Key Constituents

Naphthodianthrones (hypericin, pseudohypericin)[4]

Red pigments historically used to standardise extracts; contribute to antiviral activity and are the compounds responsible for photosensitivity risk.

Phloroglucinols (hyperforin)[4]

Considered the principal compound behind the antidepressant activity and the main driver of the herb's potent CYP3A4/P-glycoprotein induction and drug-interaction profile.

Hyperforin
Flavonoids (hyperoside, quercetin, rutin)[4]

Antioxidant flavonoids contributing to overall activity.

FlavonoidsQuercetinRutin
Essential oil (alpha-bisabolol, chamazulene)[1, 6]

The volatile oil, concentrated in the flower head, gives chamomile its characteristic blue colour (chamazulene) and much of its anti-inflammatory activity (alpha-bisabolol).

Essential (volatile) oilAlpha-bisabololChamazulene
Flavonoids (apigenin, quercetin, luteolin, rutin)[10]

Apigenin is considered a key contributor to chamomile's sedative/anxiolytic activity via GABA-A receptor binding.

Safety, Cautions & Contraindications

Safety note[15, 16]Caution

Significant drug interactions: strongly induces CYP3A4 and P-glycoprotein, reducing plasma levels of many drugs including oral contraceptives, antiretrovirals, cyclosporine, warfarin, and digoxin. May cause photosensitivity (fair-skinned individuals). Do not combine with SSRIs, SNRIs, or MAOIs (serotonin syndrome risk). Avoid in bipolar disorder.

Safety note[15, 16, 17]Caution

Duke (2002) rates St. John's wort as ++ (raised from earlier editions) and notes antidepressant, antiviral, antibacterial, and wound-healing activities at experimental and clinical levels. Hypericin and hyperforin are identified as key active constituents. Clinical evidence (score 2) confirms antidepressant efficacy in mild-to-moderate depression, and WHO/Commission E provide approval for this indication. Dose: 300 mg standardized extract (0.3% hypericin, 3–5% hyperforin) three times daily. Duke emphasizes the critical drug interaction: St. John's wort is a potent CYP3A4 inducer and can significantly reduce blood levels of many medications including oral contraceptives, cyclosporine, antiretrovirals, and warfarin. Avoid combined use with SSRIs (serotonin syndrome risk) and pharmaceutical antidepressants (Duke, 2002).

Safety note[15, 16, 17, 18, 19]Caution

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.

Safety note[15, 16, 17, 18, 19, 20]Caution

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).

Safety note[15, 16, 17, 18, 19]Caution

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.

Safety note[15, 16, 17, 18, 19, 20]Info

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

Erect, branching perennial herb with paired, oval leaves dotted with tiny translucent oil glands that look like pinpricks when held to the light (giving the species name 'perforatum'). Bright yellow, five-petalled flowers with numerous stamens and black dots along the petal edges are borne in flat-topped clusters, and release a reddish pigment when crushed.[4]

Height: 30-90 cm
Habit: Erect, branching perennial herb
Leaves: Paired, oval, dotted with tiny translucent oil glands
Flowers: Bright yellow, five-petalled, with numerous stamens and black-dotted petal edges, in flat-topped clusters
Stem: Erect, branching, with two raised longitudinal ridges
Root: Woody rootstock with spreading rhizomes
Fruit: Small, three-valved capsule
Flowering Period: June-September (traditionally around St John's Day, 24 June)

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 in grassland, roadsides, woodland clearings and waste ground on well-drained soils; native to Europe, Western Asia and North Africa and widely naturalised elsewhere, including North America and Australia.[4]

Native to Europe and western Asia and now naturalised worldwide, growing on disturbed, sunny ground - arable field margins, waste places, roadsides and sandy or loamy soils; widely cultivated as a medicinal crop.[1, 6]

Harvesting

The flowering tops (flower and upper leaf) are cut in summer as the flowers open, around the traditional St John's Day period, and dried quickly in a warm, shaded, airy place to preserve the hypericin and hyperforin content.[4]

Parts: Flower, Leaf
Season: Summer, at flowering

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]

Parts: Flower heads
Season: Late spring to summer, at full bloom

Traditional Uses

St John's wort has a centuries-long European folk reputation as a wound-healing and nerve tonic herb, traditionally used for mild wounds, burns and nerve pain and to lift low mood; this traditional mood-supporting use is now one of the most extensively clinically studied applications of any herbal medicine, with standardised extracts shown comparable to conventional antidepressants for mild-to-moderate depression.[1, 4]

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

Standardised extract[1]

Flowering-top extract standardised to hypericin and/or hyperforin content, taken as tablets or capsules; the best-studied clinical form for mood support.

Infusion (tea)[6, 10]

Dried flower heads steeped in hot water, the classic way of taking chamomile for digestive complaints, mild anxiety and sleep support.

Essential oil[1]

Steam-distilled from the flower heads; a concentrated source of alpha-bisabolol and chamazulene, used mainly in topical and aromatherapy preparations.

Topical cream/compress[12]

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

Standardised extract[1]

Clinical trials for mild-to-moderate depression commonly use around 300 mg of standardised extract three times daily (900 mg/day total); given extensive drug interactions, use should be discussed with a healthcare provider, especially alongside other medicines. Educational reference only, not a prescription.

Infusion (tea)[15, 16, 17, 18, 19]

Traditional guidance and Duke (2002) suggest about 3 g of dried flower heads per cup of water, taken up to three times daily. Educational reference only, not a prescription.
