Abstract
The Gidra-speaking Papuans of the Oriomo Plateau, lowland Papua New Guinea, consume ash of two tree species (Melaleuca sp. andAcacia mangium) as a native salt. The ashes contain 100–200 mg sodium/g ash, which is very much higher than the sodium levels in native plant ashes (except for the swamp herbEriocaulon australe) collected in other regions of the world.
