Valerian

What is Valerian?

Valerian (catnip) is a plant found in large parts of Europe and Asia. In ancient Greece, valerian was already used for its beneficial physiological effects. The name Valeriana is derived from the Latin verb "valere" meaning "to be in good health."

What does Valerian do?

Valerian supplements are known for their calming and relaxing properties and are often used for stress. They can also be helpful for people who have trouble falling asleep or staying asleep*.

The exact mechanism of action of valerian supplements is not well understood. However, it is thought that they may increase levels of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, which may have a calming effect on the nervous system.

Valerian supplements are generally taken before bedtime and may take several weeks to experience their full effects.

What are the possible side effects?

Valerian supplements can cause drowsiness, so it is important not to drive a car or operate heavy machinery after taking them. We do not recommend taking Valerian supplements if you are pregnant, nursing or taking certain medications.
