Valerian Root

60 research studies on valerian root were published over nearly 40 years. Researchers determined that valerian root can likely improve sleep and reduce anxiety in many people. Valerian root has been found to help people fall asleep faster, improve their sleep quality, and spend more time in a deep sleep stage. Valerian has been used safely in doses of 300-600 mg daily for up to 6 weeks. Valerian is usually well-tolerated. Some common side effects include dizziness, drowsiness, headache, stomach upset, mental dullness, and vivid dreams.
