General poisoning notes:

Osage-orange (Maclura pomifera) is occasionally planted as an ornamental shrub in the warmest parts of Canada. The milky sap causes dermatitis in sensitive individuals. It is unclear whether the sap is an irritant, is sensitizing, or both (Muenscher 1975, Mitchell and Rook 1979).
