AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Relaxation / sleep

Limited Evidence

Limited human evidence supports mild calming effects. Traditional use is long-standing across Europe.

Cold and mild fever support

Mixed Evidence

Traditional use as a 'diaphoretic' for colds; clinical evidence is sparse but the herb is well-tolerated.

How it works

Linden flowers contain flavonoids (kaempferol, quercetin glycosides), volatile oils, mucilage, and tannins. The flavonoids may have mild anxiolytic effects, possibly via GABA modulation in laboratory models, while mucilage soothes mucous membranes. Linden is traditionally used as a 'diaphoretic' to support mild fever resolution through gentle sweating. Clinical human evidence is limited; most use is traditional and based on long-standing European practice.

Dosage

Traditional tea: 1-2 g dried flowers steeped in hot water, several times daily. Tincture and extract doses vary.

When and how to take it

Tea is often taken before bed for sleep support or during mild illness. Effects are immediate but mild.
