It's edible for humans but it has a rather bland taste so it's usually just ignored. During a trek in Bokod, a local showed us how to make them more palatable to human taste buds. He said pick the very ripe ones. He means the fruits na medyo squishy when you press them and parang nagse-separate yung skin if you apply pressure.
He then cleaned the skins, cut up the flesh in small pieces, then mixed them with good amounts of muscovado sugar. Tastes nice because the muscovado gave it a sweet flavor. He also said that wild figs can be preserved by pickling them in a jar.
