The invention discloses a medicinal material tracing system. The medicinal material tracing system comprises an acquisition command module, a tracing information acquisition module and a platform server, wherein the acquisition command module is used for transmitting an acquisition command to the tracing information acquisition module of land corresponding to a command two-dimensional code; the tracing information acquisition module is used by a medicinal herb collector to scan an acquisition two-dimensional code on the corresponding land according to the acquisition command, turn on a camerato perform image acquisition in order to form tracing information, and upload the tracing information to the platform server; the platform server is used for acquiring corresponding tracing information from a database according to a tracing two-dimensional code tag after receiving a tracing request of a user, and transmitting the tracing information to a user terminal in order to finish a tracingoperation. By adopting the medicinal material tracing system disclosed by the invention, the acquisition and output of the tracing information are realized through equipment such as the tracing information acquisition module, the acquisition command module and the platform server, so that the user can inquire planting information and quality information of medicinal materials through the tracing two-dimensional codes on the packages of the medicinal materials.
