According to legends, truthberries cause those who consume them to speak only the truth until the next sunset. However, according to ArdentKabsal, the berries are harmless. But the leaves and stalks of the truthberry plant, if burned, give off a smoke that makes people intoxicated and euphoric. It appears that people often gathered the stalks for making fires. They’d eat the berries around the campfire and have a rather interesting night. Shallan remarks to Kabsal that they should be called birthberries.
