The chewing stick known as the sothiou, popular in Senegal, has important health benefits over the plastic tooth brush. Click here to find out more. I've always wondered why it isn't more popular further east in Nigeria - in terms of being a chewing stick chewed all day long as opposed to just being an African tooth brush. Perhaps its partly to do with muslim cultures over non-muslim cultures, and availability of suitable flora? Senegalese women look so languidly stylish with chewing sticks in their mouth. Thanks NI for the link.
