Dicentra canadensis (Scientific name)

General poisoning notes:

Squirrel-corn (Dicentra canadensis) is a native herb found in rich woodlands in southern Ontario and Quebec. The plant contains alkaloids that are known to be toxic. However, feeding experiments on cattle using the aboveground parts, as well as the entire plant failed, to produce any symptoms other than slight restlessness and uneasiness (Black et al. 1923). See additional notes under general notes of Dicentra cucullaria.
