Danewort (Sambucus ebulus), also known as dane weed, or European dwarf elder, is a herbaceous species of elder, native to southern and central Europe.
Sambucus ebulus grows to a height of 1–2 m. The leaves are opposite, pinnate, 15–30 cm long, the stems terminate in a corymb 10–15 cm diameter with numerous white (occasionally pink) flowers.
The fruit is a small glossy black berry 5–6 mm diameter and the ripe fruit give out a purple juice. The plant's stems and leaves turn red in autumn and this may explain the link with blood.
Sambucus ebulus fruits have been used in the traditional medicine for treatment of disorders of the respiratory tract and fever.
