A tall perennial 1–1.5 m with pinnate leaves, clusters of small fragrant pale pink-white flowers, and a strong-smelling fibrous root that cats famously love. The root is the medicinal part.

Historical Background

Valerian has been Europe's principal sleep and nervine herb since antiquity — used by Greeks and Romans and prescribed for centuries for anxiety, restlessness, and insomnia. In the 20th century it became one of the most-studied herbal sedatives and remains a pharmacy staple in Europe.

Earliest recorded uses: Dioscorides and Galen; widely used in European monastic and folk medicine for nervous unrest.

Cultural significance: Valerian's pungent root — which attracts cats — was an 'all-heal' of European gardens, and its modern reputation as 'nature's valium' reflects centuries of use for sleep, though it is not a benzodiazepine and works differently.

Traditional Uses

These uses document historical traditions and do not imply proven effectiveness.

Flavor & Aroma

Aroma: Strong, musky, valerian-like (some find unpleasant)

Tea Information

Research Summary

Valerian is among the better-studied sleep herbs; several trials suggest modest improvement in sleep quality and reduced time to fall asleep, though results vary and effects are small. It is not a treatment for chronic insomnia or anxiety disorders, and should not replace prescribed therapy.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
