History : Mole Plant has a long history as a medicinal plant, it was known to Theophrastus (371 - 287BC). The genus was named after Euphorbes (50BC - AD23), the personal physician to the Numidian King Juba II, who is said to have discovered the toxic and curative potential of the white and milky sap in the plant. The word Euphorbus derives from the Greek eu meaning ‘good’ and phorbe meaning ‘pasture or fodder’ thus giving the meaning ‘well fed.’ Some sources suggest that Juba was amused by the play upon words and chose his physician's name for the plant because of its succulent nature and because of Euphorbus' corpulent physique.  Native of the Mediterranean, a native to southern Europe, South Africa and Asia and as far east as China. It was first cultivated as medicinal or ornamental, escaping and self-seeding along the East and West coasts of the United States. Introduced to the U.S. "to repel rodents in an orchard". 
All parts of the plant are emetic and purgative and is nowadays considered to be too toxic for it to be used medicinally. The latex in the stems has been used externally as a depilatory but it is too much of an irritant to be used safely. Beggars sometimes used the leaves to create unsightly skin sores, which would cause passers by to give them more money out of pity. The French are said to have eaten the seeds as a purgative even though they are as toxic as the plant.
The common name of Caper Spurge takes its name from the seed pods which look like capers but are very poisonous.
