Valeriana officinalis 6X
Also known as: Valerian, Valerian root, Valeriana officinalis
Overview
Valeriana officinalis, commonly known as valerian, is a perennial plant native to Europe and Asia, with its root being utilized for medicinal purposes. It is primarily used as a sleep aid and for anxiety relief. Valerian is known for its sedative properties and is available in various forms, including teas, capsules, and extracts. While generally considered safe, the evidence supporting valerian's efficacy is mixed and inconclusive, necessitating more rigorous clinical trials. Some studies suggest potential benefits in improving sleep quality and reducing sleep latency. However, the overall quality of evidence remains a concern, with systematic reviews indicating inconsistent support for its effectiveness in treating insomnia. Further research is needed to fully elucidate its benefits and optimal usage.
Benefits
Valerian is primarily used to improve sleep quality and reduce sleep latency, although the evidence is inconsistent. Some studies suggest that it may help elderly individuals experience improved sleep quality. Potential benefits for anxiety and stress relief have also been noted, but the evidence is limited. The clinical significance of valerian's effects is uncertain due to variability in study findings. Benefits, if present, may be observed within a few days to weeks of consistent use. A study by Taavoni et al. (2011) found some benefits in sleep quality among women taking valerian capsules, though results were mixed.
How it works
Valerian's mechanism of action is thought to involve interactions with GABA receptors in the central nervous system, which can influence sleep and relaxation. It primarily affects the central nervous system, potentially impacting sleep-wake cycles. GABA receptors are a proposed molecular target, although this has not been fully elucidated. The bioavailability of valerian compounds is not well-studied, but its sedative effects are believed to be mediated through GABAergic pathways.
Side effects
Valerian is generally considered safe, but long-term effects are not well-documented. Common side effects include diarrhea, which has been reported in some studies. Uncommon side effects may include headaches and dizziness, although these are not frequently reported. Rare side effects are not well-documented. Valerian may interact with sedatives or antidepressants, although evidence is limited. It is contraindicated during pregnancy or breastfeeding due to a lack of safety data. Elderly individuals may be more sensitive to its sedative effects. It's important to consult with a healthcare provider before use, especially if taking other medications.
Dosage
The typical dosage of valerian ranges from 500 mg to 1,500 mg per day, although optimal dosing is not well-established. A common minimum effective dose is around 500 mg to 1,000 mg. Doses above 1,500 mg are not commonly studied, and the maximum safe dose is not clearly defined. It is best taken before bedtime, typically 30 minutes to 1 hour prior. Valerian is commonly available in capsule or extract form. Bioavailability may vary depending on the preparation. No specific cofactors are required for its effectiveness.
FAQs

- https://pubmed.ncbi.nlm.nih.gov/10767649/ – A systematic review by Bent et al. (2006) assessed valerian as a treatment for insomnia. The review concluded that the evidence supporting valerian's effectiveness for insomnia is inconclusive, emphasizing the need for more rigorous and well-designed clinical trials to determine its true efficacy.
- https://faculty.washington.edu/vitiello/Recent%20Publications/Taibi%20Valerian%20Review.pdf – A double-blind crossover trial by Leathwood and Chauffard investigated the effects of valerian on sleep. The study found that valerian significantly reduced actigraphic sleep latency compared to a placebo, suggesting a potential benefit for initiating sleep, although subjective sleep quality did not show significant differences.
