Balanites aegyptiaca
Once a week most Manasir women apply a "smoke mask" called "Dukhan" (دخّان) to their face and body. They burn the wood of Acacia seyal ("Talh"; طلح) in the kitchen hearth or a buried earthen pot in the courtyard. When the burning wood starts to produce smoke the woman will place herself on the "Nutu"' above the hole, covered by a big piece of coarse fabric and fumigate parts of her body until the upper skin peels off. As a result of this weekly procedure the colour of her skin will appear more pale (cf. CROWFOOT 1918:127-128). The "Dukhan" can also be used for medical purposes burning additional wood of Acacia ehrenbergiana ("Salam"; سلم) and Balanites aegyptiaca ("Higlig"; حجليج).
