Valerian Root's Impact: Reducing Rem Sleep Or A Relaxing Myth?

Valerian root is a popular herbal sleep aid available in tea, capsules, and tinctures. It is an herb native to Asia and Europe, but it can also be found in North America. The root of the plant is used for different purposes and has a distinct scent that many people find unpleasant. Valerian root contains multiple chemical compounds that may impact the human brain and body, but researchers haven’t completely pinpointed which compounds are responsible for its effects.

Valerian root has been found to improve sleep and reduce anxiety in many people. It helps people fall asleep faster, improves their sleep quality, and increases the time spent in a deep sleep stage. However, some studies have found that valerian root had no effect or an insignificant effect on sleep. The American Academy of Sleep Medicine (AASM) advises against the use of valerian root for treating chronic insomnia due to the lack of evidence for its effectiveness and safety.

Valerian root is generally considered safe for adults, even when taken regularly for up to 28 days. However, it is not recommended for those taking sedatives or other anti-anxiety or sleep medications, as well as for pregnant or nursing women and children under three years old.

Valerian root's impact on REM sleep in humans

Valerian root is an herb native to Asia and Europe, but it can also be found in North America. It is a popular herbal sleep aid available in tea, capsules, and tinctures. The root is used for different purposes and has a distinct scent that many people find unpleasant.

Valerian root contains multiple chemical compounds that may impact the human brain and body, but researchers haven’t completely pinpointed which compounds are responsible. Most likely, multiple components act together to provide effects. Researchers have identified the following active compounds in valerian root: iridoids (also called valepotriates), essential oils (including valerenic acid and valeric acid), and GABA (at low levels).

Valerian root has been found to reduce brain activity in the motor cortex in response to stimulation, as well as change how brain waves in different parts of the brain work together in response to stress and anxiety. It also impacts GABA and serotonin receptors, which are involved in mood and sleep.

After analyzing 60 research studies, researchers determined that valerian root can likely improve sleep and reduce anxiety in many people. Valerian root supplements have been found to help people fall asleep faster, improve their sleep quality, and spend more time in a deep sleep stage. However, some studies found that valerian root had no effect or an insignificant effect. To see improvement, people might have to take valerian root regularly, rather than once in a while or as needed.

The American Academy of Sleep Medicine (AASM) advises against the use of natural sleep aids, including valerian root, when treating chronic insomnia, due to the lack of evidence for their effectiveness and safety. Chronic insomnia is a sleep disorder in which a person has trouble falling or staying asleep three or more nights per week for at least three months. During this time, they also experience daytime fatigue or difficulty concentrating.

Valerian root is considered a safer alternative to prescription sleep aids, and many studies have found it to be a safe natural sleep aid. Researchers have found that taking valerian root regularly for up to 28 days doesn't cause problems for most adults. However, the AASM also recommends against using valerian root for chronic insomnia because they've determined there isn't enough research demonstrating its safety or efficacy.

There is no official dosage recommended for people wanting to take valerian root. Most research studies of valerian root's effect on sleep have people take 300 to 600 milligrams, once per day, on a regular basis.

Valerian root's impact on REM sleep in rats

Valerian root is known to be one of the most famous herbal supplements for treating anxiety and insomnia. However, there is limited scientific research on how it affects sleep patterns, particularly regarding its impact on REM sleep. To address this knowledge gap, a study was conducted on the effects of valerian extract on sleep spindles and induced anxiety in a chronic neuropathic pain model in rats.

The study involved 24 male rats divided into three groups: a neuropathic group, a sham group, and a group with neuropathic conditions treated with valerian. The rats underwent electrode implant surgery to record electroencephalogram and electromyography waves. The results showed that valerian treatment reduced allodynia induced by neuropathy and had a positive impact on sleep quality.

Specifically, valerian treatment decreased REM sleep and increased non-REM sleep in the neuropathic group. Additionally, there was an increase in sleep spindle density and spindle frequency, even in the presence of neuropathic conditions. These findings suggest that valerian root may have a role in improving sleep quality, particularly by modulating REM and non-REM sleep cycles.

Another study by Shinomiya et al. (2005) also investigated the effects of valerian extract on the sleep-wake cycle in sleep-disturbed rats. They found that valerian extract significantly reduced sleep latency at doses of 1000 and 3000 mg/kg. However, it had no significant effect on total wakefulness, non-REM sleep, or REM sleep, even at the higher dose.

In conclusion, while valerian appears to have sleep-inducing and sleep quality-enhancing effects, its specific impact on REM sleep in rats remains somewhat unclear, with one study showing a decrease and the other showing no significant effect. Further research is needed to fully understand the mechanisms by which valerian affects sleep patterns.

The safety of valerian root

Valerian root is generally considered safe for most people when used at the recommended doses. However, it is not recommended for pregnant or breastfeeding women as the risks to the developing baby are unknown. It is also not recommended for children under three years old as its safety has not been tested in this age group.

Valerian root is likely to cause drowsiness and, therefore, should not be taken when driving or operating machinery. It should also not be combined with alcohol, other sleep aids, antidepressants, or sedative drugs. If you are taking any medication, it is important to consult a healthcare professional before taking valerian root.

While valerian root is considered relatively safe, it is not suitable or safe for everyone. Mild side effects have been reported, including stomach issues such as diarrhoea and stomach ache, and a metallic taste in the mouth. Rare cases of liver injury have also been associated with valerian root use, although these cases usually involved the use of valerian in combination with other herbs.

To ensure the safe and effective use of valerian root, it is important to consult a healthcare professional and follow the recommended dosage guidelines. The recommended dosage for insomnia is 300 to 600 milligrams, taken 30 minutes to two hours before bedtime. For anxiety, the recommended dosage is lower, typically 120 to 200 milligrams, taken three times per day, with the last dose before bedtime. It is important to note that valerian root seems to work best after taking it regularly for two or more weeks, and it should not be taken for more than a month without consulting a doctor.

The efficacy of valerian root

Valerian root, scientifically known as Valeriana officinalis, is a popular herbal medicine used as a sleep aid. It is a flowering plant native to Asia and Europe that has been used to treat sleeping disorders since the Middle Ages.

Valerian root is considered a safe and effective herb to promote sleep and prevent associated disorders. It may also help reduce anxiety and improve symptoms of obsessive-compulsive disorder (OCD), among other benefits. However, more research is needed to confirm these effects.

Valerian root is generally considered safe for most people when used at recommended doses. However, it may interact with certain medications, and it is not recommended for pregnant or breastfeeding women or children without medical supervision.

To ensure the best results, valerian root should be taken as directed by a healthcare professional. The recommended dose for improving sleep quality is 450-1410 mg of whole valerian root per day for 4-8 weeks. For tension relief, experts suggest a dose of 400-600 mg of valerian extract or 0.3-3 grams of valerian root up to three times per day.

In summary, valerian root has been shown to improve sleep quality and reduce anxiety in several studies. However, the quality of herbal extracts and the specific preparation methods can impact its efficacy. More research is needed to standardize valerian products and fully understand their effects on human health.

The active compounds in valerian root

Valerian root contains a variety of chemical compounds that are thought to act synergistically to exert sedative effects. The active compounds in valerian root include:

• Alkaloids: actinidine, chatinine, shyanthine, valerianine, and valerine
• Gamma-aminobutyric acid (GABA)
• Iridoids, including valepotriates: isovaltrate and valtrate
• Sesquiterpenes (contained in the volatile oil): valerenic acid, hydroxyvalerenic acid, and acetoxyvalerenic acid
• Flavanones: hesperidin, 6-methylapigenin, and linarin

Valerenic acid is the main constituent of valerian root and is thought to be responsible for its sedative and anxiolytic effects. It is a strong inhibitor of cytokine and NF-κB activation and has been found to increase the release of GABA, a neurotransmitter involved in sleep regulation. Valerenic acid may also inhibit the enzyme that breaks down GABA, thereby increasing GABA concentrations and decreasing central nervous system activity.

Other compounds in valerian root, such as valerianine and valerianin, may also interact with GABA receptors and have sedative effects. Additionally, valerian root contains flavonoids such as linarin, which have been found to have sedative and sleep-enhancing properties.

The effectiveness of valerian root is thought to depend on the form and preparation of the product. For example, the highest concentration of valerenic acids has been found in powder capsules, while the lowest amount has been found in tinctures and teas.
