Key Constituents

Flavonoids (quercetin, myricetin, hyperoside)[1]

Principal diuretic and antioxidant constituents of the leaf.

FlavonoidsQuercetin
Triterpenes (betulin, betulinic acid)[1, 4]

Characteristic bark triterpenes, betulin giving birch bark its white colour; studied for anticancer and anti-inflammatory activity.

Terpenes / terpenoids
Tannins and phenolic acids[1]

Contribute to the astringent and antioxidant properties of the bark and leaf.

TanninsPhenolic acids
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.

Safety, Cautions & Contraindications

Safety note[13, 14, 15]Info

Generally considered safe when used appropriately. Side effects may include diarrhea, nausea, and allergic reactions (itching, rash, stuffy nose). Not recommended for individuals with edema caused by heart or kidney dysfunction. Ensure adequate fluid intake when using as a diuretic. Frequency of side effects is unknown.

Safety note[13, 14, 15, 16]Info

Duke (2002) provides clinical evidence (score 2) for birch leaf's diuretic activity, as well as for its use in urinary gravel, kidney stones, and rheumatic conditions — consistent with Commission E (KOM) and German Phytotherapy (PIP) approvals. It acts as an aquaretic, increasing urine volume without electrolyte loss. Antimelanomic activity has been demonstrated in experimental studies. The plant has a good safety profile and is classified as non-toxic at usual therapeutic doses (Duke, 2002).

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).

Botanical Description

Elegant deciduous tree with a slender trunk, distinctive smooth white bark that peels in papery horizontal strips and becomes dark and fissured near the base with age, and characteristically drooping ('pendulous') branchlets. The leaves are small, triangular to diamond-shaped, doubly toothed and long-pointed. Male and female flowers are borne in separate catkins on the same tree in spring.[1]

Height: Up to 25-30 m
Habit: Slender deciduous tree with drooping branchlets
Leaves: Small, triangular to diamond-shaped, doubly toothed, long-pointed
Flowers: Separate male and female catkins on the same tree
Stem: Slender trunk with smooth white, papery, peeling bark, dark and fissured at the base with age
Root: Shallow, wide-spreading root system
Fruit: Tiny winged seed (samara) shed from the female catkin
Flowering Period: April-May

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)

Habitat

A pioneer tree of light, well-drained, often poor or acidic soils, growing in woodland, heathland and waste ground across Europe and much of temperate Asia.[1]

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]

Harvesting

Leaves are picked in spring and early summer while young and tender; bark is collected from felled or fallen wood (living trees should not be stripped of bark, which can kill them); sap is tapped in early spring, before leaf-out, through a small hole bored in the trunk.[1]

Parts: Bark, Leaf, Sap
Season: Leaf in spring/early summer; sap in early spring before leaf-out; bark from felled wood

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

Traditional Uses

Birch leaf is a classic European 'aquaretic' diuretic used for urinary gravel, kidney stones and as a spring detoxifying tonic, and for rheumatic and joint complaints; the bark and its extracts have a long folk history for skin conditions, while the sap has been drunk fresh as a traditional spring tonic.[1]

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]

Preparations

Infusion (leaf)[1]

Dried leaf infused in hot water as a traditional diuretic and 'detox' tea, classically taken as a course in spring.

Decoction (bark)[1]

Bark simmered in water or processed into extracts for topical skin use.

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.

Dosage

Leaf infusion[12, 13]

The EU herbal monograph gives 2-3 g of the comminuted leaf in 150 mL of boiling water as an infusion, up to 4 times daily, in adolescents, adults and elderly, with adequate fluid intake; dry extract at 0.25-1 g 4 times daily and liquid extract at 15 mL 2-3 times daily are also listed. Traditionally used over a period of 2-4 weeks. Not recommended under 12 years. Educational reference only, not a prescription.

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.
