Dosage information is for harm reduction purposes only. Individual sensitivity varies greatly. Always start with the lowest effective dose and work your way up slowly. Never eyeball doses — use a milligram scale.
## Overdose Profile Fatal overdose from valerian root alone has never been documented. The therapeutic index is extremely wide. In the most significant reported overdose case, a patient ingested approximately 20 times the recommended dose (approximately 20 grams of dried root preparation) and experienced only mild symptoms: fatigue, abdominal cramping, chest tightness, lightheadedness, tremor of the hands, and dilated pupils. All symptoms resolved within 24 hours without medical intervention. ## Combination Overdose Considerations While valerian alone poses minimal overdose risk, combining it with other CNS depressants theoretically increases risk: - **With alcohol**: excessive drowsiness, impaired coordination, and prolonged sedation - **With benzodiazepines or Z-drugs**: additive CNS depression; theoretical risk of excessive sedation, though no fatalities have been attributed to this combination - **With opioids**: additive sedation; the contribution of valerian to respiratory depression is likely negligible at standard doses, but caution is warranted ## When to Seek Medical Attention Seek medical attention if someone has ingested a very large amount of valerian (multiple bottles) and exhibits confusion, difficulty breathing, severe drowsiness, or if valerian was taken in combination with pharmaceutical sedatives or alcohol in quantity.
