European elder is a tree native to Europe and parts of Asia and Africa, and it also grows in the United States. The dried flowers (elder flower) and the cooked blue/black berries (elderberry) of the European elder tree are used in teas, liquid extracts, and capsules.
Sambucus nigra (elder) was reported to have a number of potentially useful medicinal attributes including diuretic, diaphoretic, purgative and hemostatic properties (Chiej 1988, Lust 1986). In addition, it was advocated as an effective traditional remedy for diabetes in Europe (Atkinson 1979, Palaiseul 1983).
The traditional antidiabetic plant elder contains water-soluble components capable of stimulating insulin secretion and enhancing muscle glucose uptake and metabolism. Sambucus nigra therefore represents a possible dietary adjunct for the treatment of diabetes and a potential source for the discovery of new orally active agent(s) for future diabetes therapy.
