Key Constituents
Principal diuretic and antioxidant constituents of the leaf.
Characteristic bark triterpenes, betulin giving birch bark its white colour; studied for anticancer and anti-inflammatory activity.
Contribute to the astringent and antioxidant properties of the bark and leaf.
Trans-anethole typically makes up the great majority of the volatile oil and gives anise its characteristic liquorice aroma and much of its digestive and antimicrobial activity.
The fruit's lipid fraction.

Safety, Cautions & Contraindications
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.
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).
Generally safe when consumed in food amounts. Doses up to 20g daily considered safe for adults. May cause allergic reactions in some people. Caution advised during pregnancy and breastfeeding - stick to food amounts. Anethole can be toxic at high concentrations, particularly to the nervous system. Not enough safety data for medicinal use in children.
Duke (2002) provides clinical evidence (score 2) for anise as an antibacterial, antiseptic, antispasmodic, and expectorant. It has demonstrated estrogenic activity and is used as a clinically supported lactagogue to promote milk production. Commission E and WHO have both approved its use for catarrh and gastrointestinal spasms. Typical dosages are 0.5–1 g crushed seed three times per day in tea, or 0.05–0.2 ml of the fruit essential oil (Duke, 2002).
External Ids
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]
Annual herb (Apiaceae), 30-60 cm tall, with an erect, downy stem. Lower leaves are rounded and toothed or shallowly lobed, while upper leaves are finely feathery and pinnately divided. Small white flowers are borne in compound umbels, followed by small, ridged, downy fruit ('aniseed') with a strong, sweet, liquorice scent.
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]
Native to the eastern Mediterranean and south-west Asia, widely cultivated as a spice and medicinal crop in warm-temperate regions worldwide, needing a long, warm growing season and well-drained soil.
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]
Fruit ('seed') is harvested in late summer once the umbels have dried and turned brown, then threshed and dried further.
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]
Anise has a long Mediterranean and Middle Eastern tradition as a carminative digestive remedy for bloating and indigestion, an expectorant for coughs and catarrh, and a traditional galactagogue (milk-promoting) herb for nursing mothers. Commission E and WHO both approve its traditional use for catarrh of the upper respiratory tract and gastrointestinal spasms.[11, 12, 13, 14, 15]
Preparations
Dosage
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.
Duke (2002): about 0.5-1 g crushed seed three times daily in tea, or 0.05-0.2 mL of the fruit essential oil. Food amounts up to about 20 g/day are generally considered safe for adults. Avoid medicinal doses in pregnancy and in children given limited safety data. Educational reference only, not a prescription.
