Written by Aparna Mallampalli , BEd (Biological Sciences), MSc (Microbiology), Diploma In Nutrition

Roots are an integral part of ancient medicine. One such traditionally used herb is the valerian root. It promotes sleep quality and is available as pills, powder, and processed roots. The herb is known for its sedative ability and is believed to exhibit minimal side effects when taken in prescribed amounts.

What happens if the valerian root is consumed for longer periods? Is it addictive? In this article, we discuss the benefits of valerian root, its potential risks, and how to reap its maximum benefits. Keep reading.

What Is Valerian Root?

Valerian (Valeriana officinalis) is a perennial plant native to Europe and Asia, and also grows in North America. Its roots are sold as a dietary supplement in the US (1). It has a strong earthy odor while its flowers have a mild scent. Valerian root extracts are also used in personal care products, cosmetics, aromatherapy, and veterinary practices. It was also used in perfumes in the 16th century. However, it is majorly used to minimize insomnia (sleeplessness) (2).

Let us understand how valerian root works. Keep scrolling.

How Does Valerian Root Work?

Valerian root works similar to Xanax (alprazolam), where it inhibits the breakdown of GABA (gamma-Aminobutyric acid) in the brain. This promotes calmness and sleep. Active constituents in valerian root — valeric acid and valerian extract — exert this action. A study suggests that valeric acid and valerian extract act by binding to the GABA-A receptors (receptors that respond when GABA is released). Both the agents enhance the response to GABA and show a significant sedative action (3),(4).

The benefits of valerian root are not just limited to promoting sleep quality. Keep scrolling to learn about all of its benefits.

Major Benefits Of Valerian Root

1. May Help With Better Sleep

Sleep plays a major role in many bodily functions (5). Hence, chronic insomnia can impact one’s overall health and well-being. Studies show that herbal medicines like valerian root may be effective in promoting sleep and preventing related disorders (6).

2. May Help Treat PMS

Premenstrual syndrome is associated with a few other health complications. Valerian root extract may reduction the emotional, physical, and behavioral symptoms of premenstrual syndrome. The regimen can be beneficial if started on the 21st day of the menstrual cycle and continued for seven days (7).

3. May Help AlleviateMenstrual Problems

Research suggests that the antispasmodic effects (ability to suppress muscle contractions) of valerian may help reduce menstrual pain. It may also reduce the need for other pain relievers if taken three times a day for two cycles (8).

4. May Help In TheTreatment Of Parkinson’s Disease

Parkinson’s disease (PD) is the second most common neurodegenerative disorder. Its major contributor seems to be oxidative stress. Studies suggest that valerian shows promise in the treatment of Parkinson’s disease by decreasing oxidative stress (9).

5. May Help Treat Anxiety Disorder

Valerian is found to help reduce anxiety. Its extract contains valerenic acid that is known to exert its anxiolytic (anxiety-relieving) action on GABA-A receptors. GABA is the primary inhibitory neurotransmitter in the central nervous system, whose deficit leads to anxiety (9).

Though valerian root offers important benefits, it also may pose certain potential risks. Keep scrolling to know more.

Possible Risks And Side Effects Of Valerian Root

The side effects of valerian root or its extracts are based on anecdotal evidence. These include:

  •  Headache

Valerian roots are used for relieving headaches. On the contrary, consuming valerian root is reported to aggravate headaches in sensitive individuals. These headaches were observed to be severe in the morning. This effect is mostly associated with the herb’s long-term intake.

  •  Dizziness

Imprudent use of valerian root may make one sleepy or drowsy. Sleepiness, mood swings, and increased drowsiness may occur with the intake of high doses of valerian root.

  •  Stomach Pain

Excess intake of valerian root is also associated with stomach pain. The pain may also be accompanied by mild digestive problems like constipation or diarrhea. Diarrhea or stomach upset occurs mainly due to the laxative effect (emptying of bowels) of the valerian root.

Note: All these side effects are usually mild and subside gradually after one discontinues the use of valerian. Consult a doctor if you experience severe side effects.

You should follow certain special precautions while consuming valerian root. These may help reduce the risk of side effects.
