- A plant.
It hath flowers and fruit like the spurge, and is also full of an hot sharp milky juice. The plants are angular, and shaped somewhat like the cereus or torch-thistle. It is commonly beset with spines, and for the most part hath no leaves. Miller.
- A gum resin, brought to us always in drops or grains, of a bright yellow, between a straw and a gold colour, and a smooth glossy surface. It has no great smell, but its taste is violently acrid and nauseous. It is produced in the remoter parts of Africa, whence it is sent to Sallce, and thence transported into Europe. The plant is also common on the coast of Malabar; but the Africans only know the secret of collecting the gum. It is used medicinally in sinapisms. Hill.
