Houseplants, cultivated garden plants and ornamentals are the cause of many poisonings. However, some are attributable to native or naturalized plants. The most commonly reported plant poisonings result from curious children eating fruit and plant fragments.
A review of the available literature has shown that problems exist for doctors who have to diagnose and treat cases of plant-induced poisoning in Ontario. The initial problem is in determining whether the symptoms are indeed caused by plant toxins. The second is in acquiring a positive identification of the plant involved. In addition, well-documented literature is often not available on previous cases of poisoning and treatment. Regional Ontario Hospital control centres present in various areas of Ontario are the best sources of information.
For further information, consult your family doctor or your local Ontario Hospital Poison Control Centre.
