Possible health benefits – What does valerian root do

Sleep disorders

Valepotriates and sesquiterpenes in valerian root have sedative effects that aid in inducing sleep. Regular consumption of the root tea can treat insomnia.

The sleep-wake cycle in humans is regulated by melatonin, a hormone secreted by the pineal gland in the brain. Melatonin in the form of a drug is often given to insomnia patients for healthy sleep. However, valerian root tea is a better alternative remedy for sleep disorders in both adults and children as melatonin medications can cause unwanted side effects.

A study in insomnia patients showed that it significantly improved the quality of sleep.

Anxiety and depression

Valerian root contains valerenic acid that increases the amount of gamma-aminobutyric acid (GABA), a neurotransmitter responsible for reducing anxiety by regulating the activity of nerve cells. It has greater effects when combined with passion flower.

Application of the essential oil prepared from valerian seeds can have calming effects on the nervous system. Behavioral studies in mice supported its use in treating different types of anxiety, including social anxiety.

Some studies have shown its therapeutic effects on patients suffering from depression.


Chronic stress due to different lifestyle factors often has an impact on the overall health of an individual. A marked increase in corticosterone levels causes physical and psychological stress, causing unexpected health problems.

In a recent study, it was shown that valerian root liquid extract significantly reduced the corticosterone levels in stress-affected mice.

Muscle cramps

Valerian root tea is good for reducing cramps in the abdominal muscles, making it an effective remedy for ulcerative colitis, and menstrual pain in women.

Numerous studies have demonstrated the relaxing effects of the herb on the muscles of the uterus.

Valerian root is known to reduce the frequency of seizures in epileptic patients, owing to its sedative effects on the nervous system. Its use as an antiepileptic remedy has been supported in many animal studies.

Memory improvement

The tincture of dried valerian root can enhance memory performance and problem-solving skills in both kids and adults. A study in aged mice revealed the powerful effects of valerenic acid on memory function.

Kidney damage

Inability of the kidneys to filter the toxic wastes from the blood could lead to life-threatening consequences. Research studies in animals have shown the usefulness of valerian root powder in repairing damaged kidneys.
