American elder
General poisoning notes:
American elder (Sambucus canadensis) is a native shrub found in the moist soils of swamps and along rivers and lakes in eastern Canada. This plant contains cyanogenic glycosides and a cathartic chemical. The plant has poisoned cattle and perhaps sheep. Children were poisoned after using the hollow stems for whistles. Ingesting uncooked berries may cause nausea (Kingsbury 1964, Muenscher 1978). Red-berried elder (Sambucus pubens) is a native shrub found from Newfoundland to Manitoba. There are unsubstantiated reports that this species may also have toxic potential. Children should not be allowed to chew the stems or berries.

Apparently, the use of the hollow stems as whistles or blowpipes has caused poisoning in children. The bark contains a cathartic. Ingesting uncooked berries can cause nausea and vomiting. Cooked are not harmful if eaten in small amounts (Kingsbury 1964).
