Over the last week I have seen several patches of Butterbur in flower, usually along river banks in the Peak District. I took these photos yesterday from the Derwent Valley Heritage Way footpath between Calver and Baslow. As with all of the spring flowers this year it is late coming into flower.
Butterbur is a member of the daisy family and has been used for centuries in folk medicine for a wide variety of illnesses. It has been used as a muscle relaxant, and to treat fever, coughs, headaches, wounds, stammering, asthma and stress. Not all these uses are supported by scientific research.
