Robber's medicine, also known as golden belt, is the dried root bark or stem bark of Daphne of Daphne of Daphne family. Because its root bark and stem bark are tough and not easy to break, and because it is tied around the waist as a belt, it can cure low back pain on weekdays, so it is also called "robber medicine". Moreover, because of its remarkable curative effect on traumatic injury, thieves can be treated with it after being beaten.
