Marsh Marigold


The Marsh Marigold or Cowslip is usually found in the northeast and north central areas of the U.S. All of the plant is poisonous, containing an irritant oil which causes gastrointestinal irritation and diarrhea. Convulsions, hypotension and respiratory depression have been reported, but ingestion of large quantities would be necessary to produce these severe symptoms.
