My Dad will often tell of how his mother was prescribed a bottle of Guinness every day for anaemia. The Guinness would be poured into a glass and then a hot poker from the fire was plunged into it. Needless to say, this caused both foaming and warming but that is how it was drunk.
Maybe it was thought that the poker treatment increased the iron content? <!-- s:?: --><img src="{SMILIES_PATH}/icon_question.gif" alt="
