Key Constituents

Labdane diterpene marrubiin[11, 12, 13]

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.

Terpenes / terpenoids
Flavonoids and phenylethanoid esters (e.g. verbascoside)[11, 12]

Antioxidant and anti-inflammatory constituents.

Verbascoside (acteoside)Flavonoids
Tannins and volatile oil[12]

Astringent and aromatic constituents of the herb.

Essential (volatile) oilTannins
Essential oil (thujone, 1,8-cineole, camphor, borneol)[9, 11]

Aromatic constituents; thujone is the safety-limiting compound.

Rosmarinic acid and other phenolic acids[5, 11, 12]

Safety, Cautions & Contraindications

Safety note[11]Caution

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.

Safety note[11]Caution

Traditional use only; a cough or digestive complaint that persists needs medical assessment. Use in pregnancy and breastfeeding is not recommended.

Safety note[11]Caution

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.

Safety note[11]Caution

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]

Height: 20-60 cm
Habit: Erect, bushy, white-woolly perennial herb
Leaves: Opposite, ovate-rounded, crinkled, coarsely toothed, woolly beneath
Flowers: Small, white, two-lipped, in dense axillary whorls (verticillasters)
Stem: Square, densely white-woolly (tomentose)
Root: Fibrous perennial rootstock
Fruit: Four small nutlets (typical Lamiaceae schizocarp)
Flowering Period: June-October

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]

Habit: Evergreen, woody-based perennial subshrub
Leaves: Opposite, oblong, wrinkled, grey-green, velvety, strongly aromatic
Flowers: Violet-blue, two-lipped, in whorled spikes
Stem: Square, downy, greyish, woody at the base
Root: Woody perennial rootstock
Fruit: Four small nutlets (typical Lamiaceae schizocarp)
Flowering Period: May-July

Habitat

Native to Europe, North Africa and temperate Asia and widely naturalised elsewhere, growing on dry, disturbed, sunny ground - roadsides, waste places, pastures and rocky or sandy soils.[8, 11]

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]

Parts: Aerial parts
Season: Summer, during flowering

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]

Parts: Leaf
Season: Growing season, ideally just before flowering

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

Infusion[11]

Dried aerial parts steeped in hot water as a bitter digestive and expectorant tea.

Decoction/syrup[12]

A stronger decoction, traditionally sweetened into a syrup (or made into horehound candy), for cough and sore throat.

Infusion (tea)[11]

Dried leaf steeped in hot water, for digestive complaints or excessive sweating.

Gargle/mouthwash[11]

A stronger infusion used topically for sore throat and mouth inflammation.

Standardised extract (capsule)[12, 13]

The form used in cognitive-function clinical trials.

Dosage

Infusion[11, 12]

EMA/ESCOP herbal-monograph guidance suggests about 1.5-2 g of dried aerial parts per cup, as an infusion up to 3 times daily. Educational reference only, not a prescription.

Infusion (tea)[11]

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.
