Henna dye is used on nails, skin and hair by married women in the Islamic community and, traditionally, it is used by the major participants in marriage ceremonies. Henna consists of the dried leaves of Lawsonia alba, and the coloring matter, lawsone, is a hydroxy-naphthoquinone. Dyeing hair or skin with powdered henna is a lengthy procedure and, to speed up this process, Sudanese women mix a black powder (p-phenylenediamine) with henna to accelerate the fixing. The combination of henna and p-phenylenediamine is particularly toxic, and over 20 cases of such toxicity, some fatal, were noted in Khartoum alone over a 2-year period. Initial symptoms are those of angioneurotic edema with massive edema of the face, lips.
