The Guelder Rose berries are 'mildly' toxic when raw and are eaten raw in many European countries (you'd have to eat a lot to have serious symptoms) but the plant has many medicinal uses. The bark is used as a treatment for cramp (hence one of its names - 'cramp bark'). It is one of only two native British viburnum shrubs and was used in prehistoric times for arrows and more recently for skewers and pipe stems.
