The root of Valeriana officinalis, a flowering plant. Contains valerenic acid and other compounds. Valerian is traditionally used for sleep and relaxation support.
Valerenic acid and other compounds bind to GABA-A receptors and enhance GABAergic inhibitory signaling in the CNS. Additional adenosine receptor activation may contribute to relaxation.
Used in traditional European herbalism for centuries for sleep and anxiety. Documented medical use since the 17th century; modern research began in 1970s-1980s.
Moderate evidence from small clinical trials suggests valerian may modestly improve sleep quality and reduce time to sleep onset in some users. Efficacy is variable and modest. Long-term effectiveness less clear. Higher-quality studies are limited.
Standard supplemental dose 300-900 mg dried root (or equivalent extract) 30-120 minutes before bedtime. Timing is critical; consult healthcare provider for individual needs.
This is general research/context information, not medical advice or a recommended protocol.
Combines with other sleep-supporting herbs like passionflower or skullcap; avoid stacking multiple CNS depressants.
If you are going to research a compound, verifying identity and purity is the single most protective step. Independent analytical testing and sterile-handling supplies reduce risk.
Compare testing optionsValerian's odor comes from volatile compounds including valerenic acid. Taste and smell are unpleasant but do not reflect efficacy.
Some users report residual drowsiness. Start with low doses to assess tolerance. If drowsy the next day, reduce dose or timing.
Long-term safety is reasonable, but tolerance (reduced efficacy) can develop. Consider cycling (off one week per month) to maintain effectiveness.
Effects often appear 30-120 minutes after intake; some users benefit after 2-4 weeks of consistent use.
Valerian is not habit-forming in the addictive sense, but tolerance can develop with chronic use; cycling helps maintain effect.
