The major thing that made them really identifiable was their mode of dressing that included a red attire or animal skin attire, accessories and most importantly, their eyes and bodies were decorated with white native chalk.
Native chalk is also known as nzu by the Igbos, calabash chalk in English, or ndom by the Efik/Ibibios. It is an edible clay that is found mainly in Nigeria and other West African countries.
Till date, this chalk has a huge significance to tradition and most importantly to native doctors. They usually have it smeared around one or both eyes and some other parts of their bodies.
