Botanical Description

Large deciduous tree with a rounded crown and heart-shaped, finely toothed, asymmetrical leaves. Small, pale yellow, fragrant flowers hang in clusters from a distinctive pale green, leaf-like bract, developing into small, round, downy nutlets.[11]

Height: 20-30 m
Habit: Large deciduous tree with a rounded, dense crown
Leaves: Heart-shaped, finely toothed, asymmetrical at the base
Flowers: Small, pale yellow, fragrant, hanging in clusters from a pale green bract
Stem: Tall trunk with smooth grey bark, becoming furrowed with age
Root: Deep, spreading root system
Fruit: Small, round, downy nutlet, attached to the persistent bract
Flowering Period: June-July

Habitat & Distribution

Grows in deciduous woodland, hedgerows and as a widely planted street and park tree; native to Europe including Britain.[11]

Harvesting

The flowers, together with their attached bract, are picked shortly after opening in early-to-mid summer and dried quickly in a warm, shaded, airy place.[11]

Parts: Flower (lime, linden flower)
Season: Early-to-mid summer, shortly after flowers open

Key Constituents

Flavonoids (quercetin and kaempferol glycosides, tiliroside)[3, 5, 10, 11, 12, 13]

Antioxidant constituents associated with the diaphoretic and calming effects; tiliroside is highlighted as a key anxiolytic flavonoid of the genus.

Mucilage[11]

Pharmacological Actions

Anticancer (preclinical)[2, 6]
Antioxidant[2, 9, 12]

Antioxidant and acetylcholinesterase-inhibitory (linden-flower extract scavenges free radicals and inhibits AChE in vitro)

Antispasmodic[11]

Antispasmodic (traditional)

Anxiolytic / calming[9, 10, 11, 13]

Relief of mild mental stress and to aid sleep (gentle calming); flavonoid fractions of Tilia (notably tiliroside) show anxiolytic activity in animal models via the serotonergic and GABA/benzodiazepine systems (mechanistic evidence from the related species T. americana)

Demulcent (soothing mucilage)[11]

Demulcent for cough and catarrh (soothing mucilage)

Diaphoretic[11]

Diaphoretic infusion for feverish colds and flu (promotes sweating to support a fever)

Traditional Use & History

Linden flower has a long European tradition, recognised in the EU herbal monograph, as a gentle calming and sleep-supportive herb and as a diaphoretic remedy for feverish colds and flu, with modern research on its flavonoid fraction (notably tiliroside) supporting a mechanistic basis for the traditional calming action.[11]

Preparations

Infusion[11]

Dried flower (with bract) infused in hot water as the classic traditional calming and diaphoretic tea.

Dosage

Infusion[11]

The EU herbal monograph suggests around 2-4 g of dried flower per cup, up to several times daily as needed for calming or feverish colds. Educational reference only, not a prescription; well tolerated including in children per the monograph.

Safety, Cautions & Contraindications

Safety note[11]Info

Generally very well tolerated, including (per the EU herbal monograph) in children. A feverish cold that persists or worsens, or a high or prolonged fever, needs medical assessment.

Safety note[11]Caution

Use in pregnancy and breastfeeding is not recommended in the absence of adequate data.

Harvest Readiness

[14]

Part: flower
Signals: Gather the flowers only when freshly opened, in early summer - older flowers develop narcotic properties, so do not gather ageing ones.
Basis: traditional
Source Quote: Lime flowers are said to develop narcotic properties as they age and so they should only be harvested when freshly opened.
Species Confirmed: 1
Notes: PFAF (REF-3350); the flowers are gathered only when freshly opened (in flower June-July) - they develop narcotic properties as they age. Single lineage -> provisional.
