Side Effects of Valerian Root

There are four possible adverse reactions to valerian root.

The use of valerian root as a natural sleep aid has become more widespread in recent years.It is used to improve poor sleep patterns, reduce menopausal symptoms, decrease anxiety, and induce relaxation.  It has a history of therapeutic use dating back thousands of years, and it is often consumed in the form of a capsule, liquid extract, or tea.

This dietary supplement is derived from the Valeriana officinalis plant, which is indigenous to Asia and Europe but may also be found growing in other parts of the world, including the United States.According to the findings of one study that compared 11 different herbal medications, valerian root was the most promising herbal therapy for treating sleep and insomnia.


Dreams that are more vivid than usual are one of the adverse effects of valerian root that people report experiencing the most often.Because it includes essential oil as well as chemicals known as iridoid glycosides, valerian has the potential to induce vivid dreams. As a result of these substances stimulating opioid receptors and serotonin synthesis in your brain, you will experience a sense of calm and an improvement in your mood.

The chemical in your brain known as gamma aminobutyric acid (GABA), which has a soothing impact on your body, may be increased by valerian, according to the findings of some studies.

Uneasy and rapid heartbeats

Heart palpitations are described as having the sensation of a racing or fluttering heartbeat.Even though they aren't dangerous most of the time, those who aren't accustomed to them could find them to be unsettling. Stress, certain medications, physical activity, or even a preexisting medical condition might be the cause of heart palpitations.It has been suggested that the root of the valerian plant was used as early as the 16th century in the treatment of heart palpitations.

Dry mouth and upset stomach

There is a possibility that valerian root may induce oral and digestive symptoms that range from mild to severe.After taking it, some persons notice an increase in the frequency of their bowel movements. It is only natural that valerian should have a long history of usage in Europe as a treatment for digestive issues such as constipation. In spite of this, the laxative actions may result in unpleasant side effects such as diarrhea or stomach distress.In a research that lasted for 28 days and included 391 individuals who were given different herbs for the treatment of sleep problems, it was found that among those who took valerian root, 18% saw an increase in diarrhea, whereas only 8% of those who took a placebo did.

Pain in the head and mental cloudiness

Although valerian root has traditionally been used to treat headaches, some patients have reported that after consuming the herb, they experienced a worsening of their headaches as well as mental cloudiness.The majority of these adverse effects seem to be caused by using this herb for an extended period of time or in large doses. In any case, symptoms may include not only an increase in the number of headaches, but also other concerns that are connected to the brain, such as excitability and unease.Even though valerian root helped them sleep better, some individuals report feeling more lethargic the morning after taking it, particularly at higher quantities. This is the case even when valerian root is used in lower amounts.As a result, you may want to consider reducing the amount you take if you have any of these symptoms.

It is important to keep in mind that the evidence for these negative effects comes from anecdotes. Therefore, there is a need for more research that is scientifically rigorous.
