Plant exposures: a state profile of the most common species.

Plant exposures are the fourth most common cause of poisoning and 86% of those exposures involve the pediatric population. The large number of plant-related exposures and the lack of knowledge about plant toxicity has led to plant paranoia and considerable educational efforts to reduce the number of exposures. These efforts are often dictated by misconceptions and folklore. AAPCC TESS data on all plant exposures for the years 1985-1994 were electronically analyzed by plant species and state to establish a frequency distribution in the US. Aggregate national data was also tabulated. A total of 912,534 plant exposures were analyzed to tabulate the top 30 plant exposures for each state. Philodendron species were the most common exposures, followed by Dieffenbachia species, Euphorbia pulcherrima, Capsicum annuum and Ilex species. There were considerable differences between states relating to indoor vs outdoor plants and native vs introduced varieties. Plant exposures are common and poison information centers devote significant clinical service and educational effort to manage them and to enhance public awareness. Recognition of specific plant species and exposure frequency in a poison center region can be a basis for staff education and the development of appropriate poison prevention education brochures. This can direct better utilization of poison center's resources.
