Toxidromes associated with the most common plant ingestions.

Toxicology and botanical references describe a myriad of symptoms associated with the ingestion of plants. The symptoms are based largely on a limited number of case and anecdotal reports or the personal experience of authors: there is little consistency between and among the references. This project compiled a list of symptoms associated with common plant ingestions. Exposure data from the American Association of Poison Control Centers were queried to identify the 20 most commonly ingested plants and the most frequent symptoms associated with those ingestions; 768,284 plant exposures were analyzed and symptoms occurred in 53,081 patients. The 20 most frequently ingested plants accounted for 54.2% of the reported symptoms. Most plant ingestions were not associated with the development of symptoms.
