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.
Pentacyclic triterpenoids (ursolic, oleanolic and betulinic acids), the phenolic acid rosmarinic acid, coumarins (umbelliferone, scopoletin, esculetin) and the flavonoid luteolin are the main bioactives behind self-heal's antioxidant, anti-inflammatory and antimicrobial activity.
Water-extracted polysaccharides — including a partially sulphated arabinogalactomannan (PSP-2B) and polyphenolic-protein-polysaccharide conjugates (PVG/PVE30) — are the principal antiviral and immunomodulatory constituents, blocking herpes simplex virus attachment and modulating innate immune signalling.

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 very safe and well tolerated. No significant known toxicity or drug interactions. Safe for topical and internal use in normal medicinal doses. Suitable for most adults including children in appropriate doses.
Duke (2002) rates self-heal as +++ and notes antioxidant (score 2), anti-inflammatory, antiviral, and COX-2 inhibitory activities. The plant contains luteolin, rosmarinic acid, and hyperoside — all with well-documented bioactivities. Hepatoprotective activity has been experimentally demonstrated. Duke notes that self-heal has a broad antimicrobial spectrum and an impressive antioxidant profile, supporting its traditional reputation as a versatile wound-healing herb. No significant safety concerns at normal herbal doses (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]
Low, creeping to semi-erect perennial herb (Lamiaceae), 5-30 cm tall, with square, often purplish stems. Leaves are opposite, ovate with slightly toothed margins. Small, two-lipped, violet-purple flowers are densely packed into a compact, club-shaped terminal spike subtended by purplish bracts.[1]
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 throughout Europe, Asia and North America (circumboreal), extremely common in lawns, meadows, woodland clearings, roadsides and waste ground, tolerating mowing and a wide range of soils.[1]
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]
Whole flowering aerial parts (flower, leaf and stem) are cut during flowering (summer) and dried.[1]
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]
Selfheal has an extremely broad folk-medicine reputation across European, North American and Traditional Chinese Medicine traditions - as its name suggests, used as an all-purpose wound herb, gargle for sore throat, and internal remedy for fevers and inflammation. Modern research on its triterpenoid, phenolic and polysaccharide constituents supports wide-ranging antioxidant, anti-inflammatory, antimicrobial and antiviral activity.[1]
Preparations
Dried aerial parts steeped in hot water, taken internally or used as a gargle or wash.
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.
Traditional guidance suggests roughly 2-4 g dried herb per cup as an infusion, up to three times daily, or an equivalent tincture; used topically as a wash or gargle at similar strength. Educational reference only, not a prescription.
