Nothofagus nuda

Trisyngyne nuda is a species of plant in the Nothofagaceae family. It is endemic to Papua New Guinea. It is threatened by habitat loss. T. nuda was known as Nothofagus nuda prior to 2013.[1]

In 1927, T. nuda was reported by J. R. Croft to account for 949 deaths throughout Papua New Guinea.[2] The plant is traditionally used as an herb in culinary dishes throughout the Puri Puri[disambiguation needed] tribes of the Papua New Guinea highlands but results in hypoglycemic shock after ingestion of large doses.[3] Croft reported that wives within the polygamous tribes of the Puri Puri used the herb to poison the patriarchs during tribal disputes that coincided with the winter solstice.[4]

Scientists in Macao Laboratory isolated the active molecule of the plant in late 2006.[5] The molecule was determined to be an IRS-1 adaptor molecule involved the insulin response cascade.[6][7][8]
