, triterpene saponins (oleanolic acid glycosides), and essential oils. Dose: 1–2 g dried flower as tea (for mouth rinse/gargle); or as cream/ointment containing 2–5% calendula extract for topical use. Duke notes that calendula is generally very well-tolerated, though Asteraceae sensitivity can occasionally cause allergic reactions (Duke, 2002).
The sesquiterpene lactones (especially alantolactone) are known skin sensitisers and can cause allergic contact dermatitis; people sensitive to the daisy family (Asteraceae) should be cautious.
Large doses can cause nausea, vomiting and diarrhoea; safety in pregnancy and breastfeeding is not established, so avoid medicinal doses.

Botanical Description
Aromatic annual or short-lived perennial herb with soft, hairy, oblong leaves and branching, slightly sticky stems. The flower heads are bright orange to yellow, daisy-like, with numerous narrow ray florets surrounding a darker central disc, opening in sunlight and closing at dusk.[1]
Tall, robust perennial herb with large, coarse, hairy leaves - broadly oval near the base and progressively smaller up the stem - arising from a thick, aromatic rhizome. Large, shaggy, bright yellow daisy-like flower heads with numerous narrow ray florets are borne at the top of stout, branching stems.[12]
Habitat
Widely cultivated as a garden and medicinal plant; believed native to southern Europe and the Mediterranean, now naturalised in gardens and waste ground worldwide.[1]
Grows in damp meadows, pastures, roadsides and woodland margins on moist, rich soils; native to Europe and Western Asia and naturalised in North America.[12]
Harvesting
The flower heads (or just the ray-floret petals) are picked by hand as they open, through the flowering season, and dried quickly in a warm, shaded, airy place to preserve colour and resin content.[1]
The root and rhizome are dug in autumn of the second or later year, when sesquiterpene lactone and inulin content is highest, then cleaned, sliced and dried.[12]
Traditional Uses
Calendula flower is one of the most widely used topical wound-healing and skin-soothing herbs in Western herbal medicine, applied to cuts, grazes, minor burns and skin inflammation, and used internally as a gentle anti-inflammatory and antimicrobial remedy and as a gargle for mouth and throat irritation.[1]
Elecampane root has a long European tradition, reflected in the old name 'elf dock', as a warming expectorant remedy for productive cough, bronchitis and chronic respiratory catarrh, and topically and internally as an antimicrobial for skin and wound infections.[12]
Preparations
Dried petals infused in a carrier oil, used as a soothing base for topical creams and balms for skin healing.
Standardised flower extract formulated into a cream or ointment for topical wound and skin care; the best-studied modern form.
Dried flower infused in hot water, 1-2 g in 150 ml, used still warm as a mouth rinse or gargle 2-4 times daily. The EU herbal monograph's posology for this preparation is OROMUCOSAL only - it does not support taking the infusion internally. Educational reference only, not a prescription.
Dried root simmered in water as a traditional expectorant and antimicrobial tea.
Dosage
The EU herbal monograph gives semi-solid preparations containing the equivalent of 2-10% herbal substance, applied as a thin layer to the affected area 2 to 4 times daily. Educational reference only, not a prescription.
The EU herbal monograph gives 1-2 g of the flower in 150 mL water as an infusion, used still warm for rinsing and gargling 2 to 4 times daily, or to prepare impregnated dressings for the skin. This is an oromucosal and cutaneous preparation, not an oral tea. Educational reference only, not a prescription.
