Valerian

What is Valerian?

Valerian, or Valeriana officinalis, is a European herb that has been used for centuries as a natural sleep aid. It is known for its calming properties and has traditionally been used to treat sleep problems and anxiety. Valerian root, which is the part of the plant most commonly used, contains several bioactive compounds believed to contribute to its effects on the body. Its popularity has increased as more people seek natural alternatives to synthetic medications for sleep and relaxation.

How does it work in the body?

Valerian primarily acts by affecting the GABA (gamma-aminobutyric acid) system in the brain. GABA is a neurotransmitter that has an inhibitory effect on the nervous system, helping to reduce stress and anxiety. Valerian may increase GABA levels in the brain, which in turn can contribute to improved sleep quality. Additionally, studies have shown that valerian can influence other neurotransmitters such as serotonin and melatonin, further supporting its role as a sleep aid.

Scientific benefits

Several studies have investigated valerian's effects on sleep and anxiety. A review article published in Sleep Medicine Reviews concludes that valerian can improve sleep quality and reduce the time it takes to fall asleep. Another study from 2016 showed that participants taking valerian reported a significant reduction in sleep problems compared to placebo.

• A 2015 study published in Journal of Ethnopharmacology demonstrated that valerian may have a positive effect on sleep quality in individuals with sleep disorders.
• Research has also shown that valerian can be effective against anxiety, with a study published in Phytotherapy Research showing it reduced anxiety levels in participants.

Dosage and recommendations

The recommended dosage of valerian varies depending on the preparation used. Generally, a dose of 300-600 mg of valerian root extract is recommended, taken 30 minutes to two hours before bedtime. It is important to follow the instructions on the label of the specific supplement and to consult a doctor before starting valerian, especially if you are already taking other medications.

Best sources and forms

Valerian is available in several forms, including:

• Capsules and tablets: These are common and easy to dose.
• Tea: Valerian tea can be a soothing option for those who prefer to drink their supplements.
• Tinctures: Liquid extracts that can be taken directly or mixed with water.

It is important to choose products from reputable manufacturers to ensure quality and purity.

Side effects and warnings

Although valerian is generally considered safe, some individuals may experience side effects. Common side effects include:

• Drowsiness during the day

• Allergic reactions (rare)

It is also important to note that valerian can interact with certain medications, especially sedatives and antidepressants. People with liver problems or pregnant and breastfeeding women should avoid taking valerian without medical advice.
