Calotropis procera is a species of flowering plant in the family Apocynaceae that is native to North Africa, tropical Africa, Western Asia, South Asia, and Indochina. The green fruits contain a toxic milky sap that is extremely bitter and turns into a gluey coating which is resistant to soap.
The milky sap contains a complex mix of chemicals, some of which are steroidal heart poisons known as `cardiac aglycones`. These belong to the same chemical family as similar ones found in foxgloves Digitalis purpurea.
The plant contains steroidal components that are the cause of its toxicity. In the case of the Calotropis glycosides, their names are calotropin, calotoxin, calactin, uscharidin .
