Tabernaemontana undulata is a tropical South American species in the Apocynaceae family. It grows as a woody shrub or small tree and shares the glossy foliage, pale flowers and white plant latex characteristic of many members of the genus.
Across the Amazon, knowledge of Tabernaemontana plants belongs to broader traditions in which botanical identity, preparation and community knowledge are closely connected. Vernacular names can cross species boundaries, which is why Sacred Plants Australia identifies this extract specifically as T. undulata.
