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.
The volatile oil, dominated by 1,8-cineole and camphor, gives the characteristic aroma and much of the antimicrobial activity.
Potent antioxidant diterpenes considered largely responsible for rosemary's strong preservative and antioxidant activity.

Safety, Cautions & Contraindications
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).
Culinary use is entirely safe. Essential oil should not be ingested in large amounts; avoid during pregnancy in medicinal doses. May trigger epileptic seizures in predisposed individuals at high doses. May interact with anticoagulants and antiplatelet drugs.
Duke (2002) does not appear to include a dedicated entry for rosemary (Salvia rosmarinus / Rosmarinus officinalis) as a primary herb entry in the section searched; however, rosemary is referenced throughout the text in relation to antioxidant and antimicrobial properties of its key compounds (carnosol, rosmarinic acid). Commission E (KOM) approves rosemary for dyspeptic complaints and externally for rheumatic conditions and circulatory problems.

Botanical Description
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]
Evergreen, woody shrub (Lamiaceae), 1-2 m tall, with dense, needle-like, dark green, aromatic leaves, white-felted beneath. Small, pale blue to violet, two-lipped flowers are borne in the leaf axils.[1]
Habitat
Native to the Mediterranean coast, growing on dry, rocky, sunny slopes and coastal scrub; widely cultivated as a culinary and medicinal herb worldwide, tolerating poor, well-drained soils and drought.[1]
Harvesting
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]
Leafy sprigs are cut throughout the year (the plant is evergreen), though essential-oil content is often considered highest just before or during flowering; leaves are stripped from the stem and dried, or used fresh.[1]
Traditional Uses
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]
Rosemary has an ancient Mediterranean reputation as a memory and circulation tonic ('rosemary for remembrance'), a digestive carminative, and an antiseptic for minor wounds. Commission E approves it for dyspeptic complaints internally and for rheumatic conditions and circulatory problems externally; modern research on rosmarinic acid and carnosic acid supports antioxidant, anti-inflammatory, antimicrobial and cognitive-supportive activity.[1]
Preparations
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
Commission E approves rosemary for dyspeptic complaints (internal use) and, externally, for rheumatic conditions and circulatory problems; typical internal use is roughly 2-4 g dried leaf as tea, up to three times daily. Educational reference only, not a prescription; avoid concentrated essential oil internally and in pregnancy/epilepsy.

Pairings
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]
