Dr Dorothy Shepherd offers a guide to the medicinal treatment of first aid. For years she followed obediently the recognised, well-troden paths of antiseptic and aseptic wound treatment, with little or no medicinal aid, other than those already mentioned.She then had the opportunity to study and apply first-aid methods in surgical outpatients, private practice and a munition factory in the First World War and the later a minor ailment clinic.She gave up entirely the old methods and with the help of a devoted staff applied these comparatively new homoeopathic ideas which have proved successful.
