Prestonia is a genus of plants in the dogbane family Apocynaceae. First described as a genus in 1810, it currently includes 63 species of lianas. They are native to Mexico, Central America, South America, and the West Indies. Their flowers are tube or funnel shaped and have 5 petals, often with noticeable annular coronas. Prestonia amazonica, which is often named as a hallucinogenic plant, belongs to this genus.
Species in Prestonia can be found in the neotropics of Mexico, Central America, South America, and the West Indies. They extend as far north as northeast Mexico and as far south as northern Argentina. Colombia and Brazil have the most species with 25 and 23 known species respectively. They can be found at elevations ranging from sea level to as high as 2800m.
The fresh roots, stems, and leaves of Prestonia mollis are known to be used by people in southern Ecuador (Loja and Zamora-Chinchipe provinces) to disinfect, to treat wounds, and to treat cancer.
