It is a traditional crop of Southeast Asia and a popular vegetable in Malay cuisine where leaves and young stems are eaten raw, steamed, boiled with beansprouts, cooked with eggs or added to soups. It is recommended to crush and soak the leaves in water to wash away the sap before cooking. The plant especially its mature leaves is rich in minerals and vitamins. A recent trend sees growers force-feeding plants with extra fertilizers and water and using shade cloth to make them grow more rapidly, resulting in more tender shoot-tips that have few leaves and are asparagus-like in texture. Leaves are also used as food colouring in Indonesia. Flowers and fruits can be eaten as well. The plant contains considerable amounts of papaverine, an alkaloid acting as smooth muscle relaxant.
