QUICK ANSWER

Valerian Root: Sleep onset · mild anxiety. Traditional sedative herb that promotes faster sleep onset. Effects build over 2-4 weeks of consistent use. Standard dose 500 mg standardised, taken in the evening, about $11/month. Evidence rating: moderate evidence.

What is Valerian Root?

Valerian root has been used as a sleep and calming herb since at least ancient Greece. Its active compounds, valerenic acid and valepotriates, appear to modulate GABA receptors in a manner similar to mild sedatives, though without the dependence risk. Unlike fast-acting sleep aids, valerian's benefits typically emerge gradually over 2-4 weeks of consistent nightly use. Clinical reviews suggest improvements in sleep onset latency and subjective sleep quality, particularly in adults with mild insomnia. Standard doses range from 300-600 mg of standardized extract taken 30-60 minutes before bed. The earthy smell is famously strong, capsules are the preferred format.
