Sambucus is a genus of flowering plants in the family Adoxaceae, its species commonly called elder or elderberry. There are between 5 and 30 species of deciduous shrubs, small trees and herbaceous perennial plants.
The ripe and cooked berries (pulp and skin) of most species of Sambucus are edible. However, most uncooked berries and other parts of plants from this genus are poisonous. Sambucus nigra is the only variety considered to be non-toxic, but it is still recommended that its berries be cooked slightly for culinary purposes.
The leaves, twigs, branches, seeds, and roots of Sambucus plants can contain a cyanide-inducing glycoside. Ingesting a sufficient quantity of cyanide-inducing glycosides can cause a toxic buildup of cyanide in the body.
