Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
The characteristic bitter principle (pharmacopoeial material contains at least 0.7%); drives the expectorant and digestive actions. A phytochemical/pharmacological overview identifies marrubiin and the phenolic fraction as the basis for antioxidant, anti-inflammatory and antimicrobial activity.
Antioxidant and anti-inflammatory constituents.
Astringent and aromatic constituents of the herb.
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
As a strong bitter it may aggravate hyperacidity; theoretical caution in peptic ulcer. Large amounts have shown effects on heart rhythm and blood pressure in studies, so avoid excessive intake.
Traditional use only; a cough or digestive complaint that persists needs medical assessment. Use in pregnancy and breastfeeding is not recommended.
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
Perennial herb, 20-60 cm tall, with square, densely white-woolly (tomentose) stems characteristic of the mint family. Leaves are opposite, ovate-rounded, crinkled and coarsely toothed, grey-green and woolly beneath, with a strong bitter, slightly musky smell when crushed. Small white, two-lipped flowers are clustered in dense whorls (verticillasters) in the leaf axils up the stem. The fruit splits into four small nutlets typical of the Lamiaceae.[11]
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
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
The flowering aerial parts are cut during the flowering season (summer), when bitter marrubiin content is highest, and dried promptly out of direct sunlight; harvest site and season measurably affect the marrubiin and antioxidant content of the dried herb.[8, 11]
Whole flowering aerial parts (flower, leaf and stem) are cut during flowering (summer) and dried.[1]
Traditional Uses
White horehound has a long European and Mediterranean folk-medicine history as a bitter expectorant for coughs, bronchitis and catarrh, and as a digestive bitter for poor appetite and dyspepsia. It is one of the classic ingredients of traditional cough syrups and horehound candy. A modern critical review found reasonable, though not conclusive, scientific support for these traditional respiratory and digestive uses.[2, 11, 12]
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
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.
