Valerian Whole Root Extract

Also known as: Valeriana officinalis, Garden valerian, Common valerian, European valerian, Valerian

Overview

Valerian (*Valeriana officinalis*) is a perennial herb found in Europe, Asia, and North America, recognized for its historical applications in traditional medicine, particularly for its sedative properties. This herb is versatile, consumed in various forms such as tea, tinctures, capsules, or tablets. Key bioactive compounds present in valerian root include valerenic acids and flavonoids, which are believed to contribute to its calming effects on the nervous system. While there is a significant body of research about valerian, the results are variable; some studies indicate clear benefits in promoting sleep, while others show little to no effect. Valerian is mainly utilized for conditions including insomnia, anxiety, and restlessness. Although its reputation as a natural remedy is well-established, more rigorous research is needed to confirm its efficacy consistently.

Benefits

Valerian is commonly recognized for its potential to enhance sleep quality by reducing sleep latency, specifically, a systematic review reported an approximate 7-minute reduction in the time it takes to fall asleep. Additionally, valerian may exert anxiolytic effects, possibly by elevating GABA levels in the brain, providing a lesser sedative impact compared to benzodiazepines. Certain populations, particularly postmenopausal women, may experience enhanced benefits when valerian is combined with other herbal treatments, such as lemon balm. However, the clinical relevance of valerian's benefits is often contested due to consistently small effect sizes observed in trials, indicating that while valerian may be helpful for some, results can vary widely among users.

How it works

Valerian primarily influences the GABAergic system, resulting in increased levels of gamma-aminobutyric acid (GABA) in the brain, which helps to calm neural activity. It also interacts with serotonin receptors, further contributing to its sedative and anxiety-reducing properties. By modulating the central nervous system's collective neurotransmitter activity, valerian induces a state of relaxation and potentially decreases anxiety, although its roles in peripheral system interactions require further investigation.

Side effects

Valerian is largely deemed safe for short-term use; however, it can lead to several side effects. Commonly reported adverse effects (over 5% incidence) include drowsiness, dizziness, and gastrointestinal upset. Less frequently, between 1% to 5% of users may report headaches, allergic reactions, or digestive issues. Rare side effects are infrequently documented. Caution is advised as valerian may enhance the sedative effects of other medications, raising the potential for compounded sedation. Contraindications are noted for pregnant or nursing women and children under 3 years. Individuals on sedative medications should exercise particular caution due to potential additive effects.

Dosage

The standard recommended dosage for valerian is between 300 to 600 mg of a standardized extract, ideally taken once daily before bedtime to maximize sleep benefits. Different forms of valerian, such as tea or tincture, have their own dosing regimens; for instance, one can brew a teaspoon of dried root in boiling water to prepare tea. It is advised that users consistently take valerian over several weeks to experience notable effects. Research indicates that higher doses have been tested without significant safety concerns. Timing is also critical – valerian should be consumed 1 to 2 hours prior to sleep for optimal efficacy.

FAQs

Is valerian safe for long-term use?

While valerian is generally safe for short-term use, long-term safety data is lacking, warranting caution especially for special populations.

How should valerian be taken for sleep?

It is recommended to take valerian consistently for several weeks, preferably 1-2 hours before bedtime for optimal effects.

What results can I expect from using valerian?

Users may experience improved sleep quality and reduced sleep latency, though the effects are often small and varied among individuals.

Can valerian be mixed with other medications?

Valerian may enhance the effects of other sedatives; thus, caution is advised when used in conjunction with such medications.
