Valerian

Christopher Hobbs:

“Known as “the sleep herb,” valerian has been considered an essential herb to calm the nervous system and promote healthy sleep for centuries in European herbalism. In one interesting clinical study, two groups of volunteers were outfitted with motion sensors and recorders attached to their wrists. One group was given a valerian preparation and the other a placebo pill. The next morning, researchers found that the people in the valerian group fell asleep faster and tossed and turned significantly less than those in the placebo group.

Valerian preparations are recommended by herbalists for insomnia, anxiety, nervous tension, and emotional upset, as well as for related conditions like nervous digestion and headaches. Other uses include relieving menstrual cramps, reducing heart palpitations (mixed with hawthorn or hops), and treating pain (when combined with chamomile).

Valerian has a taste of SWEET, SPICY and a temperature of WARM.”

Historical Uses

Valerian (Valeriana officinalis) has been used for over 2,000 years as a traditional herbal remedy. In ancient Greece and Rome, it was primarily employed to address insomnia, anxiety, and nervous disorders. During the Middle Ages, valerian was also used for epilepsy, headaches, and digestive issues.

Modern Clinical Uses

Herbalists and naturopaths commonly use valerian as a natural sedative to aid with:

• Sleep disorders (e.g., insomnia)
• Anxiety and stress relief
• Restlessness and nervous tension

It is often combined with other calming herbs like passionflower, lemon balm, or hops for enhanced effects.

Chemistry

Valerian contains a complex mix of compounds believed to contribute to its therapeutic effects, including:

• Valerenic acids: Modulate GABA activity in the brain.
• Iridoid glycosides (valepotriates): Provide sedative effects.
• Essential oils: Include borneol and isovaleric acid, which contribute to its distinctive odor and possibly its activity.

Pharmacology

Valerian is thought to work primarily by modulating the GABAergic system, enhancing inhibitory neurotransmission, and promoting relaxation. It may act on GABA-A receptors in the brain, similar to benzodiazepines but with milder effects. Valerian also appears to inhibit the breakdown of GABA, further amplifying its calming properties.

Clinical Trials

Research on valerian is mixed but generally supports its use for sleep and anxiety:

• A meta-analysis of clinical trials shows valerian modestly improves sleep quality, particularly with chronic use over 2–4 weeks.
• Valerian has been found to reduce sleep latency (time to fall asleep) in some studies, though results vary.
• Some studies report reductions in anxiety and stress, but effects are inconsistent compared to placebo.

Limitations in clinical trials include variability in valerian preparations, small sample sizes, and subjective reporting of outcomes.

Summary

Valerian is a well-tolerated herb with a long history of use for insomnia and anxiety. Its active compounds affect GABA activity, promoting relaxation and sleep. While scientific evidence is promising, results from clinical trials are inconsistent, warranting further research. Its safety profile makes it a popular natural remedy, but standardized formulations and consistent dosing are key to effective use.
