A Mauritanian man carries a bowl of fresh camel milk to a container in the capital Nouakchott, March 24, 2007. With its hunched back, protruding teeth, facial hair and distinctive body odour, the camel may not seem an ideal model for beauty products. Think again, says Nancy Abeiderrahmane, who runs a camel dairy in the Saharan state of Mauritania and says vitamin-rich camel milk can cleanse the body both inside and outside.
