Key Constituents
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.
Pharmacological Actions
Appetite stimulant for loss of appetite (approved use under German Commission E)
Bitter digestive / stomachic for indigestion and dyspepsia (stimulates saliva and gastric secretion)

Safety, Cautions & Contraindications
As a member of the daisy family (Asteraceae/ragweed), it can cause allergic reactions in sensitive people; high doses reportedly cause stomach cramps, nausea and vomiting.
Avoid during pregnancy because of a traditional uterine-stimulating reputation.
Although traditionally used to support milk supply, there is no scientifically valid clinical evidence for the galactagogue use.
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
Branching annual herb with a hairy, reddish, ridged stem and spiny, deeply lobed leaves with prominent pale veins. The flower heads are pale yellow, thistle-like, surrounded by a whorl of spiny, leaf-like bracts, giving the plant its 'spotted thistle' appearance.[4]
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
Grows on dry, sunny waste ground, roadsides and rocky slopes; native to the Mediterranean region and Western Asia and naturalised elsewhere as a garden escape.[4]
Harvesting
The flowering aerial parts are cut as the plant comes into flower, in summer, and dried in a warm, shaded, airy place to preserve the bitter principle cnicin.[4]
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
Blessed thistle has a long European folk reputation as a bitter digestive tonic for loss of appetite and dyspepsia (an approved use under German Commission E) and, more anecdotally, as a traditional galactagogue to support breast-milk supply, though robust clinical evidence for the latter is lacking.[4, 11]
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 flowering herb infused briefly in hot water as a bitter digestive tea, taken before meals.
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
Traditional herbal references suggest around 1-2 g of dried herb per cup, taken before meals, up to three times daily. Educational reference only, not a prescription.

Pairings
Not documented
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]
