General poisoning notes:
Star-of-Bethlehem (Ornithogalum umbellatum), an outdoor ornamental flower, contains glycosides similar to digitalis. In some countries children have been poisoned after ingesting the flowers or bulbs. Ingesting two bulbs by an adult caused shortness of breath. The bulbs contain the highest quantity of these toxins. Cattle in South Africa (the native region for star-of-Bethlehem) have been poisoned, resulting in permanent blindness and death after ingestion. Children and family pets should be prevented from ingesting material from this plant (Cooper and Johnson 1984, Lampe and McCann 1985, Spoerke and Smolinske 1990).
