Edible Uses

Edible Parts: Seedpod Edible Uses: The thick fleshy unripe seedpods, which resemble green plums, are eaten raw or cooked[2, 177, 183]. They are highly esteemed[85]. The pods are about 25mm in diameter[235].

Known Hazards

Many members of this genus contain toxic glycosides[65]. All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage[85]. A number of species can also accumulate toxic levels of selenium when grown in soils that are relatively rich in that element[65].
