Toxicity

Inedible parts of the plant, such as the leaves, stems, roots, seeds and unripe fruits, can be toxic due to the presence of

s. Traditional methods of consuming elderberry includes jams, jellies, and syrups, all of which cook down the fruit and strain out the seeds. Unpublished research may show that ''S. canadensis'' (American elderberry) has lower cyanide levels than apple juice, and that its fruit does not contain enough beta-glucosidase (which convert glucosides into cyanide) to create cyanide within that biochemical pathway. For comparison, assuming ''S. nigra'' has levels of no more than 25 micrograms of cyanogenic glycosides/milligram of berry weight, assuming all of the glycosides were converted to cyanide, and assuming a toxicity of 50 mg for a 50 kg vertebrate, one would need to eat 2 kilograms (~4.4 pounds) of berries in one sitting to reach the lower limits of lethal toxicity (1 mg cyanide/kg of weight). For the upper limits (3 mg/kg), one would need to eat 6 kg or ~13 pounds.

Uses

The flower called elderflower is edible, as are the ripe berries, although cooking may be preferred to inhibit intake of glycosides, which are associated with potential toxicity. A drink can be made from soaking the flower heads in water for eight hours. Other uses for the fruit include wine, jelly and dye. The leaves and inner bark can be used as an
