Valerian: Questions – Answers

Answers to Patients’ Frequently Asked Questions

What will this herb do for me?

Valerian is classified as a mild, sedative herbal medicine. It can reduce the time it takes to fall asleep at night and may also relieve stress and anxiety during the day. When added to a bath, it may increase relaxation, wellbeing and reduce some forms of pain.

When will it start to work?

For some, it works within an hour of the first dose; however, research suggests it works best after several weeks of regular use.

Are there any safety issues?

From the available evidence, next-day drowsiness is uncommon and physical addiction highly unlikely. Taking high doses during the day may increase drowsiness, so care is needed when driving a car or operating heavy machinery.
