Ingested seeds generally remain intact as they pass through the gastrointestinal tract without releasing any toxin and causing any toxicity. However, if the seeds are chewed, pulverized, or digested (i.e., if passage through the gastrointestinal tract is delayed), then the toxin is absorbed by intestinal cells, causing mild to severe gastrointestinal toxicity. Symptoms depend upon the amount of toxin exposure and include nausea, vomiting, abdominal cramping, diarrhea, and dehydration. Variations in the severity of toxicity may be related to the degree to which the seeds are ground or chewed before ingestion. Parenteral administration (such as by injection or inhalation), or perhaps large ingestion, may produce life-threatening systemic findings, including multisystem organ failure, even with small exposures.
