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 volatile oil, concentrated in the flower head, gives chamomile its characteristic blue colour (chamazulene) and much of its anti-inflammatory activity (alpha-bisabolol).
Apigenin is considered a key contributor to chamomile's sedative/anxiolytic activity via GABA-A receptor binding.
Minor constituents (e.g. herniarin, umbelliferone) contributing to the mild antispasmodic action.
Contribute to the soothing, demulcent effect on irritated mucous membranes.

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).
Generally considered very safe when used as tea or topical preparations.Allergy risk: People allergic to ragweed, daisies, or other Asteraceae plants may react (itching, rash).Blood thinners: Chamomile may slightly enhance effects of anticoagulants—use large amounts cautiously.Pregnancy: Normal tea amounts are usually considered safe, but concentrated extracts should be used with caution.Topical use: Rare skin irritation in sensitive individuals.
Duke (2002) rates German chamomile (Matricaria chamomilla) highly for anti-inflammatory, antispasmodic, and wound-healing activities. The essential oil contains the potent anti-inflammatory compound alpha-bisabolol. Chamomile is Commission E approved for digestive complaints and topical wound care. Dose: 3 g dried flower heads per cup of water, three times daily. Alpha-bisabolol is noted as one of the most active natural anti-inflammatory compounds known. Caution: chamomile belongs to the Asteraceae family and can cause allergic reactions in individuals sensitive to ragweed, chrysanthemums, or related plants (Duke, 2002).
Generally very safe. Rare allergic reactions in individuals sensitive to the Asteraceae family (ragweed, chrysanthemums). May cause contact dermatitis with topical essential oil use. Avoid very high doses in pregnancy. Well tolerated by children in appropriate amounts.
Scented mayweed (Matricaria chamomilla) shares the same species as German chamomile (see German Chamomile entry above). Duke (2002) provides the same clinical support: Commission E approves it for dyspeptic complaints (orally) and skin and mucous membrane inflammation (topically). Anti-inflammatory, antispasmodic, and wound-healing activities are well-established (Duke, 2002).

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]
Aromatic annual herb, 15-60 cm tall, with an erect, much-branched, hairless stem. Leaves are alternate and finely bi- to tripinnately divided into thread-like segments, giving a feathery appearance. Flower heads are small daisy-like composites, 1-2.5 cm across, with white ray florets that reflex sharply downward as the flower matures around a conical, hollow, yellow disc of tubular florets - the hollow, conical receptacle is a key feature distinguishing German chamomile from similar-looking daisies. The fruit is a tiny ribbed achene without a pappus.[1, 10]
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]
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]
Flower heads are hand- or machine-harvested at full bloom, when the ray florets are horizontal and just beginning to reflex, then dried quickly at low temperature and out of direct light to preserve the volatile oil.[6]
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]
Chamomile is one of the most widely used medicinal herbs in the world, with a long traditional history as a mild digestive, calming and anti-inflammatory remedy - taken as a tea for indigestion, cramping, and restlessness or poor sleep, and applied topically for skin and mucous-membrane inflammation and wound healing. Modern reviews confirm anti-inflammatory, antispasmodic, sedative/anxiolytic and antimicrobial pharmacological activity supporting these traditional uses.[1, 6, 10]
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 flower heads steeped in hot water, the classic way of taking chamomile for digestive complaints, mild anxiety and sleep support.
Steam-distilled from the flower heads; a concentrated source of alpha-bisabolol and chamazulene, used mainly in topical and aromatherapy preparations.
Concentrated extract or infused oil applied to skin, or as a compress - a randomised controlled trial found a topical chamomile oil preparation effective for knee osteoarthritis pain.
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.

Chamomile and valerian are both traditional mild sedatives for restlessness and poor sleep; taken together they may enhance calming and sleep effects but also add to drowsiness.[23]
Chamomile and lemon balm are both gentle calming herbs commonly combined for stress and sleep; used together their mild sedative effects may add up.[23]
