Psychotria viridis is a shrub from the coffee family, Rubiaceae. It has many local names, including Chacruna and Chacrona (from Quechua chaqruy, "to mix").
It is a close relative of the Ecuadorian Psychotria carthagensis, known as samiruka (amiruca), and some dispute remains as to whether or not the two are actually separate species.
