First Aid & Prevention

First 30 Minutes

  • • Rinse mouth with clean water if large amounts of plant material are ingested
  • • Monitor exposed cats for unusual behavioral changes or gastrointestinal distress for 2 hours post exposure
  • • Remove any remaining valerian plant material from the reach of pets to prevent overconsumption

Contact Vet Immediately

  • • If your cat exhibits prolonged hyperactivity, lethargy, or repeated vomiting after ingesting large quantities of valerian
  • • If any animal shows persistent diarrhea or abdominal pain after valerian ingestion
  • • If you are unsure of the quantity of valerian ingested by your pet or livestock

Prevention

  • • Store dried valerian or valerian supplements out of reach of pets, especially cats
  • • Do not add valerian to feed rations for any domestic or farm animals
  • • Confirm plant identification before handling to avoid confusion with toxic lookalike species

Treatment & Prognosis

  • • Supportive care including oral fluids if mild gastrointestinal distress occurs
  • • Symptomatic management of any observed adverse behavioral or physical effects

Other Valerian species Valeriana spp.
Morphologically very similar to Valeriana officinalis aggr.; other Valeriana species may have different chemical profiles and variable toxicity levels
