Valeriana officinalis, also known as valerian, is an herbal tea and supplement. It is commonly used for its sedative and anxiety-reducing effects.

Valerian is most often used for


Valeriana officinalis is a plant, commonly referred to as valerian. Traditionally, valerian roots are brewed for tea or eaten for relaxation and sedation purposes. Though valerian is one of the more popular sedative teas, current evidence suggests it is not very effective.

Valerian's primary usage is to soothe anxiety or make it easier to go to sleep.

Though scientific measurements of sleep quality showed no difference between people that supplemented valerian and people that supplemented a placebo, many participants anecdotally reported that their sleep was better when supplementing valerian. Valerian may also aid with menustral pain, since it is a spasmolytic.

Valerian is thought to enhance the signalling of one of the main sedative neurotransmitters, gamma-aminobutyric acid (GABA).

It is possible that valerian has relaxing properties independent of any actual improvements in sleep quality. High doses of valerian have been noted to cause mild sedation. Further research is needed to confirm valerian's true effects on sleep.

What else is Valerian known as?
Note that Valerian is also known as:
  • Valerian
  • Valeriana Officinalis
Dosage information

A standard dose of valerian is 450mg. Daytime supplementation should consist of 2 to 3 doses of 300mg.

Valerian supplements consist of the root, which is standardized to contain 0.8-1% valerenic acid.

Valerian should be taken an hour before bed. If valerian is being supplemented during the daytime, it should be taken with meals.
