Calotropis procera

Calotropis procera (known by the common names calotrope, apple of Sodom, Sodom apple, mudar, or osheror stabragh) is a species of flowering plant in the dogbane family, Apocynaceae, that is native to North Africa, Tropical Africa, Western Asia, South Asia, and Indochina. It is commonly known as apple of Sodom, a name derived from the Hebrew Tapuah Sdom. The green globes are hollow but the flesh contains a toxic milky sap that is extremely bitter and turns into a gluey coating resistant to soap.
