Natural History: This is a widely distributed species from tropical Africa through India to SE Asia. It is a large shrub with large, thick leaves. The thick milky sap from broken-off leaves and stems is conspicious. The milky sap contains cardiac glycosides and other cardenolides that impacts heart function by inhibiting the cellular sodium-potassium ATPase pump, rendering the plant unpalatable to a wide range of herbivores.
It is common by the roadsides and in dry deciduous forests.
Flowers are either white or lavender in colour, with five pointed petals.
