Description: In 1984, the National Clearing House of Poison Control Centers reported that the Australian Umbrella Tree, especially them as house plants, accounted for the top 5% of substances most ingested by children under the age of 5 years old. Little information was available on the chemical composition of this plants especially in regards to it's affect upon humans and animals. Thus, it was deemed that more information was necessitated. This article details information on 3 studies - one to address the nature of the chemical nature and preliminary effects of this plant, a pharmacological study testing for it's toxicity by testing on rats and mice and the last a 7 day study that led to the discovery that all of the mice fed a 50/50 diet of this plant and rat chow died. It was concluded that the existence of confirmed toxic compounds in the Australian Umbrella plant leaflet tissue were discovered - quinones, terpenoids, saponins, tannins, cardias glycosides and alkaloids. It's toxicity to animals via rats and mice had been demonstrated.
