In English it's just called white chalk. I've seen it in markets in Togo and Ghana where it's called ye (with a high tone) in Ewe, but there it's sold in rolls or thick sticks. It's eaten by pregnant women. Also, the eating of it is referred to as geophagia or, more generally as pica, which refers to the eating of non-food things (clay, dirt, laundry starch and so on). Popular belief is that it contains valuable mineral nutrients, but that has yet to be proven scientifically in the literature.
