Tutin is a poisonous plant derivative found in the New Zealand tutu plant (Coriaria arborea, Coriaria genus, several different species). It acts as a potent antagonist of the glycine receptor,[1] and has powerful convulsant effects.[2] It is used in scientific research into the glycine receptor, and is also sometimes associated with outbreaks of toxic honey poisoning when bees feed honeydew exudate from the sap-sucking insect commonly known as the passion vine hopper, when these vine hoppers (Scolypopa australis) have been feeding on the sap of tutu bushes. Toxic honey is a rare event and is more likely to occur when comb honey is eaten directly from a hive that has been harvesting honeydew from passion vine hoppers feeding on tutu plants.[3]
