ABSTRACT
244Plant ingestion is a common cause of poisoning exposures in children under age 5 in the United States, and a significant cause of toxicity in adults (Table 11.1) (22). Each year more than 15,000 Americans are poisoned by plant ingestion (16). The incidence of calls into Poison Control Centers in the United States concerning plant ingestions is estimated to be in the range of 5% to 10% of all calls (21).
