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]
Habitat & Distribution
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]
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.

Traditional Use & History
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]
Preparations
Dosage
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.
