Valerian root is one of the most common natural sleep aids available.

It’s used to improve poor sleep patterns, alleviate anxiety, ease menopausal symptoms, and promote relaxation. Used medicinally for thousands of years, it’s commonly taken as a capsule, liquid extract, or tea.

This supplement comes from the herb Valeriana officinalis, which is native to Asia and Europe but also grows in other countries like the United States.

One review of 11 herbal medicines concluded that valerian root was the most promising herbal medicine for sleep and insomnia.

Heart palpitations

Heart palpitations feel like a rapid or fluttering heartbeat.

Though typically harmless, they can be worrisome if you’re not used to them. Heart palpitations may be triggered by stress, medication, exercise, or a medical condition.

Historical reports suggest that valerian root was used to treat heart palpitations as far back as the 16th century.

Ironically, some people have experienced heart palpitations as a side effect of using or discontinuing valerian root. However, these reports are anecdotal and not based on research.

As such, human studies are needed to verify its potential effects

Some people claim that valerian root causes heart palpitations or increased heart rate, but the evidence for this is mostly anecdotal.

Valerian root is a popular sleep aid that’s widely considered safe.

Still, some people have reported several minor side effects, such as vivid dreams, heart palpitations, dry mouth, digestive upset, headaches, and mental fogginess.

If you’re experiencing any side effects that you think could be related to valerian root, consider reducing your dosage.

Moreover, if you’re uncertain about how to use this herb, speak to your healthcare provider for more guidance
