Key Constituents
Red pigments historically used to standardise extracts; contribute to antiviral activity and are the compounds responsible for photosensitivity risk.
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.
Antioxidant flavonoids contributing to overall activity.
The high mucilage content gives the demulcent, soothing action.
The blue-purple pigments and antioxidant constituents.
Phenolic constituents associated with antioxidant and reported antiproliferative (anticancer) activity in cell studies.
Pharmacological Actions
Anti-inflammatory, analgesic and wound-healing (preclinical)
Antibacterial / antimicrobial (methanolic leaf extracts; the naphthoquinone Malvone A)
Demulcent for irritation of the mouth or throat and associated dry cough (soothing mucilage); Mild laxative for occasional constipation (mucilage; traditional)
Mild laxative for occasional constipation (mucilage; traditional)

Safety, Cautions & Contraindications
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.
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).
Generally very well tolerated. Irritation of the mouth/throat or a cough that persists beyond about a week, or is accompanied by fever or breathlessness, needs medical assessment.
Use in pregnancy and breastfeeding is not recommended in the absence of adequate data.

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]
Biennial or short-lived perennial herb, 30-120 cm tall, with erect or sprawling, branched, often reddish stems. Leaves are alternate, long-stalked and palmately lobed with 5-7 shallow rounded lobes and toothed margins. Flowers are pink-purple with darker veining, with five notch-tipped petals borne in small axillary clusters. The fruit is a flattened, disc-shaped schizocarp ('cheese') that splits into a ring of small single-seeded nutlets.[2]
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]
Common on roadsides, waste ground, hedgebanks and field margins across Europe, North Africa and temperate Asia, and widely naturalised elsewhere; tolerates a wide range of soils, favouring sunny, disturbed, nitrogen-rich sites.[2]
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]
Leaves and flowers are gathered during the flowering period (summer) and dried quickly out of direct sun to preserve their mucilage content; fresh material can also be used directly for infusions or poultices.[11]
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]
Mallow leaf and flower have a long ethnobotanical history across Europe as a demulcent for irritated mucous membranes - soothing coughs, sore throat and mouth irritation - and for occasional constipation and skin irritation, reflecting the mucilage-rich leaf and flower. Modern phytochemical and pharmacological work confirms antioxidant, anti-inflammatory, antimicrobial and wound-healing activity of its extracts.[2, 11]
Preparations
Flowering-top extract standardised to hypericin and/or hyperforin content, taken as tablets or capsules; the best-studied clinical form for mood support.
Dosage
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.
EMA herbal-monograph guidance suggests roughly 1.5-2 g of dried leaf or flower per cup, taken as an infusion up to 3 times daily. Educational reference only, not a prescription.

Pairings
St John's wort raises serotonin activity and can cause serotonin syndrome when combined with other serotonin-boosting agents; pairing it with another mood-active, serotonergic herb such as saffron may add to this risk.[30]
St John's wort is a strong enzyme inducer and increases serotonin activity; combining it with another antidepressant-type herb such as rhodiola may add to serotonergic effects and unpredictably change how each is handled by the body.[30]
St John's wort speeds up the breakdown of many substances and also raises serotonin activity; pairing it with a sedative herb such as valerian may add to drowsiness and can unpredictably change how each is handled by the body.[30, 31]
St John's wort is a strong enzyme inducer and kava is a liver-metabolised sedative; combining them may add to central-nervous-system effects and alter how kava is processed, so combined use warrants caution.[30, 31]
