Sambucus species are now undergoing significant IY because they contain a number of plant lectins ave hemagglutinin characteristics. These corn?s are useful in blood typing and defining other atologic characteristics.
Elder flowers are considered to diuretic and laxative properties; however, the spe?compounds responsible for these activities have not been well established. The compound sambuculin A and a mixture of alpha- and beta-amyrin palmitate have been found to exhibit strong anti hepatotoxic activity against liver damage induced experimentally by carbon tetrachlo?ride.
Because of the cyanogenic potential of the leaves, extracts of the plant may be used in foods, provided HCN levels do not exceed 25 ppm in the flavor. Toxicity in children who used pea shooters made from elderberry stems has been reported.
One report of severe illness following the ingestion of juice prepared from elderberries has been recorded by the Centers for Disease Control? Persons attending a picnic who ingested several glasses of juice made from berries picked the day before reported nausea, vomiting, weakness, dizziness, numbness and stupor. One person who consumed five glasses of juice was hospitalized for stupor. All recovered.
