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.

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.
The essential oil contains thujone, which is neurotoxic and can trigger seizures in high doses - do not exceed recommended doses and do not take the pure essential oil internally; avoid medicinal doses in epilepsy.
Avoid medicinal and essential-oil doses in pregnancy and breastfeeding (thujone; sage may also reduce milk supply). Culinary amounts are safe.

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]
Evergreen, woody-based perennial subshrub (Lamiaceae), 30-70 cm tall, with square, downy, greyish stems. Leaves are opposite, oblong, wrinkled, grey-green and softly velvety, with a strong camphoraceous aroma. Violet-blue, two-lipped flowers are borne in whorled spikes.[11]
Habitat
Native to the northern Mediterranean coast (particularly the Balkans and Italy), widely cultivated as a culinary and medicinal herb in gardens worldwide, preferring sunny, well-drained, often calcareous soils.[11]
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]
Leaves are harvested throughout the growing season, ideally just before flowering, when essential-oil content is highest, and dried quickly in a warm, shaded place.[11]
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]
Sage has an ancient reputation - its Latin name 'salvia' derives from 'salvere', to be saved or healed - as a digestive, antiseptic and cognitive tonic. It has official European herbal-monograph use for dyspeptic complaints and excessive sweating, and as a gargle for inflammation of the mouth and throat; modern clinical trials support cognitive-enhancing effects in both healthy adults and people with dementia.[11, 12]
Preparations
Dosage
EMA herbal-monograph guidance suggests about 1-3 g dried leaf per cup as an infusion, up to three times daily for digestive complaints, or a stronger preparation used as a gargle. Avoid prolonged or high-dose (essential-oil) use given the neurotoxic thujone content, especially in pregnancy and epilepsy. Educational reference only, not a prescription.
