General poisoning notes:

Tree-of-heaven (Ailanthus altissima) is an ornamental found in the warmest parts of Canada. Exposure to the leaves may have caused dermatitis in humans and it is suspected of being a poisonous plant as well. However, convincing documentation of poisoning is lacking. The tree has been suspected of causing gastroenteritis. (Muenscher 1975, Mitchell and Rook 1979).
