Rauwolfia (Indian Snakeroot) for Anxiety Relief

Research suggests that Rauwolfia serpentina and its primary active compound reserpine have a historical basis for use in anxiety relief, with a 2019 review explicitly noting its traditional application for anxiety and a 1995 review describing reserpine as among the first somewhat selective anxiolytics introduced in clinical practice in the early 1950s. A 1956 study examined reserpine directly in anxiety states, lending some early clinical support to this application. However, the available evidence base is limited in rigor, consisting primarily of reviews and older research rather than modern randomized controlled trials, and a 2023 systematic review of reserpine's effects found mixed findings when anxiety-related outcomes were considered. Overall, while the traditional and early clinical literature points in a supportive direction, the evidence is dated and inconsistent enough that firm conclusions about the efficacy of Rauwolfia for anxiety relief cannot be drawn from the current body of research.
