Sweet leaf (Sauropus androgynus) belongs to the the Euphorbiaceae (the Spurge family). It is a small evergreen tree that is native to Southeast Asia. This tree grows in the tropical forests and can reach 1.5-2.5 m in height. The stems are much-branched and upright. The leaves are dark green, ovate to lanceolate with acute tips. The small, dark red flowers bloom in the axils. It has been cultivated as one of the most popular leaf vegetables in South Asia and Southeast Asia. However, a study has suggested that excessive consumption of its leaves can cause lung damage, due to the alkaloid papaverine.
