Fontainea picrosperma, commonly known as the blushwood tree, is a rainforest tree in the family Euphorbiaceae endemic to Queensland in Australia, where it grows on the Atherton Tablelands.
An anti-cancer drug known as EBC-46 has been developed from an extract of the fruits of Fontainea picrosperma. Trials have shown that it has activity against four different types of tumours, including basal-cell carcinoma, melanoma, squamous cell carcinoma and breast adenocarcinoma. The fruits are toxic to humans if eaten.[1]
