💊 Medicinal Uses

Renowned sedative and nervine; valerenic acid in root binds GABA receptors to promote relaxation and sleep. Used for insomnia, anxiety, nervous tension, and mild muscle spasms. Avoid prolonged use; may cause vivid dreams or morning drowsiness in some individuals.

📜 History & Traditional Uses

Used since ancient Greece and Rome as a sleep aid. Known as 'all-heal' in medieval Europe. WWI soldiers used it for shell shock. Galen prescribed it for insomnia. Native to Europe and parts of Asia, naturalized in North America.

📝 Notes

Harvest roots in fall of second year for highest potency. Flowers attract beneficial insects and pollinators. Cats are strongly attracted to valerian, similar to catnip. Divide every 3–4 years. Roots have a distinct earthy, musky odor when dried.
