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[19]Info

Generally regarded as safe in culinary amounts and at normal medicinal doses; unlike the stinging nettle it has no stinging hairs.

Safety note[16, 19]Caution

Medicinal use during pregnancy or breastfeeding should be approached cautiously, as for any traditional astringent.

Safety note[17, 20]Caution

Identify correctly before foraging (resembles stinging nettle before flowering and red dead-nettle); clinical evidence is limited, so it should not replace conventional treatment.

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)

Perennial herb closely resembling stinging nettle in leaf shape but entirely without stinging hairs. Square stems bear opposite, toothed, heart-shaped leaves, and whorls of white, hooded, two-lipped flowers cluster in the upper leaf axils.[15]

Height: 20-60 cm
Habit: Erect, clump-forming perennial herb
Leaves: Opposite, toothed, heart-shaped, resembling stinging nettle but without stinging hairs
Flowers: White, hooded, two-lipped, in dense whorls in the upper leaf axils
Stem: Square (typical of the mint family), unarmed (no stinging hairs)
Root: Creeping rhizome
Fruit: Small nutlet (typical of Lamiaceae)
Flowering Period: March-November (almost year-round in mild climates)

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]

Grows in hedgerows, waste ground, gardens and roadsides on nitrogen-rich soils; native to Europe and temperate Asia, widely naturalised elsewhere.

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

The flowering tops are picked as they open, largely through spring to autumn given the long flowering season, and dried in a warm, shaded, airy place; the standardisation markers are richest in the flowering tops specifically.[15]

Parts: Flower, Leaf, Aerial parts
Season: Spring through autumn, as flowers open

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]

White dead-nettle flower has a long European folk history as an astringent remedy for catarrh and excessive menstrual or vaginal discharge, and topically as a vulnerary wash for minor wounds; the young leaves and shoots have also traditionally been eaten as a cooked spring pot-herb.

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.

Not documented

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.

Drug Class Interactions

Safety note[18, 19, 20, 21]Avoid
Drug Class: antidepressants-serotonergic
Mechanism: St John's wort raises serotonin activity; combined with SSRIs, SNRIs or MAOIs it can trigger serotonin syndrome (agitation, tremor, sweating, rapid heartbeat). Reviews of clinical reports document serotonin syndrome and lethargy when it is combined with serotonin-reuptake inhibitors.

Safety note[18, 19, 22]Avoid
Drug Class: antiretrovirals
Mechanism: Potent CYP3A4 and P-glycoprotein induction lowers antiretroviral levels (indinavir exposure fell ~57%), risking loss of viral control and drug resistance.

Safety note[18, 24, 25, 26]Avoid
Drug Class: hormonal-therapies
Mechanism: Increased metabolism of ethinylestradiol and progestins reduces contraceptive exposure, causing breakthrough bleeding, ovulation and unplanned pregnancy. Randomised and controlled trials in women confirmed more breakthrough bleeding, reduced progestin levels and evidence of ovulation when St John's wort was added to the pill.

Safety note[20, 28, 29]Avoid
Drug Class: chemotherapy-agents
Mechanism: St John's wort strongly induces CYP3A4 and P-glycoprotein, speeding the breakdown and removal of several cancer medicines. In patients it cut the active form of irinotecan (SN-38) by about 42% and reduced imatinib exposure by roughly a third - enough to weaken treatment and risk drug resistance. Do not take St John's wort during chemotherapy.
