Herbs - Valerian - Contraindications / Precautions / Warnings

Valerian can have a sedating effect on the body and can cause drowsiness. Do not use while driving, operating heavy/precision machinery, or performing any other activity requiring a high, acute, level of awareness.

Do not take valerian with prescription barbiturates as effects may be compounded.

Valerian causes hyperactivity in a small percentage of people.

Potential toxicity from valepotriates is avoided due to the rapid degradation of these constituents during preparation. Oral ingestion of valepotriates is countered by poor absorption of the toxic elements.

Prolonged use at high doses may lead to headaches and palpitations.
