Cyphostemma ternatum

Cyphostemma ternatum is a perennial climbing herb that grows up to two metres and is spread from north-east Africa to southern Arabia. The name ternatum is Latin for arranged in threes and refers to its leaves. It is a succulent vine with alternate, serrated leaves of three leaflets, pale greenish-yellow flowers in clusters opposite the leaves, and a fleshy ovoid berry that ripens bright red. It grows near sea level, in bushland, grassland and riverside forest. The page says it is edible. In southern Arabia the leaves were traditionally boiled into a green mush, with a peppery and acrid taste. The ripe fruit is edible once the pip is removed, because the pip is quite hot. The root can be eaten raw but is said to be better cooked. In traditional herbal medicine in Arabia the juice of the cooked leaves, with salt, was applied as a poultice to treat footrot.
