Three Canadian plants contain a poisonous sap that is
the causative agent of Rhus-dermatitis, the most widespread skin disorder
affecting Canadians.
The three poisonous plants are poison ivy (Rhus radicans L.), western
poison oak (Rhus diversiloba T. & G.), and poison sumac (Rhus vernix
L.). Poison ivy is the most common and widespread plant of the three.
Caution
dead plants of poison ivy can still cause dermatitis
and must be handled with care.
