5/5 - (1 vote)

Valerian has served for millennia as an adjuvant for nervous and sleep problems, as it is a natural relaxant. Its use dates back to the ancient Greek and Roman empires, where even Hippocrates, considered the father of medicine, had pointed it out as effective to treat headaches, nervousness, tremors and heart palpitations.

It is estimated that valerian has more than 120 chemical components, including antioxidants, valerenic acid and isovaleric acid, which makes it a common ingredient in herbal medicines against insomnia and anxiety.

Although it is a very popular remedy in many parts of the world, most people do not know the correct way to use this plant with sedative properties. This article will shed light on this matter

  • Division: Magnoliophyta
  • Class: Magnoliopsida

Its scientific name is valeriana officinalis, but it is known simply as valeriana. It is a flowering medicinal plant believed to be native to Europe and Asia

The root of this herb, which is characterized by a strong earthy odor due to the concentration of volatile oils and other compounds, is commonly used for medicinal purposes, particularly to treat sleep disorders, and is the basis of many pharmaceuticals with sedative properties.

Properties of valerian

Valerian is noted for its sedative and anxiolytic properties, which gives it the ability to relax the nervous system and the brain. Hence it is often used to mitigate the effects of stress, anxiety, insomnia and nervousness.

Among its components is valerenic acid, which is possibly the one that affects the receptors of gamma-aminobutyric acid (GABA), the main neurotransmitter that inhibits the central nervous system, it also has some antioxidants such as hesperidin and linarin.

The chemical composition of valerian root includes mainly sesquiterpenes and iridoids, but it also contains glucids, starch, fatty acids, phenolic acids, glutamine and arginine, traces of alkaloids, resin, flavonoids, triterpenes and essential oil rich in monoterpenes.

How does valerian work, and what are its benefits?

Substances such as valerenic acid, isovaleric acid and antioxidants give valerian its sedative effects.

The root of this plant, in particular, has been the subject of multiple studies, due to its interaction with gamma-aminobutyric acid (GABA), a chemical component responsible for regulating nerve impulses in the brain and nervous system

According to the scientific journal Neuropharmacology, the valerenic acid in valerian decreases the degradation of brain GABA and, therefore, produces a feeling of tranquility.

Some clinical studies carried out to evaluate the efficacy of valerian as a sleep inducer have shown that it favors the conciliation of sleep. On the other hand, other scientific research supports the anxiolytic and sedative action of valerian to improve sleep disorders.

On the other hand, components such as hesperidin and linarin are also associated with the sedative and anxiolytic capacity of this plant. Thanks to all its chemical properties, the following benefits are attributed to it:

  • Controls states of stress
  • Reduces states of nervousness and restlessness.
  • Regulates heart rate
  • Relieves menstrual pain.
  • Reduces chronic fatigue syndrome.
  • Improves sleep quality

when to take valerian?

Because it is a plant that acts as a sedative agent, and has the effect of relaxing the nervous system and the brain, it is often recommended for people with sleep disorders, or to relieve stress and anxiety.
